Abstract

The invention relates to a method for treating vinegar auxiliary materials by using a steam explosion process to brew mature vinegar and belongs to the technical field of vinegar brewing. The method comprises the steps of: carrying out steam explosion on bran, adding the bran into alcoholic fermented mash as auxiliary materials, and carrying out acetic acid fermentation; smoking fermented grains,carrying out vinegar pouring and carrying out ageing to obtain mature vinegar. Through steam explosion pretreatment, bran component dispersion and structure change are achieved; the mature vinegar brewed by using the bran is high in raw material utilization rate, stable in quality and rich in flavor substances; and the method is shorter in fermentation period, low in production cost, simple in process and wide in application prospect, and is a very efficient and economical raw material treatment mode.

Description

technical field [0001] The invention relates to a method for brewing mature vinegar by treating vinegar auxiliary materials with a steam explosion process, and belongs to the technical field of vinegar brewing. Background technique [0002] Steam explosion (Steam explosion) is a technology for pretreatment of biomass through steam explosion process. The essence of its technology is: to release the steam molecules infiltrated into the plant tissue instantaneously, so that the internal energy of the steam can be converted into mechanical energy and act on the interlayer of biomass tissue cells, so that the raw materials can be decomposed according to the purpose with less energy. This method does not need to add chemical reagents, changes the structure of raw materials through high temperature and high pressure, improves the yield of active ingredients in raw materials, is environmentally friendly and efficient, and is a very promising raw material pretreatment technology. ...
