Abstract

The invention mainly relates to process combination for preparing a fresh tea flavor extract, in particular to the process combination for preparing a fresh tea flavor green or black tea extract from fresh tea without fixing at a low temperature by crushing, homogenization, centrifuging, microfiltration and membrane concentration processes.

Description

technical field [0001] The present invention mainly relates to a process combination for the preparation of fresh tea flavor extracts, especially a method for preparing fresh tea flavor extracts under low temperature conditions by using uncooked fresh tea leaves, which consists of crushing, homogenization, centrifugation, microfiltration, and membrane concentration processes. Craft mix of green or black tea extracts. Background technique [0002] Fresh leaf flavored tea beverage is a new type of tea beverage, which has the characteristics of bright color, refreshing taste and pure aroma, and can maintain the unique natural flavor of tea. Fresh leaf tea juice is generally prepared by crushing and pressing green leaves. The prepared product has quality problems such as easy precipitation, unstable color and "cooked soup taste" during storage. [0003] Tea polyphenols in fresh leaves are easily oxidized by oxygen in the air, especially in the presence of aqueous solution and p...
