Alternative flours can reveal beneficial health effects. The aim of this study was to evaluate and compare the effects of dietary fibers (DFs) of coconut and carob flours on colonic microbiota compositions and function. Coconut flour DFs were found to be dominated by mannose-containing polysaccharides by gas chromatography (GC)/MS and spectrophotometer, whereas glucose and uronic acid were the main monosaccharide moieties in carob flour DFs.

VKM Ac-1390 (family Microbacteriaceae, class Actinomycetes) contains three rhamnose-containing glycopolymers in the cell wall, the structures of which were established by chemical and NMR spectroscopy methods. The first polymer, a rhamnomannan, consists of repeating tetrasaccharide units with xylopyranose side residues, →2)-α-[β-D-Xyl-(1→3)]-D-Rha-(1→3)-α-D-Man-(1→2)-α-D-Rha-(1→3)-α-D-Man-(1→. The second polymer found in minor amounts, is a rhamnan, →2)-α-D-Rha-(1→3)-α-D-Rha-(1→.

Xylooligosaccharides (XOS) ameliorate insulin resistance (IR) in gestational diabetes mellitus (GDM) probably by propagating Akkermansia muciniphila (Akk). This study aimed to investigate the effects and mechanisms of XOS, Akk and combination on IR in GDM mice/pseudo-germ-free (PGF) mice. Female mice were fed with AIN-93 (n = 19) and high fat diet (HFD) (n = 206).

Xylooligosaccharides (XOS), short-chain polymers with prebiotic properties, have gained significant commercial attention over the past few decades due to their potential as nutraceutical components. Derived from lignocellulosic biomass (LCB), XOS serve as health promoting compounds with applications across multiple sectors, including food pharmaceutical and cosmetic. This comprehensive review provides an overview of XOS production, purification, characterization, and quantification, highlighting their derivation from various sources such as agricultural waste, agro-economical forest residues, and nutrient-dense energy crops.

Naturally derived polysaccharides regulate gut microbiota structure via the gut-liver axis to ameliorate Alcoholic fatty liver disease (AFLD). Acanthopanax seeds are abundant in polysaccharides; however, whether Acanthopanax seed polysaccharides (ASP) improve AFLD through the gut-liver axis remains unclear. In this study, ASP was extracted using ultrasonic-assisted extraction, followed by structural characterization and monosaccharide composition analysis.
