Problems solved by technology

In the production process of soft liquor, the microorganisms in the natural environment are enriched, and traditional Daqu and Xiaoqu are added for wine production. However, the types and quantities of microorganisms in natural conditions are very limited. Microbial enrichment cannot fully meet the needs of brewing production, thus limiting the taste of soft liquor mainly based on taste

Abstract

The invention discloses an aspergillus oryzae functional enzyme preparation and application thereof, and belongs to the technical field of white wine brewing. The aspergillus oryzae functional enzyme preparation is prepared by performing solid state fermentation and drying on an aspergillus oryzae strain. In the white wine brewing process, the aspergillus oryzae functional enzyme preparation is additionally added into cooked and gelatinized main raw materials to be fermented. As the aspergillus oryzae functional enzyme preparation is added to ferment the raw materials, the process is simple and controllable, the wine yield and the high-quality rate of white wine can be effectively increased, the quality of the white wine is improved, and social and economic benefits are achieved.

Description

technical field [0001] The invention relates to an aspergillus oryzae functional enzyme preparation and application thereof, belonging to the technical field of liquor brewing. Background technique [0002] Chinese liquor has a history of thousands of years in our country. It is loved by consumers for its elegant appearance, special aroma and rich taste. Enzyme is very important in liquor brewing. The enzyme system for liquor brewing is mainly provided by Daqu. It has been reported in the literature that the production and aroma of liquor can be improved by adding industrial enzyme preparations. As the country pays more and more attention to food safety, the use of industrialized production of enzyme preparations will bring corresponding food safety risks. [0003] Soft liquor is a new category of liquor developed by Jianghuai Baijiu on the basis of inheriting the strong-flavor liquor. It breaks the traditional method of "fragrance" to shape liquor, and develops a new era ...
