METHOD FOR PRODUCING TEA IN PARTICULATE OR LEAF FORM WITH REDUCED LABOR AND PLANT COSTS

摘要

A method for the production of tea in particulate or leaf form, comprising a step of harvesting the parts of the tea plant to be treated, characterized in that it comprises a step of freezing the parts of the tea plant at a temperature which is substantially between -40 °C and -150 °C to cause the rupture of their cell walls and of the sub-cell organelles due to the freezing of the protoplasm, and thawing step of causing a mixing of the oxidases and substrates which escape from the sub-cell organelles which are ruptured by the freezing step; after the freezing step and before the thawing step the parts of the plant are subjected to a mechanical action to detach the leaves from the remaining parts of the plant that are subjected to treatment. Said parts of the plant are then subjected to separation into the various elements that compose them.
