Title:
HIGH-CLARITY SOYBEAN FLAVOR PEPTIDE, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/057266
Kind Code:
A1
Abstract:
A high-clarity soybean flavor peptide, a preparation method therefor, and use thereof. The preparation method for the high-clarity soybean flavor peptide comprises the following steps: mixing soybean and/or soybean meal with water and performing colloid milling to obtain a soybean protein slurry; adding protease and cellulase, performing filtering when hydrolysis degree reaches 10-15%, and then performing separation by a separator to obtain intermediate clear liquid which is soybean flavor peptide liquid, wherein the protease consists of papain and flavourzyme; adjusting a pH value of soybean flavor peptide liquid to 4.2-4.5, performing concentration under reduced pressure in vacuum, and performing heat preservation at 45-50°C for 2-3 hours; performing filtration, heating a filtrate to 90°C, performing heat preservation for 1.0-1.5 hours, and performing spray-drying to obtain the high-clarity soybean flavor peptide. The method uses the flavourzyme to release a hydrophobic group in a soybean protein, then promotes occurrence of proteoid reaction and accelerates aggregation of the hydrophobic group by changing the pH value and moisture content in a soybean protein enzymatic hydrolysate, and a filter is combined to efficiently remove a water-insoluble substance.
