“…The WHC of TPS–FJ and TPS–SC were 7.56 and 9.15 g water g −1 dry polysaccharide, respectively (Table ). The WHC was much higher than those of the isolated acorn polysaccharide (4.33 g water g −1 DM) (Tadayoni et al ., ) and water‐soluble polysaccharides from potatoes peels (4.10 g water g −1 ) (Jeddou et al ., ). Water holding capacity refers to its porous matrix structure and its ability to hold water in its matrix.…”

“…The OHC of TPS–FJ and TPS–SC was 2.84 and 1.31 g oil g −1 dry polysaccharide, respectively (Table ). The OHC is more than the liberty apples fibre concentrates (0.60 g oil g −1 DM), mango dietary fibre (1 g oil g −1 DM) and peach dietary fibre (1.09 g oil g −1 DM) (Figuerola et al ., ; Elleuch et al ., ), but lower than the isolated acorn polysaccharide (5.44 g water g −1 DM) (Tadayoni et al ., ). Ingredients with high oil holding capacity could affect dietary lipid absorption in the gastrointestinal tract and decrease lipid absorption from ingested food.…”

Summary In this study, we compared the chemical structure, antioxidant and immuno‐stimulating activities of two polysaccharides, TPS–FJ and TPS–SC, extracted from Tremella fuciformis from two of the major cultivation regions of China. TPS–FJ and TPS–SC contained protein and high uronic acid. Average molecular weights of TPS–FJ and TPS–SC were 45 461 and 25 981 kDa, respectively. A triple‐helix conformation was exhibited by TPS–FJ but not by TPS–SC. TPS–FJ and TPS–SC contained same monosaccharides but in different ratios. Both the polysaccharides displayed characteristic polysaccharide bands in their Fourier transform infrared and NMR spectra, shown high water and oil holding capacity, and retained antioxidant potential after simulated gastrointestinal digestion in vitro. TPS–FJ significantly (P < 0.05) stimulated the nitric oxide, tumour necrosis factor‐α and interleukin‐6 production of RAW 264.7 cells with higher reactions than those of TPS–SC in vitro. Thus, Tremella fuciformis polysaccharide can be used as a potential antioxidant and immunomodulatory ingredient in food industry.

“…Resistance of acorn polysaccharide powder samples to acidic and enzymatic digestion was determined and compared based n the method of Tadayoni et al [58]. Simulated gastric fluid (SGF; pH 1.2) consisted of NaCl (2 g) and HCl (7 ml) while simulated intestinal fluid (SIF; pH 7.4) included KH 2 PO 4 (6.8 g), NaOH (190 ml) and α-amylase (2 unit/ml) (Sigma-Aldrich).…”

Role of gut microbiome in obesity and type 2 diabetes (T2D) became apparent from several independent studies, indicating that gut microbiome modulators like prebiotics may improve microbiome perturbations (dysbiosis) to ameliorate metabolic derangements. We herein isolate water soluble, non-digestible polysaccharides from five plant based foods (acorn, quinoa, sunflower, pumpkin and sago seeds) and assess their impact on human fecal microbiome and amelioration of high fat diet (HFD)-induced obesity/T2D in mice. During polysaccharide isolation, purification, biochemical and digestion resistance characterization, and fermentation pattern by human fecal microbiome, we select acorn-and sago-derived prebiotics (on the basis of relatively higher purity and yield and lower protein contamination) and examine their effects in comparison to inulin. Prebiotics treatments in human fecal microbiome culture system not only preserve microbial diversity but also appear to foster beneficial bacteria and short-chain fatty acids (SCFAs). Feeding of acorn-and sago-derived prebiotics ameliorates HFD-induced glucose intolerance and insulin resistance in mice, with effects comparatively superior to those seen in inulin-fed mice. Feeding of both of novel prebiotics as well as inulin increases SCFAs levels in the mouse gut. Interestingly, gut hyperpermeability and mucosal inflammatory markers were *

“…Acid is produced during the anaerobic fermentation process, which was assumed to be the cause of the observed pH decrease. In glucose supplemented medium, catabolic repression, since more simple carbon sources are available, results in the production of more acid by the bacteria as compared to the medium with CPSs; the lack of simple carbon sources in this medium, due to the complex chemical structures of the CPSs, results in a longer maintained viability without negatively affecting the growth rate (Tadayoni, Sheikh‐Zeinoddin, & Soleimanian‐Zad, 2015). Our results are in accordance with previously published results in which polysaccharides derived from Gigantochloa levis (Buluh beting) shoots were shown to effectively stimulate the growth of B. animalis ATCC 1053, B. longum BB 536, and L. acidophilus ATCC 4356 as compared to FOS (Azmi et al, 2012).…”

Three polysaccharide fractions from bamboo shoot (Chimonobambusa quadrangularis), CPS70, CPS75, and CPS80, were prepared using a final ethanol concentration of 70%, 75%, and 80% in the precipitation process. In vitro digestibility and the prebiotic activity of CPS70, CPS75, and CPS80 were evaluated and compared. The results indicated that all three of the CPS fractions exhibit a high degree of nondigestibility to human gastric juice (>98.5%) or α‐amylase hydrolysis (>94.5%). Compared with the blank control, the three CPS fractions could not only significantly (p < .05) stimulate the proliferation of B. adolescentis, B. infantis, B. bifidum, and L. acidophilus, but also significantly (p < .05) enhance the production of lactic, acetic, propionic, and butyric acids when these polysaccharides were added as alternative carbon sources to glucose during the in vitro fermentation of four probiotics. Furthermore, when comparing the three CPS fractions, CPS75 displayed the strongest prebiotic potential, as this polysaccharide had the strongest effect on the proliferation of probiotic bacteria as well as the greatest effect on SCFAs production. These results demonstrated that the concentration of ethanol used during the precipitation process has a significant impact on the prebiotic activity of CPS. Practical applications Ethanol precipitation is the first step when extracting polysaccharides from aqueous extracts as it is simple, rapid, and easy to carry out. This study focuses on how different concentrations of ethanol used in the precipitation process affect the prebiotic potential of bamboo shoot (Chimonobambusa quadrangularis) polysaccharides (CPS). The result indicated that the concentration of ethanol used during the precipitation process has a significant impact on the prebiotic activity of CPS. To our knowledge, it is the first to evaluate the effects of the concentration of ethanol during the process of precipitation on prebiotic potential of polysaccharides, which can subsequently be applied to the optimization of ethanol concentration when precipitating natural polysaccharides for the purpose of in vitro fermentation.
