All bread samples exhibited bright color like the control. Initial texture of bread made from the various resistant starches was tender but with storage, a general increase in the hardness of the bread was noticed. This was attributed to the ability of guar gum to absorb water and the association between the guar gum and emulsifier with the gluten and lipid of the bread flour.

In this report, half-esterification between these pendent hydroxyl groups of hydroxyl-PU and maleic anhydride could lead to new pendent groups, carboxylic groups. These highly polar carboxylic groups in the side chain of PU could play the role of internal emulsifier. They had self-dissociation ability in the water or were neutralized first by appropriate amount of base. Then, PU bearing carboxylic group could dispersed steadily in the water, named aqueous-based polyurethane dispersion.
