Problems solved by technology

[0004] At present, some researchers use sweet potato leaves to develop vinegar beverages and wine beverages. For example, Yue Chun and others use sweet potato leaves and tea extracts as raw materials, and use yeast to ferment tea wine (Yue Chun, Song Xinghua, He Yiping, Hu Baozhen, Wen Zhenzhen, Development and Brewing Technology of Sweet Potato Leaf Tea Wine, China Brewage, 2008 (17), 84-86), but this processing technology can not remove the green taste and astringency of sweet potato leaves well, and the fermentation process is harmful to The improvement effect of functional nutrients is not obvious

Abstract

The invention discloses a sweet potato leaf fermented beverage and a preparation method thereof. The sweet potato leaf fermented beverage comprises the following raw materials in percentage by weight: 20 to 40 percent of sweet potato leaf fermented liquid, 1 to 2 percent of honey, 4 to 6 parts of white granulated sugar, 0.05 to 0.15 percent of edible essence, and 0.015 to 0.03 percent of D-sodium erythorbate; then, water is added to make up the volume to 100 percent. According to the preparation method, fresh sweet potato leaves are dried in the sun and are subjected to high-temperature baking processing, so that the activity of enzyme in the sweet potato leaves is broken, and polyphenol compounds are prevented from enzymatic oxidation, so that the taste is guaranteed; in addition, the original taste in the sweet potato leaves can be removed, the baking fragrance is improved, and the taste is enhanced. The sweet potato leaves are fermented by utilizing traditional black tea fungi, so that nutritional ingredients of the fermented liquid are improved; the beverage prepared by using the fermented liquid has a plurality of effects of resisting cancer, nourishing the stomach and the like.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to a sweet potato leaf fermented beverage and a preparation method thereof. Background technique [0002] Kombucha is a complex mixed bacteria composed of yeast, acetic acid bacteria and lactic acid bacteria. In the traditional process, kombucha is used to ferment sugar tea water to obtain a sweet and sour natural health drink, which contains D-glucaric acid- 1,4-lactone, glucuronic acid, protein, amino acid, acetic acid, lactic acid, etc. have antibacterial, detoxifying and anticancer effects on the human body. [0003] Sweet potato is one of the four major food crops in my country. The total output and planting area of ​​sweet potato in my country rank first in the world. For a long time, what people eat is only the tubers of sweet potatoes, and only a few of the 48 billion kilograms of sweet potato leaves are used as feed, and most of them are directly discarded. Studies in recen...
