Abstract

The invention relates to a preparation method for fructus forsythiae leaf tea and belongs to the technical field of using fructus forsythiae leaves to prepare green tea. The technical problem of providing a processing method using fructus forsythiae leaves to prepare green tea is solved. The technical scheme is that picked fresh fructus forsythiae leaves are evenly and flatly spread to be aired for 1 to 2.5 hours at the temperature of 14 DEG C to 18 DEG C, the spread and aired fructus forsythiae leaves are arranged in a green tea rocking machine, temperature is controlled between 23 DEG C to 28 DEG C, relative humidity is 60% to 75 %, green tea rocking is carried out every one hour for 6 to 9 hours, rocked fructus forsythiae leaves can be killed out for 8 to 14 minutes at the temperature of 105 DEG C to 130 DEG C, the killed out fructus forsythiae leaves are cooled to 38 DEG C to 44 DEG C to be packed and rolled in a packing and rolling machine for 4 to 7 times, and finally end product fructus forsythiae leaf green tea can be achieved by drying in a gradient heating mode. The preparation method is widely applied to the technical field of manufacturing fructus forsythiae leaf green tea.

Description

technical field [0001] The invention discloses a method for preparing green tea with forsythia leaves, which belongs to the technical field of green tea prepared from forsythia leaves. Background technique [0002] Forsythia suspensa (Thunb.) Vahl, also known as: Lian, Yiqiao ("Er Ya"), Lanhua, Zhe, Zhegen, Sanlian ("The Classic"), Liancao ("Er Ya" Guo Pu Note), Daqiao ("Tang Materia Medica"), belongs to Oleaceae Oleaceae Forsythia. Forsythia leaves contain 18 essential amino acids, glycosides such as forsythin and forsythiaside, flavonoids such as rutin, and are rich in trace elements such as fluorine, selenium, calcium, potassium, zinc, iron, etc., not only It has good health care effect and certain medicinal value, so it has high development and utilization value. Folk drinking forsythia leaf tea has a long history, and in recent years, many scholars have studied the pharmacological effects of forsythia leaf extract. Hou Gaixia et al.
