Embodiment 1

[0016] A kind of preparation method of mulberry leaf instant tea:

[0017] (1) Drying process: remove impurities from the fresh mulberry leaf raw materials, and dry them by blowing air at 80°C to 20-28% of the original weight;

[0018] (2) Pulverization process: the dried mulberry leaves are pulverized and sieved to 20-40 meshes;

[0019] (3) The first extraction process: Put the mulberry leaves into an extraction tank with microwave and temperature control, heat the purified water 12 times the weight of the human mulberry leaves while stirring, and heat at 95°C for 2 hours;

[0020] (4) Filtration for the first time: After the extraction is completed, cool the tea slurry after stirring and leaching to room temperature in a sealed leaching tank, first filter it with an 80-mesh stainless steel filter, and then use a filter with a filter aperture of 0.5 μm The ceramic membrane is used for fine filtration, and the operating conditions are that the temperature is lower than 65°C,...

[0028] A kind of preparation method of mulberry leaf instant tea:

[0029] (1) Drying process: remove impurities from the fresh mulberry leaf raw materials, and dry them by blowing air at 80°C to 20-28% of the original weight;

[0030] (2) Pulverization process: the dried mulberry leaves are pulverized and sieved to 20-40 meshes;

[0031] (3) The first extraction process: Put the mulberry leaves into an extraction tank with microwave and temperature control, heat the purified water 10 times the weight of the human mulberry leaves while stirring, and heat at 95°C for 2 hours;

[0032] (4) Filtration for the first time: After the extraction is completed, cool the tea slurry after stirring and leaching to room temperature in a sealed leaching tank, first filter it with a 60-mesh stainless steel filter, and then use a filter with a filter aperture of 0.5 μm The ceramic membrane is used for fine filtration, and the operating conditions are that the temperature is lower than 65°C, ...

Embodiment 3

[0040] A kind of preparation method of mulberry leaf instant tea:

[0041] (1) Drying process: remove impurities from the fresh mulberry leaf raw materials, and dry them by blowing air at 80°C to 20-28% of the original weight;

[0042] (2) Pulverization process: the dried mulberry leaves are pulverized and sieved to 20-40 meshes;

[0043] (3) The first extraction process: Put the mulberry leaves into an extraction tank with microwave and temperature control, heat the purified water 10 times the weight of the human mulberry leaves while stirring, and heat at 95°C for 2 hours;

[0044] (4) Filtration for the first time: After the extraction is completed, cool the tea slurry after stirring and leaching to room temperature in a sealed leaching tank, first filter it with a 120-mesh stainless steel filter, and then use a filter with a filter aperture of 0.5 μm The ceramic membrane is used for fine filtration, and the operating conditions are that the temperature is lower than 65°C,...

Abstract

The invention discloses a preparation method and application of mulberry leaf instant tea. The preparation method comprises the following steps of: adopting fresh mulberry leaves as preparation raw materials; and adopting a drying process, a crushing process, a primary extracting process, a primary filter process, a microwave-assisted compound enzyme treatment process, a secondary extracting process, a secondary filter process, a process of combining and extracting extract liquor obtained twice, a drying process and a pelletizing process; an microwave-assisted compound enzyme extracting technology is used for sufficiently breaking and dehydrating cellulose and pectin substances, so that release and dissolution of functional ingredients in mulberry leaves are increased, and therefore, the yield of gamma-aminobutyric acid with a health value and content of functional components such as 1-deoxynojirimycin are improved. The prepared mulberry leaf instant tea is strong in instant solubility, has remarkable healthcare effect of reducing blood sugar, reducing fat and reducing pressure for three-high crowd; the processing method is strong in maneuverability and is beneficial to industrial development of national mulberry leaf instant tea.

Description

technical field [0001] The invention relates to the processing field of health-care tea, in particular to a preparation method and application of mulberry leaf instant tea. Background technique [0002] At present, a large number of people at home and abroad have physiological phenomena of high blood lipids, blood sugar, and blood pressure, and they are in great need of health care drinks that use natural plants as raw materials. Mulberry leaf is a "medicine and food homologous" plant confirmed by the Ministry of Health, and is listed by the International Food Hygiene Organization as "one of the top ten health foods for human beings in the 21st century. In recent years, mulberry leaf tea has developed rapidly and become popular in many countries and regions. The processing technology of mulberry leaf tea in foreign countries has become mature, but our country is in the development period, which makes the mulberry leaf tea produced in our country lack of competitiveness in th...
