Production and molecular characterization of tailored citrus pectin-derived compounds

In this study, tailored-made citrus pectin-derived compounds were produced through controlled enzymatic and/or chemical modifications of commercial pectin with different degrees methylesterification (DM) and similar average molecular weight (MW). the first treatment, degradation (CP) materials by endo-polygalacturonase (EPG) yielded pectins Mw’s (between 2 60 kDa). Separation identification oligosaccharide fraction present in these samples, revealed presence non-methylesterified galacturonic acid oligomers degree polymerization (DP) 1–5. second exploiting combined effect EPG lyase, MW between 21 kDa, containing methylesterified polygalacturonans (DP 1–6), generated. Finally, CP was sequentially modified saponification action EPG. A sample DM 11% 2.7 POS 1–5), produced. Diverse successfully generated for further studies exploring their functionality.
