Abstract

The invention discloses probiotic fermented milk with dragon fruit seed proteins and a preparation method thereof; deoiled dragon fruit seed meal is used as a main material subjected to mixed fermentation with Aspergillus oryzae and Lactobacillus plantarum to obtain protein milk, and a preparation method of the milk is provided; the preparation method comprises: 1) preparing dragon fruit seed protein pulp; 2) blending the dragon fruit seed protein pulp; 3) preparing a leaven; 4) inoculating and fermenting; since the deoiled dragon fruit seed meal as raw material, byproducts are reused and nutritional added value of the dragon fruit seed meal is increased; the milk is prepared by direct fermentation of microorganisms, and implementing is easy; the milk has unique flavor, is agreeably sour and sweet, has rich nutrients and the active ingredients such as Upsilon-aminobutyric acid, and has good nutritional, economic and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of value-added utilization of agricultural and sideline products and fermented food, and specifically relates to dragon fruit seed protein probiotic fermented milk and a preparation method thereof. Background technique [0002] Dragon fruit (Hylocereus undulatus), also known as red dragon fruit, green dragon fruit, celestial honey fruit, lover fruit, etc., is a cultivated crop for the fruit of the cactus family.
