[0025] The invention provides a preparation method of Gynostemma pentaphyllum tea for removing bitterness and coldness, comprising the following steps:
[0026] 1) separating the Gynostemma stems and leaves harvested from late September to October, and killing the obtained Gynostemma stems and Gynostemma leaves respectively, to obtain the Gynostemma stems and Gynostemma leaves that have been fixed;
[0027] 2) Carrying out the heaping and dehydration of the dried Gynostemma stems and Gynostemma leaves of the step 1) respectively, to obtain dehydrated Gynostemma stems and dehydrated Gynostemma leaves;
[0028] 3) Cut and sieve the dehydrated Gynostemma stems and dehydrated Gynostemma leaves in step 2) respectively, mix the sieved dehydrated Gynostemma stem cuttings and dehydrated Gynostemma leaf cuttings to obtain Gynostemma scraps, and cut the Gynostemma stems , cutting the Gynostemma gynostemma leaves and the Gynostemma pentaphylla scraps to soften respectively to obtain the ...
Embodiment 1
[0044] The stems and leaves of Gynostemma pentaphyllum were separated, the stems of Gynostemma pentaphyllum were blanched in circulating hot water at 90°C for 3 minutes to kill green, and the leaves of Gynostemma pentaphyllum were steamed at 110°C for 90s. After killing greens, pile the stems of Gynostemma pentaphyllum for 24 hours, dehydrate at 60° C. for 4 hours, then cool down to 55° C. and dehydrate for 15 hours to obtain dehydrated Gynostemma pentaphyllum stems. Knead the Gynostemma Gynostemma leaves, and pile them up for 12 hours after kneading. Dehydrate the piled Gynostemma pentaphyllum leaves at 60° C. for 4 hours, and then cool down to 55° C. for 15 hours to obtain dehydrated Gynostemma pentaphyllum leaves. Cut the obtained dehydrated Gynostemma stems and leaves into 2.5cm stem segments respectively, and mix the sieved scraps at the same time to obtain Gynostemma Gynostemma scraps. The cut Gynostemma stems were steamed at 110° C. for 9 minutes to soften them to obta...
Embodiment 2
[0046] In late September, the above-ground stems and leaves of Gynostemma pentaphyllum were picked in southern Shaanxi, the stems and leaves of Gynostemma pentaphylla were cleaned, and the stems and leaves were separated. The stems of Gynostemma pentaphyllum were scalded in circulating hot water at 95°C for 2 minutes to complete greening, and the leaves of Gynostemma pentaphyllum were steamed at 120°C for 30s. After killing greens, the stems of Gynostemma pentaphyllum were piled up for 12 hours, dehydrated at 55° C. for 5 hours, and then cooled to 45° C. for 20 hours to obtain dehydrated Gynostemma pentaphyllum stems. Knead the leaves of Gynostemma pentaphyllum, after kneading, stack them for 24 hours, dehydrate the piled Gynostemma leaves at 55° C. for 5 hours, then cool down to 45° C. and dehydrate them for 20 hours to obtain dehydrated Gynostemma pentaphyllum leaves.
