Problems solved by technology

In the Chinese patent application CN101011092A, the freeze-drying technology is used to control the refire temperature at -10°C-30°C to achieve freeze-drying; however, studies have shown that the freeze-drying technology is below 50°C, and in practical applications, the drying time of materials is too long. It consumes a lot of waste and is extremely low in efficiency, so it is not suitable for industrialization; and the traditional hot air drying refire process, which is dried at 75-85°C for a long time, will easily lead to yellowing of the tea leaves of wintersweet tea and affect the quality of the tea.

Embodiment 1

[0036] A kind of Lamei Longjing tea, its preparation step is as follows:

[0037] 1) Making tea base: use one bud and one leaf or one bud and two leaves of the Longjing tea tree variety in April of that year as raw materials, carry out the green pot according to the frying process of Longjing tea, put the green pot leaves into the extruder, and heat to pressure Up to 5 atmospheres, then reduce the pressure to normal pressure instantly, break the tea cell wall, and then process it into a fragrance-type Longjing green tea, and refine it through a round sieve machine and a winnowing machine to remove the pieces, powder, stems and inclusions in the tea, and control the quality of the tea. Keep the water content below 5% and keep it fresh in the cold storage to get the green tea;

[0038] 2) Fragrance: after the pearl orchid flower in full bloom in May of that year is broken and cleaned, the amount of flowers is calculated according to the percentage by weight of the pearl orchid s...

Abstract

The invention discloses a preparation method of wintersweet longjing tea. The preparation method of the wintersweet longjing tea comprises the following steps: preparing a tea base, blending flavor, scenting, finally scenting, embedding fragrance and re-firing the wet base. According to the preparation method of the wintersweet longjing tea, the longjing tea base is instantly puffed under high pressure to break the wall of the tea base, so that the defect of low adsorption capability caused by a compact structure of pan-fired green tea is overcome, and the physical adsorption capability of efficiently adsorbing wintersweet flower fragrance of the longjing tea base is improved; chloranthus flowers are used as a base by two different manners, the lasting rich fragrance of the chloranthus flowers cooperates and coordinates with the rich fragrance of castanea mollissima fruits in the pan-fired green tea, and thus the fresh and elegant properties of the wintersweet fragrance are well foiled; water of wintersweet flowers is well evaporated while the fragrance is retained to a greatest extent, and the fragrance freshness of the scented tea is improved.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a preparation method of Wintersweet Longjing tea. Background technique [0002] Scented tea is made of green tea, black tea or oolong tea as tea base, with fragrant flowers as raw materials, and made by scenting process. According to the variety of fragrant flowers used, it is divided into jasmine tea, magnolia tea, osmanthus tea, pearl orchid tea, etc. Among them, jasmine tea has the largest output. Gu Yuanqing (1564-1639) of the Ming Dynasty recorded the scenting technology of scented tea in detail in "Tea Methods" in "Tea Spectrum": "Osmanthus osmanthus, jasmine, rose, rose, orchid, orange blossom, gardenia, woody fragrance, Plums can be used as tea." [0003] Wintersweet (Chimonanthus praecox (L.) Link) is a unique resource plant in my country, with high ornamental value, and its traditional application fields are mainly in medicine and cosmetics industries. The fra...
