Processing method of guava leaf tea powder

Abstract

The invention discloses a processing method of guava leaf tea powder. The processing method includes the steps of preparing guava leaf, and performing color protecting, thermal extraction, ultrasonic extraction, crushing, mixing, sublimation drying, finishing packaging and the like. The guava leaf tea powder is made with widely resourceful guava leaf, and production cost is lowered; double steam fixations enable elimination of inherent bitter of the guava leaf and improvement of the taste of finished tea powder; thermal extraction and ultrasonic extraction help retain active substances of the raw material fully; sublimation drying helps reduce loss of nutrients and increase utilization of the raw material; the finished tea powder has the health effects of clearing heat and toxin, astringing to arrest diarrhea, lowering blood sugar and the like.

Description

technical field

[0001] The invention relates to a processing method of tea powder, in particular to a processing method of guava leaf tea powder. Background technique

[0002] Guava leaves, also known as fantao leaves, mari gan, etc., are bitter in taste; astringent; flat in nature, "Nanning City Drug Chronicle" records: "convergence and antidiarrheal. Treat diarrhea, chronic dysentery, eczema, and traumatic bleeding." The leaves contain β -Sitosterol, triterpenoids. It also contains quercetin, guava ellagitan, leucocyanidin, guava ellagitan, and guava acid. And contains volatile oils, such as eugenol, cis-3-hexen-1-ol, hexenol, hexanal, and methyl benzene physate, β-phenylhexyl hexanoate, methyl cinnamate, apple Acids, resins, waxes and tannins, etc. At present, the processing and utilization of guava leaves is still in the stage of harvesting as mature medicine. For example, the patent application number 201410770330.9 discloses a kind of herbal tea containing guava lea...
