Abstract

The present invention discloses a preparation method of compound instant Zijuan (camellia sinensis var. asssamica) tea powder with high anthocyanin content, mainly relates to the technical field of agricultural and sideline product deep processing, and particularly relates to a method of extracting anthocyanin from black Chinese wolfberry fruits and compounding the anthocyanin with the tea powder extracted from the Zijuan tea and containing nutrients of anthocyanin, tea polyphenols, caffeine, zinc, etc. Firstly, vitamin C is added into the fresh black Chinese wolfberry fruits, the black Chinese wolfberry fruits are broken to prepare black Chinese wolfberry fruit slurry, an ultrasonic treatment is conducted to obtain a crude extract, the crude extract is subjected to a vacuum and low temperature concentration to obtain concentrated liquid, the black Chinese wolfberry concentrated extract liquid is mixed evenly with Zijuan tea juice, and the mixture is spray-dried to obtain the compound instant Zijuan tea powder. The prepared product is green and environmentally friendly, less in vitamin C and anthocyanin loss, stable in anthocyanin storage, high in tea polyphenol content, and good in anti-aging health-care effects, and can effectively maintain soup color and aroma of original tea leaves after brewing.
