Starch composition determined by IR spectroscopy
Authors

Abstract
In this article, we
determined the composition of starch by IR spectroscopy using the Model-Nexus
spectrophotometer. It has absorption bands between the wavelengths of 3271cm-1
and 398cm-1. Starch is an essential polysaccharide widely used in
the food, pharmaceutical and chemical industries due to its functional and
biodegradable properties. In this study, the chemical structure of starch was
investigated by FTIR spectroscopy, with the aim of identifying the
characteristic functional groups and molecular interactions. The FTIR spectrum
revealed specific bands corresponding to hydroxyl (-OH), ether (C–O–C) and C–H
bonds, confirming the polysaccharide structure of starch. The results
demonstrate that FTIR is a rapid, non-destructive and efficient method for the
qualitative characterization of starch, providing useful information for
quality control and research of starch-based products.
