Sweet potato primary pulp fermented beverage and technological method

Abstract

The invention relates to a sweet potato primary pulp fermented beverage and a technological method. The technological method comprises the following steps of (1) thoroughly cleaning sweet potatoes, and soaking the cleaned sweet potatoes with a sodium hypochlorite disinfecting solution for disinfection for 20 minutes; (2) preparing a multi-functional compound solution; (3) breaking the treated sweet potatoes for the first time, adding the multi-functional compound solution, and performing filtration with a 90-120-mesh pressurized sieve so as to realize residue-pulp separation; (4) conveying sweet potato starch pulp into a standing thin layer of a clean precipitating tank, and performing natural quick precipitation on starch for 30 minutes; and (5) according to the operation, repeatedly utilizing natural precipitation or centrifuging to take primary pulp broken sweet potatoes after starch is obtained, and completing a group of processing cycles. According to the sweet potato primary pulpfermented beverage and a technological method disclosed by the invention, discharge solutions during production of sweet potato starch are in efficient bioconversion through a fermentation technique,protein and massive micro nutrients are enriched, a fresh yam primary pulp purely natural instant solid beverage is made according to a conventional beverage processing procedure, waste is turned into wealth, zero discharge of waste water during traditional starch production is realized, and economic, social and ecological benefits are considered at the same time.

Description

technical field [0001] The invention belongs to the technical field of sweet potato deep processing, and in particular relates to a sweet potato puree fermented beverage and a process method. Background technique [0002] Sweet potato is an important low-input, high-yield, drought-resistant, multi-purpose crop in China, and its output ranks first in the world. Sweet potato ranks first among the top ten health foods recommended by the World Health Organization. Its nutritional value is extremely high, and it is regarded by nutritionists as a health food with both medicine and food and the most balanced nutrition. In addition to sweet potatoes containing a lot of starch, vitamin C, vitamin B 1 , Vitamin B 2 , vitamin E, carotene, dietary fiber and a variety of amino acids (especially the rare lysine in rice noodles is very rich), it also contains minerals such as calcium, phosphorus, iron, potassium, and anti-cancer, anti-cancer mucin, Substances such as dehydroepiandroster...
