“…The relatively high market prices of XOS products have driven more and more researchers to perform the study of advanced and simple methods for preparing XOS ( 10 ). XOS has been reported to naturally appear in fruits, vegetables, and bamboo shoots; however, the extraction of XOS was very difficult as its concentration in these materials is too low ( 11 ). The XOS products can be produced from lignocellulosic materials rich in xylan by enzymatic or acidic hydrolysis methods ( 5 , 12 ).…”

Since the immune-boosting properties as well as the benefit of promoting the growth of gut bacteria, xylooligosaccharides as prebiotics have attracted considerable interest as functional feed additives around the world. A growing number of studies suggest that acidic hydrolysis is the most cost-effective method for treating xylan materials to prepare xylooligosaccharides, and organic acids were proved to be more preferable. Therefore, in this study, glutamic acid, as an edible and nutritive organic acid, was employed as a catalyst for hydrolyzing xylan materials to prepare xylooligosaccharides. Further, xylooligosaccharide yields were optimized using the response surface methodology with central composite designs. Through the response surface methodology, 28.2 g/L xylooligosaccharides with the desirable degree of polymerization (2–4) at a yield of 40.5 % could be achieved using 4.5% glutamic acid at 163°C for 41 min. Overall, the application of glutamic acid as a catalyst could be a potentially cost-effective method for producing xylooligosaccharides.
