“…The chemical modification caused a slight increase in the antioxidant capacity of the pectins, which was also reported by Rha et al (2011). This fact corroborates the fact that the antioxidant activity of pectin follows the same behavior of donating electron of phenolic compounds (Serrano-Cruz et al 2013, Haminiuk et al 2012. Indeed, the modification causes the de-esterification of the methyl-ester groups of the samples with an increase in the number of hydroxyls and consequent increase of antioxidant activity.…”

Physicochemical properties of modified citrus pectins extracted from orange pomace

Modified pectin is a polysaccharide rich in galacturonic acid altered by pH adjustment and thermal treatment used especially as an anti-cancer agent. The aim of this work was to study the physical and chemical properties of modified pectins extracted from orange pomace with citric and nitric acids. The galacturonic acid content, degree of esterification, Fourier Transform Infrared Spectroscopy profile, molecular weight, intrinsic viscosity, rheological properties and antioxidant activity of the pectins were evaluated. The modification process caused the de-esterification of pectins and a decrease of molecular weight due to removal of neutral sugars, maintaining the linear chain of galacturonic acid. Such changes also caused a significant increase in the in vitro antioxidant activity (p≤0.05) and influenced the rheological properties of pectin, reducing its viscosity. This work showed that the modification of pectin from orange pomace with citric and nitric acids altered its structural and physical characteristics as well as its biological activity toward a free-radical.

“…The resulting products have an interesting acidity and a bright red color due to the presence of anthocyanins especially delphinidin and cyanidin 3-D-sambubioside (Chang et al, 2012;Cissé et al, 2009;Idham et al, 2012;Março et al, 2011). Their high content in polyphenolic compounds provides them notable antioxidant and free radical scavenging activities (Mohd-Esa et al, 2010;Serrano-Cruz et al, 2013). Currently, the demand for concentrates of H. sabdariffa calyx extracts is increasing for the production of natural dyes.…”

“…In addition to food products CMC is also included in cosmetics, eye drops, lubricants, tablets, coatings etc. The interactions of CMC and polyphenols are currently under study such as the actual research of biogenic activity of polyphenols [2]. It is for example shown that CMC has from all the food industry tested polysaccharides the highest ability to mask the bitter taste of polyphenols and tannins in beverages enriched with antioxidants so that it reduces their astringent effect on the salivary glands [3,4].…”

The aim of this study was to determine release rate and changes in polyphenols’ content, which were sorbed to carboxymethyl cellulose gel and subsequently desorbed. An aqueous extract of blue marc vine variety Fratava was used as a source of polyphenols. The gel was dried into a solid film and polyphenols were then desorbed again by dissolving this film in saline (isotonic) solution. Further, the influence of different times of high temperature (180°C) of drying gel on change in the amount of released polyphenols and also kinetics of their release in re-transfer of the film on the gel and solution was studied. The process simulates the possible use of carboxymethyl cellulose/ polyphenols film sorbed on textile materials and its contact with the tissues and body fluids such as course of wound healing.
