The development of Ganoderma health tea can improve the competitiveness of tea. The Ganoderma health tea processing technology is now briefly introduced. Its technological process: Ganoderma lucidum slice, leaching, filtration, concentration, spray preparation (tea must first retort), drying.
1. Ganoderma lucidum slices: Considering the comprehensive benefits and the utilization of middle and low-grade teas, it is better to use ganoderma lucidum as the raw material in the middle and lower grades. Ganoderma lucidum is washed with clean water and cut into small pieces of about 5 mm in size, ready for use.
2, leaching, filtration: The prepared Ganoderma lucidum fragment, according to 100 g of Ganoderma lucidum added water 1000 ml ratio, placed in 80 °C water bath leaching twice, the first leaching for 1 hour, with filter paper or cotton yarn Filter on the funnel, filter residue for a second leaching, time for 3 hours, and then for filtration, the two filtrates were combined into Ganoderma lucidum water extract.
3. Concentration: Ganoderma lucidum tea extract was placed in a rotary vacuum desiccator, concentrated to 100 ml with a 50-60°C water bath, and cooled as a Ganoderma lucidum tea formulation.
4. Tea revival: Before the preparation of Ganoderma lucidum tea, the tea biscuits should be dried at a temperature of 100°C so as to fully absorb the extracts of Ganoderma lucidum inside and outside the tea bars and maintain the original tea brewing resistance characteristics as much as possible. The moisture content of the green tea after re-firing is controlled below 5%.
5, spray preparation:
(1) Formulation ratio. It is more appropriate to formulate health tea in a ratio of 1:5 between Ganoderma and tea. If Ganoderma lucidum proportion is too large, although the Ganoderma lucidum Gan Xiang is thicker, but the taste is bitter, the taste is poor; if the Ganoderma lucidum proportion is too small, it will lose the Ganoderma lucidum flavor and reduce the health tea effect. In principle, all kinds of tea can be prepared Ganoderma lucidum tea, but more green tea, oolong tea, especially oolong tea preparation of Ganoderma lucidum tea is the best quality, because the taste and aroma of oolong tea can mask some of the bitter taste of Ganoderma lucidum. In addition, to remove the bitter taste of Ganoderma lucidum in Ganoderma Health Tea, it can be added with some licorice, and sugar can also be added during brewing.
(2) Spray mixing. Spray the ganoderma lucidum extract to the tea leaf in two equal proportions by means of a spray tube, ie, press 500 ml of Ganoderma lucidum concentrate to spray 500 g of tea sap, 50 ml each time. After the first spray, wait until the tea is fully absorbed before spraying it a second time.
6, drying: This is the last process, the adsorption of Ganoderma lucidum extract of tea blanks, with 90 ~ 100 °C temperature drying, drying to a moisture content of 5%, after packaging is the finished product of Ganoderma lucidum health tea. The above process is simple and easy, and different varieties of health tea can be developed according to market needs. With some of the Chinese herbal medicines that can be combined with tea, a certain percentage of tea blended with the health tea, as long as it meets the health standards of tea, for example, is already available in the city of honeysuckle tea, ginkgo health tea and so on.
