Glyoxal,organic silane coupling agents,and dodecyl succinic anhydride(DDSA) latex were used to treat tapioca starch individually.When 10 g of starch was mixed with 0.3 g of catalyst,and 4.5 mL of the crosslinking agent for 35 min at 40℃,the crosslinked starch exhibited a rate of water uptake of 19.48% which was less than that of tapioca starch;when starch was 10 g,KH-570 was 8 mL,and the pH was controlled at 8.5,the water uptake ratio of the coupled starch thus-produced was 20.85%;when the volume of DDSA was 7.5 mL,m(DDSA):m(MS-1):m(H2O) was 1:25:46,and the pH was controlled at 8,the water uptake of the esterified starch was 26.62%.After the treatment,the hydrophilicity of the starch was(reduced) because of the decrease of -OH groups,which was validated by FTIR.
