| titleOfInvention | Extraction process of dihydromyricetin in vine tea and preparation process of vine tea functional beverage |
| abstract | The invention discloses an extraction process of dihydromyricetin in vine tea and a preparation process of vine tea functional beverage, wherein the extraction method comprises the steps of pretreatment, countercurrent extraction treatment, pretreatment of filter residue, extraction and combination of the filter residue, reduced pressure concentration of flavonoid extract, crystallization and the like. The leaching method can fully leach the raw materials, can more thoroughly leach residual flavonoid substances in filter residues, ensures high-efficiency extraction of the flavonoid substances, and has high leaching rate and high flavonoid content. Meanwhile, the extraction method adopts a method combining water extraction, ultrasonic extraction and high-pressure extraction, so that potential pollution caused by the use of organic solvents such as ethanol and the like is avoided. The method has high extraction rate and high content of dihydromyricetin. |
