Abstract

Starch is one of the most widely used polysaccharides in the food industry to develop and improve products. Depending on its origin, there are different properties such as thickeners, emulsifiers, and gelling agents. Therefore, the objective of this study was to evaluate the technofunctional characteristics of two varieties of quinoa Aurora (VA) and Blanca Dulce (VB). The starch extraction was carried out by the "Water steeping" method, and properties were evaluated: Swelling power (PH), water solubility index (IS), water absorption index (IAA), freeze-thaw stability (ECD), and gelatinization temperature (TG). The VA presented significant differences in relation to the BV, in the following parameters: PH (VA 3,51 g / g ± 0,12; BV 4,08 g / g ± 0,03); IS (VA 1,09 ± 0,15; VB 0,64 ± 0,06); IAA (VA 3,50 ± 0,12; VB 4,07 ± 0,02) and ECD (VA 38,54% ± 0,16; VB 47,79% ± 0,32). While the TG parameter did not present significant differences between the varieties (73,33 ° C ± 1,15). It is concluded that the two starches can be used in processes that require relatively high cooking temperatures; However, the VB can be used in food processes as a thickener for beverages.
