Abstract

The invention provides active lactobacillus drink rich in conjugated linoleic acid and a preparation method of the active lactobacillus drink. The method provided by the invention comprises the following steps of: mixing the linoleic acid with the oleophylic stearic acid direactive glyceride to prepare the linoleic acid emulsion, wherein the oleophylic stearic acid direactive glyceride is 1%-2% of the linoleic acid by weight; adding the linoleic acid emulsion into raw milk, wherein the additive amount is 1%-5%; then, homogenizing, sterilizing and cooling to 40-44 DEG C, adding the fermentation strains containing the lactobacillus plantarum, fermenting at 40-44 DEG C for 6-10 hours, and stopping the fermentation when the pH value is about 3.9-4.1 to obtain the acidophilus milk bases; and diluting the acidophilus milk bases to obtain the active lactobacillus drink rich in the conjugated linoleic acid. In the method, the technological conditions are rationally controlled, so that the prepared active lactobacillus drink rich in the conjugated linoleic acid has special flavor, fresh taste and excellent stability.

Description

technical field [0001] The present invention relates to an active lactic acid bacteria beverage and a preparation method thereof, in particular to a method for preparing an active lactic acid bacteria beverage rich in conjugated linoleic acid by a biotransformation method, and the prepared conjugated linoleic acid-rich beverage The active lactic acid bacteria beverage belongs to the field of fermented milk product processing. Background technique [0002] Conjugated Linoleic Acid (CLA) is a mixture of a series of octadecadienoic acids (Octadecadienoic acid) containing conjugated double bonds. A general term for octadecadienoic acid geometric isomers with conjugated unsaturated double bonds at different positions. Conjugated linoleic acid can remove free radicals in the human body, enhance the body's antioxidant capacity and immune capacity, regulate blood cholesterol and triglyceride levels, promote growth and development, promote fat oxidation and decomposition, prevent at...
