The enzymatic hydrolysates (performed by Termamyl 120Land UEB-S amylase) were analyzed by thin-layer chromatography(TLC). Sugar solution was applied to a precoated silica gel plate(Merck). The chromatoplate was placed in a TLC chamber contain-ing the developing solvent: chloroform/acetic acid/water (6:7:1 byvolume). It was dried under warm air then sprayed with a mixture of ethanol (95%) and H2SO4(5%) and finally heated for 10 min at105◦C to visualize the colored spots.
