Drink containing black tea fungi and method for manufacturing drink

Abstract

The invention discloses a drink containing black tea fungi. The mass content of total soluble sugar in the drink is higher than 3%, and the mass content of reducing sugar in the drink is lower than 0.5%. The method includes steps of (1), weighing tea leaves, adding the tea leaves in water, boiling the water, filtering tea residues, adding a finished soluble dietary fiber product into tea soup while the tea soup is hot, dissolving the finished soluble dietary fiber product to obtain to-be-fermented solution, alternately, initially processing natural plants containing soluble dietary fibers to obtain aqueous solution containing the soluble dietary fibers, then weighing tea leaves, adding the tea leaves into the aqueous solution containing the soluble dietary fibers, boiling the aqueous solution, and filtering tea residues to obtain to-be-fermented solution; (2), cooling the to-be-fermented solution obtained in the step (1), and inoculating black tea strains in the to-be-fermented solution; and (3), performing static culture or dynamic culture for the solution with the black tea strains to obtain the drink containing the fungi. The soluble dietary fibers are utilized, particularly, inulin is used as a carbon source for manufacturing the drink containing the black tea fungi, and the drink does not contain the reducing sugar or only contains a small quantity of the reducing sugar, and accordingly can be drunk by patients suffering from diabetes mellitus.

Description

[0001] technical field [0002] The invention relates to the processing and manufacture of a fermented beverage, in particular to a kombucha beverage and a preparation method thereof. Background technique [0003] Kombucha is a sour and sweet drink made from sugar tea water and fermented by microorganisms such as lactic acid bacteria, yeast, and acetic acid bacteria. Traditional kombucha uses glucose and sucrose as carbon sources to ferment the beverage. It often contains a certain amount of residual sugar and reducing sugar formed by microbial metabolism. These sugars are metabolized by insulin and easily cause blood sugar concentration to rise, so it is not suitable for diabetics to drink. [0004] Soluble dietary fiber mainly exists in: sea cabbage, seaweed Eucheuma, kelp, seaweed, konjac, mushrooms, yam, fruit peels and vegetables. Clinical proof: eating 50-100 grams of soluble dietary fiber per meal can significantly reduce the fluctuation of blood sugar after meals, w...
