Problems solved by technology

[0003] However, due to the differences in raw materials, processes and saccharification agents used in vinegar brewing, there are also great differences in its main components. The current standard for brewing vinegar does not clearly stipulate the amino acid content of vinegar flavor and nutritional and health effects. Therefore, many The amino acid content in vinegar products is low, the umami taste is poor, and it is not soft enough; in addition, because the reducing sugar contained in vinegar is low, the sour taste of vinegar is more irritating

Abstract

The invention discloses a method for preparing vinegar with high amino acid and reducing sugar, and relates to a method for preparing vinegar. The method comprises the following steps of: mixing bran, wheat and pea meal to obtain a substrate, and inoculating aspergillus niger As3.3409 and aspergillus oryzae As3.951 to prepare a seed starter; mixing bran, wheat and pea meal to obtain a raw material, and inoculating the seed starter to prepare an uncooked material multi-strain daqu starter; stacking, loading into a pool, turning the starter, and forming the starter; and mixing sorghum flour, wheat flour and millet flour, adding water, adding the cooked material multi-strain daqu starter and a daqu starter into mixed staple food grain, stirring, performing alcoholic fermentation and acetic acid fermentation, sealing, after-ripening, smoking, pouring and drying the vinegar, and ageing to obtain a finished product. By the method, the content of the amino acid and the reducing sugar is greatly improved, the nutritional value of the vinegar is improved, and the irritation of acidity is reduced; and the starter is prepared from an uncooked material and has the advantages of complete enzyme system and multiple microbial fermentation populations of a biological fermentation agent.

Description

technical field [0001] The invention relates to a preparation method of vinegar, in particular to a preparation method of high amino acid and high reducing sugar vinegar. Background technique [0002] As an acidic condiment, vinegar is gradually developing towards nutrition, health care, high-grade, and good taste. Therefore, the development of vinegar with high quality and good taste has become the development direction of many vinegar companies at home and abroad. [0003] However, due to the differences in raw materials, processes and saccharification agents used in vinegar brewing, there are also great differences in its main components. The current standard for brewing vinegar does not clearly stipulate the amino acid content of vinegar flavor and nutritional and health effects. Therefore, many The amino acid content in vinegar products is low, the umami taste is poor, and it is not soft enough; in addition, because the reducing sugar contained in vinegar is low, the so...
