[0034] Preparation of Example 1 of Organic Green Tea Raw Material of the Invention

[0035] A. Take 20 parts of green tea and divide them into two groups, 10 parts of green tea in each group. One group of green tea is ground to obtain powder, and then distilled water of 2 times the mass of the green tea is added and placed in a microwave extractor. 70r·min -1 Stir at 80°C for 50 minutes at a stirring speed of 80°C to obtain a crude green tea liquid, which is filtered through a 1mm microporous filter to obtain a green tea filtrate. The obtained green tea filtrate is concentrated under reduced pressure to remove the contained water. Obtain the dry paste, after pulverizing the dry paste, sieving into a 100 mesh powder, the powder is green tea powder;

[0036] B. Another group of green tea is steamed, the steam temperature is 90℃, and the steaming time is 70 minutes; the flow of fresh leaves is calculated as 6.5kg, and the control steam flow is 120kg / h;

[0037] C. Carry out the first r...

[0041] Preparation of embodiment 2 of organic green tea raw material of the present invention

[0042] A. Take 40 parts of green tea and divide equally into two groups, each group of 20 parts of green tea, among which, one group of green tea is ground to obtain powder, and then 2.5 times the mass of the first group of green tea is added with distilled water, which is extracted by microwave 75r·min in the machine -1 Stir at a temperature of 83°C for 60 minutes at a stirring speed of, to obtain a crude green tea, which is filtered through a 3mm microporous filter to obtain a green tea filtrate. The obtained green tea filtrate is concentrated under reduced pressure to remove the contained water. Obtain a dry paste, after pulverizing the dry paste, sieving into a 150 mesh powder, the powder is green tea powder;

[0043] B. Take 10 parts of Zheng'an white tea through double withering and then heating withering, the water content of Zheng'an white tea is reduced by 75%, and then the Zhen...

[0050] Preparation of Example 3 of Organic Green Tea Raw Material of the Invention

[0051] A. Take 80 parts of green tea and divide them into two groups, 40 parts of green tea in each group. One group of green tea is ground to obtain powder, and then distilled water 3 times the mass of the first group of green tea is added, and it is extracted by microwave In the machine at 80r·min -1 Stir at 85°C for 80 minutes at a stirring speed of 85°C to obtain a crude green tea solution, which is filtered through a 5mm microporous filter to obtain a green tea filtrate. The obtained green tea filtrate is concentrated under reduced pressure to remove the contained water. Obtain a dry paste, after pulverizing the dry paste, sieving into a powder of 200 mesh, the powder is green tea powder;

[0052] B. Take 20 parts of Zheng'an white tea through double withering and then heating withering, the moisture content of Zheng'an white tea is reduced by 80%, and then the Zheng'an white tea is put into t...

Abstract

The invention discloses an organic green tea leaf processing technology which includes the steps: first, equally dividing green tea into two groups including a first group and a second group, and grinding, stirring, compressing and crushing the first group of green tea to obtain a first group of green tea powder; second, withering, primarily drying, cooling, re-baking and frying 5-10 parts of Zhengan white tea; third, grinding and stirring the Zhengan white tea fried in the second step to obtain Zhengan white tea extracting solution; fourth, steaming and primarily rolling the second group of green tea in the first step to obtain organic green tea. Amino acid and chlorophyll contents of the prepared green tea are higher than those of traditional steamed, pan-fired and baked green tea, and the caffeine content of the green tea is lower than that of the traditional steamed, pan-fired and baked green tea.

Description

Technical field [0001] The invention belongs to the technical field of tea processing technology, and particularly relates to a processing technology of organic green tea leaves. Background technique [0002] Green tea refers to a product made from the new leaves or buds of the tea tree, without fermenting, after finishing, or shaping and drying. The color of the finished products is mostly green. Drinking green tea regularly can prevent cancer, lower blood fat and lose weight. [0003] The existing green tea processing is simply divided into three steps: curing, rolling and drying. Among them, the key is curing. The methods of curing include stir-frying, steaming, soaking, and radiation curing. The fresh leaves are killed and the enzyme activity is inactivated. The various chemical components contained therein are basically subjected to physical and chemical changes under the condition of no enzyme influence by the action of heat, thus forming the quality characteristics of gree...
