Embodiment 1

[0024] The processing method of Longjing Chinese toon tea, described processing method comprises the steps:

[0025] (1) Picking and rinsing of Chinese toon buds and Longjing: pick fresh and complete Chinese toon buds and Longjing without old stems, and gently shake and rinse in clean water to remove floating dust;

[0026] (2) Pretreatment of Chinese toon buds and Longjing: Step (1) Soak the rinsed Chinese toon buds in pretreatment agent A for 30 minutes. The pretreatment agent A is water-soluble dextran with a mass fraction of 1% and 0.5% reduced glutathione mixed aqueous solution, pretreatment temperature 5°C, pretreatment agent pH 5.0, the volume ratio of the wet weight of Chinese toon buds to the pretreatment agent is 1:3; step (1) Rinse and soak Longjing Pretreat in pretreatment agent B for 10 minutes, said pretreatment agent B is a reduced glutathione aqueous solution with a mass fraction of 0.3%, pretreatment temperature is 25°C, pretreatment agent pH is 6.8, Longjing ...

Abstract

The invention relates to a processing method of Longjing and Chinese toon tea. The processing method comprises the following steps: (1) picking Chinese toon buds and Longjing tea leaves and rinsing; (2) pre-treating the Chinese toon buds and the Longjing tea leaves; (2) cooking the Chinese toon buds; (4) carrying out fixation on the Longjing tea leaves; (5) rolling; (6) frying. The inventor takes Chinese toon as a raw material, and a certain amount of the Longjing tea leaves are added; then the Longjing and Chinese toon tea is processed through a process provided by the invention; the taste of the Longjing and Chinese toon tea is suitable for interests of people drinking traditional tea, and a health-care effect of the Chinese toon can be exerted, so that the range of beneficiaries of the Chinese toon is wider, and the effect is more obvious; the cost is more reasonable and the quality guarantee period is long, and is not restricted by seasons and storage and transportation manners.

Description

technical field [0001] The invention relates to a processing method of Longjing Chinese toon tea, which belongs to the technical field of tea processing. Background technique [0002] Chinese toon is Chinese toon bud, which is a perennial deciduous tree. It is eaten with its fresh stems and leaves, such as Chinese toon scrambled eggs and Chinese toon dumplings. It is delicious and has high nutritional value. In addition, Chinese toon is also a medicine, which has the effect of expelling wind and dampness, can prevent and treat rheumatism, and can also regulate diabetes. Chinese toon buds mainly grow in early spring. At present, the picking period of Chinese toon is short, fresh and perishable. If it is placed at room temperature for 2-3 days, its freshness, flavor or texture will be greatly reduced, and its unique edible value will almost be lost in less than a week. Toona sinensis has a strong respiration intensity after harvest, is easy to fade, and is very easy to lignif...
