Whole grain rice is a rich source of fiber, nutrients, and phytochemicals that may promote gastrointestinal health, but such beneficial components are typically removed with the bran during polishing. Soluble feruloylated arabinoxylan oligosaccharides (FAXO) and polyphenols (RBPP) isolated from rice bran are hypothesized to have positive impacts on human gut microbiota through a prebiotic function. Using an in vitro human fecal fermentation bioassay, FAXO and RBPP treatments were assessed for short-chain fatty acids (SCFA) production patterns and by evaluating their impacts on the phylogentic composition of human gut microbiota by 16S rRNA gene sequencing...

Patients with chronic pancreatitis (CP) present malabsorption and changes in nutritional status. In this prospective, randomized, controlled, double-blinded, intervention study, developed at the Clinic of Pancreas, we aimed to assess whether the use of symbiotics changes the nutritional status, the biochemical data and the intestinal rate of these patients. The intervention consisted of administering 12 g/day of symbiotics composed of Lactobacillus casei, Lactobacillus rhamnosus, Lactobacillus acidophilus, Bifidobacterium bifidum and fructooligosaccharides to the intervention group and 12 g/day of medium absorption complex carbohydrate to the control group...

Yacon (Smallanthus sonchifolius) originates from the Andean region and has spread across South America, Europe and Japan. In contrast with most roots, yacon stores its carbohydrates in fructooligosaccharides (FOS) and contains approximately 37% of FOS in its root dry matter. Aqueous extracts of yacon were characterized through TLC, methylation, NMR, and ESI-MS. FOS of yacon showed as linear fructooligosaccharides containing almost exclusively (2→1)-linked β-fructofuranosyl units, with terminal α-glucopyranosyl and β-fructofuranosyl units...

BACKGROUND: Atopic dermatitis (AD) is recently increasing among populations, but the underlying mechanisms remain controversial. Interactions between the gut microbiota and mucosal immunity are considered to be a crucial etiology. Fructooligosaccharide (FOS), prebiotics have been reported as activators of the gut microbiota. OBJECTIVE: The aim of this study was to investigate the effects of kestose, the smallest FOS and FOS on atopic dermatitis in mice. METHODS: An AD mouse model was developed by (ovalbumin) epidermal sensitization using BALB/c mice...

Fructooligosaccharides (FOS) and inulin, composed of β-2-1 linked fructose units, have a broad range of industrial applications. They are known to have various beneficial health effects and therefore have broad application potential in nutrition. For (modified) inulin also for non-food purposes more applications are arising. Examples are carboxymethylated inulin as anti-scalant and carboymlated inulin as emulsifiers. Various plants synthesize FOS and/or inulin type of fructans. However, isolating of FOS and inulin from plants is challenging due to for instance varying chains length...

Oligosaccharides are polymers with two to ten monosaccharide residues which have sweetener functions and sensory characteristics, in addition to exerting physiological effects on human health. The ones called nondigestible exhibit a prebiotic behavior being fermented by colonic microflora or stimulating the growth of beneficial bacteria, playing roles in the immune system, protecting against cancer, and preventing cardiovascular and metabolic issues. The global prebiotics market is expected to grow around 12...

A hydrophilic interaction liquid chromatography (HILIC) stationary phase was prepared by a two-step synthesis method, immobilizing polyacrylamide on silica sphere particles. The stationary phase (named PA, 5μm dia) was evaluated using a mixture of carbohydrates in HILIC mode and the column efficiency reached 121,000Nm(-1). The retention behavior of carbohydrates on PA stationary phase was investigated with three different organic solvents (acetonitrile, ethanol and methanol) employed as the weak eluent. The strongest hydrophilicity of PA stationary phase was observed in both acetonitrile and methanol as the weak eluent, when compared with another two amide stationary phases...

Composition of the gut microbiome is influenced by diet. Milk or formula oligosaccharides act as prebiotics, bioactives that promote the growth of beneficial gut microbes. The influence of prebiotics on microbial interactions is not well understood. Here we investigated the transformation of prebiotics by a consortium of four representative species of the infant gut microbiome, and how their interactions changed with dietary substrates. First, we optimized a culture medium resembling certain infant gut parameters...

We describe here the enzymatic production of levan type-fructooligosaccharides (L-FOS) with a DP from 2 to 10, through simultaneous synthesis and hydrolysis reactions. This was accomplished by LevB1SacB, a new enzyme resulting from the fusion of SacB, a levansucrase from Bacillus subtilis and LevB1, an endolevanase from B. licheniformis. In the fusion enzyme, SacB retains its catalytic behavior with a decrease in kcat from 164 to 108s(-1). LevB1 in LevB1SacB kinetic behavior improves considerably reaching saturation with levan and following Michaelis-Menten kinetics, quite differently from the previously reported first order kinetic behavior...

We investigated the effects of dietary supplementation of difructose anhydride III (DFA III), raffinose (Raf), and fructooligosaccharides (FOS) on diet-induced obesity development. Male rats were fed normal or high-fat and high-sucrose (HFS) diet, with or without supplementing (3%) DFA III, Raf, or FOS, for 8 or 5 weeks. Supplementing DFA III to the HFS diet decreased energy intake compared to the non-supplemented HFS diet. Accordingly, body weight gain and fat accumulation reduced in DFA III-fed rats. Cecal acetate production and plasma glucagon-like peptide-1 (GLP-1) and peptide-YY (PYY) were elevated in DFA III-fed rats, while Raf and FOS partially affected these parameters...

The bacterial groups in the gut ecosystem play key role in the maintenance of host's metabolic and structural functionality. The gut microbiota enhances digestion processing, helps in digestion of complex substances, synthesizes beneficial bioactive compounds, enhances bioavailability of minerals, impedes growth of pathogenic microbes, and prevents various diseases. It is, therefore, desirable to have an adequate intake of prebiotic biomolecules, which promote favorable modulation of intestinal microflora. Prebiotics are non-digestible and chemically stable structures that significantly enhance growth and functionality of gut microflora...
