Abstract

The invention relates to a method for preparing soy sauce, and the method comprises the following steps of: cooking soybean cakes or soybeans and mixing the soybean cakes or the soybeans with flour; cooling and inoculating Aspergillus oryzae yeast essence to prepare yeast; mixing the yeast with salt water with the weight which is 1-3 times as much as the yeast; heating at 45-55 DEG C for 1-2 hours and cooling to 20-30 DEG C; and after fermenting for 60-90 minutes by utilizing a high-salt diluted soy sauce brewing method, squeezing and filtering to obtain a soy sauce raw liquid. Compared with the common soy sauce, the soy sauce prepared by the invention has the advantage that the peptide content is improved by more than 50%.

Description

technical field [0001] The invention relates to the technical field of soy sauce condiment production, in particular to a soy sauce preparation method capable of increasing the peptide content in soy sauce, especially the peptide content in soy sauce crude oil. Background technique [0002] Soy sauce, fermented bean curd, tempeh, and soybean paste are known as the four traditional fermented soybean products in my country. It has a history of more than 2,000 years and is welcomed by consumers for its unique and delicious taste. During the fermentation process of soy sauce, various enzymes secreted by Aspergillus oryzae are used to catalyze and decompose the protein, starch and oil in the raw materials to form the main components of soy sauce: small molecule peptides, amino acids, sugars and free fatty acids and other substances. Among them, soybean protein and protein in flour are degraded into soluble protein, peptide and a small amount of free amino acid under the action of...
