Problems solved by technology

At present, purple yam is mainly sold fresh, the processing and utilization are seriously lagging behind, and the added value of the product is not high
[0003] On the other hand, the common yam drink is made from white yam through beating, blending, cooking, and sterilization. However, due to the high starch content in the drink, it is prone to starch aging and precipitation after a long period of storage, affecting the appearance of the product. and taste
However, there is no report on the development of functional beverages rich in anthocyanins and resistant starch using purple yam as a raw material

Abstract

The invention discloses a purple yam drink and a preparation method thereof. The fresh purple yam is subjected to raw material pretreatment, color protection, beating, ultrasonic-assisted extraction of anthocyanins, autoclaving and static ultra-high pressure treatment to prepare resistant starch, blending, The purple yam beverage is prepared by nanometer homogenization, filling and high-pressure sterilization. In the present invention, after separating the anthocyanins and starch in the purple yam, the starch is used to prepare resistant starch, and then the obtained anthocyanins and resistant starch are added step by step for preparation, which can fully utilize the anthocyanins and resistant starch Physiological functions; and use nano-homogeneous technology to reduce the particle size of resistant starch, improve product stability and taste. The obtained purple yam drink has good color and stability, delicate taste, anti-cancer, anti-oxidation and other effects, low calorie, is suitable for drinking by obese people, has high added value of the product, and has a good market prospect.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a purple yam drink and a preparation method thereof. Background technique [0002] Purple yam, as a high-quality yam, has been planted on a large scale in Zhejiang, Jiangxi, Fujian and other provinces in my country. Its meat is fresh and tender, and it is rich in nutrition. Compared with ordinary yams, purple yams are rich in anthocyanins, which have multiple functions such as lowering blood lipids, regulating blood pressure, preventing and fighting cancer, anti-aging, and beauty. At present, purple yam is mainly sold fresh, and its processing and utilization are seriously lagging behind, and the added value of the product is not high. [0003] On the other hand, the common yam drink is made from white yam through beating, blending, cooking, and sterilization. However, due to the high starch content in the drink, it is prone to starch aging and precipitation after a lo...
