چکیده

Abstract In this study, the effect of pectin extraction method on properties cellulose nanofibers (CNFs) isolated from sugar beet pulp (SBP) was studied. Pectin extracted by industrially practiced sulfuric acid hydrolysis or enzymatic using a cellulase/xylanase enzymes mixture. The CNFs were then high-pressure homogenization and investigated in terms their chemical composition, crystallinity, size, degree polymerization, re-dispersion water after freeze-drying. mechanical surface characteristics CNF films also results showed that fibrillation de-pectinated SBP more efficient for hydrolyzed SBP. acid-hydrolyzed had slightly wider diameter, higher viscosity, α-cellulose content but lower polymerization than enzyme-hydrolyzed Owing to presence residual hemicelluloses SBP, ability water. displayed better contact angle films.

Effect of extraction conditions on the yield, purity and surface properties of sugar beet pulp pectin extracts

The extraction of pectins from sugar beet pulp was carried out in an aqueous acid medium under different conditions using a full twostate experimental design for three extraction parameters (pH, temperature and time). The yields of the extracted pectins ranged from 4.1% to 16.2%. Their contents in pectin constituents were 35.2–76.3% galacturonic acid, 6.8–32.9% neutral sugars, 2.0–4.2% methoxy ...
