Abstract：Through different sieves,the carrot powder was divided into different particle sizes of >250 μm, 250 ~1 80 μm,1 80 ~1 50 μm,1 50 ~1 20 μm,1 20 ~1 09 μm,1 09 ~75 μm,<75 μm compared the color, rehydration capacity,oil-holding capacity,the carotene content,total sugar content,the vitamin C content and amino nitrogen content of different particle size of the carrot powder were compared.The results showed that the smaller the particle size of carrot powder,the whiter the powder.They had the trend of becoming darker at first and lighter at last in red,but they were almost the same in yellow.The oil-holding capacity decreased slowly and non-significantly,and the content of carotene,vitamin C decreased significantly,the rehydration capacity and the content of amino nitrogen were higher at first and became lower at last,but the content of total sugar was nearly the same.This showed that carrot powder with different particle size has different physical-chemical properties,so the particle size of carrot powder should be chosen according to the different use of carrot powder.
