The synthesis of pectin-silica gels for controlled drug release in gastrointestinal tract (GIT) using low methoxyl (LM) and high methoxy (HM) pectins and tetraethoxysilane (TEOS) as precursor is described. The FTIR spectra of the pectin-silica gels show intense absorption bands at 1246cm-1 and 802cm-1 corresponding to the vibrations COSi bonds, which absent in the FTIR spectra of the native pec...

A three-component Mixture Design was used to investigate the effect of different components of breadcrumbs, textured soy protein (TSP) and low-methoxyl pectin and their interactions on textural properties of an existing fish finger. The result indicated that the pectin had a more notable influence than TSP and breadcrumbs on all textural parameters as pectin proportion increased. At a higher pr...

Pectin is a component of the plant cell and can be found in the primary cell wall and the middle lamella of plant tissues. Currently, pectin is a very important raw material, especially in the food and the pharmaceutical industries. There are several ways to extract pectin from different materials and solvents. One way to synthesize pectin is from the extraction of pomelo peel and this research...

Papaya (Carica papaya L.) peel contains a considerable amount of pectin, high molecular weight polysaccharides that can be used in edible film making due to its ability form gels. However, from pectin usually has poor moisture barrier properties. Therefore, is generally combined with glycerol as plasticizer and starch. This research aimed utilize the addition corn starch determine characteristi...

We report that the most abundant C1 units of terrestrial plants, the methoxyl groups of pectin and lignin, have a unique carbon isotope signature exceptionally depleted in 13C. Plant-derived C1 volatile organic compounds (VOCs) are also anomalously depleted in 13C compared with Cn+1 VOCs. The results confirm that the plant methoxyl pool is the predominant source of biospheric C1 compounds of pl...

This study focused on the isolation and structural characterization of pectin from three distinct species Vietnamese seagrass including Enhalus acoroides, Thalassia hemprichii, Halophila ovalis. The yield obtained acoroides was highest, corresponding to 24.15%, followed by those hemprichii (20.04%) ovalis (19.14%). physicochemical properties total carbohydrate content, anhydrouronic acid (AUA) ...

The objective of this paper was preliminary to extract and characterization purified pectin from lemon wastes. Dry waste extracted applying citric acid solvent or water at various concentrations under a similar condition (85 ºC for 4 h). It found that the highest yield (20.8% dry basis) achieved using hot extraction with an esterification degree 47.8%. contained 63.2 ± 0.74% galacturonic acid, ...

Saba banana, Musa ‘saba’(Musa acuminata x Musa balbisiana) peel is an underutilized waste from processed banana manufacturing in the Philippines. The feasibility of saba banana peel pectin for use in food processing was assessed. Pectin from saba banana peel was extracted under two different extraction conditions. Pectin extraction was carried out using hydrochloric acid (0.5N, pH 1.5) and citr...
