Problems solved by technology

[0003] A preparation method of tartary buckwheat vinegar in the prior art (CN107779378A); a tartary buckwheat vinegar and its preparation method (CN104312895B) all disclose specific preparation methods of tartary buckwheat vinegar, and both use tartary buckwheat to cook and gelatinize Afterwards, tartary buckwheat vinegar is obtained by fermentation. Due to the tartary buckwheat polysaccharides contained in tartary buckwheat, the tartary buckwheat appears viscous during the fermentation process. If the water absorption and expansion of the cooking and gelatinization process are added, the volume of the supernatant after alcoholic fermentation will be reduced. Very little, increase the filtration volume and loss of tartary buckwheat vinegar mash

Abstract

The invention discloses a high-flavone tartary buckwheat beverage vinegar and its preparation method. The high-flavone tartary buckwheat beverage vinegar is prepared from tartary buckwheat through sprouting, drying, pulverizing, and extracting flavone. Flavonoids and polysaccharides are extracted from tartary buckwheat and then liquefied, saccharification and fermentation, the loss of flavonoids in tartary buckwheat fermentation is effectively avoided, adding the extracted tartary buckwheat sprout flavonoids and tartary buckwheat flavonoids into the acetic acid fermentation broth, the flavonoids content of tartary buckwheat vinegar is much higher than that of common tartary buckwheat vinegar, High flavonoid tartary buckwheat beverage vinegar is yellow-green, lustrous, sour, sweet, with tartary buckwheat unique fragrance. Drinking high flavonoid tartary buckwheat beverage vinegar can clear intestine, reduce three high levels, anti-aging and improve immunity. It can provide consumers with medicine and food vinegar products, also can promote local buckwheat production, and promote the development of tartary buckwheat industry.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to tartary buckwheat beverage vinegar with high flavonoids and a preparation method thereof. Background technique [0002] Tartary buckwheat (Fagopyrum Tataricum) is a food crop with the same origin as medicine and food. It belongs to the buckwheat genus of Polygonaceae. Accumulation and stagnation, benefit ears and soothe the nerves, relieve cough and asthma, promote blood circulation and widen the intestines, lose weight and beautify, etc. Tartary buckwheat mainly contains flavonoids, steroids, phenols and other chemical components. Among them, tartary buckwheat contains a special flavonoid substance-rutin, which can maintain the normal permeability and fragility of blood vessel walls, soften blood vessels, and promote wound healing, anti-inflammatory, anti-allergic, cough, asthma, and lower blood pressure. The role of blood lipids. At present, people pay more attention ...
