Abstract

The invention discloses a preparation method of banana-goat milk composite yoghourt. The method is particularly implemented according to the following steps: preparing banana pulp, preparing goat milk, performing inoculation and fermentation, and preparing the product as the banana-goat milk composite yoghourt. The quality of the banana-goat milk composite yoghourt is influenced by the following factors in a gradually reduced order: the amount of goat milk powder, the amount of banana juice, the amount of saccharose and the amount of strains. The concentration of the substrates positively influences the mellow degree of the yoghourt. In particular, when the concentration of the substrates is 14 percent of the goat milk powder, 0.3 percent of strains, 8 percent of saccharose and 2 percent of banana juice, and the substrates are filled and fermented and cultured at 42 DEG C for 6 h, the yoghourt with excellent flavor and better quality can be produced.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for preparing banana compound goat's milk yoghurt. Background technique [0002] Yogurt has always been a food favored by humans for a long time. Its sweet and sour taste, delicate taste, and fresh and sweet taste are deeply loved by men, women and children. The most important thing is the nutritional value of yogurt. Yogurt is a milk beverage with special flavor that is fermented with raw milk, fresh milk or dairy products as the main raw material and added with lactic acid bacteria or yeast. During the fermentation process of yogurt, about 20% of sugar and protein in milk are hydrolyzed into small molecules (such as galactose and lactic acid, small peptide chains and amino acids, etc.). The fat content in milk is generally 3-5%. After fermentation, the fatty acid in yogurt can be doubled compared with raw milk. These changes make yogurt easier t...
