Abstract

The invention provides a processing method of sweet-scented osmanthus black tea. The method comprises the following steps: rolling: mixing withered fresh tea leaves and spread sweet-scented osmanthus,and performing joint rolling to obtain rolled leaves; fermentation: fermenting the rolled leaves to obtain fermented leaves; stir-frying: stir-frying the fermented leaves to obtain stir-fried crude tea; and drying: drying the stir-fried crude tea, and removing the sweet-scented osmanthus to obtain the sweet-scented osmanthus black tea. The withered fresh tea leaves and the spread sweet-scented osmanthus are rolled and fermented together, so that inclusions of the fresh tea leaves and the sweet-scented osmanthus permeate each other, the fresh tea leaves fully absorb the aroma of the sweet-scented osmanthus, aroma components in the fermented sweet-scented osmanthus and tea polyphenol in the tea leaves form a complexing state, and the sweet-scented osmanthus aroma is more durable; and finally, the stir-frying and the drying are carried out to terminate fermentation to obtain the sweet-scented osmanthus black tea. By adopting the method provided by the invention, the sweet aroma of the sweet-scented osmanthus black tea is finally embodied, the sweet aroma is rich, the green smell completely disappears, the aroma is balanced, flavor change does not occur in the storage process, and thearoma is stable and lasting.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a processing method of sweet-scented osmanthus black tea. Background technique [0002] Osmanthus tea is one of the characteristic teas in China. It belongs to scented tea. It is scented from osmanthus and tea leaves. It has a strong and lasting fragrance. The soup of osmanthus black tea is red and bright. Osmanthus tea has the effects of warming and nourishing yang, whitening the skin, detoxifying the body, relieving cough and reducing phlegm, and nourishing the lungs. Traditional sweet-scented osmanthus tea is made through the processes of tea embryo preparation, fresh osmanthus harvesting, tea embryo scenting, cooling through flowers, continued scenting, blooming, and drying. The sweet-scented osmanthus tea made in this way does not have a long-lasting aroma and has an obvious astringent taste. For solving this problem, Chinese patent literature (CN109953154A) provides a kind o...
