Abstract

The invention provides 'high-quality seafood peptide' for preparing a natural peptide-rich flavor enhancer and a preparation method thereof. The preparation method mainly comprises the following steps of: raw material pretreatment; controllable enzymolysis: mixing serum, adding water to regulate the serum till the concentration of the mixed serum is 30 to 50 weight percent, regulating the pH value to between 6.0 and 8.0, adding papain to perform hydrolysis, regulating the pH, heating the mixture, adding composite flavor protease into the mixture, hydrolyzing the mixture, controlling the solid concentration to be between 10 and 15 percent, and inactivating the enzyme after the enzymolysis is finished to obtain a hydrolysis product; centrifuging and filtration; fermentation and fishy smell removal: sterilizing the enzymolysis solution, then cooling the enzymolysis solution to room temperature, inoculating lactic acid bacteria according to the weight of the enzymolysis solution, and fermenting the solution to obtain fermentation solution without fishy smell; ultra-filtration: diluting the fermentation solution till the solid concentration is 2 to 5 percent, and obtaining a short peptide-rich product with a molecular weight of below 6,000Da through an ultra-filtration membrane with a cut-off molecular weight of 6,000Da; concentration; high-pressure homogenization; and spray drying. The prepared flavor enhancer has double effects on flavor and nutrition, and can be widely applied to the food field of condiments, meat products, quick-frozen products, instant noodles, expanding leisure food and the like.

Description

technical field [0001] The invention relates to the fields of food science and food biotechnology processing, in particular to a peptide-rich umami flavor agent "excellent fresh peptide" using natural seafood as a raw material and a preparation method thereof. Background technique [0002] Umami agents or flavor enhancers are substances that supplement or enhance the original flavor of food. The umami taste agent has a taste, and umami taste is different from the basic taste (sour, sweet, bitter, salty), it is a compound taste. At present, the umami taste agents approved and licensed in my country include monosodium glutamate (L-sodium glutamate), taste nucleotide disodium (5'-guanylate disodium and 5'-inosinate disodium), scallops (disodium succinate), L-alanine, glycine, plant hydrolyzed protein (HVP), yeast extract, etc. Among them, L-sodium glutamate, disodium 5′-guanylate and disodium 5′-inosinate, disodium succinate, L-alanine, and glycine are all monomeric umami agen...
