Optimization of reaction condition for carboxylicpropyl starch from potato starch

  • Research Article
  • Published:
International Journal of Plastics Technology

Abstract

Starch from potato was converted to carboxypropyl starch (CPS) by etherification using Monochloropropanoic acid and sodium hydroxide. The reaction was optimized against temperature, concentration and reaction time. The optimizedproduct has a large degree of substitution of 0.734, which compared favorably to other forms of starch. Fourier Transform Infrared spectra were used to characterize the product and potato starch. Digital photographs of starch and product showed the expected amorphous structure while that of the CPS converted beads and smooth surface morphology.
