White tea low temperature counterflow extraction technique

Abstract

The invention provides a process of low-temperature multi-stage countercurrent extraction of white tea. The process comprises: extracting tea leaves in three extraction stages in multi-stage countercurrent extraction equipment to obtain high-quality tea liquid. The three extraction stages include: primary extraction stage, secondary extraction stage and leaching stage. Compared with the prior art, the extraction efficiency is remarkably increased, the utilization rate of tea leaf during the process is increased, and the production cost is minimized to gain higher profit for enterprise. Additionally, the process has the advantages of no strict requirement for equipment, high controllability and operability and low energy consumption, and is suitable for large-scale production of tea beverages.

Description

Low-temperature multi-stage countercurrent extraction technology of white tea technical field The invention belongs to the field of beverage processing, and more specifically relates to a low-temperature multi-stage countercurrent extraction technology of white tea. Background technique White tea is a slightly fermented tea and is one of the six major teas in my country. It has the effects of "three drops" (lowering blood pressure, lowering blood fat, and lowering blood sugar) and "three antis" (anti-tumor, anti-radiation, and anti-oxidation), and the anti-cancer effect is more significant than any tea; Generally, water extraction is used, which consumes a lot of energy, has low extraction efficiency, low concentration of extracted tea juice, and poor tea juice quality (color, aroma, and taste). Contents of the invention The purpose of the present invention is to provide a low-temperature multi-stage countercurrent extraction technology for white tea. This technology n...
