Abstract:The optimum spray drying conditions for strawberry instant powder were studied.Strawberry was used as raw material to optimize the spray drying technology of instant strawberry powder.Taking the yield of strawberry instant powder as an index，the response surface analysis was carried out according to the design principle of Box-Behnken central composite test for four factors，injection flow rate，β-cyclodextrin content，soluble solid content and air inlet temperature.The results showed that the feed volume 850 mL/h，the addition of beta cyclodextrin 0.7%，the solid content 16%，the inlet air temperature 180 degrees，and the powder extraction rate reached 44.27%.
