Problems solved by technology

[0003] Nowadays, there are technological methods for processing wolfberry leaves into drinking tea, and these methods all adopt conventional tea processing processes, including sun-drying, withering, rolling, fermentation, drying, etc., especially the drying process, although its purpose is to volatilize Remove the moisture in the tea leaves and fix the shape of the tea leaves. However, during the processing of wolfberry leaves, the drying process will cause a large loss of fermentation liquid and take away the aroma of the tea leaves, and cannot fully retain the active ingredients and nutrients produced by fermentation; In addition, the existing processing of wolfberry leaves is only a single raw material of wolfberry leaves, which makes the tea have defects such as weak taste and single nutritional value, which is not conducive to the development and promotion of wolfberry leaf tea.

Embodiment 1

[0020] A processing method of wolfberry black tea, comprising the steps of:

[0021] (1) Picking and cleaning of fresh leaves: picking fresh leaves of Lycium barbarum from May to September as raw materials, soaking in purified water containing 0.5% to 1% of pesticide degrading enzymes for 10min to 30min, then changing to purified water and washing 3 to 4 times , drain the water;

[0022] (2) sun-drying: spread the fresh leaves on the sun-drying device, and place them outdoors for 4-6 hours, until the water loss rate reaches 8% to 10%, and become sun-dried green leaves;

[0023] (3) Withering: put sun-dried green leaves in an incubator, seal and heat to wither, the thickness of the spread leaves is 1cm to 2cm, the withering temperature is 100°C, and the withering time is 30min, until the leaves become discolored and soft, and become withered leaves;

[0024] (4) Kneading: weigh the withered leaves, add 0.1% cellulase to the withered leaves, stir evenly, put into a kneading mac...

Abstract

The invention belongs to the technical field of tea processing, and relates to a processing method of a wolfberry black tea. The processing method includes the following steps: 1, performing picking:picking fresh leaves of wolfberry trees as raw materials; 2, performing drying in the sun; 3, performing withering; 4, performing twisting; 5, performing fermentation: adding a composite liquid into the twisted leaves, and performing fermentation treatment; 6, performing sterilization; and 7, performing packaging: performing vacuum packaging directly to obtain the wolfberry black tea; or performing centrifugation treatment to obtain leaves and a fermentation liquid, mixing the leaves and fermentation liquid, performing bagging, and performing vacuum packaging to obtain the wolfberry black tea.According to the processing method, the tea leaves after fermentation and sterilization are directly vacuum-packed or mixed and vacuum-packed after centrifugation, so that the nutrients and aroma ofthe wolfberry leaves are fully retained, and the obtained tea has a more intense flavor.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and relates to a processing method of wolfberry black tea. Background technique [0002] Modern research shows that wolfberry leaves are rich in calcium, iron, zinc, selenium and other trace elements necessary for human body, as well as vitamins, carotene and more than ten kinds of amino acids necessary for human body. effect. In daily life, wolfberry leaves can be used in combination with medicines for the treatment of hypertension, diabetes, anemia, vision loss and other diseases; it can also be used to replace tea with single-flavored water for dry throat, thirst, cough, constipation, etc. Relief of symptoms; In addition, wolfberry leaves can also be used for health care, beauty and beauty. [0003] Nowadays, there are technological methods for processing wolfberry leaves into drinking tea, and these methods all adopt conventional tea processing processes, including sun-drying, wither...
