Problems solved by technology

However, the purple sweet potato has a short maturity period and is not resistant to storage, which is the main reason why the purple sweet potato project has not been vigorously developed.
[0003] So far, there are relatively few reports on the use of purple sweet potatoes as raw materials to produce beverages in my country, mainly because purple sweet potatoes contain a lot of starch, and the beverages made by direct production are easy to separate and have poor stability.
Even if there are related literatures describing the method of enzymatic preparation of purple sweet potato juice, the problem of sedimentation during storage is still serious

Abstract

The invention discloses a purple sweet potato beverage and a preparation method thereof. The purple sweet potato beverage is composed of following raw materials: purple sweet potatoes, malic acid, water, a sweetening agent, potassium sorbate, sodium citrate, acid-resisting type sodium carboxymethylcellulose, sodium alginate, mints, vitamin C, zinc and chondroitin. The preparation method comprises the following steps: carrying out a purple sweet potato pre-treatment process; carrying out enzymolysis on mashed purple sweet potatoes; treating purple sweet potato raw juice; testing pectin and starch; clarifying; preparing; filling and sterilizing. The purple sweet potato beverage has the characteristics that the product is obtained by finely filtering by using diatomite to solve the post-turbid problem of the purple sweet potatoes; the purple sweet potato beverage has a bright purple color, is coordinated in aroma and is smooth in mouth feel; the apple juice and the purple sweet potato raw juice are blended and the apple juice can effectively neutralize the astringent taste of the purple sweet potato juice so as to improve the aroma of the purple sweet potatoes; the natural components of the purple sweet potatoes are kept; the purple sweet potato beverage is easy to store and has various functions of preventing cancers, inhibiting the cancers and the like.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a purple sweet potato drink and a preparation method thereof. Background technique [0002] Purple sweet potato is a new variety of sweet potato successfully introduced from Japan in the 1990s. Its skin is purple-black and its flesh is purple to dark purple. Purple sweet potato is a kind of crop. In the process of planting, purple sweet potato not only needs less fertilizer (farmyard manure is enough), but also has strong resistance to insect diseases. It hardly needs the application of chemical fertilizers and spraying pesticides. It is a good natural green food . It not only has the nutrition of ordinary sweet potatoes, but also is rich in anthocyanins and selenium elements. Health function. In view of its health care function and nutritional value, purple sweet potato is very popular in the international and domestic markets, and its development prospects are very...
