Low-sugar brown lactobacillus drink and preparation method thereof

Abstract

The invention discloses a low-sugar brown lactobacillus drink and a preparation method thereof. The preparation method comprises the following steps: (1) mixing raw milk with lactase, and standing to obtain mixed liquid; (2) producing Maillard reaction of the mixed solution to obtain browned liquid; (3) cooling the browned liquid, fermenting, and cooling to obtain a fermented milk base material; (4) mixing sugar water liquid with the fermented milk base material, and homogenizing to obtain the low-sugar brown lactobacillus drink, wherein the sugar water liquid is prepared by mixing water with an additive A, sterilizing and cooling. According to the preparation method, lactose is decomposed by a bio-enzyme technology, and the effect of the Maillard reaction can be achieved without addition of reducing sugar, such as exogenous glucose; the low-sugar brown lactobacillus drink is relatively natural and mild in mouth feel, and an emulsifier can be reduced and even is no longer used according to the actual situation.

Description

technical field

[0001] The invention belongs to the field of fermented dairy product processing, and specifically relates to a low-sugar brown lactic acid bacteria drink and a preparation method thereof. Background technique

[0002] Milk is recognized as a very nutritious food all over the world, rich in protein, fat, lactose and minerals. The yogurt product obtained by adding bacteria to milk as a substrate, on the one hand, the added live bacteria are beneficial to intestinal peristalsis and immunity, on the other hand, on the basis of the original nutritional value of milk, part of the protein in milk It is decomposed into peptides and amino acids, and part of the fat and lactose is also decomposed into smaller compounds, which are easier to be absorbed by the body.

[0003] Fermented lactic acid bacteria drinks are formulated on the basis of fermented milk by adding an appropriate amount of white sugar, stabilizers and water. In recent years, Yakult and other flavored...
