Definitions

  • the present invention relates generally to the use of one or more low-potency sweetener(s) to improve one or more sweetness characteristics of one or more high- intensity sweetener(s).
  • the present invention thus also relates to compositions comprising a mixture of at least one high-intensity sweetener and at least one low- potency sweetener.
  • the present invention further relates to the use of a combination of at least one high-intensity sweetener and at least one low-potency sweetener as a sweetness modifier wh+en used in combination with at least one other sweetener and/or as a sweetener.
  • the present invention further relates to the use of one or more mogroside(s) as a sweetness enhancer in sweetened compositions and said sweetened compositions.
  • the present invention further relates to methods of making the sweeteners and compositions disclosed herein.
  • Sweetness in comestible products that is products intended to be taken by mouth either for permanent ingestion or temporarily for expectoration, is often a desirable characteristic.
  • sweetness has been provided by the addition of one or more sweeteners, particularly low-potency, nutritive sweeteners such as sucrose (table sugar), fructose, glucose, xylose, arabinose, rhamnose, sugar alcohols such as erythritol, xylitol, mannitol, sorbitol and inositol as well as sugar syrups such as high fructose corn syrup and starch syrup. These deliver considerable sweetness without any undesirable aftertaste.
  • nutritive sweeteners such as sucrose (table sugar), fructose, glucose, xylose, arabinose, rhamnose, sugar alcohols such as erythritol, xylitol, mannitol, sorbitol and inositol
  • sugar syrups such as high fructose corn syrup and starch
  • High-intensity sweeteners have been used for this purpose.
  • High-intensity sweeteners may be natural or artificial and have a sweetness that can be several hundred times that of sucrose and thus can theoretically replace a much larger quantity of sugar in a composition.
  • high-intensity sweeteners include sucralose, saccharin, aspartame, acesulfame potassium (AceK), neotame, advantame, sterviol glycosides, including stevioside, rebaudioside A, rebaudioside D or steviol glycoside mixture preparations with rebaudioside A and/or stevioside as predominant components.
  • these substances generally have the drawback that they may impart undesirable off-tastes to comestible products, typically bitter, metallic or liquorice tastes, or an undesirable lingering sweetness.
  • Sucrose imparts an intense upfront sweetness that is short in time and decreases without any significant off-notes or aftertaste.
  • Rebaudioside M (Reb M or reb M) has been used as an alternative sweetener to sucrose to reduce the caloric value of a comestible product.
  • Reb M has a delayed and slight upfront sweetness as compared to sucrose, which transitions to an intense sweet impact followed by a quick decrease in sweetness and undesired lingering off-notes or aftertaste, typically bitter, metallic or liquorice off-notes.
  • Reb M also imparts lingering dryness and/or astringent mouthfeel sensory perceptions.
  • Reb M is able to impart an intense sweetness to a comestible product at low concentrations as compared to sucrose, it also exhibits a lower solubility in water as compared to other natural and artificial sweeteners typically used in the food and beverage industry. This lower water solubility of Reb M is a negative characteristic that limits its technical feasibility and use at an industrial scale.
  • a sweetness modifying composition comprising: one or more high-intensity sweetener(s) selected from the group consisting of steviol glycosides and/or mogrosides; and one or more low-intensity sweetener(s) selected from the group consisting of cellobiose, psicose, cyclamate and/or 11-O-mogroside V; wherein the sweetness modifying composition increases the sweetness of a sweetened composition by more than the sweetness of the sweetness modifying composition alone; and/or wherein the ratio of the one or more high-intensity sweetener(s) to the one or more low-potency sweetener(s) ranges from about 2:1 to about 12:1.

  • Astringency is defined by the American Society for Testing and Materials (ASTM, 2004) as the complex of sensations due to shrinking, drawing or puckering of the epithelium as a result of exposure to substances such as alums and tannins. It is believed that astringent molecules react with salivary proteins, especially proline-rich proteins and glycoproteins that act as natural lubricants such as mucins, causing them to precipitate and aggregate, and the resulting loss of lubricity leads to the rough, “sandpapery”, or dry sensation associated with astringency in the mouth. Astringency can be intrinsically present in certain consumables, such as tea, wine, yogurt and plant proteins.
  • Astringency can also be introduced into consumables as the result of adding certain ingredients such as vitamins, minerals, amino acids, proteins, peptides or antioxidants. While these ingredients might be employed as additives with the intention of improving the health and safety of food or for reasons of nourishment, they can also carry with them a perception of astringency and undesired mouthfeel properties.
  • Mouthfeel refers to the physical sensations experienced or felt in the mouth that are created by food and beverages, or compositions added to food or beverages. Mouthfeel may refer to textures that come into contact with the tongue, roof of the mouth, teeth, gums, or throat. Mouthfeel is considered to be distinct from taste/flavor, but is considered to have an equal or even greater impact on a person’s enjoyment or preference for certain foods over others.
  • Typical mouthfeel descriptors used to describe perceived sensations include acidity (metallic, citrusy, bright), density (close, airy), dryness (arid, scorched), graininess (particulate, powdery, dusty, grainy, chalky), gumminess (chewy, tough), hardness (crunchy, soft), heaviness (full, weighty), irritation (prickly, stinging), mouth coating (oily, buttery), roughness (abrasive, textured), slipperiness (slimy, stringy), smoothness (satiny, velvety), uniformity (even, uneven) and viscosity (full-bodied, light-bodied).
  • the sweetness characteristics may refer to the flavour profile (taste profile), which refers to the intensity of the flavour and perceptual attributes of a given compound.
  • flavour profile refers to the intensity of the flavour and perceptual attributes of a given compound.
  • Exemplary flavour attributes of sweetness are sweetness intensity, bitterness, black liquorice etc.
  • the sweetness characteristics may refer to the temporal profile, which refers to the changes in perception of sweetness over time. Every sweetener exhibits a characteristic appearance time (AT) and extinction time (ET). Most high-potency sweeteners, in contrast to carbohydrate sweeteners, display prolonged ET (lingering). Generally, the detected sucrose equivalence spikes to a maximal response level, then tapers off over time. The longer the taper, the greater the detected sweetness linger of a compound.

TECHNICAL FIELD
The present invention relates generally to the use of one or more low-potency sweetener(s) to improve one or more sweetness characteristics of one or more high- intensity sweetener(s). The present invention thus also relates to compositions comprising a mixture of at least one high-intensity sweetener and at least one low- potency sweetener. The present invention further relates to the use of a combination of at least one high-intensity sweetener and at least one low-potency sweetener as a sweetness modifier wh+en used in combination with at least one other sweetener and/or as a sweetener. The present invention further relates to the use of one or more mogroside(s) as a sweetness enhancer in sweetened compositions and said sweetened compositions. The present invention further relates to methods of making the sweeteners and compositions disclosed herein.
BACKGROUND
Sweetness in comestible products, that is products intended to be taken by mouth either for permanent ingestion or temporarily for expectoration, is often a desirable characteristic. Traditionally, sweetness has been provided by the addition of one or more sweeteners, particularly low-potency, nutritive sweeteners such as sucrose (table sugar), fructose, glucose, xylose, arabinose, rhamnose, sugar alcohols such as erythritol, xylitol, mannitol, sorbitol and inositol as well as sugar syrups such as high fructose corn syrup and starch syrup. These deliver considerable sweetness without any undesirable aftertaste. However, it is desirable to use a reduced amounts of these sweeteners to reduce the caloric value of the comestible product. It is therefore desirable to provide alternative sweeteners that can reduce the caloric value of the comestible product whilst maintaining the same or a similar sweetness taste.
High-intensity sweeteners (HIS) have been used for this purpose. High-intensity sweeteners may be natural or artificial and have a sweetness that can be several hundred times that of sucrose and thus can theoretically replace a much larger quantity of sugar in a composition. Examples of high-intensity sweeteners include sucralose, saccharin, aspartame, acesulfame potassium (AceK), neotame, advantame, sterviol glycosides, including stevioside, rebaudioside A, rebaudioside D or steviol glycoside mixture preparations with rebaudioside A and/or stevioside as predominant components. However, these substances generally have the drawback that they may impart undesirable off-tastes to comestible products, typically bitter, metallic or liquorice tastes, or an undesirable lingering sweetness.
Sucrose imparts an intense upfront sweetness that is short in time and decreases without any significant off-notes or aftertaste. Rebaudioside M (Reb M or reb M) has been used as an alternative sweetener to sucrose to reduce the caloric value of a comestible product. Reb M has a delayed and slight upfront sweetness as compared to sucrose, which transitions to an intense sweet impact followed by a quick decrease in sweetness and undesired lingering off-notes or aftertaste, typically bitter, metallic or liquorice off-notes. Reb M also imparts lingering dryness and/or astringent mouthfeel sensory perceptions.
Furthermore, while Reb M is able to impart an intense sweetness to a comestible product at low concentrations as compared to sucrose, it also exhibits a lower solubility in water as compared to other natural and artificial sweeteners typically used in the food and beverage industry. This lower water solubility of Reb M is a negative characteristic that limits its technical feasibility and use at an industrial scale.
