The beverage of the present invention adopts fresh purple sweet potatoes with skins as production raw materials, does not contain any preservatives and other pigment additives, is sweet and sour, delicious and nutritious, and is suitable for drinking by consumers including fat-phobic people, obesity patients and diabetic patients; and The production method is simple, the production cost is low, and it is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of food and drink, and in particular relates to a lactic acid drink and a production method thereof. Background technique [0002] Purple sweet potato, also known as black sweet potato, is a vine of the genus Ipomoea batata in the Convolvulaceae family. It is brown or black in appearance and purple in section. Purple sweet potato is rich in various amino acids and trace elements such as zinc, iron, copper, manganese, calcium and selenium, among which the content of lysine, copper, manganese, potassium and zinc is 3-5 times that of ordinary sweet potatoes, especially iodine The content of selenium and active selenium (0.016-0.018mg / kg) is more than 20 times that of common varieties, ranking first in food. In addition, the content of calcium and zinc is more than ten times higher than that of wheat and corn. Purple sweet potato is also rich in various nutrients, including 0.9% water-soluble dietary fiber, 2....
