Definitions

  • the present invention relates to chilled nutritional emulsions, and methods of making them, having improved viscosity and mouthfeel characteristics
  • Some of these nutritional beverages contain reduced caloric densities to thus provide a low calo ⁇ e food product for use in helping to maintain a healthy body weight
  • These low calorie formulas often contain reduced fat concentrations, which can have an undesirably thin or watery texture unless additional ingredients are added to affect product viscosity
  • soluble fibers or materials rich in such fibers are typically in the form of indigestible soluble fibers such as alginates, carrageenan, agar, pectin, guar gum, Xanthan, beta-glucan, and so forth, all of which have geliing or water-retention characteristics that ultimately increase product viscosities
  • soluble fibers can make processing more difficult, especially since the higher resulting viscosity also requires a longer and more severe sterilization process to produce an acceptable level of heat penetration
  • severe heat treatment during sterilization may result in an increase in the production of Masllard reaction products that may affect the color and flavor of the beverage and may, therefore, decrease the general sensory acceptance of the beverage
  • the use of a high level of soluble fibers may also actually destabilize emulsions and impart a slimy mouthfeel to the beverage
  • the nutritional emulsion may have a desirable viscosity, but it will not typically have the creamy mouthfeei normally associated with higher fat levels.
  • a first embodiment of the present invention is a nutritiona! emulsion comprising fat, protein and carbohydrate, including a V-complex comprising a food grade surfactant complexed with a polydextrose having an average degree of polymerization of at least about 10, wherein the nutritional emulsion has a first viscosity at 20° C of less than about 300 cps and a second viscosity at a temperature of from 0° C to 8° C that is at least about 50cps higher than the first viscosity.
  • a second embodiment of the present invention is a nutritional emulsion comprising fat, protein and carbohydrate, including an aqueous phase comprising a food grade surfactant and a polydextrose having an average degree of polymerization of at least about 10, wherein the nutritional emulsion has a first viscosity at 20° C of less than about 300 cps and a second viscosity at a temperature of from 0° C to 8° C that is at least about 50 cps higher than the first viscosity.
  • a third embodiment of the present invention is a method of preparing a nutritional emulsion, said method comprising (a) forming an aqueous slurry, substantially free of fat, by combining a food grade surfactant with a polydextrose having an average degree of polymerization of at least about 10; (b) combining and homogenizing the aqueous slurry with fat and protein to form a nutritional emulsion having an aqueous phase comprising from about 10% to 100% by weight of the food grade surfactant and from about 10% to 100% by weight of the polydextrose, wherein the nutritional emulsion has a first viscosity of iess than about 300 cps as measured at 20° C and a second viscosity as measured at between about 0° C and about 8° C that is at least about 50 cps higher than the first viscosity.
  • the resulting nutritional emulsion may be further characterized by the presence of a V-complex formed by the combination of some or all of the polydextrose and food grade surfactant in the aqueous phase.
  • the various embodiments of the present invention provide nutritiona! emulsions that have a tower viscosity during processing and storage, but also have a surprisingly higher viscosity when chilled. As a chilled beverage, the nutritional emulsions also have a surprisingly thick and creamy texture or mouthfeel.
  • Various embodiments of the present invention may include nutritional emulsions, and methods for making those emulsions, all of which may comprise selected V-com ⁇ iexes as defined herein and/or an aqueous phase comprising selected combinations of a polydextrose and a food grade surfactant.
  • Such nutritional emulsions include classic emulsions (e.g., complex, water-in-oil, oil-in-water, etc.), suspensions (e.g., suspended solids), and combinations thereof.
  • the nutritional emulsions are most typically oil-in-water emuisions having a continuous aqueous phase and a discontinuous oil phase.
  • Viscosity values as used herein, unless otherwise specified, are obtained using a Brookfield Viscometer (Model DV-11+) with a 62 spindle at room temperature (20° C), or at the temperature so designated. The viscosity is measured by operating the viscometer at a spindle speed that is the highest speed possible to obtain a reading that is on scale. The measured viscosity values represent the ratio of shear stress to shear rate, expressed as dynes-second/cm2, or poise, or more typically as centipoise (cps) or one hundredth of a poise.
  • compositions and methods of the present invention may be substantially free of any specific ingredient described herein, provided that the remaining composition comprises ail of the essential limitations as defined herein.
  • the term "substantially free” means that the compositions may comprise less than a functional amount of the identified ingredient disclosed herein, typically less than about 1 %, including less than about 0.5%, also including less than about 0.1 %, and also including zero percent, by weight of the identified ingredient.
  • compositions and methods of the present invention may comprise, consist of, or consist essentially of the essential elements of the invention described herein, as well as any additional or optional ingredients or components described herein or otherwise useful tn a nutritional application.
  • food grade surfactant as used herein, unless otherwise specified, means the surfactant component of the carbohydrate-surfactant complexes (V-complexes) described herein.
  • the nutritional emulsion embodiments of the present invention are emulsions having a viscosity as measured at room temperature (20° C) of less than about 300 cps, typically from about 10 cps to about 160 cps, and more typically from about 20 cps to about 70 cps.
