Abstract

The invention discloses a bifidobacterium freezing concentration starter and a preparation method thereof. The preparation method can solve the problems of difficult culturing of the bifidobacterium, lower activity of the starter and short preservation period. The preparation method includes: culturing a strain activation tube, culturing the strain of first grade by a triangle bottle, culturing the strain of second grade with a seed pot, culturing in a fermentation pot, concentrically collecting the strain, adding a protective agent, packaging in vacuum and storing in a freezing way. The starter is mainly characterized by high live bacteria content, longer shelf life, less inoculation dosage, being capable of stabilizing each batch of fermented dairy products, preventing the strain from degradation and pollution as well as greatly improving the working production rate and the product quality of the fermented dairy product industry. Compared with the starter prepared by the vacuum freezing drying method, the freezing concentration starter prepared by the invention has the advantages of simple method, less device investment, lower cost and easy realizing.

Description

technical field

[0001] The invention relates to a bifidobacteria freeze-concentrated starter and a preparation method thereof. Background technique

[0002] Bifidobacteria are normal physiological bacteria in the human body. They colonize the intestinal tract and are the dominant flora in the intestinal tract. The number of bifidobacteria is closely related to human health. Sexual beneficial bacteria. The main physiological functions of bifidobacteria are: 1. biological barrier and biological antagonism; 2. enhancing immunity and anti-tumor effect; 3. nutritional effect; 4. inhibiting the production of endotoxin; With the increase of age, the influence of environmental pollution and the use of antibiotics, the number of bacteria in the human intestinal tract gradually decreases, resulting in the destruction of the micro-ecological balance in the intestinal tract, leading to the occurrence of various diseases and aging.

[0003] The most direct way to replenish bifidobacter...
