The objective of the invention is a kind of instant green tea and the processing technology thereof developed at above deficiency.The characteristics of instant green tea are because contain anti-cancer and cancer-preventing, the effective ingredient EGCG of anti peroxidation of lipid and hepatoprotective effect in the green tea.EGCG is a kind of polyhydric phenols, it also is the Main Ingredients and Appearance in the so-called Tea Polyphenols, in order to guarantee and outstanding anti-cancer and cancer-preventing, anti peroxidation of lipid and the hepatoprotective effect of bringing into play green tea, will fully extract the effective ingredient EGCG in the green tea, make it to be extracted out fully, will select more efficiently solvent for this reason.The organic solvent that instant green tea is selected is ethanol or acetone, its processing technology is that the warm lixiviate of employing is got, vacuum film concentrates, drying forms, it had both guaranteed the green that green tea is intrinsic, guaranteed that again excited composition caffeine and nutritions extractions such as each seed amino acid, vitamin and trace element wherein are complete, and yield improves more than 1 times than existing technology.The instant green tea that is made by this law can dissolve rapidly in 40 ℃ of-100 ℃ of water, is the yellow green pellucidity, and no residue is worked as with the fresh green tea liquid phase that brews.
The present invention is achieved in that the batching of instant green tea is to divide 10 times of three adding weight of material in the fresh green tea (material) of plucking processing, and the organic solvent of 7 times and 5 times amounts is got through warm lixiviate and to be processed.Organic solvent can be the ethanol of 50-70%, can also be the acetone of 50-70%.
The present invention can be achieved in that also the processing technology of instant green tea is at first to get the fresh green tea (material) of plucking processing then, 10 times of amount 50-70% organic solvents that add weight of material are in water-bath, temperature was soaked 3-5 hour under 30-50 ℃ of temperature conditions, used Xinhua's filter paper (middling speed) to filter time leaching liquor of winning then; Second step was that the 7 times of amount 50-70% organic solvents temperature under 30-50 ℃ of temperature conditions that adds weight of material in the filter residue through once filtering was soaked 2-4 hour, use then Xinhua's filter paper (middling speed) filter leaching liquor for the second time; The 3rd step was to soak 1-3 hour adding 5 times of weight of material amount 50-70% organic solvents temperature under 30-50 ℃ of temperature conditions again in the filter residue of twice filtration, use then Xinhua's filter paper (middling speed) filter leaching liquor for the third time; The 4th step was the 5 times of amounts water commonly used that adds weight of material in the filter residue that filters through three times, and temperature was soaked 0.5-1 hour under 50-70 ℃ of temperature conditions, with Xinhua's filter paper (middling speed) filter the 4th leaching liquor; The 5th step was to merge first, second and third time leaching liquor, carries out vacuum film and concentrate under 40-50 ℃ of temperature conditions, reclaimed the organic solvent that steams simultaneously, in concentrate, add the 4th leaching liquor, continue vacuum film and concentrate,, make the loose drying thing until draining solvent; The 6th step was that the loose drying thing that the 5th step made is pulverized, and filtered with 100 mesh sieves then, can make instant green tea.
Good effect of the present invention is:
