FIELD: food industry.SUBSTANCE: invention relates to food industry and may be used at tea factories of primary processing. Freshly plucked, hardened and/or coarse and/or second year tea leaves are washed, air-dried during 3-6 hours, loaded into the reservoir with 12% hydrogen peroxide and maintained in the solution during 3-6 hours. Raw material is cut, twisted and fermented during 2-4 hours at 24-26°C and relative air humidity equal to 96-97% in the process whereof raw material is sprayed with 0.1% potassium hydroxide solution 3-4 times. Then the product is dried and thermally treated in tightly closed boxes at 40-45°C during 4-6 hours, cooled and packed to produce the ready product.EFFECT: invention allows to manufacture a product with high organoleptic and physical-and-chemical indices of low grade raw material, the said indices corresponding, in terms of range, to those of medium and prime grades of tea.1 ex |
