Abstract
The functional and nutraceutical importance of various foods is often attributed to the bioactive molecules present in them. A number of components have been studied but dietary fiber and its different constituents are of prime consideration. Among these, arabinoxylan (AX) and arabinogalactan (AG) are of significant importance in that they hold potential in improving the quality of the baked products along with providing health benefits against various ailments. However, the improvements are dependent on their molecular weights, cross linkages, and solubility. Water-Extractable Arabinoxylan (WEAX) is more effective as compared to Water-Unextractable Arabinoxylan (WUEAX). In this review article, efforts were directed to describe the structural and molecular conformations of these functional ingredients. The discussion has been made regarding the functional properties of AX and AG, for example, improvements in water absorption capacities, dough stability time, and viscosity. They also improve the baking absorption of flour that is positively correlated with bread volume, the most important criterion for stakeholders. The arguments are also provided on the detrimental effects on gluten quality with some possible solutions. Their role in improving the quality and extending the shelf life of bread by reducing the process of staling and retrogradation is the main idea presented in the article. The nutraceutical perspectives were also highlighted as they are helpful in regulating blood cholesterol which thereby protect the body from cardiovascular disorders like atherosclerosis. Additionally, they act as prebiotics for microorganisms residing in the gastrointestinal tract.Keywords
