Process for producing freeze-dried lactic acid bacteria powder

Abstract

The invention belongs to the technical field of microbes or enzymes and compositions thereof and specifically relates to a process for producing freeze-dried lactic acid bacteria powder. By adopting the process for producing the freeze-dried lactic acid bacteria powder, the freeze-dried powder can be applied to the food industry more conveniently. The process for producing the freeze-dried lactic acid bacteria powder comprises the following steps: 1, preparing raw materials; 2, activating lactobacillus; 3, collecting strains; and 4, freeze drying bacterial sludge.

Description

technical field [0001] The invention belongs to the technical field of microorganisms or enzymes and their compositions, in particular, relates to a production process of lactic acid bacteria freeze-dried powder. Background technique [0002] Lactic acid bacteria refers to the general term for a class of non-spore-forming, Gram-positive bacteria whose main product is lactic acid. All bacteria that can produce lactic acid bacteria from the fermentation process of glucose or lactose are collectively called lactic acid bacteria. This is a rather complex group of bacteria, which can be divided into at least 18 genera and more than 200 species. Except for a few, most of them are essential flora in the human body and have important physiological functions, which widely exist in the intestinal tract of the human body. At present, it has been confirmed by biologists at home and abroad that there is a very close direct relationship between intestinal lactic acid bacteria and health...
