Synthesis starch stearate with lipase Lipozyme (TL IM) as the catalyst, and potato starch and stearic acid as the reaction substrate, and sodium pyrophosphate as the adjuvant. The effect of substrate ratio, the dosage of sodium pyrophosphate, reaction time on esterification was investigated under the reaction temperature of 65°C, as the dosage of lipase is 10% of starch stearate mass fraction, obtaining the optimum conditions: the mass ratio of starch to stearic acid 3:8, the dosage of sodium pyrophosphate is 25% of starch stearate mass fraction, reaction time, 42h. The degree of substitution of the product was 0.029 under the optimum conditions.
