Abstract
Near Infrared Spectroscopy can act as a feasible tool for detecting the presence of detergent as an adulterant in milk. Present work was carried out to formulate a chemometric model to evaluate the existence of detergent as contaminant in milk, qualitatively as well as quantitatively using NIR Spectroscopy. Total 30 samples were prepared using three different varieties of milk, out of which three samples was free from adulterants and rest were having detergent present in them. Those 27 adulterated milk samples were having detergents at nine disparate concentrations: 0.025%, 0.05%, 0.1%, 0.2%, 0.4%, 0.6%, 0.8%, 1.0% and 2.0% of detergent respectively for each kind of milk. The data collected from NIRS instrument was analyzed using chemometric software (CAMO Unscrambler version X 10.3). The Principal Component Analysis (PCA) was run on the sample set to know the relation between the different samples on the basis of the Near Infrared spectral data.
