Active probiotic solid beverage and preparation method thereof

Abstract

The invention discloses an active probiotic solid beverage and a preparation method thereof. The active probiotic solid beverage comprises the following components in percentage by mass: 4%-10% of probiotics, 40%-46% of prebiotics, 17%-20% of maltodextrin and the balance of skimmed milk powder. The prebiotics fructo-oligosaccharide, isomaltooligosacharide and inulin have an obvious proliferation effect on five kinds of beneficial bacteria such as streptococcus thermophilus, lactobacillus acidophilus, lactobacillus plantarum, lactobacillus rhamnosus and lactobacillus bulgaricus which are synergistic and beneficial in the gastrointestinal tract of a human body, and the number of active probiotics and the stability of the viable count of the product in the shelf life are ensured. The probiotic solid beverage prepared by compounding prebiotics and probiotic powder and adding specific auxiliary materials not only can promote the growth of beneficial bacteria in intestinal tracts and reduce the inactivation rate of the probiotics, but also can generate metabolites capable of protecting intestinal functions, and has the effects of meal replacement and nutrition.

Description

technical field [0001] The invention relates to the field of food processing, in particular to an active probiotic solid beverage and a preparation method thereof.
