Abstract

The invention relates to a preparation method for peptide-enriched soy sauce. The preparation method comprises the following steps: (1) mixing 1 part of soybean protein by mass with water accounting for 8-15 times of the mass of the soybean protein; adding protease from aspergillus oryzae and hydrolyzing until the hydrolysis degree of the soybean protein is 30%-40%; and carrying out enzyme deactivation to obtain soybean protein hydrolyzing liquid; (2) after cooking 1 part of soya bean meal or soybeans by mass, mixing with 0.2-1 part of flour by mass; cooling and inoculating aspergillus oryzae essence which is 0.02%-1.00%(w / w) of the weight of the soya bean meal or the soybeans and carrying out yeast propagation to prepare finished yeast; and (3) mixing the yeast with the soybean protein hydrolyzing liquid; fermenting by using a high-salt diluted soy sauce brewing method (GB18186-2000) for 60-90 days; and squeezing and filtering to obtain raw soy sauce. The preparation method is simple in production process; the content of small molecule peptides in the soy sauce is improved by more than 45% when being compared with that of common soy sauce; the peptide-enriched soy sauce has no bitter taste; the mouth feel is delicious and mellow and the peptide-enriched soy sauce has a rich soy sauce aroma.

Description

Technical field [0001] The invention relates to food processing technology, to a production method of condiments, in particular to a preparation method of peptide-rich soy sauce. technical background [0002] Soy sauce, fermented bean curd, tempeh, and bean paste are collectively known as the four traditional fermented soy products in my country. They have a history of more than 2,000 years and are welcomed by consumers for their unique and delicious taste. my country is a big country in the production and consumption of soy sauce, with an annual output of about 5 million tons, accounting for about 62.5% of the world's total output. During the fermentation of soy sauce, various enzymes secreted by Aspergillus oryzae are used to catalyze the decomposition of 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. Among them, soybean protein and protein in flour are degraded into solu...