It is therefore desirable to provide alternative and/or improved sweetness modifying composition and sweetened compositions to address one or more of these issues. SUMMARY

DETAILED DESCRIPTION
The present invention is based on the surprising finding that a combination of one or more high-intensity sweetener(s) (e.g. mogroside V) and one or more low-potency sweetener(s) (e.g. 11-O-mogroside V) can act synergistically with at least one other sweetener (e.g. sucrose) to obtain a composition having a sweetness that is greater than the sum of the sweetness of the individual sweeteners. The present invention is further based on the surprising finding that one or more low-potency sweetener(s) may offset one or more negative sweetness characteristics of one or more high-potency sweetener(s). For example, the combination of one or more high-intensity sweetener(s) (e.g. mogroside V) and one or more low-potency sweetener(s) (e.g. 11-O-mogroside V) may provide improved sweetness characteristics in a sweetened composition (i.e. a composition comprising at least one other sweetener such as sucrose in an amount above its sweetness recognition threshold and/or an amount equal to or greater than about 1.5 % (w/v) sucrose equivalence) compared to using the one or more high-intensity sweetener(s) alone. The sweetness characteristics may thus, for example, be closer to the sweetness characteristics of sucrose.
Thus, there is provided herein various compositions comprising one or more high-intensity sweetener(s) and one or more low-potency sweetener(s) as disclosed herein, particularly sweetened compositions comprising at least one sweetener in an amount above its sweetness recognition threshold and/or an amount equal to or greater than about 1.5 % (w/v) sucrose equivalence and one or more high-intensity sweetener and one or more low-potency sweetener(s). The sweetened compositions may also be referred to as comestible compositions. There is also provided herein various uses of one or more high-intensity sweetener(s) and one or more low-potency sweetener(s) as disclosed herein and methods of making the various compositions disclosed herein.
The present invention is further based on the surprising finding that mogrosides such as mogroside IV, siamenoside and neomogroside can act as sweetness enhancers (i.e. can increase the sweetness of a sweetened composition by more than the sweetness of the sweetness enhancer alone).
Thus, there is provided herein various compositions, in particular sweetened compositions, comprising one or more of mogroside IV, siamenoside and neomogroside.
Compositions
There is provided herein various compositions comprising at least one high-intensity sweetener and at least one low-potency sweetener. There is also provided herein compositions comprising one or more mogroside(s), for example one or more of mogroside IV, siamenoside and neomogroside. In certain embodiments, the compositions are comestible compositions. In certain embodiments, there is provided a sweetness modifying composition comprising, consisting essentially of or consisting of at least one high-intensity sweetener selected from the group consisting of steviol glycosides and/or mogrosides and at least one low-potency sweetener selected from the group consisting of cellobiose, psicose, cyclamate and/or 11-O-mogroside V. In certain embodiments, the sweetness modifying composition comprises, consists essentially of or consists of one high-intensity sweetener and one low-potency sweetener. The sweetness modifying composition may, for example, be a concentrate which may, for example, be diluted in a sweetened (e.g. comestible) composition to give the comestible composition a desired sweetness. The term “sweetened composition” refers to a composition comprising at least one sweetener present in an amount above its sweetness recognition threshold and/or in an amount having a sweetness equal to or greater than about 1.5 % (w/v) sucrose equivalence.
In certain embodiments, there is provided a sweetened composition (e.g. comestible composition) comprising one or more mogroside(s), for example one or more of mogroside IV, siamenoside and neomogroside. In certain embodiments, there is provided a sweetened composition (e.g. comestible composition) comprising at least one high-intensity sweetener and at least one low-potency sweetener. The combination of the high-intensity sweetener(s) and low-potency sweetener(s) may be referred to as a sweetness modifying composition. The one or more mogroside(s), for example the one or more of mogroside IV, siamenoside and neomogroside may also be referred to herein as a sweetness modifying composition. Thus, in certain embodiments, there is provided a sweetened composition comprising at least one sweetener present in an amount above its sweetness recognition threshold and/or in an amount having a sweetness equal to or greater than about 1.5 % (w/v) sucrose equivalence and a sweetness modifying composition comprising, consisting essentially of or consisting of at least one high-intensity sweetener and at least one low-potency sweetener. The sweetened composition may, for example, be a comestible composition.
The term “enhancing” when used in relation to a particular sweetness modifying composition refers to a synergistic sweetening effect when the sweetness modifying composition is used in combination with at least one other sweetener. The sweetness modifying composition increases the sweetness of a sweetened composition by more than the sweetness of the sweetness modifying composition alone. In other words, the sweetness of a composition comprising at least one sweetener and at least one sweetness modifying composition is greater than the sum of the sweetness of all the sweeteners in the composition. The sweetness modifying compositions described herein are used in sweetened (e.g. comestible) compositions in amounts that have no detectable sweetness or no taste recognised as sweet (below its sweetness recognition threshold). Typically, a sweetness modifying composition with a sweetness below 1.5 % (w/v) sucrose equivalence is accepted as being “not intrinsically sweet” by FEMA (Flavor & Extract Manufacturers Association). Sweetness modifiers may also be referred to as sweetness enhancers.
The sweetened composition comprising the sweetness modifying composition as disclosed herein and at least one sweetener in an amount above its sweetness recognition threshold and/or in an amount having a sweetness equal to or greater than about 1.5 % (w/v) sucrose equivalence may have a sweetness that is equal to or more than about 1.0 % (w/v) sucrose equivalence greater than the sweetness of the sweetened composition in the absence of the sweetness modifying composition. For example, the sweetened composition may have a sweetness that is equal to or more than about 1.1 % (w/v) or equal to or more than about 1.15 % (w/v) or equal to or more than about 1.2 % (w/v) or equal to or more than about 1.25 % (w/v) sucrose equivalence greater than the sweetness of the sweetened composition in the absence of the sweetness modifying composition. In other words, the sweetness modifying composition may increase the sweetness of a sweetened composition by equal to or more than about 1 % (w/v) or equal to or more than about 1.1 % (w/v) or equal to or more than about 1.15 % (w/v) or equal to or more than about 1.2 % (w/v) or equal to or more than about 1.25 % (w/v) sucrose equivalence. The comparative composition is identical to the said composition except that it does not include the said sweetness modifying composition.
The term “sucrose equivalence” refers to the equivalence in sweetness of a composition containing at least one non-sucrose sweetener to a reference sucrose solution. Typically, taste panellists are trained to detect sweetness of reference sucrose solutions containing between 1 % and 15 % sucrose (w/v). Other non-sucrose sweeteners may then be tasted at a series of dilutions to determine the concentration of the non-sucrose sweetener that is as sweet (i.e. isosweet) to a given sucrose reference. The term “isosweet” refers to compositions that have equivalent sweetness. Typically, the sweetness of a given composition is measured with reference to a solution of sucrose. See "A Systematic Study of Concentration-Response Relationships of Sweeteners," G.E. DuBois, D.E. Walters, S.S. Schiffman, Z.S. Warwick, B.J. Booth, S.D. Pecore, K. Gibes, B.T. Carr, and L.M. Brands, in Sweeteners: Discovery, Molecular Design and Chemoreception, D.E. Walters, F.T. Orthoefer, and G.E. DuBois, Eds., American Chemical Society, Washington, DC (1991), pp 261-276.
The combination of the one or more high-intensity sweetener(s) and the one or more low-potency sweetener(s) (e.g. the sweetness modifying composition) may, for example, have a sweetness less than about 1.5 % (w/v) sucrose equivalence. For example, the combination of the high-intensity sweetener(s) and the low-potency sweetener(s) (e.g. sweetness modifying composition) may have a sweetness equal to or less than about 1.45 % (w/v) sucrose equivalence or equal to or less than about 1.4 % (w/v) sucrose equivalence or equal to or less than about 1.35 % (w/v) sucrose equivalence or equal to or less than about 1.3 % (w/v) sucrose equivalence. For example, the combination of the high-intensity sweetener(s) and the low-potency sweetener(s) (e.g. sweetness modifying composition) may have a sweetness equal to or greater than about 1 % (w/v) sucrose equivalence or equal to or greater than about 1.1 % (w/v) sucrose equivalence or equal to or greater than about 1.15 % (w/v) sucrose equivalence or equal to or greater than about 1.2 % (w/v) sucrose equivalence or equal to or greater than about 1.25 % (w/v) sucrose equivalence or equal to or greater than about 1.3 % (w/v) sucrose equivalence.
The one or more mogroside(s), for example one or more sweetness enhancer(s) selected from mogroside IV, siamenoside and neomogroside may, for example, have a sweetness less than about 1.5 % (w/v) sucrose equivalence. For example, the one or more mogroside(s), for example one or more sweetness enhancer(s) selected from mogroside IV, siamenoside and neomogroside may have a sweetness equal to or less than about 1.45 % (w/v) sucrose equivalence or equal to or less than about 1.4 % (w/v) sucrose equivalence or equal to or less than about 1.35 % (w/v) sucrose equivalence or equal to or less than about 1.3 % (w/v) sucrose equivalence. For example, the one or more mogroside(s), for example one or more sweetness enhancer(s) selected from mogroside IV, siamenoside and neomogroside may have a sweetness equal to or greater than about 1 % (w/v) sucrose equivalence or equal to or greater than about 1.1 % (w/v) sucrose equivalence or equal to or greater than about 1.15 % (w/v) sucrose equivalence or equal to or greater than about 1.2 % (w/v) sucrose equivalence or equal to or greater than about 1.25 % (w/v) sucrose equivalence or equal to or greater than about 1.3 % (w/v) sucrose equivalence.
