Valorization of pectins from coffee wastes for the development of pectin-chitosan films.

Coffee wastes are underused materials, largely available in coffee producing regions, which can be used to obtain pectins for the development of films for packaging. Coffee residual water (CRW) provided a phenolic and protein rich-pectic fraction (CRWP), which has 49 % uronic acid. This pectic fraction was used for the development of films with chitosan (Chit).

Fractionation and characterization of cell wall polysaccharides from coffee (Coffea arabica L.) pulp.

Cell wall polysaccharides were isolated by sequential extractions from coffee pulp, the main solid waste from coffee processing. Extractions were conducted with distilled water at room and boiling temperatures, 0.5 % ammonium oxalate and 0.

New findings on acid-extractable pectins from soy hull.

Soy hull has been considered a potential source of commercial pectin. The aim of the present study was to investigate its real potential as a source of pectin. Soy hull (sample 1) was extracted with 0.

Extraction and characterization of a pectin from coffee (Coffea arabica L.) pulp with gelling properties.

About 0.5 ton of coffee pulp is generated for each ton of coffee cherry processed. In the present study, this waste was investigated as a source of pectin.
