Embodiment 1
[0126] The composition of the compound medium for Lactobacillus acidophilus fermentation is:
[0127] 10% licorice decoction filtrate 10000ml
[0128] Polyvalent peptone 100g
[0129] Preparation of compound medium for Lactobacillus acidophilus fermentation:
[0130] (1) Preparation of 10% licorice decoction filtrate (GJY):
[0131] a. Select dry licorice rhizomes or decoction pieces without mildew, wash with water, remove impurities, and dry.
[0132] b. Weigh 1000 g of licorice, and physically pulverize the licorice by mechanical pulverization until a fine powder with an average particle size of 100-150 μm is obtained.
[0133]c. After the licorice fine powder is frozen at a low temperature to the critical point of fragmentation, energy pulverization is carried out by means of airflow pulverization until an ultrafine powder with an average particle size of 5-25 μm is obtained.
