A kind of synbiotics liquid goat milk beverage and preparation method thereof

Abstract

The invention discloses a synbiotic liquid goat's milk drink and a preparation method thereof, comprising 35-50 parts of synbiotic sour goat's milk, 5-10 parts of sucrose, and 0.15-0.5 parts of a stabilizer in parts by mass; 38-60 parts of water; the synbiotic yogurt goat milk is to add 2-5.5% probiotics and 0.1-2.5% prebiotics by mass to goat milk or goat milk reconstituted milk, and carry out anaerobic treatment for 5-18 hours. fermentation. Synbiotic sour goat milk is fermented with a probiotic after adding oligosaccharides and prebiotics; probiotics have a great effect on improving the microenvironment of probiotics in the human intestinal tract and promoting human health; adding oligosaccharides promotes probiotics The growth of goat milk not only retains the nutritional value and unique flavor of goat milk, but also strengthens the functional properties of oligosaccharides.

Description

technical field

[0001] The invention belongs to the technical field of functional goat milk products, and relates to a synbiotic liquid goat milk beverage and a preparation method thereof. Background technique

[0002] Goat milk is regarded as a fine product among dairy products due to its advantages such as rich nutrition and easy absorption. However, due to the inherent smell of goat milk, the development of goat milk is largely limited. At present, the production scale of goat milk in my country is small, the production technology is backward, the product is single, the added value is low, and the market competitiveness is lacking.

[0003] Probiotics refer to live microbial preparations that can promote the ecological balance of intestinal flora and have beneficial effects on the host. The probiotics published in my country that can be used in health food are mainly Lactobacillus and Bifidobacterium. The lactic acid bacteria used in yogurt and probiotics in Japan, Eur...
