Abstract:Powder processing of fruits and vegetables was one of the methods of comprehensive utilization of fruits and vegetables.Because there were a lot of sugar and sensitive components in fruits and vegetables，the high quality fruit and vegetable powder could not be prepared by ordinary drying methods.Spray drying was a method for the processing of fruit and vegetable powder because of low air temperature and good product properties at present.Spray drying conditions had an important effect on the yield and properties of the fruit and vegetable powder during spray drying.In this article，the factors such as inlet temperature，type and concentration of drying carrier，feed concentration，feed flow rate，drying air flow rate affect the yield and properties of fruit and vegetable powder were reviewed.The causes of the change of yield and properties of fruit and vegetable powder were analyzed.The review would provided references for the powder prepared by spray drying.
