Description

TASTE MODIFYING PRODUCT
Related Applications
This Application is related to Australian Patent Application Nos. 2016202142 and 2014216011, and Australian Patent No. 2012278120 (a national phase entry of PCT/EP2012/060641). The entire contents of the abovementioned patent and applications are incorporated herein by reference.
Technical field
The present invention relates to the field of taste. More particularly, it concerns the use of certain cinnamic acid derived amides as taste-enhancing ingredients to impart or reinforce the tastes known as kokumi or umami.
The present invention also concerns compositions or articles containing at least one of the aforementioned compounds.
Background and Prior art
Various cinnamic acid derived amides are known to naturally occur in plants such as Zanthoxylum rubescens (Rutaceae) [Amides from Zanthoxylum Rubescens. Adesina, S.K.; Reisch, J. Phytochem. 1989, 3, 839-842.] or Piperaceae [Chemical constituents of peppers (Piper spp.) and application to food preservation: naturally occurring antioxidative compounds. Nakatani, N.; Inatani, R.; Ohta, H.; Nishioka, A., Environ. Health Perspectives 1986, 67, 135-142],
Since vanilloid amides, such as capsaicin or piperine are usually found in pepper or capsicum species, they generally have a pungent or hot taste. It would be desirable to avoid this. US2003/0152682 (Bayer Polymers LLC) and EP 1 323 356 (Symrise) disclose the use of ferullic acid amides as pungent compounds or heat generating-system for oral hygiene products. Included in this document is the compound trans-rubenamine, but it is not described or even suggested to have an umami taste. EP 2 138 152 (to Henkel) describes mouthwash compositions containing ferrulic acid derived amides among other amides or pungent, or cooling compounds. However, none of these documents anticipate, report or suggest that the compounds described therein have organoleptic properties that can be used to impart or reinforce a kokumi or umami taste.
In New Developments in Umami (Enhancing) Molecules, Winkel et al, Chemistry & Biodiversity, Vol 5 (2008), pi 195-1203, a review of known umami modifying compounds is given. However, there is no suggestion of the compounds of the present invention.
Kokumi and umami are now established descriptors in the field of taste and are known to supplement, enhance, or modify the taste and/or aroma of a food without necessarily having a strong characteristic taste or aroma of their own. A desire for kokumi
2017279654 17 Jan 2019 and umami exists for a wide range of foods like soups, sauces, savory snacks, prepared meals, condiments, etc. Moreover, they are often found to complement or enhance foodstuffs which have a savory or salty characteristic and, as a result, may be useful where sodium or salt reduction is desired.
Umami is one of the five basic tastes sensed by specialized receptor cells present on the human tongue. Umami applies to the sensation of savoriness, and particularly to the detection of glutamates and/or ribotides which are common in meats, cheese and other protein-rich foods. The behavior of umami receptors explains why foods containing monosodium glutamate (MSG) often taste fuller. However, some consumers are apparently sensitive to MSG and may suffer from headaches or other illnesses upon consuming it. Thus replacement of MSG, at least partially, can be desirable.
Kokumi has been described variously as “deliciousness”, “continuity”, mouthfulness, “mouthfeel” and “thickness”. It exists naturally in a variety of foods such as cheese, giving a ‘mature’ cheese taste; vegetable flavors, particularly tomato; meat, where it gives a fullness and longer lasting taste; mayonnaise & dressings, where it can round out acid notes; fat-reduced food products, where it gives a similar fullness to full-fat products; herbs and spice; and soups, especially miso soup.
US2006/057268 reports saturated or unsaturated N-alkamide and their use as umami ingredients.
It would be desirable to provide a flavor or taste enhancing ingredient that has umami or kokumi characteristics. It would be even more desirable to provide a flavor or taste enhancing ingredient that has umami and kokumi characteristics.
Description of the invention
We have now surprisingly discovered that a certain class of cinnamic acid derived amide derivatives can be used as flavor or taste enhancing ingredients, for instance to impart or reinforce the kokumi or umami taste of a flavoring composition or of a flavored food.

According to any one of the above embodiments of the invention, the nonaromatic carbon-carbon double bond of compound (I) or (II) can be in a configuration Z or E or a mixture thereof. According to any one of the above embodiments of the invention, said compound (I) or (II) is in the form of a mixture of the E and Z stereoisomers, said mixture comprising at least 50% w/w, or at least 80% w/w, of the stereoisomer E, the remaining being essentially the Z stereoisomer.
