Abstract- One of the most common methods to observe the presence of unknown compounds in materials and solutions is FTIR Spectroscopy. In this paper, different concentrations of Amoxicillin solution were added to intact milk, and samples were analyzed using FTIR Spectroscopy. IR spectrum can show some absorption peaks, an indication absorption of passing light through the mixture of milk and Amoxicillin molecules. Between 1700 cm-1 to 1800cm-1 spectral region, there is a strong absorption peak, being stronger by increasing the amoxicillin concentration. Applying statistics operation as linear regression and calculate R-square, it revealed that there is a linear relation between concentration and absorption according to beer-lambert law. The R-square factor is about 0.96 with very low RSS (near 0.001).This experiment can be a validation of using the FTIR spectroscopy to detect amoxicillin dopant in milk, which is very useful and applicable in the global and national dairy and food industries.
