S. aStudy of the effects of ultraviolet light and sodium hypochlorite solutions on properties of Cassava starch granules.h[electronic resource] c2015 aIn this study, samples of native cassava starch were oxidised with standard NaClO solutions (0.1, 0.2 and 0.5 mol L−1) and exposed for 1 h under UV light (UVC radiation with λ=256 nm); they were subsequently filtered, washed, dried and analysed. The thermogravimetric curves showed similar behaviour, with three main mass losses and a decrease in the thermal stability for samples (1) and (3). The oxidative modification performed caused a decrease in the viscosity peaks (RVA), gelatinisation enthalpy (DSC) and relative crystallinity (XRD), and an increase in the average roughness (NC-AFM). The X-ray diffraction powder patterns displayed the BA^ type for all the starch granules. The colour parameters showed a slight increase in the L* value (trend to white) for the treated samples. acassava starch asodium hypochlorite athermal analysis aEspécie Nativa aAmido oxidado aHipoclorito de sódio aLuz ultravioleta aOxidised starch aUltraviolet light1 aGRANZA, A.
