The organisation of sugar beet and potato cell walls was studied using alkaline extractions following a response surface methodology, simultaneously with solid-state 13 C NMR spectroscopy. The influence of two extraction parameters: NaOH concentration (0.05, 0.275, 0.5M) and temperature (40, 65, 90°C) on the composition (neutral and acidic sugars) of the residues recovered was established...
An experimental design was used to study the influence of different parameters (pH, temperature, time, and type of acid) on extraction of pectins from fresh sugar beet. The extraction conditions have important effects on the features of extracted pectins. Their composition (neutral and acidic sugars, degrees of esterification, amounts of ferulic and diferulic acids) and some physicochemical properties...
