Title: Detection of Adulterated Maize Starch in Potato Starch by Scanning Electron Microscope and Stable Carbon Isotope Ratio Analysis
Abstract: In order to distinguish the adulteration of edible starch, scanning electron microscope (SEM) and stable carbon isotope ratio (SCIR) analysis were used to qualitatively and semi-quantitatively identify the adulteration of maize starch in potato starch. Due to the difference in microscopic morphology between potato and maize starch granules, the adulterated maize starch granules can be easily distinguished from potato starch granules under SEM. Moreover, the SCIR technology can not only qualitatively discriminate the adulterated maize starch from potato starch, but also determine the content of adulterated maize starch at the condition of higher than 10%. This method can be used as product quality supervision of domestic starch market.
