Description
Technical Field
The invention relates to the technical field of jasmine tea preparation, and particularly relates to a process for scenting jasmine tea by using clean jasmine oil.
Background
The jasmine tea is prepared by mixing jasmine and tea leaves, and finally the tea with flowers but not flowers is formed.
The traditional manufacturing process is five scenting and one time of smoking, wherein the first scenting is to select the following scents in the sunny night 9: 00-10: 00 the dried tea leaves and the fresh jasmine tea are mixed and stirred in a ratio of 2:1, so that the tea leaves and the jasmine flowers are fully contacted to absorb the fragrance of the jasmine flowers, and the fragrance in the flower fragrance of the jasmine flowers is the best in the period of time. After mixing, the height of the tea pile formed by the tea leaves and the jasmine is controlled to be 45-50 cm, so that excessive temperature rise is avoided, and the tea leaves are fermented. In the early morning, flower ventilation treatment is carried out, namely, the reactor is spread out and spread for cooling, so that the temperature in the reactor is dispersed to avoid fermentation. Mixing after radiating for half an hour, scenting again, stacking at a new position, separating tea and jasmine by a flower screening machine at 8: 00-9: 00 in the next morning, drying the tea, and drying by a drying machine for 7 minutes at 90-130 ℃; the second scenting process is the same as the first scenting process, and the ratio of tea to flower is controlled to be 1: 0.45; the ratio of tea to flower is controlled to be 1:0.4 as before the third scenting; the ratio of the four scents to the tea flower is controlled to be 1: 0.35; the ratio of tea to flower of the five scents is controlled to be 1:0.3, and finally, a jacquard process is carried out, and the tea dried by the five scents is mixed for 4-5 hours according to the ratio of 1:0.08, so that the flower delicate flavor of the tea is improved.
The current end plates of this technique are: the concentration and the persistence of the aroma in the tea are poor, the processing technology has the defects of large flower mixing amount, high cost, low utilization rate of jasmine flower aromatic components, high pile of flowers and tea, easy heating and fermentation of the tea to influence the brightness of the scented tea, increased brittleness of the tea and difficult storage.
