Description
Technical Field
The invention belongs to the technical field of preparation of composite functional black tea, and particularly relates to a preparation method of eucommia ulmoides composite functional black tea.
Background
Eucommia ulmoides leaves are medicinal and edible homologous materials approved by the state (national food product letter (2019) 311), and cyclocarya paliurus leaves are new resource food raw materials recognized by the state (state Wei Jianwei 2013, no. 10). The raw materials are recognized by countries, and the safety is high.
At present, most of the existing eucommia ulmoides tea is processed by adopting a green tea process, and the eucommia ulmoides tea is heavy in grass green taste and bitter and astringent in mouthfeel, so that the appetite and the palatability are influenced; the loss of effective components is serious, and the health-care function of the product is influenced; turbid soup color affects visual impression. Meanwhile, the existing eucommia ulmoides tea is relatively single in function, and lacks the support of the traditional Chinese medicine theory of 'compound compatibility and function superposition'. Therefore, a new eucommia ulmoides composite functional black tea and a preparation method thereof are needed to be designed.
Through the above analysis, the problems and defects of the prior art are as follows:
(1) Most of the existing eucommia ulmoides tea is processed by adopting a green tea process, the grass green taste is heavy, the mouthfeel is bitter, and the palatability is influenced;
(2) The loss of effective components is serious, and the health care function of the product is influenced;
(3) The existing eucommia tea has faint color and turbid soup, and influences appetite and visual impression;
(4) The existing eucommia tea has relatively single function and lacks the traditional Chinese medicine theory support of 'compound compatibility and function superposition'.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides a preparation method of eucommia ulmoides composite functional black tea.
The invention is realized in such a way that the preparation method of the eucommia composite type functional black tea comprises the following steps:
picking fresh folium Eucommiae and cyclocarya paliurus leaf, mixing at a certain proportion, and spreading and drying in the air in a multilayer drying rack; performing enzyme deactivation treatment when folium Eucommiae and cyclocarya paliurus She Weinian; cooling the mixture of the eucommia ulmoides and the cyclocarya paliurus after the green removing to normal temperature, and rolling; twisting until the mixed leaves have the leaf juice leached and are in a strip shape; putting the kneaded mixed leaves of eucommia ulmoides and cyclocarya paliurus into a fermentation machine for fermentation until the leaves are brown; parching the fermented mixed leaves in a drum-type tea parching machine until the leaves are tightly curled and the water is basically eliminated; and (3) placing the fried and dried mixed leaves into a baking machine for continuous baking, and placing the mixed leaves into an aroma raising machine for raising aroma after the moisture of the mixed leaves is completely eliminated. Thus, the composite functional black tea taking the eucommia ulmoides leaves which are homologous in medicine and food as main raw materials is completed.
Further, the preparation method of the eucommia ulmoides composite functional black tea comprises the following steps:
collecting fresh eucommia leaves and fresh cyclocarya paliurus leaves from late 4 months to late 5 months, picking the collected eucommia leaves and cyclocarya paliurus leaves, and removing impurities, branches, yellow leaves and mildewed leaves; ensure the purity, uniform color and uniform appearance of the product.
Step two, uniformly mixing the picked eucommia leaves and the cyclocarya paliurus leaves in proportion, airing the mixed She Zhiyu mesh-shaped multilayer airing rack in a ventilated and dry place until the mixture naturally withers, ensuring the flexibility of raw materials and avoiding the later-stage process of kneading and pressing the raw materials into powder;
step three, performing enzyme deactivation treatment when the shape of the mixed leaves is wilted, ensuring the preservation of effective components and removing the grassy smell of the plant leaves; and (3) when the mixed leaves after enzyme deactivation reach the normal temperature, rolling until the leaf juice is leached out and then forming strips. The effective components of the eucommia ulmoides mixed leaves are broken through rolling, and the eucommia ulmoides mixed leaves have the appearance characteristics of tea leaves primarily;
and step four, putting the twisted mixed leaves into a fermentation machine for fermentation until the color of the eucommia ulmoides mixed leaves is changed into reddish brown. The thearubigin in the mixed leaves of eucommia ulmoides is generated by fermentation, so that the color of the product soup is red and bright. In addition, the grassy smell of the eucommia ulmoides leaf raw material can be further eliminated;
and fifthly, putting the fermented mixed leaves into a drum-type tea frying machine for frying until the tea leaves are curled and compact in appearance and the moisture content is basically eliminated. The repeated collision of tea in the machine through the drum-type tea frying machine makes its mixed leaf of eucommia possess the appearance characteristics of tealeaves completely, can get rid of most moisture in the eucommia tea simultaneously.
And step six, putting the fried and dried mixed leaves into a baking machine for baking. The tea leaves are completely dehydrated by baking, so that the tea leaves are dry and comfortable and are convenient to store.
And seventhly, putting the baked mixed leaves into a fragrance extractor to extract fragrance, and exciting the fragrance to overflow so as to improve the moderate taste of the mixed leaves.
Further, the mixing ratio of the eucommia ulmoides leaves and the cyclocarya paliurus leaves in the step two is 5:1.
further, the spreading and drying thickness of the mixed leaves in the second step is not more than 10cm, and the spreading and drying time is 12 hours.
Further, spreading and airing the mixed leaves in the second step until the moisture content is 40%.
Further, the water-removing temperature in the third step is 140 ℃, and the water-removing time is 25s.
Further, the rolling in the third step is from light to heavy, and the rolling time is 40min.
Further, the fermentation temperature in the fourth step is 40 ℃, the relative humidity is 90 ℃, and the fermentation time is 8 hours.
Further, the frying temperature in the fifth step is 120 ℃, and the frying time is 50min.
Further, the baking temperature in the sixth step is 50 ℃ and the baking time is 6 hours.
Further, the aroma raising time in the seventh step is 6min, and the aroma raising temperature is 110 ℃.