  • the nutritional emulsion may be cooled or chilled to a temperature of from about 0° C to about 8° C, including from about 1° C to about 6° C, and a ⁇ so including from about 2° to about 4° C, at which point the viscosity of the chilled nutritional emulsion increases by at least about 50 cps, including an increase of from about 100 to about 700 cps, and also including an increase of from about 150 cps to about 350 cps, above the corresponding room temperature viscosity,
  • the chilled nutritional emulsion which will therefore have a viscosity higher than the nutritional emulsion at room temperature, will typically have a chilled viscosity of at least about 120 cps, including from about 120 cps to about 600 cps, also including from about 150 cps to about 450 cps, and also including from about 200 cps to about 400 cps.
  • the nutritional emulsions are typically in the form of aqueous emulsions, including milk- based (soy or cows milk) or other oil-in-water emulsions, most typically miik-based emulsions.
  • the nutritional liquids may be formulated with sufficient kinds and amounts of nutrients to provide a potential sole, primary, or supplemental source of nutrition, or to provide a specialized nutritional emulsion for use in individuals afflicted with specific diseases or conditions.
  • the nutritional emulsion embodiments of the present invention may be characterized by the presence of a V-complex comprising a food grade surfactant in combination with a poiydextrose having an average degree of polymerization of at least about 10.
  • the V- complex may be formed prior to or during the manufacturing process, such as in accordance with the processing methods described herein.
  • V-complex refers to carbohydrate-surfactant complexes formed by a combination that is substantially free of fat and comprises a food grade surfactant and a polydextrose (i.e., ⁇ ⁇ 1 ,4) linked glucose polymer) having an average degree of polymerization of at least about 10.
  • the selected glucose polymers form Seft-handed, 6-residue helices with a hydrophobic core. Under appropriate processing conditions, this hydrophobic core traps the hydrophobic section of the food grade surfactant to form a carbohydrate-surfactant complex having a distinctive V-complex r-ray diffraction pattern. This type of complex is referred to herein as a V-compiex.
  • the nutritional emulsions may be evaluated for the presence of the V-complex. This may be done indirectly by either measuring the viscosity change when the product is refrigerated or cooled as described herein, and or by evaluating the product by conventional x-ray diffraction methods for the presence of the V-complex. Such x-ray diffraction methods are described, for example, by J-L Jane and Robyt, J. ⁇ 1984) Carbohydrate Research 132:105. Journal of Rheology - May 1998 -- Volume 42, Issue 3, pp. 507-525 Mercier, C 1 R. Charbonniere, J. Grebaut, and J. F. de La Gueriviere.
  • Inclusion or formation of the V-complex in the nutritional emulsion affects the resulting rheology profile of the nutritional emulsion.
  • the nutritional emulsion, with the V- complex in the aqueous phase of the emulsion has a relatively low viscosity at room temperature (20° C), but when chilled has a significantly higher viscosity as the temperature drop further facilitates the formation of the V-complex within the aqueous phase, which then imparts both viscosity and a creamy mouthfeel to the emulsion.
  • the lower viscosity during manufacture allows for reduced processing or sterilization temperatures. This may reduce manufacturing costs as well as reduce the rate or extent of formation of undesirable Malliard reaction products in the finished product.
  • the V-complex in the nutritional emulsions provides a creamy mouthfeeS when consumed.
  • creamy means that the product has a mouthfeel similar to a nutritional emulsion having a higher fat content.
  • the nutritional emulsions are therefore especially useful when formulated as a low fat formulation since the V-complex compensates for the watery-mouthfeel commonly associated with reduced fat content in an emulsion.
  • the V-compiex may be formed within the nutritionaS emulsions by methods described herein. This typically involves combining the food grade surfactant with the polydextrose in a separate aqueous slurry, substantially free of fat, that is then used to form part or ali of the aqueous phase of the emulsion.
  • the selected the food grade surfactant and polydexirose may be dispersed in an aqueous slurry during processing, under conditions that melt and disperse the food grade surfactant throughout the aqueous slurry, and thereafter combined and homogenized with other fat and protein ingredients to form a nutritional emulsion.
  • the nutritional emulsion may contain other surfactants in addition to the food grade surfactant in the aqueous phase, especially to help emulsify the oil component in the emulsion, but these oil phase surfactants do not form the desired V-complex with the polydextrose as described herein.
  • Oil blends added to the nutritional emulsion typically contain from 1 to 6% surfactants by weight of the oil.
  • substantially free of fat means that the referenced materia!, either the aqueous phase of the nutritional emulsion or the aqueous slurry used in preparation of the nutritional emulsion, contains less than about 0.1 %, including less than 0.05%, and also including zero percent by weight of fat. It is understood, however, that such exclusion does not apply to the food grade surfactant, which in the case of an acylglyceroi could be considered a fat.
  • the aqueous slurry comprising the food grade surfactant and the selected carbohydrate are typically heated to melt the surfactants and mixed sufficiently to disperse or dissolve the surfactant and selected carbohydrate, to thus promote the interaction of those ingredients to form the desired V-complexes therefrom.
