WebPurified freeze-dried fractions of hemicelluloses and pectins, of different molecular weights, were obtained by treating hydrothermal extracts (140, 160, and 180 °C) of discarded carrots with... Weboily substances, hemicellulose, pectin and lignin. These impurities prevent the interaction between cellulosic hydroxyl groups and polymer matrices and are responsible for poor interfacial interactions between the fibers and the matrix, which later leads to debonding and void formation. The impurities present on fibers surfaces can be

WebHence, this study investigated microwave-assisted extraction (MAE) optimisation to extract pectin from pineapple (Ananas comosus) peel. Microwave power (400–600 W), pH (1.5–2.5), and solid-to-liquid (S/L) ratio (1:10–1:30 w/v) were applied to optimise pineapple peel pectin (PPP) extraction, as well as to determine the interaction effects… WebDensity increased marginally with treatment due to removal of lighter constituents of the flax fiber like hemicellulose and pectin. Treatment had a positive influence on the tensile and interfacial adhesion strengths of the fibers. However, treatment with stearic acid yielded superior values of mechanical properties in comparison to KMnO 4. pink quilt background
