Definitions

  • the present invention relates to the field of flavors and in particular it concerns the flavoring of an article upon which it is desired to confer or enhance the fullness and harmony of its taste or aroma, i.e. a mouthfeel.
  • the invention relates more particularly to the use as flavoring ingredient of at least one compound selected from the group consisting of (a) an acid of formula
  • A represents a proteogenic ⁇ -amino acid residue, said residue being bonded to the carbonyl group via the ⁇ -nitrogen atom
  • the invention also relates to the flavoring compositions or the flavored articles containing, as flavoring ingredients, at least one of the invention's compounds.
  • A represents a proteogenic ⁇ -amino acid residue, said residue being bonded to the carbonyl group via the ⁇ -nitrogen atom
  • the edible alkaline or alkaline earth metal salts, and the hydrates, of said compounds of formula (I) is particularly useful to the flavor industry.
  • the use as mouthfeel and/or umami agent and/or as a monosodium glutamate (MSG) partial or total replacer is particularly attractive.
  • Said uses consist, for example, in a method to impart, improve or increase the umami character and/or the mouthfeel of a flavoring composition or a flavored article, which method comprises adding to said composition or article an umami and/or mouthfeel effective amount of at least an invention's compound.
  • mouthfeel agent we mean here a flavoring ingredient capable of modifying, imparting, improving or enhancing the taste properties of flavoring compositions or foodstuffs to which they are added, and this in respect of the "mouth impact" of the aroma of said flavoring compositions or foodstuffs.
  • a “mouthfeel agent” according to the invention provides an effect on the roundness and fullness perception of the aroma or taste of products into which it is added.
  • amami agent we mean here a flavoring ingredient capable of imparting what is commonly defined by a skilled person of the art as the umami taste.
  • ⁇ -amino acid residue has the meaning common in the art, that is an ⁇ -amino acid that lacks a hydrogen atom of the ⁇ -amino group, i.e. the group -(HN-CHR-COOH). These residues will henceforth be represented by the three letter abbreviations shown in brackets hereinbelow, which are of current use for defining the structure of polypeptide chains (see, e.g., Eur. J. Bioch. 1984, 138, 9-37). For the sake of clarity, it has to be mentioned also that by "proteogenic ⁇ -amino acid” we mean here any of the twenty amino acids used in nature for the synthesis of proteins.
  • Said amino acids are: L-glycine (Gly), L-alanine (Ala), L-valine (Val), L-leucine (Leu), L-isoleucine (lie), L-proline (Pro), L-serine (Ser), L-threonine (Thr), L-phenylalanine (Phe), L-tyrosine (Tyr), L-tryptophan (Trp), L-lysine (Lys), L-arginine (Arg), L-histidine (His), L-aspartic acid (Asp), L-glutamic acid (Glu), L-asparagine (Asn), L-glutamine (Gin), L-cysteine (Cys) and L-methionine (Met).
  • the invention is therefore concerned with compounds including a C 3 to C 8 dicarboxylic moiety and a residue of proteogenic amino acids mentioned above.
  • the invention's derivative N-(3-carboxypropionyl)-glutamic acid, or succinoyl-Glu has the following structure:
  • the most interesting organoleptic property of the invention's compounds is their ability to impart highly appreciated umami and/or mouthfeel characteristics to the compositions or foodstuffs to which they are added. More specifically, the mouthfeel or mouth impact provided by the presence of the invention's compounds results in a quite remarkable roundness, fullness and harmony of the whole taste of the flavoring compositions or flavored articles. It has to be said that the overall organoleptic effect is different from the one which could be obtained by compounds consisting of a simple salt between the free diacid and the free amino acid, which have a much sharper taste associated with the acid taste and are not able to impart an umami and mouthfeel character to the food in which they are added.”
  • succinoyl derivatives of Glu, Ala or Leu i.e.
  • N-(3-carboxypropionyl)-glutamic acid succinoyl-Glu
  • N-(3- carboxypropionyl)-alanine succinoyl-Ala
  • N-(3-carboxypropionyl)-leucine succinoyl- Leu
  • MSG replacer and/or as mouthfeel and/or umami agents have shown a very good performance as MSG replacer and/or as mouthfeel and/or umami agents, and are able to provide flavoring compositions and flavored articles with very much appreciated organoleptic characteristics.
  • succinoyl-Glu possesses a slightly acidic note together with a well perceivable umami taste or character having a broth connotation, the overall organoleptic impression being accompanied by a good and long lasting roundness and fullness.
  • the compounds succinoyl-Leu and succinoyl-Ala which have a slightly more acidic and slightly less umami taste than the one of succinoyl-Glu, provide similar organoleptic effects.
  • the organoleptic effect of these compounds has been found to be less sweet than the one provided by MSG, conferring thus an advantage to the invention's compounds for a use in savory application, wherein a sweet note may be undesired.
  • Maleyl-Glu imparts also a slightly more juicy feeling
  • glutaryl-Glu and Glutaryl-Leu imparts also a slightly more fatty feeling.
  • At least one invention's compound as defined above at least one invention's compound as defined 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.
  • An invention's composition consisting of at least one invention's compound and at least one flavor carrier represents a particular embodiment of the invention as well as a flavoring composition comprising at least one invention's compound, at least one flavor carrier, at least one flavor base, and optionally at least one flavor adjuvant.
  • flavor carrier we mean here a material which is practically neutral from a flavor point of view, i.e. which does not alter significantly organoleptic properties of flavoring ingredients. Said carrier maybe a liquid or a solid.
  • liquid carrier one may cite, as non-limiting examples, an emulsifying system or a solvent commonly used in flavors.
  • a skilled person in the art is able to select them on the basis of the nature of the product to be flavored.

  • a flavoring composition comprising at least one compound of formula (I) such as succinoyl-Glu, succinoyl-Ala and succinoyl-Leu, and/or a derivative thereof, is particularly useful from the organoleptic point of view.
  • a flavoring composition wherein the flavor base comprises at least a flavoring co-ingredient selected from the group consisting of an extract derived from a single cell organism, a protein hydrolysate and a fat hydrolysate, has proved to be particularly useful as MSG replacer. Indeed, we have found that the presence of at least one of said flavoring co-ingredients increases or boosts the organoleptic effect provided by the invention's compounds.
  • extract derived from a single cell organism we mean here an extract obtained by degradation, e.g. by autolysis, of a single cell organism such as a yeast.

  • examples of such material are hydrolised butter oil.
  • a preferred composition of said invention's embodiments is a flavoring composition wherein the flavor base comprises at least a yeast extract, at least a protein hydrolysate and at least a fat hydrolysate.

  • the flavoring compositions according to the invention may be in the form of a simple mixture of flavoring ingredients or also in an encapsulated form, i.e. a flavoring composition entrapped into a solid matrix.
  • the encapsulation process by which the aroma can be protected may consist of techniques such as spray-drying, agglomeration or yet extrusion; or consists of a coating encapsulation, including coacervation and complex coacervation techniques.
  • Carrier materials used for matrices are wall-forming and plasticizing materials such as mono, di- or trisaccharides, natural or modified starches, hydrocoUoids, cellulose derivatives, polyvinyl acetates, polyvinylalcohols, proteins or pectins.