According to a particular aspect of the present invention, said compound (I) is selected amongst (E)-3-(3,4-dimethoxyphenyl)-N-(4-methoxyphenethyl)acrylamide (referenced in the Examples as Amide 1), (E)-3-(3,4-dimethoxyphenyl)-N-(310 methoxyphenethyl)acrylamide (referenced in the Examples as Amide 4), (E)-3-(3,4dimethoxyphenyl)-N-(3-ethoxyphenethyl)acrylamide (referenced in the Examples as Amide 7), (E)-3-(3,4-dimethoxyphenyl)-N-(3-propoxyphenethyl)acrylamide (referenced in the Examples as Amide 8), (E)-3-(3,4-dimethoxyphenyl)-N-(4-isopropoxyphenethyl) acrylamide (referenced in the Examples as Amide 9), (E)-3-(3,415 dimethoxyphenyl)-N-(4-ethylphenethyl)acrylamide (referenced in the Examples as Amide 10), (E)-3-(3,4-dimethoxyphenyl)-N-(3,4-dimethylphenethyl)acrylamide (referenced in the Examples as Amide 11), (E)-3-(3,4-dimethoxyphenyl)-N-(4isopropylphenethyl)acrylamide (referenced in the Examples as Amide 12) or (E)-3-(3,4dimethoxyphenyl)-N-(3-methylphenethyl)acrylamide (referenced in the Examples as
Amide 17).
The compounds of the invention can be used alone or in mixtures and provide a strong kokumi or umami taste at exceptionally low levels.
As mentioned above, the invention concerns the use of a compound of formula (I) as a taste-conferring or enhancing ingredient, and in particular to impart or reinforce kokumi or umami taste.
According to a particular embodiment of the invention, said compound (I) is used to impart or reinforce kokumi or umami taste as well as to enhance the saltiness and/or savory perception of a flavor.
According to a particular embodiment of the invention, such use is very much 30 appreciated by flavorists to impart or enhance the kokumi or umami taste in savory flavors, such as beef, chicken, pork, and seafood. Surprisingly, in seafood applications such as surimi, or seafood bouillons or snack flavors, compounds according to formula (I) are also found to enhance the perception of sweetness and longevity of the flavor. By
2017279654 20 Dec 2017 contrast, in beef flavors, the compounds according to formula (I) are found to enhance perception of fattiness and tallow notes. Additionally we found that said compounds can increase juiciness in meat based products.
In other words the present invention concerns a method to confer, enhance, 5 improve or modify the taste properties, as indicated above, of a flavoring composition or of a flavored article, which method comprises adding to said composition or article an effective amount of at least a compound of fonnula (I). In the context of the present invention “use of a compound of fonnula (1)” includes the use of any composition containing compound (I) and which can be advantageously employed in the flavor industry as active ingredient.
In another aspect, the invention provides a taste-modifying composition comprising:
i) as a taste-confening or modifying ingredient, at least one compound according to fonnula (I) above;
ii) at least one ingredient selected from the group consisting of a flavor carrier and a flavor base; and iii) optionally at least one flavor adjuvant.
By “flavor carrier” we mean here a material which is substantially neutral from a flavor point of view, insofar as it does not significantly alter the organoleptic properties of flavoring ingredients. The earner may be a liquid or a solid.
Suitable liquid carriers include, for instance, an emulsifying system, i.e. a solvent and a surfactant system, or a solvent commonly used in flavors. A detailed description of the nature and type of solvents commonly used in flavor cannot be exhaustive. Suitable solvents include, for instance, propylene glycol, triacetine, triethyl citrate, benzylic alcohol, ethanol, vegetable oils or terpenes.
Suitable solid carriers include, for instance, absorbing gums or polymers, or even encapsulating materials. Examples of such materials may comprise wall-forming and plasticizing materials, such as mono, di- or trisaccharides, natural or modified starches, hydrocolloids, cellulose derivatives, polyvinyl acetates, polyvinylalcohols, proteins or pectins, or yet the materials cited in reference texts such as H. Scherz, Hydrokolloids : Stabilisatoren, Dickungs- und Gehermittel in Lebensmittel, Band 2 der Schriftenreihe Lebensmittelchemie, Lebensmittelqualitat, Behr's VerlagGmbH & Co., Hamburg, 1996. Encapsulation is a well known process to a person skilled in the art, and may be
2017279654 20 Dec 2017 performed, for instance, using techniques such as spray-drying, agglomeration, extrusion, coacervation and the like.