Each of the sweeteners and sweetness enhancers used in the compositions disclosed herein may be a natural or synthetic (artificial) sweetener. Examples of non-naturally occurring (i.e. synthetic) mogrosides are disclosed in WO 2017/075257, the contents of which are incorporated herein by reference. The term “natural sweetener” refers to sweeteners that are obtained from nature, including mixtures that may have been enzymatically treated (e.g. glycosylated) to form compounds not found in nature (this does not include purified compounds that have been enzymatically treated). For example, a modified extract having a mogrol glycoside distribution that is different (e.g. enhanced) from the naturally occurring mogrol glycoside distribution may be classed as natural. For example, a mixture of glucosylated steviol glycosides and/or glucosylated mogrosides may be classed as natural. Each of the sweeteners used in the compositions disclosed herein may be food-derived. A “food-derived” product refers to a product which is prepared under typical cooking conditions such as, for example, using temperatures similar to those used in cooking methods. In certain embodiments, the high-intensity sweetener and the low-potency sweetener used in the compositions disclosed herein (e.g. in the sweetness modifying composition disclosed herein) are both natural sweeteners. In certain embodiments, all of the sweeteners used in the compositions disclosed herein are natural.
The sweeteners disclosed herein may be used in pure or purified form and may be chemically synthesised, produced by biotechnological processes (e.g. fermentation) or isolated from a natural source (e.g. a botanical source including, without limitation, fruits, sugar cane, sugar beet).
The one or more mogroside(s), for example the one or more of mogroside IV, siamenoside and neomogroside may, for example, be at least 80 wt% pure. For example, the one or more mogroside(s), for example one or more of mogroside IV, siamenoside and neomogroside may be at least about 85 wt% or at least about 90 wt% or at least about 95 wt% or at least about 98 wt% or at least about 99 wt% pure. For example, the one or more mogroside(s), for example one or more of mogroside IV, siamenoside and neomogroside may be up to 100 wt% or up to 99 wt% pure.
The term “high-intensity sweetener” refers to compounds having a sweetness that is at least 100 times the sweetness of sucrose. In certain embodiments, the high-intensity sweetener has a sweetness that is at least about 120 or at least about 140 or at least about 150 or at least about 160 or at least about 180 or at least about 200 or at least about 220 or at least about 240 or at least about 250 or at least about 260 or at least about 280 or at least about 300 or at least about 320 or at least about 340 or at least about 350 or at least about 360 or at least about 380 or at least about 400 or at least about 420 or at least about 440 or at least about 450 times the sweetness of sucrose. The high-intensity sweetener may, for example, have a sweetness that is up to 1000 times the sweetness of sucrose. Although the high-intensity sweetener has a sweetness that is at least 100 times the sweetness of sucrose, in the context of its use in a sweetness modifying composition as described herein, they will be used in a sweetened composition in an amount that does not have any detectable sweetness or be recognised as sweet (amounts providing a sweetness less than 1.5 % (w/v) sucrose equivalence, which is accepted as being “not intrinsically sweet” by FEMA.
The one or more high-intensity sweetener(s) may, for example, be one or more steviol glycosides and/or one or more mogrosides. For example, the one or more high-intensity sweetener may be a mixture of steviol glycosides and mogrosides. For example, the one or more high-intensity sweeteners may be one or more steviol glycosides. For example, the one or more high-intensity sweetener(s) may be one or more mogrosides.

The proportion of the combination of the one or more high-intensity sweetener(s) and one or more low-potency sweetener(s) (e.g. sweetness modifying composition) or the one or more sweetness enhancer(s) selected from mogroside IV, siamenoside and neomogroside will depend on the nature of the composition and the degree and characteristics of the sweetness desired. The skilled person can readily ascertain the appropriate proportion in every case with only simple, non-inventive experimentation. The amounts and proportions disclosed herein are exemplary only and the flavourist may seek particular effects by working outside this range, and it should be regarded as an indication only.
The pH of the composition disclosed herein may be any pH that does not adversely affect the taste of the sweetener blend. For example, the pH may range from about 1.8 to about 8 or from about 2 to about 5. A person skilled in the art would be able to identify a suitable concentration of each sweetener to use depending on the pH of the composition.
The use of the one or more low-potency sweetener(s) with the one or more high- intensity sweetener(s) may, for example, improve one or more sweetness characteristics in a sweetened composition in comparison to the use of the one or more high-intensity sweetener(s) alone. Thus, the sweetened compositions disclosed herein may, for example, have one or more improved sweetness characteristics compared to the sweetened compositions in the absence of the one or more low-potency sweetener(s). The use of one or more sweetness enhancer(s) selected from mogroside IV, siamenoside and neomogroside may, for example, improve one or more sweetness characteristics of a sweetened composition in comparison to the use of a different sweetness enhancer such as Luo Han Guo extract in place of the one or more of mogroside IV, siamenoside and neomogroside.
The sweetened compositions disclosed herein may, for example, have one or more sweetness characteristics that are more similar to sucrose compared to the sweetened compositions in the absence of the one or more low-potency sweetener(s) or compared to the sweetened compositions comprising a different sweetness enhancer.
The sweetened compositions disclosed herein may, for example, have a weakened lingering sweet taste in compared to the sweetened compositions in the absence of the one or more low-potency sweetener(s) or compared to the sweetened compositions comprising a different sweetness enhancer. The sweetened compositions disclosed herein may, for example, have a weakened bitter taste and/or astringent taste and/or metallic taste and/or liquorice taste compared to the sweetened compositions in the absence of the one or more low-potency sweetener(s) or compared to the sweetened compositions comprising a different sweetness enhancer.
The sweetened compositions disclosed herein may, for example, have a strengthened sweetness impact compared to the sweetened compositions in the absence of the one or more low-potency sweetener(s) or compared to the sweetened compositions comprising a different sweetness enhancer.
The comparative sweetened composition is identical except that it does not include any of the one or more low-potency sweetener(s) or identical except that it comprises a different sweetness enhancer in place of the one or more mogroside(s), for example one or more of mogroside IV, siamenoside and neomogroside.

Astringency is defined by the American Society for Testing and Materials (ASTM, 2004) as the complex of sensations due to shrinking, drawing or puckering of the epithelium as a result of exposure to substances such as alums and tannins. It is believed that astringent molecules react with salivary proteins, especially proline-rich proteins and glycoproteins that act as natural lubricants such as mucins, causing them to precipitate and aggregate, and the resulting loss of lubricity leads to the rough, “sandpapery”, or dry sensation associated with astringency in the mouth. Astringency can be intrinsically present in certain consumables, such as tea, wine, yogurt and plant proteins. Astringency can also be introduced into consumables as the result of adding certain ingredients such as vitamins, minerals, amino acids, proteins, peptides or antioxidants. While these ingredients might be employed as additives with the intention of improving the health and safety of food or for reasons of nourishment, they can also carry with them a perception of astringency and undesired mouthfeel properties.
Mouthfeel (or “mouth feel”) refers to the physical sensations experienced or felt in the mouth that are created by food and beverages, or compositions added to food or beverages. Mouthfeel may refer to textures that come into contact with the tongue, roof of the mouth, teeth, gums, or throat. Mouthfeel is considered to be distinct from taste/flavor, but is considered to have an equal or even greater impact on a person’s enjoyment or preference for certain foods over others. Typical mouthfeel descriptors used to describe perceived sensations include acidity (metallic, citrusy, bright), density (close, airy), dryness (arid, scorched), graininess (particulate, powdery, dusty, grainy, chalky), gumminess (chewy, tough), hardness (crunchy, soft), heaviness (full, weighty), irritation (prickly, stinging), mouth coating (oily, buttery), roughness (abrasive, textured), slipperiness (slimy, stringy), smoothness (satiny, velvety), uniformity (even, uneven) and viscosity (full-bodied, light-bodied).
The sweetness characteristics may refer to the flavour profile (taste profile), which refers to the intensity of the flavour and perceptual attributes of a given compound. Exemplary flavour attributes of sweetness are sweetness intensity, bitterness, black liquorice etc.
The sweetness characteristics may refer to the temporal profile, which refers to the changes in perception of sweetness over time. Every sweetener exhibits a characteristic appearance time (AT) and extinction time (ET). Most high-potency sweeteners, in contrast to carbohydrate sweeteners, display prolonged ET (lingering). Generally, the detected sucrose equivalence spikes to a maximal response level, then tapers off over time. The longer the taper, the greater the detected sweetness linger of a compound.
In certain embodiments, the one or more low-potency sweetener(s) may be used to weaken the lingering sweet taste of the sweetened composition comprising one or more high-intensity sweetener(s). In other words, the low-potency sweetener may be used to decrease the extinction time (ET) of the sweetened composition comprising one or more high-intensity sweetener(s). This relates to the undesirable lingering of the sweetness taste in the mouth after the composition is initially ingested or expectorated. The lingering sweet taste may, for example, refer to the length of time that the sweetness taste remains after it is initially detected, how rapidly the intensity of the sweetness taste decreases or fades after it is initially detected and the intensity of the sweetness taste after it is initially detected. The one or more low-potency sweetener(s) may, for example, decrease the length of time that the sweetness taste remains after it is initially detected and/or increase the speed at which the sweetness taste decreases after it is initially detected and/or decrease the intensity of the sweetness taste after it is initially detected.
In certain embodiments, the one or more low-potency sweetener(s) may be used to weaken the bitter taste and/or astringent taste and/or metallic taste and/or liquorice taste of the sweetened composition comprising the one or more high-intensity sweetener(s). The term “liquorice” refers to a sweet taste of a compound.
In certain embodiments, the one or more low-potency sweetener(s) may be used to strengthen the sweetness impact of the sweetened composition comprising the one or more high-intensity sweetener(s). The sweetness impact relates to the length of time it takes before the sweetness is initially detected and the intensity at which the sweetness is initially detected. The one or more low-potency sweetener(s) may, for example, decrease the amount of time before the sweetness is initially detected and/or increase the intensity at which the sweetness is initially detected.
