The most abundant DF in wheat bran is AX which can be hydrolysed by special endoxylanases to produce the arabinoxylooligosaccharides (AXOS) [36]. Numerous intervention studies in humans using breads supplemented with AXOS report positive effects on metabolic parameters such as overnight glycemic regulation, gut fermentation measured as breath H2 and circulating SCFA [47]. In particular, the consumption of AXOS-rich breads has been shown to promote…