By “flavor base” we mean here a composition comprising at least one flavoring ingredient.
Said flavoring ingredient is not a compound of formula (I). Moreover, by “flavoring ingredient” it is meant here a compound, which is used in flavoring preparations or compositions to impart a hedonic effect. In other words such an ingredient, to be considered as being a flavoring one, must be recognized by a person skilled in the art as being able to impart or modify in a positive or pleasant way the taste of a composition, and not just as having a taste.
The nature and type of the flavoring co-ingredients present in the base do not warrant a more detailed description here, the skilled person being able to select them on the basis of its general knowledge and according to intended use or application and the desired organoleptic effect. In general terms, these flavoring co-ingredients belong to chemical classes as varied as alcohols, aldehydes, ketones, esters, ethers, acetates, nitriles, terpenoids, nitrogenous or sulphurous heterocyclic compounds and essential oils, and said perfuming co-ingredients can be of natural or synthetic origin. Many of these coingredients are in any case listed in reference texts such as the book by S. Arctander, Perfume and Flavor Chemicals, 1969, Montclair, New Jersey, USA, or its more recent versions, or in other works of a similar nature, as well as in the abundant patent literature in the field of flavor. It is also understood that said co-ingredients may also be compounds known to release in a controlled manner various types of flavoring compounds.
According to a particular embodiment of the invention, said flavor base comprises another umami imparting flavor ingredient, such as MSG (mono sodium glutamate), and ribotides (a blend, e.g. 50-50 w/w, of IMP (inosine monophosphate) and GMP (guanosine monophosphate)), for example in a MSG/ribotides w/w ratio from 95/5 to 90/10. Or ingredients rich in those compounds mentioned before that are well known to the people skilled in the art.
By “flavor adjuvant” we mean here an ingredient capable of imparting additional added benefit such as a color, a particular light resistance, chemical stability, and so on. A detailed description of the nature and type of adjuvant commonly used in flavoring bases cannot be exhaustive. Nevertheless, such adjuvants are well known to a person skilled in
2017279654 20 Dec 2017 the art, but it has to be mentioned that said ingredients are well known to a person skilled in the art.
A composition consisting of at least one compound of formula (I) and at least one flavor carrier represents a particular embodiment of the invention as well as a flavoring composition comprising at least one compound of formula (I), at least one flavor carrier, at least one flavor base, and optionally at least one flavor adjuvant.
In a highly preferred embodiment, more than one compound of formula (I) is used in combination since it is found that a synergistic enhancement of the kokumi or umami taste can be achieved in this way. Moreover, it is found that the combination of ingredients can provide the desired kokumi or umami taste without imparting undesirable flavor notes.
Moreover, a compound of formula (I) can be advantageously incorporated into flavored articles to positively impart, or modify, the kokumi or umami taste of said articles. Thus, in yet another aspect, the present invention provides a flavored article comprising:
i) as taste-conferring or modifying ingredient, at least one compound of formula (I), as defined above, optionally present as part of a flavoring composition; and ii) a foodstuff base.
Suitable foodstuff bases, e.g. foods or beverages, can be fried or not, as well as 20 frozen or not, low fat or not, marinated, battered, chilled, dehydrated, instant, canned, reconstituted, retorted or preserved. Typical examples of said foodstuff bases include:
• a seasonings or condiment, such as a stock, a savory cube, a powder mix, a flavored oil, a sauce (e.g. a relish, barbecue sauce, a dressing, a gravy or a sweet and/or sour sauce), a salad dressing or a mayonnaise;
· a meat-based product, such as a poultry, beef or pork based product, a seafood, surimi, or a fish sausage;
• a soup, such as a clear soup, a cream soup, a chicken or beef soup or a tomato or asparagus soup;
• a carbohydrate-based product, such as instant noodles, rice, pasta, potatoes flakes or 30 fried, noodles, pizza, tortillas, wraps;
• a dairy or fat product, such as a spread, a cheese, or regular or low fat margarine, a butter/margarine blend, a butter, a peanut butter, a shortening, a processed or flavored
2017279654 20 Dec 2017 cheese;
• a savory product, such as a snack, a biscuit (e.g. chips or crisps) or an egg product, a potato/tortilla chip, a microwave popcorn, nuts ,a bretzel, a rice cake, a rice cracker, etc;
· an imitation products, such as a dairy (e.g a reformed cheese made from oils, fats and thickeners) or seafood or meat (e.g. a vegetarian meat replacer, veggie burgers) analogue; or • a pet or animal food.
