Abstract: The granular properties of castanopsis carlesii starch has been studied by using the m odern analytecal techniques suchas electronscan,x -ray diffraction,polarizing microscopyandIodine VoltageAnalyzeretc.The granules of castanopsis carlesii starch shaped regularly,with size f rom5.4μmto 34.5μm,and hqd an obvious maltesecross.Itsx -raydiffractio ngraphappearedasCpattern.Forcastanopsiscarlesiistarch,thegelatinization temperature was from65.5℃to 79.5℃,the amylose content22.83%and the sw ell value and solubility lower.

Key words: castanopsiscarlesii, starch, granular property
