Current status of xylooligosaccharides : production, characterization, health benefits and food application
2021
BACKGROUND : Functional foods are receiving high interest and attracting global attention due to their therapeutic health benefits. Xylooligosaccharides (XOS) are potential prebiotics that has attained commercial interest due to their prospective application in the food industry and its beneficial effects on human wellness. The demand to create alternate natural sources is steadily increasing to meet the consumer and industry needs for safe foods. SCOPE AND APPROACH : The review summarizes the various strategies employed in xylan extraction, XOS production (chemical and enzymatic) and characterization. The study also critically views the physiological importance and biological effects described through various in vitro and in vivo intervention studies. The technological properties, food-based applications and the future perspectives of XOS are presented. KEY FINDINGS AND CONSLUSIONS : A better utilization of XOS to exert a positive impact on health would help to the functional foods and nutraceuticals future markets.
