| Abstract: | Stearostarch was prepared by means of transesterification of the hydrolytic derivatives with methyl stearate in water in the presence of K2CO3 as catalyst. The relationship between the degree of esterification of stearostarch obtained and the DP of starch hydrolysed, concentrations of methyl stearate and catalyst as well as the reaction temperature and time are discussed. |

| Keywords: | tarch hydrolysis derivatives stearostarch transestification with water as a solvent degree of esterification |
