Problems solved by technology

Although it provides a new method of killing mulberry leaf tea, it still has the problem that the mulberry leaves will change color if the mulberry leaves are kept in boiling water for too long, and the nutrients and health-care functional substances contained in the mulberry leaves will change with the treatment. The longer the time, the more the problem is dissolved in water or destroyed

Abstract

The invention discloses a quality-guaranteeing refining processing method for spring mulberry leaf tea. The method is characterized by being conducted through the following steps: (a), raw material collection: mulberry buds between early March and the Tomb-sweeping Day and first two tender leaves close to each mulberry bud are selected; (b) fixation with boiling water: the mulberry buds and the tender mulberry leaves are placed into the boiling water, dirt on the mulberry leaves and grass flavor of the mulberry leaves are removed during boiling and stirring, and primary fixation is performed for 30-80 s; (c) color fixation with cold water: the mulberry buds and the tender mulberry leaves after primary fixation are placed into the cold water for cooling and color fixation; (d) draining: the materials fished out of the cold water are spread on a mesh belt of a mesh belt conveyor to drain water drops, and a uniform water film is attached to the surfaces of the materials; (e) secondary fixation: the materials are fed into a roller type hot air dryer for ultra-high-temperature rapid fixation; (f) rapid cooling with cold air: the materials are cooled rapidly with a cooler; (g) product obtaining after rolling, shape forming, aroma enhancement and drying.

Description

technical field [0001] The invention relates to a processing method and product of tea, in particular to a processing method and product of quality-preserving and refined spring mulberry tea. Background technique [0002] As we all know, modern medicine has proved that mulberry leaves contain a variety of vitamins and minerals, amino acids, carbohydrates and plant fibers. The crude protein content of mulberry leaves accounts for 23% of the total dry matter. Mulberry leaves contain 17 kinds of amino acids, 6% of crude fat, 25% of soluble carbohydrates, 10% of crude fiber, and a large amount of vitamin C and B1 , B2 and folic acid, carotene, calcium, phosphorus, iron, manganese, sodium, etc., also contains a lot of flavonoids. Its amino acid composition and content are very similar to those of rapeseed pollen, among which the 8 kinds of amino acids necessary for the human body account for 44.9% of the total amino acids. In 1993, the Ministry of Health of the People's Republi...
