The total XOS yield with optimum ozone dose of 3% (OAAH-3) was found to be 8.9% (w/w biomass) at 110 degrees C in comparison to 7.96% at 170 degrees C by autohydrolysis (AH) alone. Although, there was no significant difference in oligomeric composition (DP 2-6), significant decrease in degradation products namely furfural (2.78-fold), HMF (3.15-fold), acrylamide (nil) and acetic acid (1.06-fold), was observed with OAAH-3 as a pretreatment option. There was 1-fold higher xylan to XOS conversion and OAAH-hydrolysate had higher DPPH radical scavenging activity than AH. PCA plots indicated clear enhancement in XOS production and lower generation of inhibitors with decrease in treatment temperature. Results of the study therefore suggest OAAH can be an effective pretreatment option that can further be integrated with downstream processing for concentration and purification of XOS.10aAdvanced oxidation10aAgro-industry waste10ahydrothermal treatment10aOzonolysis10aXylooligosaccharide1 aSonkar, Rutuja, Murlidhar1 aGade, Pravin, Savata1 aBokade, Vijay1 aMudliar, Sandeep, N.1 aBhatt, Praveena  uhttps://library.ncl.res.in/content/ozone-assisted-autohydrolysis-wheat-bran-enhances-xylooligosaccharide-production-low
