Title
Comparison of xylo-oligosaccharides production by autohydrolysis of fibers separated from ground corn flour and DDGS
Abstract

•Maximum XOS yield, on xylan basis, from corn flour's fiber was 71.5%.•Maximum XOS yield, on xylan basis, from DDGS fiber was 54.6%.•Corn flour's fiber would be a better feedstock for XOS production than DDGS fiber.

Xylo-oligosaccharides (XOS) are known to have beneficial health properties, and are considered to be functional food ingredients. The objective of this study is to compare corn fibers separated from ground corn flour and distillers dried grains with solubles (DDGS) for XOS yield and optimum autohydrolysis conditions. Based on the initial xylan content, the fiber separated from ground corn flour (FC) resulted in higher XOS yield (71.5%) than the fiber separated from DDGS (FD) (54.6%) at the maximum XOS production conditions. XOS produced were mainly xylobiose and xylotriose. Based on total initial material also, FC resulted in higher XOS yield (8.9%) than FD (8.0%), based on total original masses. Thus, fiber separated from ground corn flour would be a better feedstock for production of XOS than fiber separated from DDGS. The conditions for maximum XOS production from FD and FC were 180 °C with 20 min hold-time and 190 °C with 10 min hold-time, respectively.
