This document outlines a chemistry investigatory project on studying common food adulterants in various products like oils, fats, butter, sugar, turmeric powder, chili powder, and pepper. It describes 3 experiments conducted to detect adulterants - testing for dyes in fats, argemone oil in edible oils, and insoluble substances in sugar. Observations showed adulterants like pink coloration in fats and insoluble impurities not dissolving in sugar tests. The conclusion emphasizes the importance of selecting non-adulterated foods for health and avoiding unhygienic food sources.
