Abstract

The invention discloses a black tea fungus jelly and a preparation method thereof. The jelly comprises the following raw materials by weight percent: 15-30% of black tea fungus fermentation broth, 0.01-0.05% of black tea powder, 0.8-1.4% of gelling agent, 10-18% of white granulated sugar, defined amount of sour agents, defined amount of stabilizing agent, defined amount of food preservatives and 45-75% of water. The jelly and the preparation method have the following beneficial effects: the traditional special resource, black tea fungus, in China is utilized and the black tea fungus fermentation broth with various functions is added to the ingredients of the jelly; the preparation process is simple and practicable; the production cost is low; the thermally sensitive beneficial ingredientsin the tea extracts, black tea fungus fermentation broth and black tea powder can be effectively prevented from being destroyed; and the prepared jelly has unique fermentation flavor of the black teafungus, rich nutrition, natural color, good elasticity and ductility and sweet and sour taste, is smooth and delicate, has the health care functions of cleaning intestines and stomachs and helping digestion and has better market prospect.

Description

technical field [0001] The invention relates to the field of nutritional food, in particular to a kombucha jelly and a preparation method thereof. Background technique [0002] Jelly is deeply loved by children and young people for its smooth taste and pleasant taste, and has become a popular snack food today. But most of the currently commercially available jellies are made from gelling agents, sweeteners, essences and pigments, etc., which not only have low nutritional value and limited health care functions, but also have added excessive artificial pigments and preservatives. There may also be adverse effects on the health of consumers. [0003] Kombucha is a mixed bacteria system composed of yeast, acetic acid bacteria and lactic acid bacteria. It is used to microbiologically ferment raw sugar tea water to obtain a pure natural health drink with a sweet and sour taste. Kombucha fermented liquid contains glucose, fructose, polysaccharide, lactic acid, acetic acid, gluco...
