Abstract

The invention discloses a method for improving dried orange peel flavonoid content by using aspergillus flavus. According to the method, dried orange peel is processed by using the aspergillus flavus. By using the aspergillus flavus to process the dried orange peel, total flavonoid content and content of four kinds of flavonoid of naringin, aurantiamarin, nobiletin and tangeretin in the dried orange peel can be improved in a short time, the increase of antioxidant activity of the dried orange peel can be promoted, and a good application prospect is realized.

Description

technical field [0001] The invention relates to a method for increasing the flavonoid content of tangerine peel by using Aspergillus flavus. Background technique [0002] Tangerine peel is the dry and mature peel of Citrus reticulata Blanco and its cultivars of the Rutaceae plant. It was first recorded in "Shen Nong's Materia Medica" and listed as top grade. It is commonly used for both medicine and food, with a wide range of uses and a large dosage. Tangerine peel is fragrant and slightly bitter. It is mainly used to treat symptoms such as distension and fullness in the abdomen, lack of appetite, vomiting and diarrhea, and cough with excessive phlegm. Pharmacological studies have shown that tangerine peel has good medicinal value in cardiovascular system, immunity, anti-oxidation and anti-tumor. [0003] The chemical composition of tangerine peel is mainly based on flavonoids, and also contains substances such as volatile oil, limonoids, and alkaloids. Flavonoids have th...
