| Samenvatting: | This research evaluated the physicochemical properties (proximal analysis, color, apparent content of amylose, and molecular weight of amylose) of native starches from commercial corn (NCS) and unconventional sources apple (NAS) and malanga (NMS). In addition, resistant starches (RS) were obtained from their native sources using the physical treatment of autoclaving and the chemical treatment of acid hydrolysis known as lintnerization. Autoclaved malanga starch (AMS) presented the highest RS content (14 %) compared to all the starches studied. In vitro enzymatic hydrolysis of native and modified starches indicated that autoclaved treatment decreased amylolysis » 24 - 41 % compared to native starches. While with the lintnerization treatment, this reduction was less » 3 - 21 %. The autoclaved and lintnerized treatments reduced the apparent amylose content by » 5 %, producing amylose with lower molecular weights (≈ 80 – 87 kDa) for the autoclaved starches and ≈ 92 – 101 kDa for the lintnerized starches. The luminosity was decreased by the autoclaved treatment and not by the lintnerized process. |
