Abstract – Detection of adulterants in food products is mandatory to ensure that the food we consume is of good quality. In case the adulterant is not detected properly, it leads to various health hazards and fatal diseases. This project focuses on analysing the presence of adulterants in chilli powder, one of the most commonly used ingredient in our household. The common adulterants used in chilli powder are Red lead salt, Sudan dyes, Brick powder etc,. Conventionally chemical tests were being conducted to detect these chemicals. In the proposed work spectral properties of materials are used to identify the adulterants using NIR Spectroscopy.  NIR spectroscopy which is primarily used in material science applications is used here to perform analysis of various food adulterants. In the proposed work presence of adulterants like Red lead salt, and Brick powder were found and the quantity of these adulterants were also measured. By this detection process it is possible to avoid using the food stuffs with more quantity of adulterants.
