Induced effects by oxidation with potassium permanganate on the thermal, morphological, colorimetric and pasting properties of corn starch

Abstract: Introduction. Native starches are the most consumed polysaccharides in human diet. They are used in several industries as food, textile, pharmaceutic, etc. However due to some limitations starches should be modified chemically.Materials and methods. Corn starch modified with standard solutions of potassium permanganate (KMnO 4 ) was analysed by simultaneous thermogravimetry-differential thermal analysis, differential scanning calorimetry, rapid viscoamylographic analysis, field emission gun-scanning electron m… Show more

“…The X-ray Diffraction (XRD) analysis was adapted from the methodology proposed in the literature [12,15], using an Ultima 4 (Rigaku, Japan) X-ray diffractometer. CuKα radiation (λ = 1.5418 Å) and settings of 40 kV and 30 mA were used.…”

“…The scattered radiation was detected in the angular range of 5-50º (2Ɵ), with a scanning speed of 2 min -1 and a step of 0.02º. The degree of relative crystallinity was calculated [4,12] from the ratio between peak area and the total diffraction area: Xc = Ap / (Ap + Ab) . 100; where: Xc = relative crystallinity; Ap = peak area; Ab = basis area.…”
