Process for producing probiotic fermented milk

Abstract

The invention discloses a process for producing probiotic fermented milk. The process is characterized by including the following steps: (1) probiotic mother culture fermentation: first-time propagation, second-time propagation, high-density cultivation and probiotic fermentation, (2) raw milk sterilization: firstly taking powder and water with the proportion of 1:5 to be mixed, heating the mixture to be at the temperature of 80-85DEG C, adding 0.05-0.25 part of alpha amylases, heating the mixture to be at the temperature of 90-95DEG C, preserving the temperature for 20 minutes, carrying out pasteurization, and cooling, (3) inoculation, (4) fermentation: CIP cleaning and high-pressure homogeneity, and (5) filling: automatic filling. According to the process, the CIP cleaning process, the high pressure homogeneity process, the superhigh temperature instantaneous sterilization process and the automatic filling process are adopted, the viable count in a probiotic fermented milk product is not lower than 106CFU / mL, flow line production of a whole process from raw materials to finished products is achieved, and cholesterol is reduced. A new robiotic milk product and an anti-hypertension probiotic milk product can be produced according to the process.

Description

technical field [0001] The invention relates to a production process of probiotic fermented milk. Background technique [0002] Studies have shown that probiotics can adjust the balance of human intestinal flora, increase the number of probiotics in the intestinal tract, and treat intestinal flora imbalance; promote the body's digestion and absorption of food; improve the body's immunity and enhance human immune function; absorb carcinogens And reduce the concentration of carcinogenic mutants and the activity of certain enzymes in feces, inhibit and slow down the incidence of tumors; reduce the level of toxins in the human body, help liver cells grow and protect the liver; probiotic fermentation products (including bacteria ) has antihypertensive and / or regulating blood lipid concentration, lowering the level of cholesterol combined with low-density lipoprotein in serum, probiotic fermentation can also produce a variety of physiologically active small peptides that are benef...
