Abstract

The invention relates to the field of food processing and the field of biotechnology, and discloses a lactic acid bacteria stabilizer, a lactic acid bacteria beverage and a preparation method. The lactic acid bacteria stabilizer comprises low-ester pectin, medium-substitution starch phosphate, tragacanth, a metal ion regulator, a carbon source, an antioxidant and an osmotic pressure regulator. Thepreparation method of the lactic acid bacteria stabilizer comprises the following steps: firstly, adding low-ester pectin and tragacanth into water at the temperature of 75-85 DEG C, heating to 90-100 DEG C, and stirring for dissolving to obtain a mixed solution; and cooling the mixed solution to 30-40 DEG C, and adding other components to obtain the lactic acid bacteria stabilizer. The low-esterpectin, the medium-substitution starch phosphate and the tragacanth are mixed to form a copolymer, the lactic acid bacteria can be partially embedded and used in the lactic acid bacteria beverage, the stability of the lactic acid bacteria beverage can be improved, the storage stability of the lactic acid bacteria can be improved, and the survival time of the lactic acid bacteria can be prolonged.

Description

technical field [0001] The invention relates to the field of food processing and the field of biotechnology, more specifically, to a lactic acid bacteria beverage additive, a lactic acid bacteria beverage and a preparation method. Background technique [0002] Lactic acid bacteria is a general term for a class of bacteria that can convert fermentable sugars into lactic acid. Lactic acid bacteria also widely exist in human and animal intestines, many foods, materials and a few clinical samples, which can not only improve the nutritional value of food, improve food flavor, improve food preservation and added value, but also the special physiological activity and nutritional function of lactic acid bacteria , is attracting increasing attention. A large number of studies have shown that lactic acid bacteria can regulate the normal flora of the gastrointestinal tract of the body, maintain micro-ecological balance, improve food digestibility and biological value, reduce serum cho...