The degree of sweetness and other sweetness characteristics described herein may be evaluated by a tasting panel of trained experts, for example as described in the examples below.
Manufacturing Methods
There is further provided herein methods of making the compositions disclosed herein. The compositions may be in accordance with any embodiment disclosed herein.
The methods may comprise combining each component of a desired composition in the desired proportions and optionally mixing the components together. The components may be combined and mixed in any suitable order.
A person skilled in the art would identify a suitable method to make the composition (e.g. suitable order in which to combine or mix the components) depending on the nature of the composition and the degree and characteristics of the sweetness desired. The methods may, for example, comprise providing a desired base composition and adding the sweeteners thereto.
Each of the sweeteners disclosed herein may be made by a synthetic process or by a biological (e.g. enzymatic) process or a fermentation process or may be isolated from a natural source such as a plant or fruit.
The process may, for example, comprise contacting at least one mogrol precursor substrate with a mogroside pathway enzyme. The enzyme may, for example, be present in a cell lysate or may be present in a host cell (e.g. a recombinant host cell). The enzyme may, for example, be a UGT enzyme (UDP-glucuronosyltransferase).
For example, a mogroside compound may be made by the biosynthetic pathway disclosed in WO 2013/076577 or WO 2014/086842, the contents of which are incorporated herein by reference.
For example, mogroside V may be made by the biosynthetic pathway disclosed in Itkin et al., “The biosynthetic pathway of the nonsugar, high-intensity sweetener mogroside V from Siraitia grosvenorii’ , PNAS, 7 November 2016, E7619 - E7628 and WO 2016/038617, the contents of which are incorporated herein by reference.
For example, a mogroside compound may be made by modifying (e.g. redistributing glycoside content) another mogroside compound. For example, a mogroside compound may be made by redistributing glycoside content of another mogroside compound using acid or enzymes as disclosed in WO 2014/150127, the contents of which are incorporated herein by reference.
The process may, for example, comprise extracting one or more sweetener compounds from a natural source such as a plant or fruit. This may, for example, be followed by a purification step to yield a high-intensity sweetener, low-intensity sweetener or mixture of sweeteners (e.g. mixture of high-intensity sweeteners such as a mixture of mogrosides). The extract may, for example, have a relatively high content of mogroside V and/or 11 -O-mogroside V (e.g. at least about 30 wt% or at least about 40 wt%). This may, for example, involve fractioning, for example by flash chromatography. One or more mogroside compounds (e.g. mogroside V) may be obtained from Luo Han Guo ( Siraitia grosvenorii) fruit.
When a fermentation process is used to make the target product (e.g. target mogroside product), the target can be extracted from the aqueous fermentation reaction medium using an appropriate solvent (e.g., heptane) followed by fractional distillation. The chemical composition of each fraction can be measured quantitatively by GC/MS (gas chromatography mass spectrometry). Fractions can be blended to generate the desired mogroside compounds (e.g. mogroside V and 11-O-mogroside V) for use in flavour or other applications.
Verification of acceptability of the final blended product can be carried out by direct comparison to a reference mogroside flavouring product (for example, an existing natural flavouring commercial product obtained from a commercial supplier). EXAMPLES
Example 1
Methods
Luo Han Guo fruit extracts obtained from Blue California (Tomas, Rancho Santa Margarita, California) (extract 4), Azile LCC (Rolling Hills Est, California) (extracts 1 and 2) and Chr. Olesen Group (Gentofte, Denmark) (extract 3) were analysed to identify the compounds present in the extract.
Sample solutions of the extracts were prepared by dissolving 16.52 pg of the sample in 25.0 mL solvent (acetonitrile/water 20/80 v/v). From this solution 100 pL were transferred into a HPLC vial and 900 pL solvent was added (66.1 ppm solution). From the sample solution 10 pL was transferred to a HPLC vial and 990 pL solvent was added (6.61 ppm solution). Both the 66.1 and 6.61 ppm solutions were injected twice on the LC-MS.
Calibration (reference) solutions of mogroside V were made by dissolving 9.22 mg mogroside V (98.5 % mogroside V obtained from AAPIN chemicals Ltd., Oxfordshire, UK) in 10.0 mL solvent (acetonitrile/water 20/80 v/v). The stock solution was stored in the freezer and used to prepare solutions of mogroside V at various concentrations (0.11 ppm, 0.34 ppm, 1.02 ppm, 3.07 ppm and 9.22 ppm). These solutions were also injected twice on the LC-MS.
2 pL of each solution was injected on an Acquity C18 BEH 1.7 pm 150 x 2.1 mm column (Waters, Milford, Massachusetts, United States) at 40°C. Compounds were eluted using a mixture of acetonitrile and 0.1% formic acid in water starting at 20% acetonitrile going up to 50% acetonitrile in 14 minutes. The gradient was back on the starting values in 1 minute and stabilized for 5 minutes. The flow was set on 400 pL during the whole run.
Eluted compounds were detected using liquid chromatography mass spectrometry (LC/MS). The mass spectrometer was operating in ESI negative mode measuring 150 to 2000 Amu with a resolution of 70000. Gas flow rates were sheath 60, aux 20 and sweep 3. Capillary temperature and aux gas heater temperature were set on 380°C and 400°C respectively.
The % of each component in the extract was calculated using the following equation and calibrated against a curve of the various concentration calibration mogroside V (reference) solutions described above. ratio = % component area = component area in sample (average area from 2 injections)
V = sample solvent volume in litres d = sample dilution (from sample solution to vial) slope = slope from mogroside V calibration curve with b (intercept) = 0 SW= sample weight in mg
Results
Figure 1 shows a chromatogram of a Luo Han Guo extract (extract 2 of Table 1 below).
Table 1 shows the composition of four different Luo Han Guo extracts. Mogroside V is the mogroside having the highest concentration in all four extracts (about 45 wt% in extract 1).
Table 1.
Example 2
Methods A Luo Han Guo fruit extract obtained from Azile LCC (Rolling Hills Est, California) (extract 1 of Example 1 above) containing about 68 wt% mogrosides was fractionated by reverse phase (C-18) flash chromatography.
Compounds were eluted using a mixture of methanol (MeOH) in water starting at 30% MeOH followed by a linear gradient of 30-80% MeOH then finally the column was flushed with 80% MeOH. The solvents were introduced at the flow rate of 30ml/min throughout the separation procedure. Eluted compounds were visualized with a UV detector set at 210 nm and a coronal light scattering detector. The % of each component in the extract was calculated using the equation described in Example 1 above.
Collected fractions were pooled according to Table 2 below, and then freeze dried to powders. The powder corresponding to various pooled fractions as given in Table 2 below was dissolved in various concentrations on top of 5% sucrose. The taste of these samples was compared by three expert panellists (trained flavourists) to controls of 5% sucrose. Thus the sweetness enhancement effect of each fraction or pool of fractions exhibited in 5% sucrose was determined.
Results
The results are indicated in the table below. The whole extract was collected into 22 fractions. Fractions 1-10 contain no mogroside V.
Table 2.
Fraction 1-10 and 19-22 have an off-taste, which is the character of Luo Han Guo fruit, no sweet enhancement impact. The better sweetness enhancement effect was observed within fractions 12-17, which contains mainly mogrosides. When the fractions almost have pure mogroside V, the lingering, dirty fermented note is more noticeable, such as fractions 14 and 15. Thus, pure mogroside V has inherent lingering off-taste.
Fraction 12 was the cleanest sweet, but less upfront due to small percentage mogroside V. Fraction 13 has better sweet quality, but slightly higher astringency. 11- O-mogroside V and mogroside V are the two major mogrosides in those two fractions, but with different ratio (F12 mogroside V: 11-O-mogroside V is 4:9 and F13 mogroside V:11-0-mogroside V is 13:3).
Mogroside V was very sweet, judged to be 425 times sweeter than sucrose, while 11- O-mogroside V is rated as 84 times sweeter than sucrose.
Example 3
Methods
A Luo Han Guo fruit extract obtained from Azile LCC (Rolling Hills Est, California) (extract 1 of Example 1 above) containing about 68 wt% mogrosides was fractionated and the composition of each fraction determined by the chromatography method described above in relation to Example 1.
Each fraction was combined with a solution of 5 % sucrose and the taste of these samples was compared by three expert panelists (trained flavourists) to controls of 5% sucrose.
Results
Table 3 shows the chemical composition of fractions 11 to 20 of the extract. ble 3.
4
Table 4 shows the tasting results for fractions 12 to 15. The results are similar to the results obtained in Example 2.
Table 4.
Example 4
Mogroside V and 11-O-mogroside V were isolated from extracts of Luo Han Guo using Agilent 1100 preparative HPLC system with a Phenomenex Luna C18 (2) column (5 pm, 210 X 21.4 mm), and combined to form solutions of various concentrations.
These solutions were combined with a solution containing 5 % (w/v) sucrose and 0.03 % (w/v) citric acid to give test samples and evaluated by a sweet sensitive taste panel of five experts (trained flavourists).
The results are shown in Table 5 below.
Table 5.
