“…However, this method may be suitable for the proposed integration, since the pH that is required for HG pectin extraction is lower compared to alkaline extraction, by which pectin product can be extracted separately with no extra salts generated. Enzymes can be used to aid GA extraction by hydrolyzing pectin into GA (Su et al, 2015) or by hydrolyzing cell wall carbohydrates (Wikiera et al, 2015). Pectate lyase and/or pectinase can be used for hydrolysis of pectin, while galactanase, arabinanase, hemi-celllulase and cellulase are often used for the degradation of cell wall carbohydrates, including rhamnogalacturonan I pectin, hemi-cellulose and cellulose (Taherzadeh and Karimi, 2008).…”

“…Raw polysaccharide extracts have been shown to possess the higher antioxidant activity than purified extracts [15]. The antioxidant activity of pectins was suggested to be increased by nonpectin contaminants (phenols and proteins) that were coextracted with them [16,17]. Therefore, investigating the capacity of the digestive process to release antioxidant crude pectic polysaccharides from plant cell wall matrix (i.e., bioaccessibility) is of great interest and is a first step in the determination of the beneficial potential of vegetable-based food.…”

The antioxidant properties of vegetable pectin fractions against intraluminal reactive oxygen species were elucidated in vitro in conjunction with their structural features. The pectin fractions were isolated using a simulated gastric fluid (pH 1.5, pepsin 0.5 g/L, 37 ∘ C, 4 h) from fresh white cabbage, carrot, onion, and sweet pepper. The fraction from onion was found to inhibit the production of superoxide radicals by inhibiting the xanthine oxidase. The high molecular weight of onion pectin and a large number of galactose residues in its side chains appeared to participate in interaction with xanthine oxidase. All the isolated pectic polysaccharides were found to be associated with protein (2-9%) and phenolics (0.5-0.7%) as contaminants; these contaminants were shown to be responsible for the antioxidant effect of vegetable pectin fractions against the hydroxyl and 1,1-diphenyl-2-picrylhydrazyl radicals.

Abstract" prebiotic is a selectively fermented ingredient that results in specific changes in the composition and/or activity of the gastrointestinal microbiota, thus conferring benefit s upon host health. The most widely accepted prebiotics are lactulose, inulin, fructooligosaccharides FOS , galactooligosaccharides GOS , and the human milk oligosaccharides HMO . However, there is a growing list of potential prebiotics although the evidence for these, especially in humans, is not as well established as for FOS and GOS. Some of them are already commercialized but others such as polydextrose PDX , pectic oligosaccharides POS , bacterial exopolysaccharides EPS , polysaccharides derived from algae and sugar alcohols are still in the early stages of development. This chapter summarizes the scientific literature regarding the manufacture and the evaluation of the properties of this group emerging prebiotics . Keywords: emerging prebiotics, pectic oligosaccharides, polydextrose, algae-derived oligosaccharides, bacterial exopolysaccharides, sugar alcohols . IntroductionThe consumption of prebiotics is being specially considered as a good health-improving strategy they have been recently defined as nondigestible compounds that through its metabolization by microorganisms in the gut, modulate the composition and/or the activity of the gut microbiota, thus conferring physiological benefit effects on the host health [ ].The microbial communities that inhabit the human intestinal tract constitute a complex association, comprising more than species and around microorganisms, mainly anaerobic > . % . levels of microorganisms and the main bacterial groups. "long the jejunum, and particularly in the ileum, there is a gradual increase in the number and diversity of bacteria, and finally, the majority of gastrointestinal microbes are housed in the colon [ ]. However, scientific works on this field suggest that the gut microbiota is not only a simply collection of microorganisms, but also reflects an interrelationship between the different groups that might work together for the benefit of the host [ ]. In addition, the microbiota also establishes a close symbiosis with the host humans provide the nutrients and the appropriate conditions for its development, and it performs three essential primary functions metabolic, trophic, and defensive [ ]. In fact, there is a long list of pathologies which are linked to the alteration of the gut microbiota, including hepatic encephalopathy, diarrhea, diabetes, obesity, colon cancer, I"S, I"D, gastrointestinal infections, and necrotizing enterocolitis [ , ].The composition of the gut microbiota is influenced by a variety of factors that include i the microbial species which are acquired at birth, ii host genetics, iii age [ ], iv diseases and antibiotic usage [ , ], v the stress [ ], and vi the diet. In fact, the diet is probably the most important factor and several studies are focused on the modulation of the gut microbiota by the consumption of functional foods, such as prebiotics [ ].For c...
