Abstract

The invention relates to a dried pit mud functional bacteria protectant. The dried pit mud functional bacteria protectant comprises sorbitan monostearate, trehalose, glycerin, D-sodium isoascorbiate and the balance water. The invention further provides a preparation method of the dried pit mud functional bacteria protectant and application of the dried pit mud functional bacteria protectant for preparing dried pit mud functional bacteria. Through proportioning of the sorbitan monostearate, trehalose, glycerin and the D-sodium isoascorbiate, cell viability of the dried active pit mud functional bacteria can be increased to 82-89%, survival rate of the dried active pit mud functional bacteria is increased to 80-85%, capability of the dried active pit mud functional bacteria for producing ethyl caproate is improved remarkably, and the shortcoming that existing microorganism protectants are not suitable for the functional bacteria in pit mud is solved.

Description

technical field [0001] The invention relates to a functional bacteria protective agent for dehydrated pit mud and an application thereof, belonging to the technical field of microbial products and liquor brewing. Background technique [0002] Dehydrated cellar mud functional bacteria are made by caproic acid bacteria, monascus and aromatic yeast, adding protective agent and forming agent, extruding, granulating, drying and dehydrating. The dehydration active cellar mud functional bacteria are mainly used in the production of Luzhou-flavor liquor, which can make the taste of the liquor produced in the new cellar producing Luzhou-flavor liquor the same as that of the liquor produced in the old cellar, and produce high-quality liquor. The living cells in the dehydration active pit mud functional bacteria will partially lose their activity during drying, dehydration, storage, and rehydration, which will affect the quality of the product. The protective agent can reduce the loss ...
