Structural elucidation and in vitro fermentation of extracellular α-d-glucan from Lactobacillus reuteri SK24.003
Publication date: October 2015 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 6, Issue 2 Author(s): Ming Miao, Yajun Ma, Bo Jiang, Steve W. Cui, Shengfang Wu, Tao Zhang The molecular structure and its relationship to in vitro fermentation properties of α-d-glucan from Lactobacillus reuteri SK24.003 were investigated in this study. The chain structure was elucidated by 2D NMR spectroscopy and a possible repeating unit was deduced. During in vitro fecal fermentation, the relatively low initial bacterial population was observed during first 6h incubation and small increase for α-d-glucan for 12–4...

Simulated intestinal hydrolysis of native tapioca starch: understanding the effect of soluble fibre
Publication date: Available online 3 October 2015 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): Hrvoje Fabek, H. Douglas Goff Soluble fibre has been shown to have a reducing effect on plasma glucose levels, which is of particular importance due to the rapidly increasing rates in type 2 diabetes. Researchers speculate that an increase in digesta viscosity is responsible for lowering glucose in the blood; however, the exact mechanism remains to be elucidated. In the present study we examined the effect that adding viscous soluble fibres would have on starch digestibility during simulated intestinal dige...

Barley β-glucan cryogels as encapsulation carriers of proteins: Impact of molecular size on thermo-mechanical and release properties
Publication date: Available online 30 September 2015 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): A. Lazaridou, K. Kritikopoulou, C.G. Biliaderis The potential use of barley β-glucan cryogels as encapsulation carriers for delivery-controlled release of proteins was explored. For cryogel preparation, mixed β-glucan (4.2% w/w) / protein (0.8%) aqueous dispersions were subjected to 10 freezing (−23°C/24h) and thawing (25°C/24h) cycles, using three purified barley β-glucan isolates differing in molecular weight, Mp (55, 140 and 320kDa) and four proteins, selected as model core constituents; i.e....

Short-chain fatty acid profiles from flaxseed dietary fibres after in vitro fermentation of pig colonic digesta: Structure-function relationship
Publication date: Available online 30 September 2015 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): Huihuang H. Ding, Steve W. Cui, H. Douglas Goff, Joshua Gong Flaxseed (Linum usitatissimum L.) is rich in dietary fibres. There are four major soluble dietary fibre fractions, and their molecular structures have been characterised; however, the structure-function relationship on the short-chain fatty acid (SCFA) profiles is still unknown. SCFA profiles produced by in vitro fermentation of pig colonic digesta with soluble flaxseed dietary fibre fractions were determined by gas chromatography with psyl...

Environment induced self-aggregation behavior of κ-carrageenan/lysozyme complex
Publication date: Available online 28 September 2015 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): Wei Xu, Weiping Jin, Chunlan Zhang, Hongshan Liang, Bakht Ramin Shah, Bin Li Self-aggregation behaviors of κ-carrageenan/lysozyme (CRG/Ly) complex inducing by intrinsic and extrinsic factors were investigated form macro and micro aspects, including the ratio, pH, temperature and salt. High Ly content promote aggregation behavior of CRG/Ly complex, while CRG played a suppressive role. Except for CRY5, the complex displayed nano-size distribution. Both CRG addition and the self-aggregation behavio...

The impact of dietary fibres on the physiological processes governing small intestinal digestive processes
Publication date: Available online 28 September 2015 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): Peter I. Chater, Matthew D. Wilcox, Jeffrey P. Pearson, Iain A. Brownlee This review is the second in a series of three articles considering how different types of dietary fibre may affect gut function and health, focusing on the impact of dietary fibre intake on the small intestinal digestive processes. While the small intestinal structure supports the large proportion of gastrointestinal absorption that occurs there, the processes of digestion of macronutrients are largely dependent on the exocrine...

Kiwifruit fermentation drives positive gut microbial and metabolic changes irrespective of initial microbiota composition
Publication date: Available online 15 July 2015 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): Paul Blatchford, Halina Stoklosinski, Gemma Walton, Jonathan Swann, Glenn Gibson, Richard Gearry, Juliet Ansell It is well established that individuals vary greatly in the composition of their core microbiota. Despite differing ecology, we show here that metabolic capacity converges under the pressure of kiwifruit substrates in a model gut system. The impact of pre-digested green and gold kiwifruit on the human colonic microbiota and their metabolic products was assessed using in vitro, pH-controlle...

Characterisation and in vitro fermentation of resistant maltodextrins using Human faecal inoculum and analysis of bacterial enzymes present
Publication date: Available online 17 July 2015 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): Christiane Rösch, Koen Venema, Harry Gruppen, Henk A. Schols A commercially available resistant maltodextrin (RMD), which is made out of corn starch by chemically and enzymatically modification, consists of atypical starch linkages and a low average molecular mass of 2kDa. These characteristics of RMD make it rather complicated to identify with any chromatographic or masspectrometric method at this moment. A batch fermentation with human inocula over 48hours under anaerobic conditions showed that the deg...
