Abstract: 
Purification of glucomannan by hydrolising starch – the main contaminant – was studied. Hydrolysis removed 88.7 % of starch. The highest glucomannan сontent was found to be 73.35 %. The sample showed the comparable infrared spectra to those of the commercial glucomannan. The kinetics of enzymatic hydrolysis was evaluated using the Michaelis-Menten model.
