Abstract

The invention discloses blood fat-reducing probiotic fermented milk and a preparation method thereof. The ingredients of the fermented milk comprise material liquid, probiotics and mannase, wherein the material liquid is prepared from raw milk, tea powder, grape seed extract, pawpaw pulp, konjaku flour and molasses, and the probiotics is selected from lactobacillus plantarum and/or lactobacillus casei. The preparation method comprises the steps that the material liquid is subjected to homogeneous sterilization and then inoculated with the probiotics and the mannase, standing fermentation is performed at the temperature of 37 DEG C-39 DEG C until the titration acidity is 70-95oT, and the fermented milk is obtained; the fermented milk is cooled and filled, and after-ripening is performed for 12-24 hours in an environment at the temperature of 2 DEG C-10 DEG C. Accordingly, the technical problems that the lactobacillus casei is slow in growth and propagation in the raw milk, and the lactobacillus plantarum almost cannot achieve fermenting and curding alone in the pure raw milk are solved, the blended materials are screened through fermentation condition optimization, the probiotics and all the ingredients of the material liquid achieve the synergistic effect, and therefore the fermenting time is greatly shortened; in addition, the probiotics content is increased, and therefore the blood fat reducing effect of the final product is excellent.

Description

technical field [0001] The invention relates to the technical field of dairy product production, in particular to fermented milk with probiotics for reducing blood fat and a preparation method thereof. Background technique [0002] Blood lipids are the general term for neutral fats (triglycerides and cholesterol) and lipids (phospholipids, glycolipids, sterols, steroids) in plasma. In recent years, the incidence of lipid metabolism disease has been increasing year by year, and it is becoming younger. It has become one of the main "killers" that endanger human health and life. Hyperlipidemia refers to abnormal fat metabolism or operation in the human body, which makes one or several lipids in the plasma higher than the normal range, which can be manifested as hypercholesterolemia, hypertriglyceridemia or both. Hyperlipidemia can be the concentration of one or more blood lipid components in plasma exceeding the upper limit of normal values ​​(such as high cholesterol, high tr...
