Standardization process of mechanized production of Shanxi mature vinegar based on haccp system

Abstract

The invention discloses a standardized process for the mechanized production of Shanxi mature vinegar based on the HACCP system. The sorghum whose residual and heavy metal indicators meet the standard; after removing impurities and dust, crush it into 40~55 mesh sorghum flour, add it into the stainless steel liquefaction tank with pre-added water according to the grain-water ratio of 1:3.8~1:4.5, and stir while adding , and then boiled and steamed grains for 1 hour, cooled to 28~32°C, the initial starch content of alcohol fermentation was 13~15%; after adding crushed Daqu, it was sent into a temperature-controlled alcohol fermentation tank with a temperature of 28°C. The method of the invention standardizes the technical parameters of the mechanized brewing of Shanxi mature vinegar, thereby establishing a perfect HACCP system and the internal control quality standard of Shanxi mature vinegar enterprises.

Description

technical field [0001] The invention relates to the technical field of vinegar production, in particular to a standardized process for the mechanized production of Shanxi mature vinegar. Background technique [0002] Shanxi Mature Vinegar uses sorghum as the main raw material, bran, rice husk and rice husk as auxiliary materials, and Daqu made with barley and peas according to traditional techniques as a saccharification starter. It is fermented by high-temperature solid-state acetic acid, then fermented with smoked grains, poured with vinegar, and aged for more than 12 months. The color of the product is reddish brown, the aroma is harmonious, the taste is sour, the taste is mellow, the taste is sweet and sour, and the aftertaste is long. [0003] The vinegar brewed by the traditional solid-state fermentation process has complete color, aroma and taste, no sharp sour taste, comfortable entrance, and excellent flavor, but the traditional solid-state vinegar brewing process ...
