Method for processing lonicera japonica tea by reducing loss of chlorogenic acid

Abstract

The invention discloses a method for processing lonicera japonica tea by reducing loss of chlorogenic acid. The concrete scheme comprises: directly processing or storing in a controlled atmosphere cold storage at the temperature range of 0 DEG C - 5 DEG C after plucking, then directly and quickly removing green with a high temperature steam, wherein the steam temperature range is 90 DEG C - 100 DEG C, the green removing time range is 88 - 92 seconds; then quickly cooling with cold air, wherein the cold air temperature is 3 DEG C - 7 DEG C, and the time for cooling is for 88 - 92 seconds; rapidly drying with high temperature and hot air, wherein the hot air temperature is 90 DEG C - 110 DEG C, and the time for drying is for 40 - 45 minutes; finally cooling and sealing. Therefore, before polyphenoloxidase is failed to decompose chlorogenic acid, the activity is destroyed due to high temperature and dehydration, then a rapid cryogenic cooling and drying with a high temperature are performed, so that a temperature range of effective activity can be avoided to converge the activity of polyphenoloxidase, thereby the effect of reducing loss of chlorogenic acid can be achieved as well as the product quality can be substantially improved.

Description

technical field [0001] The invention relates to a processing method of camellia japonica tea, in particular to a processing method of jasmine jasmine tea which reduces the loss of chlorogenic acid. Background technique [0002] Mountain silver flower is one of the traditional Chinese medicinal materials, and it is also a raw material for both medicine and food. It has the effect of clearing away heat and detoxification, and cooling wind heat. In the field of traditional Chinese medicine, it has been used for the treatment of carbuncle, swollen furuncle, sore throat, erysipelas, toxic heat and blood dysentery, wind-heat cold, and warm-heat disease; now it is more used for health care tea; therefore, it is in great demand. Mountain Yinhua produces flowers in June every year. During the flowering period, there are many cloudy and rainy days. The flowers have a high water content and are prone to mold and deterioration. Therefore, the picked flowers need to be dehydrated and dri...
