Embodiment Construction

[0031] The present invention as Figure 1-6 As shown, the following procedures are included in sequence, pretreatment of fresh leaves (picking fresh leaves, grading, cooling, preservation), withering, greening, greening, kneading (kneading forming), drying and aromatherapy and packaging (finished product packaging)

[0032] The fresh leaves are the fresh leaves of tea in summer and autumn; in the prior art, the fresh leaves of tea in summer and autumn are generally discarded, such as Yangzhou Lvyangchun green tea, but the present invention effectively utilizes the fresh leaves similar to tea leaves in summer and autumn, avoiding the waste of resources waste;

[0033] The withering process is light-matched withering. The pre-treated fresh leaves are placed in the light-matched withering machine for withering. The light-matched withering machine includes red-orange light and blue-violet light. The source power is 50~150W, the UV lamp power is adjusted to 200~800W, and the withe...

Abstract

A processing method of high tea polysaccharide oolong tea. It involves processing oolong tea with green tea leaves discarded in summer and autumn. Improve the retention rate of tea polysaccharides in discarded tea in summer and autumn, with strong aroma and unique characteristics, which is beneficial to industrial mass production. It includes the following steps in sequence: pretreatment, withering, greening, killing, kneading, drying, and encapsulation of fresh leaves. For withering operation, the light distribution withering machine includes red-orange light and blue-violet light. The use of compound light makes the pigment and other material components in the fresh tea leaves absorb light energy, thereby increasing the activity of related enzymes and causing a series of biochemical reactions. Different photoreceptors in leaf cells that are selective for the absorption of the solar spectrum. Synergistic withering of artificial light-ultraviolet light is based on colored light, adding ultraviolet light irradiation, shortening working hours, improving withering efficiency, promoting protein degradation and emitting green grass gas, while minimizing polysaccharide degradation.

Description

technical field [0001] The invention relates to the field of tea processing; in particular, it relates to a processing technology for processing commercial oolong tea by using fresh leaves of green tea discarded in summer and autumn as raw materials. Background technique [0002] The production of tea has obvious seasonality, and the picking season determines the type of product. After the fresh leaves are picked, they must be processed within a relatively short period of time, otherwise they are easily affected by external conditions and the quality of the finished product will deteriorate, resulting in a sharp drop in commodity value. Pretreatment and preservation are key steps in the tea making process. And existing various pretreatment fresh-keeping technologies more or less exist certain deficiency. The withering process of oolong tea is mainly to make the leaves lose a small amount of water, promote the slow enzymatic reaction of the contained substances, and lay the...
