The moisture sorption isotherms of apple and citrus pectins using a computerised inverse gas chromatographic (IGC) method were constructed at 25, 30, 40 and 50-degrees-C. Sorption isotherm data are calculated from a single injection of water with the aid of a personal computer and a program developed to perform data handling. Thus sorption isotherms are constructed in < 3 h. Good agreement was observed between moisture sorption isotherms of apple and citrus pectins obtained with the computerised IGC method and the gravimetric static method. (EN)
