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 beverage and a preparation method thereof. The purple yam beverage is obtained through the following steps: pretreating raw materials namely fresh purple yam, performing color protection, mashing the purple yam after color protection, extracting anthocyan assisted by ultrasonic waves, pressing and heating the purple yam without the anthocyan, treating the heated purple yam under a static state and extra-high pressure for preparing resistant starch, compounding the resistant starch and the anthocyan so as to obtain a mixture, homogenizing the compounded mixture with nanometer, filling the homogenized mixture, and sterilizing the filled mixture at high pressure so as to obtain the purple yam beverage. According to the purple yam beverage and the preparation method thereof disclosed by the invention, after the anthocyan and the starch in the purple yam are separated, the starch is prepared into the resistant starch, and then the anthocyan and the resistant starch are added step by step and are prepared, so that physiological functions of the anthocyan and the resistant starch can be fully utilized; besides, a nanometer homogenizing technology is utilized, so that the particle size of the resistant starch is decreased, and the stability and the mouth feel of products are improved; the prepared purple yam beverage is good in color and stability, is fine and smooth in mouth feel, has the efficacies of resisting cancer, resisting oxidation and the like, is low in heat, is suitable for obesity crowds to drink, is high in added value of products and is good in market prospects.

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...
