Definitions
- the present invention relates to a process for the preparation of a flavoring agent by enzymatic treatment of yeast, the flavoring agent obtained and its uses.
- Yeast extracts are commercially available in the form of powder and paste, and are widely used in the food industry as a flavoring agent. Yeast extracts are defined as concentrates of the soluble fraction of yeasts generally obtained by autolysis or hydrolysis.
- Autolysis is essentially a process aimed at damaging the plasma membrane of yeast by activating the proper yeast degradation enzymes (proteases) and resulting in solubilization of intracellular compounds.
- the yeast extracts can also be obtained by hydrolysis using exogenous reagents or enzymes which allow the release of the intracellular content in a highly degraded form.
- Yeast extracts have been widely accepted in the food industry under the name of natural flavoring agents. They are also very competitive financially, compared to other flavoring agents (which are often unnatural), with equivalent aromatic intensity.
- the main conversion taking place is the degradation of proteins into peptides and amino acids.
- the resulting autolysates therefore have a bitter flavor and a pronounced typical yeast note.
- Another disadvantage is that the autolysates mainly contain only 3'-ribonucleotides, which have no contribution in terms of flavor, since the endogenous ribonucleases convert intracellular PARN to 3'-ribonucleotides.
- yeast autolysates include amino acids, peptides, nucleic acids such as 5'-nucleotides, saccharides and organic acids.
- nucleic acids such as 5'-nucleotides, saccharides and organic acids.
- the 5'-nucleotide content is of considerable importance for flavor and flavor.
- nucleic acids are used as crude compounds in the flavoring of food preparations, for example 5'-inosine mono-phosphate (5'-IMP) or 5'-guanosine mono-phosphate (5'-GMP), but also find applications in the development of pharmaceuticals.
- the unami flavor is considered the fifth basic flavor as well as the sweet, salty, bitter and sour flavors.
- the 5'-nucleotides with high flavor enhancer are also generators of the unami flavor, and thus enhance the effect of mono sodium glutamate (MSG), naturally present in yeast extracts.
- MSG mono sodium glutamate
- Obtaining 5'-nucleotides requires the hydrolysis of the crude RNA by means of a very specific enzyme, 5'-phosphodiesterase (5'-PDE).
- 5'-PDE 5'-phosphodiesterase
- Cohn and Volkin (1953) were the first to demonstrate the presence of 5'-phosphodiesterase activity in snake venom. Despite its high efficiency, it can not be used in the agri-food industry for obvious reasons.
- Other important sources of 5'-PDE include certain fungi such as Penicillium citrinum and some Actinomyces such as Streptomyces aureus.
- 5'-PDE from Penicillium citrinum is commercially available from Amano Enzyme among others, under the name Nucléase RP-IG (or EC3.1.30.1). Because of its very high cost, this enzyme is mainly used on an industrial scale in an immobilized form. Its use in a process for producing yeast extracts enriched with 5'-nucleotides induces very large additional enzymatic costs.
- 5'-PDE The presence of 5'-PDE activity in certain plant germs has been demonstrated by Schuster (1957). Numerous subsequent studies have been the subject of patent applications and mainly describe methods for producing 5'-nucleotide-rich yeast extracts from extracts of malt rootlets (the malt being germinated barley). . Malt is a by-product of the brewing industry, and therefore can be a cheap source of enzyme for the production of 5'-nucleotides from yeast RNA. In this case, 5'-PDE is prepared by simple decoction of a malt root powder in an aqueous solution containing zinc acetate to stabilize the enzyme, and its use induces a small additional cost for the manufacture of yeast extract enriched in 5'-nucleotides product.
- 5'-PDE from germinated malt or barley
- barley contains hordein, a prolamine close to wheat gliadin, which is allergenic and causes intolerance (celiac disease).
- barley is listed in EC Directive 2000/13 / EC, amended by EC Directive 2003/89 / EC as a cereal containing gluten.
- allergenic products containing barley or its derivatives are subject to labeling.
- the main characteristic of these proteins is that they are not degraded by the acid environment of the stomach, nor by the intestinal digestive enzymes.
- these proteins are absorbed as such by the intestine and can trigger an immune response.
- celiac disease it is the consumption of these prolamins that causes a reaction of the body.
- All these prolamins proteins are toxic to so-called celiacs, because their consumption causes a strong inflammatory reaction that damages the surface of the cells of the small intestine. This has the effect of reducing their ability to absorb nutrients such as proteins, fats, carbohydrates, vitamins and minerals. Allergy is associated with symptoms of gastrointestinal nature: abdominal cramps, bloating and chronic diarrhea. From these can arise the malabsorption of several nutrients (iron, calcium, folic acid), malnutrition (anemia and weight loss), fatigue, bone pain, muscle cramps and irritability.
- barley malt PDE Purification of barley malt PDE may be an alternative if the enzyme can be separated from barley prolamine.
- Ai-Yu Wang et al. ((1993) Biochemistry and Molecular Biology International, pp 1095-1102, Vol 29, No. 6), or by Beluhan et al. ((2003) in Biotechnology Letters 25, pp. 1099-1103) focused on characterizing purified barley malt 5'-PDE without measuring the presence of barley prolamine in their preparations.
- This purification alternative appears expensive and does not exonerate from an analytical record demonstrating the elimination of gluten from the enzyme preparation but above all from a clinical record proving the absence of allergenicity of the product resulting from the action of this enzyme. .
- a second alternative is to use a 5'-PDE of microbial origin obtained from strains of filamentous fungi such as Penicillium citrinum or Aspergillus niger, or bacteria such as Actinomyces or Streptomyces.
- filamentous fungi such as Penicillium citrinum or Aspergillus niger
- bacteria such as Actinomyces or Streptomyces.
- a third alternative would be to clone a plant 5'-PDE in an industrial microorganism. This alternative has been evaluated by the teams of researchers of the Applicant, but, besides the fact that the sequences coding for this enzyme are not known, this would lead to an enzyme derived from a genetically modified organism (GMO), product type. still very badly perceived by the different customers users.
