Embodiment 1

[0021] A raw material of fresh leaves used for the processing of cooked chestnut-flavored green tea is: 50kg of fresh tea leaves whose variety is Longjing 43 and whose tenderness ranges from 1 bud 2 leaves to 1 bud 3 leaves. The fresh leaves are picked on April 20 .

[0022] The specific implementation is as follows:

[0023] (1) The fresh leaves are spread by the greening system of the facility. The ambient temperature of the greening system is controlled at 28° C., and the relative humidity is controlled at 65%. At the same time, it is ventilated for 5 minutes every 1 hour (the greening system of the facility is developed by the Chinese Academy of Agricultural Sciences. Self-developed by the Tea Research Institute, patent number: ZL201420171821.7), reaching input O 2 , to discharge CO 2 The effect is to let the fresh leaves carry out slow and continuous respiration and material conversion.

[0024] (2) When the fresh leaves are spread green to 70% moisture content, use th...

Embodiment 2

[0033] The raw material of fresh leaves used in the processing of a kind of cooked chestnut-flavored green tea is as follows: the picking variety is Zhongcha 108, and the tenderness is 50kg of tea fresh leaves mainly consisting of 1 bud, 2 leaves, and 1 bud and 3 leaves, and the fresh leaves are picked on September 14. day.

[0034] The specific implementation is as follows:

[0035](1) The fresh leaves are spread by the greening system of the facilities. The ambient temperature of the greening system is controlled at 28 ° C, the relative humidity is controlled at 70%, and the ventilation is 5 minutes every 1 hour (the greening system of the facilities is provided by the Chinese Academy of Agricultural Sciences. Self-developed by the Tea Research Institute, patent number: ZL201420171821.7), reaching input O 2 , to discharge CO 2 The effect is to let the fresh leaves carry out slow and continuous respiration and material conversion.

Abstract

The present invention provides a processing method of cooked chestnut flavored green tea. Step-by-step precision controls of facility spreading and water supplementing slow spreading technologies are used to realize a slow orientation transformation of contained components. A three-stage enzyme deactivating technology of an electromagnetic roller is combined to truly realize effects of high temperature enzyme deactivating at high temperature firstly and low temperature secondly, a good aroma is achieved at the same time, and taste, color, luster and quality can also be kept excellent. A maturing and fragrance improving technology is conducted to further enrich aroma components and improves aroma concentration. Rolling and baking are combined with a drying and low temperature baking technology, and characteristics of the cooked chestnut flavor are fixed and highlighted. The method is reasonable in designs and the tea products have purposes of being good in taste and smell, and affordable in prices. By improving and optimizing traditional processing technologies, the special technology is merged into the whole processing processes, and the processing method realizes an upgrading of inner flavor, and thus provides the new green tea products being mellow and refreshing in taste, and having the obvious cooked chestnut flavor in the fragrance.
