Production process for brewing mature vinegar from glutinous sorghum

Abstract

The invention discloses a production process for brewing mature vinegar from glutinous sorghum. The production process for brewing the mature vinegar from the glutinous sorghum comprises the followingsteps: 1, preparing rhizopus bran koji; and 2, carrying out a glutinous sorghum mature vinegar production process. The glutinous sorghum is used as a raw material to brew traditional mature vinegar,traditional steaming is replaced by a process of high-temperature liquidation and low-temperature saccharification, the rhizopus bran koji is added in a saccharification process, alcoholic fermentation is carried out while saccharification, and processes of solid state acetic fermentation, smoking solid-substrate fermentation, vinegar pouring, ageing and the like follow a traditional brewing process for Shanxi mature vinegar. The problem that adhesion and caking of the glutinous sorghum are easily caused after the glutinous sorghum is steamed is solved, raw materials are decomposed fully, theflavor and quality of the mature vinegar are improved, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of mature vinegar production technology, in particular to a production technology for brewing mature vinegar with glutinous sorghum as raw material. Background technique [0002] Sorghum is the fifth largest cereal crop in the world. According to its different uses, it can be divided into edible sorghum, brewing sorghum, fodder sorghum, forage sorghum and energy sorghum. Sorghum grains contain a large amount of starch, a moderate amount of protein, and a certain amount of tannin. An appropriate amount of tannin has a certain inhibitory effect on harmful microorganisms in the fermentation process, which can increase the yield and increase the aromatic flavor. Therefore, sorghum varieties with moderate tannins are high-quality raw materials for brewing baijiu and mature Shanxi vinegar. Brewing sorghum can be divided into japonica sorghum and waxy sorghum according to its starch structure. The sorghum in nort...

Problems solved by technology

201710364580.6 "A Mechanized Brewing Process for the Production of Xiaoqu Liquor Using Waxy Sorghum as Raw Material and Its Cooling and Lowering Device" provides a mechanized production process for brewing glutinous sorghum liquor and designs a cooling and lowering device, which solves the problem of the glutinous sorghum being steamed. In addition, the literature "Research on the Effects of Different Sorghum Varieties on the Quality of Mature Vinegar" only compared the differences in physical and chemical indicators and yield of mature vinegar brewed from different varieties of sorghum, and did not mention the differences in aging vinegar brewed from glutinous sorghum. The production process of aged vinegar

At present, the research on the brewing of glutinous sorghum is all about wine products, using the method of solid-state steaming, and there is no reference to the brewing process of mature vinegar using glutinous sorghum as raw material and liquid alcohol fermentation