It was surprisingly found that blending 11-O-mogroside V with mogroside V improves the sweet quality compared to mogroside V alone. 11-O-mogroside V on top of mogroside V helped to reduce sweetness lingering (weaken later sweetness taste) and reduce astringent and bitter aftertastes compared to mogroside V alone. Thus, the 11-O-mogroside V made the sweetness taste more similar to sugar than mogroside V alone (i.e. assists in providing a temporal profile that is closer to sugar). This enables the use of higher concentrations of mogroside V to obtain higher sweetness whilst eliminating the disadvantages associated with using higher concentrations of this sweetener (e.g. lingering, bitter and astringent aftertastes). This was surprising given that mogroside V is the most potent mogroside sweetener and 11-O-mogroside V is of much lower potency.
Example 5
A sweet sensitive taste panel ranked the sweetness of solutions of a mixture of sweeteners (“Mixture 1”) in relation to sucrose solutions at a range of concentrations to determine sucrose equivalence. Mixture 1 was a combination of fractions 11 to 18 of Example 2 and contained 8.16 wt% 11-O-mogroside V and 61.6 wt% mogroside V. The results are shown in Table 6 below.
Table 6.
The data demonstrates that mixture 1 has a sweetness below 1 % sucrose equivalence (as determined by seven panellists), which is accepted as “not intrinsically sweet” by FEMA. Therefore, mixture 1 is suitable for use as sweetness modifiers or blends at the indicated concentrations because it does not have any detectable sweetness at these levels. A concentration of mixture 1 having an iso-sweet threshold close to 1 % (35 ppm) was selected and added to 5 % (w/v) sucrose solutions. This solution was then ranked against 5, 6, 6.5 and 7 % (w/v) sucrose solutions. This was repeated for 45 ppm Luo Han Guo extract. The average score of each solution was determined. The results are shown in Table 7 below.
Table 7.
It was surprisingly found that mixture 1 and Luo Han Guo extract act as sweetness enhancers since the increase in sweetness of the 5 % (w/v) sucrose solution to which they were added was greater than the sweetness of the sweetener alone. The taste of various concentrations of mixture 1 was tested by an expert panel of three people (trained flavourists) in solutions containing 5 % sucrose and 0.03 % citric acid. The taste was compared to the Luo Han Guo extract used in Example 2 (obtained from Azile LCC (Rolling Hills Est, California) (extract 1 of Example 1 above) and containing about 68 wt% mogrosides) (combined with the same 5 % sucrose and 0.03 % citric acid solution). The results are shown in Table 8.
Table 8.
Overall, mixture 1 provides a better sweet quality (less baggage, sweeter) than the Luo Han Guo extract. Example 6
A sweet sensitive taste panel ranked the sweetness of solutions of various sweeteners (mogroside V, mogroside IV, siamenoside, neomogroside, 11-O-mogroside V) in relation to sucrose solutions at a range of concentrations to determine sucrose equivalence. The sweeteners were obtained using an Agilent 1100 preparative HPLC system with a Phenomenex Luna C18 (2) column (5 pm, 210 X 21.4 mm). The results are shown in Tables 9 to 13. Table 9.
Table 10. Table 11.
Table 12. Table 13.
The data demonstrates that mogroside V (25 ppm), mogroside IV (30 ppm), siamenoside (25 ppm), mogroside V (25 ppm) in combination with 11-O-mogroside V (3 ppm) and neomogroside (30 ppm) all have a sweetness below 1.5 % sucrose equivalence (as determined by seven panellists), which is accepted as “not intrinsically sweet” by FEMA. Therefore, these compounds and mixtures are suitable for use as sweetness modifiers at the indicated concentrations because they do not have any detectable sweetness at these levels.
Concentrations of the tested sweeteners were selected with an iso-sweet threshold close to 1 % and added to 5 % (w/v) sucrose solutions. These solutions were then ranked against 5, 6, 6.5 and 7 % (w/v) sucrose solutions. The average score of each solution was determined. The results are shown in Table14 below.
Table 14.
It was surprisingly found that mogroside V, siamenoside, neomogroside and mogroside V act as sweetness enhancers since the increase in sweetness of the 5 % (w/v) sucrose solution to which they were added was greater than the sweetness of the sweetener alone.
The taste of these sweeteners was tested by an expert panel of three people (trained flavourists) in solutions containing 5 % sucrose and 0.03 % citric acid. The taste was compared to the Luo Han Guo extract used in Example 2 (obtained from Azile LCC (Rolling Hills Est, California) (extract 1 of Example 1 above) and containing about 68 wt% mogrosides). Mogroside IV, siamenoside and neomogroside are all better than Luo Han Guo extract in terms of sweet quality when added to 5 % sucrose and 0.03 % citric acid. These 3 compounds provide a sugar like taste with less lingering sweet taste. Siamenoside was described as having “more sweet body, sweeter, rounder with a little more upfront and more round lasting sweet”. Mogroside IV was described as having “good and similar sweetness as mogroside V”. Neomogroside was described as having “sweetness, but slightly bitter aftertaste”. The results for mogroside V are shown in Table 15.
Table 15.
In general, the tasters agreed that 80% mogroside V does not have the same full round sweet profile as the Luo Han Guo extract. The 80% mogroside V is more acidic tasting when applied to a sugar/acid/water solution. Example 7
Methods Mogroside V, siamenoside, mogroside IV and neomogroside were obtained using an Agilent 1100 preparative HPLC system with a Phenomenex Luna C18 (2) column (5 pm, 210 X 21.4 mm)..
The mogroside V, siamenoside, mogroside IV and neomogroside were each added to a solution containing 5 % sucrose and 0.03 % citric acid in a concentration of
25 ppm (mogroside V), 25 ppm (siamenoside), 30 ppm (mogroside IV) and
30 ppm (neomogroside) respectively.
These test solutions were tasted by an expert panel of seven people. For various aspects of sweet taste (upfront sweet, overall sweet, lingering sweet, astringent, volatile off-taste), each panellist scored the test solutions in comparison to the base solution (solution of 5 % sucrose and 0.03 % citric acid).
A score of 0 indicated that the taste aspect was the same, 1 indicates slightly higher, 2 indicates higher, 3 indicates much higher, -1 indicates slightly lower, -2 indicates lower and -3 indicates much lower. The average score for each test solution for each taste aspect was calculated. The results are shown in Table 16 below.
Table 16. Example 8
As shown above, siamenoside, neomogroside and mogroside IV all have similar or better sweet taste quality on top of 5 % sucrose and 0.03 % citric acid compared to mogroside V. Therefore, the taste of 11-O-mogroside V with each of these mogrosides is evaluated as shown in Table 17.
Table 17. Example 9
The taste of mogroside V with and without 11-O-mogroside V in various milk or yoghurt bases is evaluated as shown in Table 18. The iso-sweet threshold for mogroside V in milk and yoghurt is also evaluated.
A milk base (2% fat) includes 2% fat milk and 5 % sucrose. A non-fat yoghurt base includes plain non-fat yoghurt and 5 % sucrose. A full fat yoghurt base includes plain full fat yoghurt and 5 % sucrose. A higher dose level is used for milk and yoghurt compositions due to the fat, protein and other ingredients. Luo Han Guo extract is used at 75 ppm for these applications.

The identification of new minor cucurbitane glycosides from Siraitia grosvenorii Introduction
Siraitia grosvenorii (Swingle) C. Jeffrey ex Lu et Z. Y. Zhang is a herbaceous perennial vine of Cucurbitaceae family endemic to southern China and northern Thailand. The fruit of S. grosvenorii, commonly known as ‘luo han guo’ has been used for traditional medicine in China for centuries as a treatment of respiratory infection, bronchitis, gastritis, constipation etc. Modern pharmacological research have confirmed that S. grosvenorii extracts or its components possess variety of bioactivities, such as antibacterial, anti-inflammation, anti-diabetic, anti-cancer, and immunostimulatory [1], Luo Han Guo has been used as a sweetener in food and beverages in China. It is now one of the best known natural high intensity sweeteners throughout the world. Since cucurbitane glycoside mogroside V has been discovered as the sweet principle of S. grosvenorii, more than 40 cucurbitane triterpenoids have been reported from S. grosvenorii so far [1-4], Food and flavor industry researchers have been actively discovering and adding more new compounds into the mogroside pool in order to find new mogrosides with better sweet performance [5-7], New molecules under known natural sweetener categories with better sweet performance have been a sought-after for food and flavor industries. The commercialization of rebaubioside M (also known as rebaubioside X) is a good example. Even it is a minor natural product from Stevia (less than 0.1%) discovered in 2010, rebaubioside M quickly progressed into commercialization stage thanks to cost reduction by technology development in plant biology, molecular biology and enzyme engineering [8, 9], Rebaudioside M received Letter of No Objection concerning its Generally Recognized as Safe (GRAS) status from US FDA in 2013, 2014 and 2017 (GRN No. 473, 512 and 667) [10-12],
We have been conducting investigations to seek the best performance mogrosides or their combinations by using commercial Luo Han Guo extracts [13], Herein, we report two new minor cucurbitane glycosides from S. grosvenorii and emphasize our new oligosaccharide elucidation strategy based on HSQC-TOCSY experiments with different mixing times. Materials and Methods
General experimental procedures
Optical rotations were measure with a Rudolph Autopol IV polarimeter. The NMR spectra were recorded on Bruker DRX Avance 300 or 500 spectrometers. Chemical shifts are given in δ (ppm) referring to the residual solvent peak. Low pressure chromatography was performed on Biotage Flash System SP1. Preparative HPLC was performed on an Agilent 1100 preparative HPLC system with a Phenomenex Lunar C18(2) column (5 μm, 210 x 21.4 mm) or a TSKgel Amide-80 (5 pm, 300 x 21.5 mm) (Tosoh Bioscience LLC). Analytical HPLC was performed on an Agilent 1100 analytical HPLC system equipped with ESA Corona CAD detector. LC-MS was performed using Waters G-Tof micro mass spectrometer coupled with Waters 2795 separation module.
