Arabinoxylans (AX) are non-starch polysaccharides from the cell walls of grains. AX are constituted of a linear backbone of xylose units with arabinose substituents and some ferulic acid esterified to arabinose. AX can form gels by oxidative coupling of the phenoxy radicals resulting from the oxidation of ferulic acid. Most bioethanol plants use maize as their main ingredient and the growth of this industry has provided an abundance of co-products such as the dried distillers grains with solubles (DDGS), which can be a source of AX. AX gels are of great interest as controlled release matrices in food, medicine, agronomy and cosmetic industry, among others. In the present study, AX were alkali extracted from DDGS, characterized and gelled and the gel rheological properties and microstructure were investigated. The yield of AX was 4 % (w/w dry basis). These AX presented an arabinose to xylose ratio of 0.61, a ferulic acid content of 0.54 µg/mg AX and a Fourier Transform Infra-Red (FT-IR) spectrum typical of this polysaccharide. AX solution at 2% (w/v) formed gels induced by a laccase as cross-linking agent. Cured AX gels registered storage (G’) and loss (G’’) moduli values of 77 and 0.2 Pa, respectively and a diferulic acid content of 0.20 µg/mg AX. Scanning electron microscopy analysis of the lyophilized AX gel showed that this material resembles that of an imperfect honeycomb. The understanding of DDGS AX yield and characteristics can be useful to propose alternative uses of this co-product. These AX gels could be used as microencapsulation systems for bioactive compounds or cells.
