Problems solved by technology

[0003] Existing patents for the development of Rosa roxburghii beverages are all limited to squeezed juice, pickled for canning and simple compound fermentation, and a large amount of stabilizers and thickeners are added in the production process to cover up Rosa roxburghii as a "vitamin". The natural value of "King of C" limits the selling price of its finished products; Rosa roxburghii itself has high tannin content, which is a kind of water-soluble phenolic compound, which is astringent in the mouth and easily soluble in water. The problem that is difficult to remove in beverage processing and affects the taste of the finished product. At present, the methods commonly used to remove the bitterness of fruit juice include: embedding method, adding bitterness inhibitor and microbial method

Abstract

The invention relates to the field of processing of foods and beverages, in particular to a low-tannin fermented rosa roxbunghii beverage and a preparation method thereof. The low-tannin fermented rosa roxbunghii beverage provided by the invention comprises the following component in percentage of rosa roxbunghii original juice of which the addition amount is 30-50%, cane sugar of which the addition amount is 5-10%, protein powder of which the addition amount is 0.05-0.3%, kefir microbial populations of which the inoculum concentration is 0.005-0.02%, calcium carbonate of which the addition amount is 6% and the balance of water. The low-tannin fermented rosa roxbunghii beverage disclosed by the invention has the characteristics of being mellow and brisk in mouth feel, moderate in sour andsweet degree and good in organoleptic quality; by the method, the tannin content in rosa roxbunghii is effectively reduced, and the problems that tannin is difficult to remove and influences the mouthfeel of made products during beverage processing are effectively solved; and besides, the tannin is utilized as a microbial carbon source, along with prolonging of fermentation, the tannin content iscontinuously reduced, and the tannin content is reduced by 3-10% compared with that of an ordinary strain fermented rosa roxbunghii beverage.

Description

technical field [0001] The invention belongs to the field of food and beverage, and in particular relates to a low-tannin fermented prickly pear beverage and a preparation method thereof. Background technique [0002] White sour soup prickly pear (Rosa roxbunghii), scientific name reeling flower, send spring flowers, pear pomegranate, wood pear and so on. It is a perennial deciduous shrub belonging to the Rosaceae family. Rosa roxburghii has a particularly strong aromatic smell and a sweet and sour taste with a slightly astringent taste. Its nutritional components are mainly vitamin C and superoxide dismutase. Related studies have shown that the content of various nutrients in the fresh fruit of Rosa roxburghii is: the content of vitamin C is 2087.8mg / 100g, the content of vitamin E is 235mg / 100g, and the content of vitamin P is 5900mg / 100g. 100g, superoxide dismutase is 2100 activity units. The Vc, Vp and SOD contained in thorn pear are the highest among all fruits, so th...