Plant material The Luo Han Guo extract (commercial name Swingle, -60% mogrosides) was purchased from Blue California Co., Ltd.
Instrumentation
Chromatographic conditions: The chromatography was performed on a Waters Acquity H UPLC. Separation was carried out at 25 C using a 1.0 *100 mm, Acquity UPLC HSS T3 column (Waters), with a particle size of 1.8 mm, equipped with a 0.2 mm prefilter. Solvent A was water and solvent B was acetonitrile, both solvents contained 0.1% formic acid. Injection volume was set to 10 pi. The chromatography flow rate was 200 pl/min. Sample was eluted from the LC column using the following linear gradient (curve number 6): 0-40min: 90% A-30% A; 40-45 min: 30-10% A; 45-50 min: 10% A; 50-51 min 10%-90% A, 51-55 min 90% A for re-equilibration.
Mass spectrometry
The U-HPLC system was coupled to a hybrid quadrupole orthogonal time-of-f light (TOF) mass spectrometer (SYNAPT G2 HDMS, Waters MS Technologies, Manchester, UK). The mass spectrometer was operated in the positive electrospray ionization mode (ESI+). The sample cone voltage 40, capillary voltage 0.7 kv, source temperature 40 °C, desolvation temperature 450 °C, desolvation gas flow 800 L/h, and cone gas flow 50 L/h were optimized. Leucine enkephalin was used as the lock mass [M+H]' at m/ z 556.2771. Sodium formate solution was used for external instrument calibration.
Purification 3 g Luo Han Guo extract was dissolved in 15 mL water and loaded onto a preequilibrated C-18 Snap cartridge (KP-C18-HS, 120 g, 132 mL column volume). The gradient system (A: water; B: methanol) used was: 30% 2 CV, 30%~80% 10 CV, 80%~100% 2 CV, 100% 2 CV. The flow rate was 30 mL/min. Fractions were collected for 27 mL per tube. Four loading of total 12 g Luo Han Guo was fractionated. All the fractions were analyzed by analytical HPLC to locate the fractions with the target mogrosides (isocratic mobile phase: 24% acetonitrile in water. Column: Luna C18 5pm 4.6x150mm). Fractions 36-38 with iso-mogroside VI and 11-epi-mogroside V were combined to evaporate solvents. Further preparative HPLC purification of fractions 36- 38 afforded iso-mogroside VI (1, 22 mg) and 11-epi-mogroside V (2, 17 mg) (24% acetonitrile in water, 10 mL/min, retention time 13.1 min and 14.3 min, respectively). 11-oxo-mogroside V (4) and neomogroside (3) were mainly in flash fractions 39-40 with 11-oxo-mogroside V as the major component. On reverse phase C-18 preparative HPLC, neomogroside appeared as a tail shoulder of 11-oxo-mogroside (24% acetonitrile in water, 10 mL/min, retention time 17.0 min and 18.0 min, respectively). Collection of the peak front gave 105 mg of the compound 11-oxo-mogroside V (4). Further purification of the shoulder neomogroside (3, 15 mg) was achieved by preparative HPLC on TSKgel Amide-80 (65% acetonitrile in water, 20 mL/min, rt 15.5 min). iso-mogroside VI (l);White amorphous powder; [a]20 D -8.2 (c 0.12, MeOH); For 1H NMR and 13C spectroscopic data, see Tables 1;-HRESIMS: m/z 1449.7075 [M+H] " (calcd. for C66H113034, 1447.7113, D2.6 ppm). epi-mogroside V (2) .White amorphous powder; [a]20 D+4.5 (c 0.13, MeOH); For 1H NMR and 13C spectroscopic data, see Tables 1; HRESIMS: m/z 1287.6558 [M+H]" (calcd. for C60H103O29, 1287.6585, D2.1 ppm).
Acid hydrolysis and determination of absolute configuration of sugars
Compounds 1 (1.2 mg) or 2 (1.8 mg) were incubated in 1 mL 1 M HCI at 80 °C for 3 hrs. After hydrolysis, the solution was extracted with EtOAc (1 mL *3). The remaining aqueous solutions were evaporated by blowing nitrogen gas and freezing dried. The absolute configuration of the sugar in the residue was determined by GC-MS analysis of its O-silylated derivative and comparing with the derivatives of D-glucose and L- glucose standards. Briefly, the sugar residues, D-glucose (2 mg) or L-glucose (2 mg) were dissolved in pyridine (0.5 mL). 0.1 M L-cysteine methyl ester hydrochloride (Aldrich, Milwaukee, Wl) in pyridine (0.5 ml_) was added into the solution. The mixture was kept at 60 °C for 2 h and dried by blowing nitrogen gas. The residue was added with 1-trimethylsilylimidazole (Fluka, Buchs, Switzerland) (0.5 ml_) and incubated under 60 °C for 1 h. The mixture was partitioned by adding n- hexane and water (1.0 ml_ each). The n- hexane extract was analyzed by GC-MS under the following conditions: capillary column HP-5MS (30 m c 0.25 mm c 0.25 μm, Agilent); column temperature, 180 to 230 °C at a ramp of 5 °C/min ; injection temperature, 250 °C; carrier, He gas; split ratio, 20:1. The O-silylated derivatives of D-glucose and L-glucose showed retention time at 16.02 and 16.39 min, respectively. By comparing the retention time and co-chromatography, the sugar residues after acid hydrolysis of 1 and 2 were determined to be D-glucose.
Reduction of 11-oxo-mogroside V with NaBH4
25 mg of 11-oxo-mogroside V (4) was dissolved in 50% dioxane and added with 20 mg NaBH4 and heated at 50 °C for 3 days. The reaction mixture was periodically analyzed by HPLC to monitor the reaction progress. After the reaction, the mixture was acidified by acetate acid and concentrated to dryness by blowing nitrogen gas. The residue was re-dissolved in water and passed through a pre-equilibrated C-18 SPE column. The methanol eluents from SPE column were concentrated. The residue was then separated by semi-preparative HPLC. The two reduced products had same retention time and molecular weight as the isolated mogroside V and 11-epi-mogroside V by LC-MS analysis and co-chromatography on analytical HPLC. The 1-D and 2-D NMR data also confirmed that the structures of the two reduced products were mogroside V and 11-epi-mogroside V.
Results and Discussion
Isolation and elucidation of iso-mogroside VI (1) and 11-epi-mogroside V (2)
During the course of investigating a commercial Luo Han Guo extracts with 60% mogrosides by LC-MS, several mogrosides with six or five sugar moieties in the extracts attracted our attention (Figure 2 and 3). Since there were little report on the sweet properties of mogroside V and VI isomers, we decided to purify and identify these isomers for our evaluation. The concentrations of 1 , 2, 3 and 4 in the extracts were estimated to be 0.8%, 0.5%, 0.6%, 4.9%, respectively, according to the universal Corona detector. After fractionated on flash chromatography system and followed by preparative HPLC purification, the four targeted mogrosides 1-4 were purified and determined to be iso-mogroside VI (1), 11-epi-mogroside V (2), neomogroside (3), 11- oxo-mogroside V(4).
The molecular formula of 1 was deduced as C66H112034 by its HR-ESI-MS spectral data ([M-H] ' m/z, 1447.6957, calcd. for C66H11 1034, 1447.6957). The NMR spectral data of 1 suggested the structure of a hexasaccharide triterpenoid saponin: 30 of the 66 carbons were assigned to the triterpenoid aglycone, and 36 of 66 to six hexose moieties. The 13C and 1H NMR spectra of 1 showed the signals of seven singlet tertiary methyls, a doublet secondary methyl, and an olefinic methine (Table 19), which suggested a typical (24R)-cucurbit-5-ene^,11a,24,25-tetraol mogrol aglycone. The mogrol aglycone of 1 was further confirmed by extensive analysis of its 1H, 13C, and 2D (COSY, TOCSY, HSQC and NOESY) NMR data, as well as comparison with NMR data of mogroside V standard. Table 19. 1H NMR and 13C NMR spectroscopic data for iso-mogroside VI and 11-ep/- mogroside V (1H 300 MHz and 13C 75 MHz in pyridine-cfs^O 10:1) GC-MS analysis of water-soluble acid hydrolysis products of 1 showed that D-glucose was the only monosaccharide in the structure of 1. The HSQC spectra clearly displayed the anomeric cross-peaks of six glucosyls: Glc-I (<δC 106.8 and <δH 4.73), Glc- II ( <σC 105.1 and <δH 5.10), Glc-lll (<δC 103.7 and <δH 4.85), Glc-IV (<δC 104.6 and <δH 4.78), Glc-V ( <δC 104.7 and <δH 5.43), Glc-VI ( <δC 104.8 and <δH 5.03). The stereochemistry of all the six glucopyranosyls were determined to be b configuration from their anomeric proton coupling constants 3Jm, H2· From HSQC-TOCSY experiment (hsqcgpmlph) with 100 ms mixing time, the glucopranosyl carbon signals can be divided into six groups (Figure 4). The oligosaccharide elucidation was started from the glucopyranosyl connected at C-3 of the cucurbitane aglycone. Glc-I was determined to link with aglycone C-3 according to the HMBC correlation of its anomeric proton (<δH 4.73, d, J = 7.9 Hz) with aglycone C-3 (<δC 87.6) and the NOESY correlation of Glc-I H-1 and aglycone H-3. The 13C signals of Glc-I ( <δC 75.1 , 77.8, 71.4, 77.2, 70.1) as determined by HSQC-TOCSY missed a typical C-6 carbon signal at around <δC 62. The downfield shift of Glc-I C-6 (<δC 70.1) indicated glycosylation at this position. By comparing HSQC- TOCSY spectra (hsqcgpmlph) with increased mixing time from 10, 30, 60, and 100 ms, the magnetization transfer relay can be observed gradually extending from C-2 to C-6 (Figure 4). As shown in Figure 4, HSQC-TOCSY under 10 ms mixing time displayed the correlation of glucopyranosyl H-1 and C-2. Under 30 ms mixing time, the correlation of H-1 and C-3 appeared in addition to H-1 and C-2 correlation. Under 60 ms, the carbon chain as indicated by the HSQC-TOCSY correlation extend to C-4. The full HSQC-TOCSY correlation of H-1 with C-2 to C-6 can be observed under 100 ms. Therefore, signals of C-2 to C-6 can be unambiguously assigned. The linkage of Glc-I I to Glc-I was established by the HMBC correlation of anomeric Glc-I I H-1 (<δH 5.10, d, J= 7.8 Hz) to Glc-I C-6 (<δC 70.1). The 13C signals of Glc-ll (<δC 75.0, 77.8, 71.5, 78.0, 62.5) suggested no glycosylation on Glc-ll. As a result, the sugar chain on aglycone C- 3 was furnished as 3-0-(B-D-glucopyranosyl(1®6)-B-D-glucopyranosyl.
