Production method of high-concentration and high-quality rice vinegar

Abstract

The invention discloses a production method of high-concentration and high-quality rice vinegar. The method comprises the following steps: crushing rice by adopting a rice dry crushing technology, mixing rice flour with water and then stirring to form rice milk, and adding CaCl2 and alpha-amylase to adjust a PH value of the rice milk; liquefying the rice milk to obtain liquefied liquid, and performing alcoholic fermentation on the obtained liquefied liquid to obtain wine wash; performing pressure filtration on the wine wash to form rice wine; pumping the rice wine into an acetic acid fermentation tank, and adding acetobacter for fermenting; ultrafiltering and sterilizing vinegar. According to the production method of the high-concentration and high-quality rice vinegar, disclosed by the invention, by improving a rice wine technology, the development of a high-concentration rice vinegar fermentation technology is promoted, and industrial production of table vinegar is favorably realized; by applying a modern engineering technology theory, fluid mechanic characteristics of clear liquid fermentation materials under the condition of ventilation are researched, high-efficiency oxygen dissolving is realized, energy consumption is greatly reduced, the quality of a product is stably improved, and guidance significance for liquid vinegar manufacturers all over China is realized.

Description

technical field [0001] The invention relates to a method for producing rice vinegar, in particular to a method for producing high-quality high-quality rice vinegar. Background technique [0002] With the improvement of people's consumption level and awareness of nutrition and health care, the research on the nutritional value and health care effect of vinegar, a traditional condiment, has become more and more in-depth, which has driven the production and sales of vinegar in my country into an era of rapid development. [0003] First, vinegar has a broad market in the world as a traditional condiment. [0004] Fermented vinegar has a strong mellow aroma and long aftertaste, and has good health care effects. The development space of my country's vinegar industry is huge. With the promotion of Chinese culture in the world, the traditional Chinese food culture, which is the core of Chinese culture, is increasingly favored by people all over the world, which brings a broad deve...

AI Technical Summary

Problems solved by technology

At present, there is no precedent in the process of liquid deep fermentation vinegar production at home and abroad combined with the traditional Chinese rice wine process. This process technology has guiding significance for the production of domestic vinegar and has unique competitiveness compared with foreign vinegar production technology.
