Preparation method of seven-leaf tea

Abstract

The invention relates to a preparation method of seven-leaf tea, and belongs to the field of health care products. The preparation method of the seven-leaf tea comprises the steps that tea harvestingis carried out, specifically, healthy and fresh panax notoginseng leaf pieces with good growth conditions and without worm bites are picked; withering is carried out, specifically, the picked fresh panax notoginseng leaf pieces are exposed to the air to lose a part of moisture; tossing is carried out, specifically, firstly the moisture is disappeared averagely, then oxidation is promoted with mutual friction of leaves; fermentation is carried out, specifically, the panax notoginseng leaf pieces after withering are placed in an enamel tank for fermentation for 24-28h; fixation is carried out, specifically, the fermented panax notoginseng leaf pieces are placed in an oven with the temperature of 105-110 DEG C for fixation for 5-10 minutes; rolling is carried out, specifically, the tea leavesare rolled for 20-30 minutes like kneading dough after fixation; and drying is carried out, specifically, drying is carried out after tea rolling, the moisture is evaporated, and the seven-leaf tea is obtained. According to the preparation method of the seven-leaf tea, through the steps of tea harvesting, withering, tossing, fermentation, fixation, rolling, drying and the like, the panax notoginseng leaf pieces are made into the seven-leaf tea for brewing drinking, effective components of the leaf pieces in the preparation process are not damaged, and a great curative effect is achieved for activating blood, removing swelling and silting and reducing blood sugar and blood fat after long-term drinking. The preparation method of the seven-leaf tea is simple and convenient to operate, reduces the production costs of the seven-leaf tea, and can better serve the fields of health care product processing.

Description

technical field [0001] The invention relates to a preparation method of seven-leaf tea, which belongs to the field of health care product processing. Background technique [0002] Panax notoginseng (Burk.) F.H.Chen is a perennial herb. It is the main raw material of large varieties of Chinese patent medicines such as Yunnan Baiyao, Compound Danshen Dripping Pills, Pien Tze Huang, and Xuesai Tong. Pillar industries play an important role in promoting the economic and social development of the region. [0003] Notoginseng leaves are palmate compound leaf whorls and are born on the stem end. The number of leaves is related to the growth period. Most of them have two leaves of Notoginseng in 1a, 2-3 leaves of Notoginseng in 2a, and 3-4 leaves of Notoginseng in 3a The leaves are mostly, and each compound leaf has 5-7 leaflets, the leaflet in the middle is larger, and the edge of the leaflet is mostly serrated, and there are also smooth and double serrated. The content of saponi...