HMBC correlation of anomeric proton (<δH 4.85, d, J= 7.5 Hz) to aglycone carbon signal (<δC 92.3) indicated the connection of Glc-lll H-1 to aglycone C-24. The 13C pattern of Glc-lll (<δC 81.6, 78.3, 71.4, 76.4, 70.0) suggested C-2 and C-6 glycosylation shifts. Analysis of HSQC-TOCSY with 10, 30, 60, and 100 ms mixing time resulted in the sequential assignment and confirmation of C-2 and C-6 downfield shifts. Glc-IV was determined to connect to C-6 of Glc-lll as from its H-1 (<δH 4.78, d, J= 7.5 Hz) HMBC correlation with C-6 of Glc-lll (<δC 70.0). Glc-IV was a regular terminal glucopyranosyl without any substitution ( <δC 74.5, 77.7, 71.2, 78.2, 62.4). The linkage of Glc-V to C-2 of Glc-lll was established by HMBC correlation of anomeric Glc-V H-1 (<δH 5.43, d, J= 7.8 Hz) to Glc-lll C-2 (<δC 81.6). The relatively down-field shift of Glc-V H-1 (¾ 5.43) was consistent with previous reports with similar structure. The 13C chemical shift of C-4 normally at <δC 70-71 was missing in the Glc-V signal set (<δC 104.7, 75.4, 76.4, 82.0, 76.5, 62.6), which suggested glycosylation at C-4. By observing the C-2 to C-6 relay from HSQC-TOCSY with 10, 30, 60 and 100 ms mixing time, <δC 82.0 was clearly assigned to C-4 of Glc-V (Figure 4). HMBC cross-peak between C-4 of Glc-V ( <δC 82.0) and H-1 of Glc-VI (<δH 5.03, d, J=7.7 Hz) further confirmed that Glc-VI linked to Glc-V at this position. Glc-VI was a terminal glucopyranosyl without further sugar branch. Based upon the above evidences, the structure of iso-mogroside (1) was assigned as 3-O-b- D-glucopyranosyl(1®6)-B-D-glucopyranosyl-mogrol-24-0-B-D-glucopyranosyl-(1®6- [B-D-glucopyranosyl-(1®4)-B-D-glucopyranosyl-(1®2)]-B-D-glucopyranosyl.
Compound 2 was assigned a molecular formula of C6OHI02029 from its HR-ESI-MS data ([M-H] ” m/z, 1285.6429). The NMR data of the oligosaccharide portion of 2 were superimposable with those of mogroside V. Detailed 2-D NMR experiments including HSQC, HMBC, NOESY, COSY and HSQC-TOCSY confirmed that 2 had the same sugar moieties as mogroside V. Attentions were then turned onto the aglycone NMR data. The HMBC correlation between C-11 and H3-19 revealed significant upfield shift of C-11 (<δC 72.5) as compared with mogroside V (<δC 77.8). Further assignment of aglycone data by 2-D NMR experiments showed that major 13C chemical shift changes occurred on C-8, C-10 and C-12 when comparing with the data of mogroside V (Table 19). This suggested b-OH instead of a-OH at C-11. The b-OH stereo structure of 2 was further established by NOE correlations between H-8 and H3-18, 19; H-10 and H3-28, H3-30; H-11 and H3-30; H-17 and H3-30. There were one natural 11-b-OH cucurbitane and one semi-synthetic 11-b-OH cucurbitane reported before [14, 15], The 13C NMR data of compound 2 aglycone had a good match with the data of the semi-synthetic 11- b-OH cucurbitane glycoside, which was recorded in pyridine-c/6 [14]. The 13C NMR data of natural 11-b-OH cucurbitane by Matsuda et al was obtained in methanol-d4 and were quite different in terms of chemical shifts at C-11 , C-8, C-10 and C-12 [15], To further confirm the 11-b-OH structure of 2, semi-synthesis of 2 was carried out by chemical reduction of 11-oxo-mogroside V (4) to the 11-b-OH and 11-a-OH isomers of mogroside V. By LC-MS, HPLC co-chromatography and NMR data analysis, the semisynthetic 11-epi-mogroside V was determined to be identical to the isolated 11-epi- mogroside V. Therefore, the structure of 11-epi-mogroside V (2) was elucidated as 3- 0-B-D-glucopyranosyl(1®6)-B-D-glucopyranosyl-11B-OH-mogrol-24-0-B-D- glucopyranosyl-(1 2)-[β-D-glucopyranosyl-(1→2)-[β-D-glucopyranosyl. To our best of knowledge, this is the first report of natural mogroside with a 11-b hydroxyl group.
HSQC-TOCSY with different mixing time for oligosaccharide chain elucidation.
Gheysen et al investigated TOCSY experiments with different mixing time and concluded 100 ms as the optimal spin lock time to discriminate D-glucose, D-galactose and D-mannose [16] Through their results, we noticed that the spin lock time could significantly affect the magnetization transfer efficiency of H-1 of D-glucose. The correlation between H-1 and H-2 through H-6 gradually extended to H-6 as the spin lock time increased. Inspired from their investigation, we hypothesized that by increasing spin lock time of HSQC-TOCSY, we should be able to see that the correlations of glucose H-1 with C-2 to C-6 gradually extend from C-2 to C-6 as the chain of the magnetization transfer extends. HSQC-TOCSY with increasing spin lock time should tell the carbon sequence information, which would be very useful for oligosaccharide elucidation and assignment. Figure 4 showed HSQC-TOCSY (hsqcgpmlph) of iso-mogroside VI with 10, 30, 60 and 100 ms mixing time. The cross peaks in Figure 4 were quantified by their integrals and compared in Figure 5. The peak intensity (as presented by the integrals) could be an indication of their distance from H-1 in some cases. For example, all the C-3 peaks were significantly weaker than C-2 peaks under 30 ms mixing time experiments. However, under 60 ms C-3 peaks become bigger than C-2 peaks. To ensure correct elucidation, the carbon sequence should be determined through the overview of all the HSQC-TOCSY spectra with different mixing time, not just by the peak intensity under one mixing time.
Traditionally, NMR elucidation and assignment of sugar chain of saponins start from the sugar linked to aglycone. By HMBC or NOESY, the well-resolved anomeric H-1 and C-1 signals can be identified. Then through COSY correlations and matching 3J (H,H) coupling constants, the proton signals of the monosaccharide can be assigned. Since a large coupling constant (>7 Hz) typically indicate two neighboring axial C-H bonds and small coupling constant (<4 Hz) for an axial-equatorial or equatorial-equatorial C-H bond, the type of monosaccharide can be determined. NOE correlations are useful for confirmation of the stereochemistry of axial-axial, axial-equatorial or equatorial- equatorial relations. The carbon signals of the saccharide (C-2 to C-6) are assigned according to HSQC or HMQC. The chemical shifts of the carbon signals as determined by HSQC/HMQC are very important information to confirm the monosaccharide type since the pattern of C-1 to C-6 chemical shifts for different type of monosaccharides is characteristic and consistent. Through the observation of carbon chemical shifts changes, the glycosylation position on the sugar chain can be identified and further confirmed by HMBC correlation. In summary, traditional way to elucidate saponin sugar is: HMBC ® C-1 , H-1 ® COSY ® H-2 to H-6 ® HSQC/HMQC ® C-2 to C-6, then assisted and confirmed by coupling constant analysis and NOESY experiment.
1H-1H TOCSY (Total Correlated Spectroscopy also known as HOHAHA - Homonuclear Hartmann Hahn) experiment could be a big help to divide the complicated sugar proton signals into groups. The transfer of magnetization during the TOCSY spin lock from the anomeric H-1 to the end of the furanose or pyranose ring will depend on the magnitude of the intervening 3J (H,H) scalar coupling constants. Neighboring axial-axial protons with large coupling constant (>7 Hz) allow a fast transfer of magnetization, whereas axial-equatorial or equatorial-equatorial with small coupling constant (<4 Hz) will considerably reduce transfer efficiency. Therefore, TOCSY experiment not only can be used to group proton signals into spin systems, but also provide the stereochemistry information of the saccharide. For example, we should be able to see the magnetization relay of glucose through H-1 to H-6 with the right mixing time. For galactose, there is no magnetization relay over H-4 even with 200 ms mixing time.
