Abstract

The invention belongs to the technical field of food processing, and particularly relates to a solid-state fermentation honey Kudzu tea and a preparation method thereof. The Kudzu tea is prepared through the steps of cleaning, dicing, color protection, solid state fermentation, microwave drying, vacuum sugar infusion, baking and packaging. According to the preparation method, the content of starchin Kudzu can be reduced through solid-state fermentation, and tea soup turbidity caused by dissolving-out of brewed starch is prevented; Starch and other macromolecular substances in Kudzu can be degraded through a composite strain fermentation process, so that the release of flavonoid substances in Kudzu is improved; in addition, infusion of honey is improved through a vacuum sugar infusion process, and the taste of the traditional kudzu tea is improved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a solid fermented honey kudzu root tea and a preparation method thereof. [0002] technical background [0003] Pueraria lobata is the tuber of Pueraria genus Papilionaceae, and it is a typical medicinal and edible plant. Pueraria lobata has the effects of clearing away heat, sobering up the stomach, relieving alcohol and protecting the liver, etc. "Chinese Pharmacopoeia" stipulates that only kudzu lobata can be used as a medicinal material. The main active substances with specific effects in kudzu are mainly flavonoid aglycones and glycoside compounds. The aglycones mainly include genistein, daidzein, coumestrol, formononetin and isoliquiritigenin. Puerarin, puerarin-xyloside, genistin, daidzin, 3-methoxypuerarin, 3-hydroxypuerarin, genistein-8-C-glucoside, genistein-8- C-apirosyl-(1-6) glucoside, daidzein-4,7-diglucoside, daidzein-8-C-apirosyl-(1-6) glucoside, etc. Modern medic...
