Xylooligosaccharides as prebiotics from agricultural by-products: Production and applications
Publication date: Available online 5 January 2015 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): A.K. Samanta , Natasha Jayapal , C. Jayaram , Sohini Roy , A.P. Kolte , S. Senani , Manpal Sridhar The growing demands of novel food products for well-being and age related issues coupled with increasing health care expenditure has attracted global attention on prebiotics. During the end of twentieth century, a great concern was expressed for transfer of antibiotic resistance genes from animal to human through food chains leading to the concept of “preventive medication”. Xylooligosaccharides (XOS) i...

Guluronate oligosaccharides as enhancers of nanoparticle drug delivery in the oral cavity
Publication date: Available online 31 December 2014 Source:Bioactive Carbohydrates and Dietary Fibre Author(s): Catherine Taylor Nordgård , Astrid Bjørkøy , Kurt I. Draget Guluronate oligomers have been shown to modify the gastrointestinal mucus barrier and improve nanoparticle penetration. Here we investigate the effect of guluronate oligomers on nanoparticle mobility in saliva, a central extracellular barrier in the oral cavity. Guluronate oligomers reduced nanoparticle aggregation in saliva and improved nanoparticle mobility over and above that which would be expected to result from the decrease in size. As su...

Direct in-vitro assay of resistant starch in phosphorylated cross-linked starch
The objective of this study was to develop a method to solubilize the RS fraction in phosphorylated (0.4% phosphorus) CL wheat starch (RS4) after its incubation with α-amylase and amyloglucosidase for 16h at 37°C as directed by the RS assay AOAC Method 2002.02. The residue was hydrolyzed and solubilized by conducting two back-to-back incubations with thermostable α-amylase for 30min at 100°C and pH 5.0, cooling to 50°C, then incubating quickly with amyloglucosidase at 50°C for 1h at pH 5.0. Importantly, the cooling process after α-amylase incubation was done by placing the mixture in a water bath at 50°C. The degre...

Physicochemical and antioxidant properties of dietary fibers from Qingke (hull-less barley) flour as affected by ultrafine grinding
Publication date: October 2014 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 4, Issue 2 Author(s): Bin Du , Fengmei Zhu , Baojun Xu The effect of particle size of Qingke flour and particle size of dietary fiber (DF) on physicochemical and antioxidant capacities of DF was investigated. Qingke and extracted DF were ground by regular and ultrafine grinding and their particle sizes were determined using laser diffraction method. The results indicated that ultrafine grinding could effectively pulverize DF particles to submicron scale; the particle size distribution was close to a Gaussian distribution. The sol...

Non-digestible long chain beta-glucans as novel prebiotics
Publication date: July 2013 Source:Bioactive Carbohydrates and Dietary Fibre, Volume 2, Issue 1 Author(s): Ka-Lung Lam , Peter Chi-Keung Cheung As our understanding of host gut microbiome increases, research interests in the fields of prebiotics, probiotics and synbiotics are growing rapidly. Currently, the majority of prebiotics in the markets are derived from non-digestible oligosaccharides. Very few investigations have been focused on non-digestible long chain complex carbohydrates/polysaccharides for their potential as novel prebiotics. One of the reasons behind this is the unavailability of non-digestible polysa...