  • the resulting v-complex slurry may then be added with other ingredients in accordance with conventional or otherwise known processing steps for manufacturing the desired nutritional emulsion.
  • the aqueous slurry is most typically heated to a temperature above the melt point of the surfactant, which heat may be added in the form of a heated carbohydrate mixture added to the surfactant, with a subsequent melting of the surfactant in newly formed aqueous slurry.
  • V-compiexes are essentially tiny particles that can be digested by saliva enzymes, they impart a thick, creamy mouthfeef similar to that of a rich oil-in-water type emulsion, e.g., milk-based or other fat based emulsion, even when the nutritional emulsion contains relatively low fat levels (which should otherwise result in a thin, watery mouthfeel ⁇ .
  • the nutritional emulsion embodiments of the present invention are distinct from the many prior art compositions that merely comprise food grade surfactants and a polydextrose, but do not combine the latter two ingredients in the aqueous phase of an emulsion or otherwise form a V-complex in that aqueous phase.
  • the mere inclusion of these two ingredients in a composition is not sufficient to achieve the desired viscosity benefit, unless they are also combined or otherwise complexed within the aqueous phase of the nutritional emufsion.
  • the polydextrose component of the aqueous phase or of the V-complex has an average degree of polymerization of at least about 10, including from about 20 to about 400, also including from about 40 to about 200, and also including from about 60 to about 100.
  • degree of polymerization and “average degree of polymerization” are used interchangeably to mean an average degree of polymerization value.
  • the degree of polymerization (DP) is an art recognized term referring to the number of glucose or monomer units in a polymer,

  • the nutritional emulsions may be manufactured by any conventional or otherwise known method for making nutritional emulsions, most typically for making nutritional emulsions or milk based emulsions, except that the formulation must include or accommodate the essential process steps described herein for the formation of the specified aqueous phase or V-complex.
  • Most typicaiiy two or more separate slurries are prepared, one of which must be an aqueous slurry that is substantially free of fat and comprises the food grade surfactant in combination with the selected maltodextrin or starch.
  • Other slurries may include a protein in fat/oil slurry (e.g., protein, fat, emulsifier or surfactant in addition to the food grade surfactant in the aqueous slurry), a protein in water slurry (e.g., protein, water), and additional carbohydrate slurries.
  • the multiple slurries are eventually combined together in a blend tank, subjected to ultra high temperature processing, homogenized, infused with added vitamins or other optional ingredients, diluted with water as appropriate.
  • the resulting nutritional emulsions may then be aseptically packaged or otherwise filled into retort stable packages and then subjected to retort sterilization.
  • Nutritional emulsion embodiments of the present invention are prepared by combining the following ingredients in accordance with the method embodiments of the present invention.
  • CHO T PIW, and PIF slurries are prepared separately.
  • the ingredients are mixed together for that slurry under temperature and shear appropriate for the selected materials, after which the different slurries are combined in a biend tank, subjected to ultra high temperature treatment (UHT) and then homogenized at about 3000 psi. Vitamins are then added to the homogenized mixture.
  • UHT ultra high temperature treatment
  • the resulting mixture is diluted with water as needed to achieve the desired concentrations.
  • the final mixture is then filled into retort stable 8 oz plastic bottles and then subjected to retort sterilization.
  • the packaged nutritional emulsion is characterized by the presence of an aqueous phase having a V-compiex comprising the food grade surfactant comp ⁇ exed with the selected maltodextrin or starch component, or by the presence within the aqueous phase of at least about 10% by weight of the food grade surfactant and at least about 10% by weight of the polydextrose (maitodextrin or starch).
  • the retort-packaged products are then labeled with instruction to cool or refrigerate prior to use.
  • the nutritional emulsions are removed from the package and tested for the presence of the v ⁇ complex.
  • Each of the resulting retort packaged nutritional emulsions has a viscosity as measured at 20° C of between about 20 and 160 cps. Each is refrigerated to between 0° and 8° C and develops a chilled viscosity of between about 220 and about 350 cps that is then consumed as chilled.
  • the chilled emulsion has a thick, creamy mouthfeel.
  • Examples 1-3 are repeated and, instead of retort sterilization, the resulting nutritional emulsions are asepticaSly packaged into 8 oz plastic containers.
  • the packaged nutritional emulsions are characterized by the presence of an aqueous phase having a V-complex comprising the food grade surfactant complexed with the selected maltodextrin or starch component, or by the presence within the aqueous phase of at least about 10% by weight of the food grade surfactant and at least about 10% by weight of the polydextrose (maltodextrin or starch).
  • the aseptically packaged products are then labeled with instruction to cool or refrigerate prior to use.
  • Each of the resulting retort packaged nutritional emulsions has a viscosity as measured at 20° C of between about 20 and 160 cps. Each is refrigerated to between 0° and 8 D C and develops a chilled viscosity of between about 220 and about 350 cps that is then consumed as chilled, The chilled emulsion has a thick, creamy mouthfeel.
