Abstract: A micromethod for determination of the esterification degree of pectin by means of infrared spectroscopy was elaborated. Absorbances in KBr discs were measured in the vas(COO~) and v(C = 0) es ter regions at 1605 and 1745 cm-1, respectively. The error of determination of the esterification degree of pectin did not exceed ± 3 % .
