摘要： Carboxymethyl cassava starch was synthesized by an ethanol medium method. Using the SAS/STAT(R) package, the following optimum technological conditions were found: 1:2 (w/w) of monochloroacetic acid to cassava starch, 45 degrees C reaction temperature, 5 hr reaction time and 1: 3(w/v) of solid phase to liquid phase. The product was examined using an infrared spectrometer and scanning electron microscopy. The product has a lower gelatinization temperature, higher clarity, and stronger freezing-thawing stability than native cassava starch. It also has a good water-holding capacity.
