Abstract

Potato yoghourt and a making method thereof are disclosed. 40-60% of potato juice is creatively added into yoghourt, and lactobacillus bulgaricus and streptococcus thermophilus are used in cooperation for fermentation. On the basis of controlling the ratio of the materials and the making method, the potato yoghourt with rich nutrients, moderate sweetness and palatable sour taste is prepared.

Description

technical field [0001] The invention relates to the field of fermented beverages, in particular to a potato yoghurt and a preparation method thereof. Background technique [0002] The use of lactic acid fermentation is one of the earliest methods of food processing and preservation. In recent years, the use of lactic acid bacteria has been continuously developed from traditional dairy products to the application of other food raw materials, but there are still few reports and studies on lactic acid fermentation using potatoes as raw materials. Lactic acid bacteria can maintain normal flora in animals, regulate the physiological functions of organisms and enhance immunity, and produce a large amount of organic acids such as lactic acid, various amino acids and vitamins during the fermentation process. [0003] Yogurt made from fermented milk is easy to digest and absorb. During the fermentation process, about 20% of the sugar and protein in the milk are decomposed into small...