Particularly preferred foodstuffs in which the compound according to formula (I) 10 finds utility include those having topnotes such as seafood, beef, chicken, vegetables, cheese, fat, tallow and/or marrow are important.
For the sake of clarity, it has to be mentioned that, by “foodstuff’ we mean here an edible product, e.g. a food or a beverage. Therefore, a flavored article according to the invention comprises one or more compounds according to formula (I), as well as optional benefit agents, corresponding to taste and flavor profile of the desired edible product, e.g. a savory cube.
The nature and type of the constituents of the foodstuffs or beverages do not warrant a more detailed description here, the skilled person being able to select them on the basis of his general knowledge and according to the nature of said product.
According to any one of the above embodiments of the invention, the tastemodifying composition and the flavored article according to the invention comprise as taste conferring or modifying ingredient a compound of formula (II) wherein R3 represents a hydrogen atom or represents a R5 group, and R4 represents a R5 or OR5 group, R5 representing a Ci to C3 alkyl group. According to any one of the above embodiments of the invention, R5 represents a methyl, ethyl, propyl or iso-propyl group.
The proportions in which the compounds according to the invention can be incorporated into the various aforementioned articles or compositions vary within a wide range of values. These values are dependent on the nature of the article to be flavored and on the desired organoleptic effect as well as the nature of the co-ingredients in a given base when the compounds according to the invention are mixed with flavoring coingredients, solvents or additives commonly used in the art.
In the case of flavoring compositions, typical concentrations are in the order of 0.05% to 30%, more preferably 0.1% to 20%, most preferably 0.1% to 10%, of the
2017279654 20 Dec 2017 compounds of the invention based on the weight of the flavoring compositions into which they are incorporated. Concentrations lower than these, such as in the order of 0.5 ppm to 300 ppm by weight, more preferably 5ppm to 75ppm, most preferably 8 to 50 ppm, can be used when these compounds are incorporated into flavored articles, the percentage being relative to the weight of the article.
At these levels the taste is typically described as umami-like, lasting, sweet and lingering.
Examples
The invention will now be described in further detail by way of the following example, wherein the abbreviations have the usual meaning in the art, the NMR spectral data were recorded in CDCI3, with a 400 MHz machine for 'll, and a 100 or 125 MHz machine for C, the chemical displacements, δ, are indicated in ppm with respect to TMS as standard, and the coupling constants, J, are expressed in Hz.
Example 1
Preparation of Compound According to the Invention
Synthesis of amides with ethyl chloroformate, general procedure:
The acid (E)-3-(3,4-dimethoxyphenyl)acrylic acid (typically 33 mmol) and DIEA (diisopropyl ethyl amine, 2 equiv.) were diluted in 200 mL of EtOAc and 50 mL of dichloromethane. The solution was cooled to 15 °C and ethyl chloroformate (1 molar equiv.) was added drop wise. The reaction was stirred for 1 hour before the starting amine (1 molar equiv., diluted 2-3 times in EtOAc) was added. The reaction was stirred overnight at room temperature. It was washed with aqueous 5% KHSO4, brine, aqueous 5% NaHCO3, brine, and then dried over Na2SO4 and evaporated under high vacuum for 3 hours. The crude product was purified by flash chromatography (silica gel; cyclohexane/EtOAc, 2:8) or by recrystallization from EtOAc. Yields were between 50 and 80% on the purified product.

Evaluation of the Umami Effect of the Compound according to the Invention (in Water)
a) Pure amide in pure water
The amides were evaluated at 20ppm in mineral water in comparison with 0.05% monosodium glutamate (MSG). The trained panelists (5-10) were giving an umami taste intensity note. The Relative umami intensity (RUI) was calculated as follows:
RUI = (umami intensity of the amide)/(umami intensity of MSG) * 10
The following table gives the average of the notes obtained from all panelists.
Amide N° 1 2 3 4 5 6 7
RUI 5.6 3.8 3.3 10.2 3.2 3.7 9.8
Amide N° 8 9 10 11 12 14 17
RUI 9.9 6.5 11.5 13.3 5.9 3.8 12.1
