This paper conveys mainly the application and importance of xylooligosaccharides. The xylooligosaccharides (XOS) are sugar oligomers produced from xylan hydrolysis. The XOS are stable over a wide range of pH and temperatures have the ability of producing lower available energy and significant biological effects at low daily intakes. XOS have a characteristic of prebiotic by promoting the growth of probiotic organisms thus great potential for use in medicines, food and health products. They have various physiological effects such as reducing cholesterol, maintaining the gastrointestinal health and improving the biological availability of calcium, animal feed and anti-cancerous. The driving force of this study was to produce XOS from the organic wastes such as rice bran, citrus peels, corncobs etc. These wastes are rich in xylan which can be used as a renewable material for producing XOS. Because of the yield of toxic byproduct, enzymatic production is mostly preferred. As food ingredients, XOS have an acceptable odour and have low caloric value allowing their utilization in anti-obesity diets. These are noncariogenic, save insulin secretion from the pancreas and stimulate intestinal mineral absorption.
