Embodiment 1

[0029] This embodiment provides a method for extracting, separating and purifying taste peptides from Grifola frondosa with an amino acid sequence of Arg-Ser-Gly-VaL (RSGV), and the specific steps are as follows:

[0030] Step (1): Obtaining the oligopeptide water-soluble extract of Grifola frondosa

[0031] Raw materials: Add 100g of Grifola frondosa powder (the dry product of Grifola frondosa was purchased in Qingyuan, Zhejiang), add deionized water according to the material-to-liquid ratio of 1:20, and extract it with a flash high-speed extractor for 2 minutes at a speed of 11000r / min. Then high-pressure cooking was used to pretreat Grifola frondosa at a pressure of 40kPa for 1.5 hours; then the crude extract was refrigerated and centrifuged at 7000rmp at 4°C for 15min; the supernatant was filtered through a 0.45μm microporous filter for later use ;

[0032] Step (2): Separation and purification of Grifola frondosa oligopeptide extract

[0033] The filtrate is separated b...

Abstract

The invention discloses grifola frondosa flavor peptide which is characterized in that the amino acid sequence of the grifola frondosa flavor peptide is Arg-Ser-Gly-VaL. The preparation method comprises the following steps: extracting water-soluble components from grifola frondosa through high-pressure cooking; carrying out ultrafiltration on the water-soluble components; and then carrying out further separation and purification on the ultrafiltration components. Maillard reaction is carried out by utilizing the grifola frondosa flavor peptide prepared by the embodiment, so that the grifola frondosa Maillard reaction peptide with a good flavor enhancing effect is obtained.

Description

technical field [0001] The invention belongs to the field of food science, and relates to a condiment, in particular to a preparation method and application of a taste peptide from frondosa frondosa. Background technique [0002] Taste is an important indicator for evaluating food quality at present. Small molecular peptides, amino acids, nucleotides, inorganic ions, etc. will all make an important contribution to the taste of food. The taste of food is a series of taste sensations, such as sour, sweet, bitter, salty, fresh, etc., produced by small molecular taste substances stimulating the corresponding taste bud cells in the human taste organ tongue. Different taste substances combine with different taste bud cells to produce their own characteristic taste. [0003] The various taste effects of peptides in food show different taste sensations, such as sour, sweet, bitter, salty, and fresh, due to the difference in peptide chain length, amino acid composition, and arrangem...
