“…Only a few compounds DOI: 10.1002/mnfr.202200171 of the carbohydrate group, such as inulin, fructooligosaccharide (FOS), galactooligosaccharide (GOS), xylooligosaccharides (XOS), and isomaltose oligosaccharides (IMO). [1,2] XOS, nondigestible oligosaccharides, is a kind of emergent prebiotic composed of 2-7 D-xylose units with 𝛽-1,4 glycoside bonds, [3,4] which are generally regarded as safe by FDA. And there are more research focusing on XOS because of its efficiency and unique effects on improving inflammatory.…”

Xylo‐oligosaccharides (XOS) has a bidirectional regulatory effect, and can be fermented by gut microbiota. This study aims to investigate how XOS alleviates Folium Sennae extracts induced diarrhea in mice. KM mice are given different concentration XOS for 3 weeks, and then Folium Sennae (Senna alexandrina Mill) extracts solutions (0.8 g mL−1) are given to establish diarrhea model. The results show that doses of XOS at 0.25 mg g−1 BW day−1 and higher could alleviate diarrhea symptoms by decreasing the disease activity indexes, down‐regulating pro‐inflammatory factors, up‐regulating anti‐inflammatory factor, and suppressing the intestinal permeability in colon tissues. XOS also regulates the composition of gut microbiota via increasing the abundance Prevotellaceae, Ruminococcus, and Bifidobacterium. The results suggest that the dietary supplementation XOS could be a more effective choice to prevent and alleviate diarrhea.

“…Currently, XOS derived from xylan-containing lignocellulosic biomass is widely used in food, chemical, pharmaceutical, feed, and nutraceutical industries [ 5 , 6 , 7 ]. Although, many different approaches have been reported for XOS production from various sources of biomass, the most effective method employs xylanase to hydrolyze xylan, the main component of hemicellulose [ 7 , 8 ]. This method is not only environmentally friendly, but also produces the main functional components, xylobiose (X2) and xylotriose (X3) [ 7 ].…”

“…Thus, the enzymatic degradation of hemicellulose in Jiuzao to produce XOS should be possible. However, any such new production process must overcome two problems that limit the accessibility of components to hydrolytic enzymes: the strong crystalline structure of the cellulose, and the complex structure crosslinking lignin and hemicellulose with cellulose in Jiuzao [ 7 , 9 ]. Effective pretreatments are needed to disrupt the crystalline structure of cellulose and increase hemicellulose exposure to hydrolytic enzymes thereby increasing the efficiency of enzymatic hydrolysis and XOS yield [ 10 , 11 ].…”

The production of xylooligosaccharides (XOS) from Jiuzao was studied using a two-stage process based on autohydrolysis pretreatment followed by enzymatic hydrolysis. Jiuzao was autohydrolyzed under conditions where temperature, time, particle size, and solid-liquid ratio were varied experimentally. Optimal XOS production was obtained from Jiuzao with a >20 mesh particle size treated at 181.5 °C for 20 min with a 1:13.6 solid-liquid ratio. Subsequently, optimal enzymatic hydrolysis conditions for xylanase XynAR were identified as 60 °C, pH 5, and xylanase XynAR loading of 15 U/mL. Using these conditions, a yield of 34.2% XOS was obtained from Jiuzao within 2 h. The process developed in the present study could enable effective and ecofriendly industrial production of XOS from Jiuzao.

“…It was reported that the risk of vascular instances has been reduced due to the regular consumption of prebiotic (Harris & Kris‐Etherton, 2010). For example, fructooligosaccharides showed potential health benefits, such as the ability to improve the gastrointestinal condition, constipation reduction, mineral uptake enhancement (Palaniappan et al, 2021). Methods for converting hemicellulose to XOS are highly dependent on the source material, and pretreatment is a frequent step to extract xylan from biomass (Anak et al, 2016; Tsutomu et al, 2018).…”

This study was to produce functional xylo‐oligosaccharides (XOS) from wheat bran via ultrasonic‐assisted extraction, enzymatic hydrolysis, and purification. Optimal extraction conditions were ultrasonic frequency of 72 kHz, sonication time of 20 min, solid/liquid ratio of 1:21(w/v), 100°C, and extraction time of 2.25 h. Under these conditions, XOS extraction rate of 60.27% was obtained. Optimal enzymatic hydrolysis conditions were 10% for substrate concentration, 800 U/g for enzyme concentration, 55°C, and 4 h for hydrolysis time. Under these conditions, a hydrolysate with 25.52% of XOS content, DP = 2.68. In addition, the hydrolysate solution was decolorized using anion‐exchange resin D392 and the highest decolorization rate (89.26%) was obtained at elution volume of 1 ml/min and 50°C. Decolorized XOS hydrolysate was purified using cation‐exchange resin under optimized conditions of 1.5 ml/min elution volume, 11 ml injection volume, and 35% concentration at 75°C. The concentration of XOS increased from 64.41% to 75.63% after purification.
