Colloidal suspension for adding probiotics in acidic milk drinks and method for producing acidic milk drinks containing probiotics

Abstract

The invention relates to the field of liquid milk, concretely, the invention relates to a colloid fluid suspension used for adding probiotics in acidic milk beverage and a method for producing probiotics-containing acidic milk beverage. According to the invention, the colloid fluid suspension used for adding aseptic probiotics in acidic milk beverage comprises the following components by weight, 1-5 parts of sugar and 0.1-0.6 parts of suspending agent; wherein the suspending agent comprises gellan gum, xanthan gum and acid resistant CMC according to a ratio of 1: 2 :3; 0.3-0.5 part of lactic acid and balance of water, wherein the pH value is 4.3-4.5. The method of the invention for producing probiotics-containing acidic milk beverage comprises the following steps: suspending aseptic embedded probiotics particles on the colloid fluid suspension, then ensuring asepsis and adding. According to the invention, probiotics stably survived in aseptic acidic milk beverage at normal temperaturecan be realized by the colloid fluid suspension, and probiotics is not easy to breed and grow in product shelf period, wherein the probiotics quantity in product is more than 107 cf umL, simultaneously the quality of the product can not be influenced, so that the active probiotics existed in the milk beverage product at normal temperature can be realized.

Description

technical field

[0001] The invention relates to the field of liquid milk, in particular, the invention relates to a colloidal suspension used for adding probiotics to acid milk drinks and a method for producing acid milk drinks containing probiotics. Background technique

[0002] There are two types of acidic milk drinks currently on the market: formulated milk drinks and fermented milk drinks. Formulated milk-containing beverages do not contain probiotics, while fermented milk-containing beverages are divided into sterilized (non-live bacteria) milk drinks and non-sterilized (live bacteria) milk drinks according to whether they are sterilized. Sterilized (non-viable) milk drinks do not contain active probiotics. Unsterilized fermented milk beverages are directly prepared from fermented milk. Since they are not sterilized after the preparation, although other raw materials are dissolved and mixed and then sterilized, the product will be polluted by microorganisms during the...