However, for the case of mogrosides with five or six sets of glucopyranosyl signals, using COSY and TOCSY to connect H-1 to H-6 can be quite tricky. The proton signals of the mogroside glucopyranosyls have very similar chemical shifts and appear crowded in a small range from <δH 3.8 to 4.5. It is hard to make clear COSY connections through such poorly-resolved proton signals. The glucopyranosyl carbon signals are also very close and the HSQC cross-peaks heavily overlap to each other , which make the elucidation and assignment even more difficult.
Previously, HSQC-TOCSY have been applied in the structure elucidation and assignment of saponins by grouping carbon signals in each spin system together [17, 18], Through our investigation, we demonstrated for the first time that the signal sequence within the glucopyranosyl carbon group can be identified by applying different mixing time in HSQC-TOCSY experiments.
Figure 6 summarized the new HSQC-TOCSY based strategy to elucidate the glucopyranosyl oligosaccharide chain of mogrosides as follows: In Step 1 , Heteronuclear multiple bond correlation spectroscopy (HMBC) was used to determine anormeric C-1 and H-1 of the sugar. Start from the sugar link to aglycone. In Step 2, HSQC-TOCSY was used with 100ms mixing time to determine the whole group of C-2 to C-6. HSQC-COSY or HSQC-TOCSY (d9=10 ms) to assign C-2. HSQC-TOCSY (d9=30 ms) to assign C-3. HSQC-TOCSY (d9=60 ms) to assign C-4. HSQC-TOCSY (d9=100 ms) to assign C-5 and C-6. In Step 3, if a C-2 downshift from ~d75 to ~d81, C-4 downshift from ~d71 to ~d81 or C-6 downshift from ~d62 to ~69 is observed, check HMBC for glycosylation at these positions.** If a C-2 downshift from ~d75 to ~dd1, C- 4 downshift from ~d71 to ~dd1 or C-6 downshift from ~d62 to ~69, check HMBC for glycosylation at these positions.**. 1-D NMR data such as 1H coupling constants and 13C carbon signal pattern and 2-D NMR experiments such as NOESY, HMBC, TOCSY, COSY and HSQC could assist the process and confirm the results. The new HSQC- TOCSY based strategy may provide a simple, fast and unambiguous way for elucidation and assignment of glucopyranosyl chains of any new or known mogrosides. The strategy can also be adapted for elucidation and assignment of other monosaccharides and oligosaccharides.

Compound 3 was determined to be neomogroside by extensive 1-D and 2-D NMR analysis, as well as comparison with literature data [19], For the oligosaccharide chain elucidation of 3, signals were assigned by HSQC-TOCSY and TOCSY experiments with different mixing time at 10, 30, 60, 100 ms. The linkage of the six saccharides were made by their NOESY and HMBC correlations. The oligosaccharide chain on C-3 of aglycone can be clearly assigned as B-D-glucopyranosyl-(1®2)-B-D-glucopyranosyl- (1®6)-B-D-glucopyranosyl. The glucopyranosyl on C-24 of aglycone was branched with a B-D-glucopyranosyl-(1®2) and a B-D-glucopyranosyl-(1®6).
Neomogroside was firstly discovered from S. grosvenorii and described by Si et al. [19], Searching neomogroside in Scifinder returned the CAS number 169307-15-1. However, the incorrect structure of neomogroside was given in Scifinder even though the literature referred by Scifinder was the 1996 article by Si et al. The incorrect structure of 189307-15-1 was given as 3-0-B-D-glucopyranosyl-(1®2) -[b-D- glucopyranosyl-(1®6)]-B-D-glucopyranosyl-mogrol-24-0-B-D-glucopyranosyl-(1®6)- [B-D-glucopyranosyl-(1®2)]-B-D-glucopyranosyl (structure of 6 in Figure 2) in Scifinder. The report of neomogroside by Si et al was written in Chinese and published in a Chinese journal in 1996. The accessibility and misunderstanding of this article might lead to the incorrect structure in Scifinder.
In Scifinder, neomogroside and mogroside VI had the same CAS number 189307-15-1 and same structure. Takemoto et al firstly reported mogroside VI from S. grosvenorii [2], But it only referred a pure mogroside with a molecular formula of C66H112034 and no structure was determined [2], Prakash et al. reported the structure and NMR data of mogroside VI as a known compound in their article published in 2011 [6], In their article, the structure of mogroside VI was assigned as the structure of 6 in Figure 2. Prakash mentioned that the structure elucidation of mogroside VI was made by NMR analysis and also by comparing with the literature values. However, no citation was given for the literature values.
For known compounds, comparison of NMR data with literature data could be useful for structure determination. However, the complexity of mogroside NMR data makes it difficult to determine the structure mainly by comparison of NMR data with literature data. 1H NMR data of known mogrosides in different reports showed variations due to different NMR solvents used (the ratio of pyridine and D20 could cause signal shifts) or simply incorrect assignments.
Even though 13C NMR data are quite consistent and have better resolution than 1H NMR data, structure determination of oligosaccharide chain of known mogrosides cannot be relied on directly comparing 13C NMR data with literature data. Considering the case of neomogroside, if the Glu-VI glucopyranosyl-(1®2) branched on Glu-I, Glu- II, Glu-lll, Glu-IV, or GluV, the five isomers may have very similar 13C NMR data. Rather than comparing 13C NMR data with literature data, extensive 2-D NMR analysis should be carefully done before the oligosaccharide chain of mogrosides are unambiguously determined. Example 11
Sweet intensity of iso-mogroside VI and 11-epi-mogroside V
Methods 10 mg iso-mogroside VI (Figure 7) was dissolved in 31 mL water to make 100 ppm iso- mogroside VI solution. The working solution of 11-epi-mogroside V (Figure 8) was 374 ppm (9.34 mg 11-epi-mogroside V in 25 mL water). A series of standard sucrose solutions were prepared (0.50, 0.75, 1.00, 1.25, 1.50%) as sweetness references. Results
Four sweet sensitive panelists evaluated 100 ppm iso-mogroside VI and 374 ppm 11- epi-mogroside V and the sucrose standards, and were asked to give sweet equivalence concentrations to sucrose. The mean sweet equivalence concentrations of each compound were used to calculate the iso-sweet potency. The iso-sweet potency values of iso-mogroside VI and 11-epi-mogroside V were determined as 91 and 35 times of sweetness of sucrose, respectively (100 ppm iso-mogroside VI sweet equivalent to 0.91% sucrose; 374 ppm 11-epi-mogroside V sweet equivalent to 1.31% sucrose). Example 12
Methods
Iso-Mogroside VI and 11-epi-mogroside V were obtained as described in Example 10. The iso-Mogroside VI and 11-epi-mogroside V were each added to a solution containing 5 % sucrose and 0.03 % citric acid in a concentration of 25 ppm. These test solutions were tasted by an expert panel of seven people. For various aspects of sweet taste (overall sweet, upfront sweet, lingering sweet, astringent, volatile off-note), each panellist scored the test solutions in comparison to the base solution (solution of 5 % sucrose and 0.03 % citric acid). A score of 0 indicated that the taste aspect was the same, 1 indicates slightly higher, 2 indicates higher, 3 indicates much higher, -1 indicates slightly lower, -2 indicates lower and -3 indicates much lower.
Results
The average score for each test solution for each taste aspect was calculated. The results are shown in Table 20 below. Table 20
Two new minor cucurbitane glycosides along with known 11-oxo-mogroside and neomogroside were purified from the commercial extracts of Luo Han Guo ( Siraitia grosvenorii (Swingle) C. Jeffrey ex Lu et Z. Y. Zhang). By extensive NMR and LC-MS analyses and chemical synthesis, the structures of the two new compounds iso- mogroside VI (1) and 11-epi-mogroside V (2) were elucidated as 3-0-B-D- glucopyranosyl(1®6)-B-D-glucopyranosyl-mogrol-24-0-(B-D-glucopyranosyl-(1®6)-[B- D-glucopyranosyl-(1®4)-B-D-glucopyranosyl-(1®2)]-B-D-glucopyranosyl and 3-0-B-D- glucopyranosyl(1®6)-B-D-glucopyranosyl-11B-OH-mogrol-24-0-B-D-glucopyranosyl- (1®6)-[B-D-glucopyranosyl-(1®2)]-B-D-glucopyranosyl, respectively. The sweet potency of iso-mogroside VI and 11-epi-mogroside V were evaluated as 91 and 35 times of sweetness of sucrose, respectively (100 ppm iso-mogroside VI sweet equivalent to 0.91% sucrose; 374 ppm 11-epi-mogroside V sweet equivalent to 1.31% sucrose). Through our course of identifying the new and known mogrosides with five or six glucopyranosyls, a new strategy for glucopyranosyl sugar chain elucidation and assignment was developed. The new strategy based on HSQC-TOCSY experiments with different mixing times featured a quick and unambiguous elucidation and assignment of glucopyranosyl oligosaccharide chains. The previous confusion regarding the structures of neomogroside and mogroside VI was reviewed and clarified after the confirmation of neomogroside structure by our extensive NMR spectral analysis.
