Abstract: Effects of forced-air drying and microwave drying on flavonoids of the You Jujube were studied in this paper. Theresult shows that the optimum condition of forced-air drying is drying air temperature at 40℃, drying time for 8h and drying loadof 15kg/m2; the optimum condition of microwave drying is microwave power of 0.245 kW, drying time for 10 minutes and dryingload of 5kg/ m2.

Key words: you jujube, flavonosd, forced-air dringy, microwave drying
