Abstract

The invention discloses a nutritional and healthcare yam beverage and a preparation method. 1000 parts of yam beverage is prepared from the following raw materials in parts by weight: 25-60 parts of yam, 2-50 parts of pear, 20-80 parts of tea polyphenol, 683-901 parts of water, 15-40 parts of chrysanthemum, 1-7 parts of stabilizer, 16-65 parts of sweetening agent and 2-15 parts of sour agent. The production method comprises the steps as follows: preprocessing the raw materials; pulping; mixing; carrying out enzyme reaction; blending; homogenizing; filling; sterilizing; and checking. The yam beverage is sour, sweet, tasty, unique in flavor, rich in nutrition and rich in theaflavin, and has the effects of lowering blood fat and preventing cardiovascular and cerebrovascular diseases.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a nutritional and health-care yam drink and a preparation method thereof. Background technique [0002] Yam is the general term for the underground tubers of Dioscorea yam, mainly distributed in tropical and subtropical regions. There are more than 600 species in the world, and there are more than 90 species in my country. Yam has high nutritional value and is rich in active health-care ingredients such as various essential amino acids, vitamins, polysaccharides, saponins, and flavonoids. The traditional processing of Chinese yam is mainly based on traditional Chinese medicine or tonics. In recent years, yam powder, refined powder, yam beverage, canned food, preserved fruit and other foods have appeared, and the processing scale and market share have continued to increase. However, there is a problem of color protection in yam processing. If the conditions are not prope...
