Abstract Each day huge amount of plants are consumed, thereby a lot of by-products are dumped into the ashcan directly which are rich in highly nutritious bioactive substances: dietary fiber (DF). DF, defined as the seventh nutrient for humans by nutritionists, has many benefits for our health, such as improve the intestinal flora, decrease the probability of obesity and cardiovascular disease, etc. Thus the study on the modification of plant DF to obtain the high yield and quality DFs (includin...

Abstract This paper investigates the potential of composite gels, formed by the pH-treated whey protein isolation (WPI) and Mesona chinensis polysaccharides (MCP) solutions, as jelly processing ingredients. The functional, gelation properties, and microstructure of MCP-WPI gels were investigated under specific conditions (pH 4-10). The results showed that MCP and WPI can form a stable gel under the condition of pH 10, ζ-potential increased and the particle size decreased with the increase of pH....

Abstract null null The chemical compounds including lipid and protein in green coffee beans are important indicators of the final quality of the coffee products, which are usually determined by time-consuming and destructive chemical methods. Therefore, a fast and reliable method was attempted to exploit by near-infrared (NIR) spectroscopy combined with partial least squares (PLS) regression for the determination of lipid and protein in green coffee beans from different origins. Orthogonal signa...

Abstract null null Increasingly attention has been paid to the active substances in grapefruit peel. In this study, insoluble bound phenolic compounds (BP) were released from grapefruit peel insoluble dietary fiber (GP-IDF) by microwave extraction (M-BP), enzymatic hydrolysis (E-BP) and combined microwave and enzymatic treatment (ME-BP). The results showed that the yield of ME-BP was the highest (148.856 ± 0.620 GAE mg/100 g), and conditions of microwave treatment (microwave power, temperature, ...

Abstract The previous research has indicated that Ganoderma atrum polysaccharide (PSG-1) indirectly affects the immune function of dendritic cells (DCs) in intestinal-like Caco-2/DCs co-culture model, in which NF-κB and MAPK pathway play an essential role. To explore the interaction of Caco-2 in the interaction between the intestinal epithelium and its internal immune cells, the intestinal-like Caco-2/DCs co-culture model was developed. All transcripts of Caco-2 treated with or without PSG-1 wer...

Abstract The research aimed to assess the effects of high-temperature cooking assisted enzymatic method on the structural, physicochemical and functional properties of soluble dietary fiber (SDF) from tea residue (GM-SDF). Under the optimal extraction conditions obtained by response surface methodology, the GM-SDF yield was significantly higher than that of untreated tea residue (U-SDF). It could be found results showed that GM-SDF possessed more hydrophilic groups, higher crystallinity, as well...

Abstract With application of PLS regression and SVR, quantitation models of near infrared diffuse reflectance spectroscopy were established for the first time to predict the content of volatile basic nitrogen (TVB-N) content in beef and pork. Results indicated that the best PLS model based on the raw spectra showed an excellent prediction performance with a high value of correlation coefficient at 0.9366 and a low root-mean-square error of prediction value of 3.15, and none of those pretreatment...

Abstract Carrot powder digestion was researched utilizing an in vitro standardized static model associated with an in vitro colonic fermentation method to analyze the recovery, catabolism, and potential bioactivity of polyphenols from carrot. Twenty-seven polyphenols and their metabolites (hydroxybenzoic acids, hydroxycinnamic acids and its derivatives, etc.) were identified in samples before and after digestion/colonic fermentation, and the possible colonic pathways for major polyphenols were p...

This study is aimed at exploring the release of bound polyphenols (BP) from insoluble dietary fiber (IDF) and its mechanism by solid-state fermentation (SSF) via Trichoderma viride. The results indicated that BP released by SSF (5.55 mg GAE/g DW) was significantly higher than by alkaline hydrolysis. In addition, 39 polyphenols and catabolites were detected, and the related biotransformation pathways were speculated. Quantitative analysis showed that SSF released more ferulic acid, p-coumaric aci...
