Problems solved by technology

The content of active substances such as carotene, amino acid, flavonoids, betaine in the black fruit wolfberry buds is higher than that in the red fruit wolfberry buds, but there is no black fruit wolfberry bud tea made from black fruit wolfberry buds in the prior art
[0004] The traditional tea making method of red fruit bud tea usually adopts the hot air drying method for drying. The disadvantages of hot air drying are: the materials cannot be dispersed, the drying time is long; the thermal efficiency is low, the loss of heat-sensitive nutrients or active ingredients such as vitamins is large, and the product quality not stable enough
