Research of Processing Technology about The Peony Corolla Tea

Researches used drying in the shade,warm air drying,vacuum drying and vacuum freeze drying method to compare the effect of processing technology on peony corolla tea drying. Through the comparison of different processing technology under the water rate,total flavonoid content,rehydration,cell morphology,peony corolla tea appearance and scent,the optimum processing conditions were obtained. The results showed,the flower crown of the peony with vacuum drying and freezing was brightly colored,with the best authenticity,the largest volume and the best water rehydration. The tea made with dried flowers had the best appearance and taste but the content of flavonoids was the lowest. However,the 45 degrees of hot air drying was most effective,with the highest flavonoid content had the better nubrition.
