n the basis of the presented results it can be concluded that accurate chromatographic determination of neutral sugars and galacturonic acid in enzymatically extracted apple pectins and apple pomace must be preceded by two separate acidic hydrolysis (2 M TFA, 2.5 h) conducted at different temperatures. In order to determine the NS profiles, samples should be hydrolysed in milder conditions – 100 °C, whereas a higher temperature – 120 °C, is suitable for GalA determination. Such conditions assure the minimisation of errors resulting from different degrees of neutral sugar degradation or incomplete depolymerisation of polygalacturonic acid. The levels of neutral sugars and galacturonic acid in pectins and apple pomace subjected to the hydrolysis procedure described above amounted to 90% and 73.8%, respectively.
