However, the current consumption of Chinese toon is mostly young buds, which have a strong harvest season and a short harvest period. If they are placed at room temperature for 1-2 days, they are prone to withering, rot and other quality deterioration, and their nutrition and flavor are greatly reduced. At present, most of the processing of Chinese toon still stays in the traditional processing technology, such as pickled products, Chinese toon pickles, canned Chinese toon, etc. During the

Embodiment 1
[0017] Embodiment one: a kind of Chinese toon fermented black tea preparation method of the present invention comprises the following steps:
[0018] (1) Withering: Pick fresh young leaves of Toona sinensis in summer and autumn, spread them evenly, place them outdoors with a thickness of 8cm, and wither for 24 hours in the sun, so that the leaves are soft, the stems are not easy to break, the leaves are dark green and dull, and the grass gas is reduced , the water content is 55-65%.
[0019] (2) Kneading: Knead under air pressure for 10 minutes → add light pressure and knead for 8 minutes → air pressure for 3 minutes → increase pressure and knead for 10 minutes → air pressure for 5 minutes → increase pressure and knead for 8 minutes → apply air pressure for 3 minutes → add light pressure and knead for 3 minutes. Knead for 20 minutes, and the kneading time is about 70 minutes in total, so that the destruction rate of leaf cell tissue reaches more than 80%, so as to fully fermen...

[0025] Embodiment two: a kind of Chinese toon fermented black tea preparation method of the present invention comprises the following steps:
[0026] (1) Withering: Pick fresh young leaves of Chinese toon in summer and autumn, spread them evenly, place them outdoors, with a thickness of 8cm, and wither for 1.5 days in the sun, so that the leaves are soft, the stems are not easy to break, the leaves are dark green and dull, and the grass smells Reduced, the water content is 55-65%.
[0027] (2) Kneading: Knead under air pressure for 5 minutes → add light pressure for 10 minutes → air pressure for 3 minutes → increase pressure for 5 minutes → air pressure for 5 minutes → increase pressure for 10 minutes → apply light pressure for 10 minutes, air pressure for 10 minutes, knead The total time is about 58 minutes, so that the destruction rate of leaf cell tissue reaches more than 80%, so as to fully ferment.
[0028] (3) Fermentation: adopt natural fermentation, spread the rolled ...

Abstract
The invention discloses a preparation method of toona sinensis fermented black tea. The preparation method comprises the following steps: (1) withering; (2) rolling; (3) fermenting; (4) primarily drying through gross fire; (5) drying by final fire; (6) spreading for airing; and (7) packaging. According to the preparation method, toona sinensis leaves are adopted to be fermented to prepare tea for the first time, and are properly withered and fermented, so that the enzyme activity of the fresh leaves is activated, macromolecule nutrient substances in the fresh leaves are degraded into absorbable micromolecule substances, the content of aqueous extracts is increased, and nutrients in tea water are rich; furthermore, through sufficient fermentation, the bitter taste of the finished tea is improved, so that the tea is mellow to be easily accepted by people. Meanwhile, a conventional process of drying by final fire can be changed, and a two-time drying method is adopted, so that the toona sinensis fermented black tea has special quality. The content of functional ingredients such as total flavonoids and soluble sugar can be increased, so that the toona sinensis fermented black tea is endowed with a certain health care function.
Description
technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for preparing Chinese toon fermented black tea. Background technique [0002] Toona sinensis belongs to the deciduous tree of the family Meliaceae and has a cultivation history of more than 2,300 years. It is an important specialty resource integrating nutrition, health care and medicinal functions in my country. The young shoots and leaves of Toona sinensis are rich in aroma and unique in taste, rich in protein, amino acid, vitamins and various trace elements, and have high nutritional value. In addition, Chinese toon is also rich in polyphenols, flavonoids, saponins, alkaloids and other biologically active substances, which have the effects of lowering blood pressure, lowering blood lipids, anti-inflammatory, anti-virus, anti-aging, and weight loss. "Compendium of Materia Medica" pointed out that the leaves, buds, roots, bark and fruits of Toona si...
