1-kestose is a trisaccharide and is one of the components of fructooligosaccharide (FOS). Although FOS is a typical non-digestible oligosaccharide with several beneficial health effects that have been clarified, the detailed properties of 1-kestose itself remain unknown. We first determined the digestibility of 1-kestose using rat and human small intestinal homogenates and the inhibition of 1-k...

This paper describes the complementarity of high-performance anion exchange chromatography coupled with pulsed electrochemical detection (HPAEC-PED) and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-TOF-MS) to evaluate commercial available fructans (fructooligosaccharides (FOS) and inulins), having different degrees of polymerization (DP) which are usually employed by foo...

This study was conducted to show the effect of Aspergillus awamori (AA), fructooligosaccharide (FOS), and combined Aspergillus awamori and fructooligosaccharide (AA + FOS) on growth, digestibility, blood parameters, and expression of some growth-related genes. A total of 60 broiler chicks at the age of 15 d were divided into a control group (n = 15) and 3 treatment groups. The control group was...

Also known as a prebiotic, fructooligosaccharide (FOS) resists digestion by gastric acid and pancreatic enzymes in vivo, but is preferentially fermented by beneficial intestinal bacteria once it reaches the colon. While some studies suggest that FOS and its fermentation products may influence the iron absorption process, the effects of prolonged FOS supplementation on iron status remain unclear...

The ?-fructofuranosidase from the yeast Rhodotorula dairenensis (RdINV) produces a mixture of potential prebiotic fructooligosaccharides (FOS) levan-, inulin- and neo-FOS series by transfructosylation sucrose. In this work, gene responsible for activity was characterized its functionality proved in Pichia pastoris. amino acid sequence new protein contained most characteristic elements ?-fructof...

Agro-industrial byproducts possess biotechnological potential due to the presence of bioactive compounds. These have positive metabolic effects, such as reduction risk chronic diseases, inflammation, among others. The cashew apple is one these and stands out for its levels phenolic compounds, flavonoids ascorbic acid, which provide high antioxidant capacity, in addition being an excellent sourc...

Abstract Fructooligosaccharides (FOS) are a type of important prebiotics and produced by transfructosylating enzymes. In this study, sugarcane molasses was used as the substrate for production enzymes Aureobasidium pullulans FRR 5284. NaNO 3 superior nitrogen source to yeast extract A. 5284 decreasing ratio from 1:0 1:1 resulted in reduction total activity 109.8 U/mL 82.5 U/mL. The addition onl...

This study examined the effects of brewers yeast, fructooligosaccharide (FOS), and GroBiotic-A, a mixture of partially autolyzed brewers yeast, dairy components and dried fermentation products, on the intestinal microbial community of red drum, Sciaenops ocellatus. Gastrointestinal (GI) tracts were aseptically removed from three sub-adult red drum previously maintained on a commercial diet and ...

The objectives of this study were to analyze the macronutrients composition, dietary fiber, and resistant starch in Bestak sweet potato variety; to identify the prebiotic components in sweet potato fiber extract (SPFE); and to evaluate the prebiotic activity of SPFE. Evaluation of prebiotic activity was based on the change in cell biomass after 24 h of growth of the probiotic strain in the pres...

Neokestose is a 6G-fructooligosaccharide (FOS) and an important prebiotic. When FOS are ingested by patients with colorectal cancer, they may come into contact with cancer cells prior to being fermented by bifidobacteria in the colon. In the present study, the effects of neokestose on cell proliferation, cell cycle and apoptosis of the colorectal cancer cell line Caco-2 were investigated to eva...
