Abstract

The invention discloses a production method of Vitex japonica leaf tea extract. The Vitex jasmine leaf tea extract is made from Vitex vitae leaf tea extract through the steps of raw material preparation, color protection treatment, thermal extraction, ultrasonic extraction, crushing, mixing, sublimation drying, finishing and packaging, etc. made. The Vitex Vitex leaf tea essence produced by the method uses the Vitex Vitex Vitex leaf widely existing as raw material, which reduces the production cost, and can fully retain the active substances of the raw material through thermal extraction and ultrasonic extraction treatment, and adopts the method of sublimation drying, which reduces the loss of nutrients and improves the production efficiency. The utilization rate of raw materials is improved, and the finished tea essence has health effects such as relieving exterior heat and clearing away heat, promoting dampness and detoxification.
