A well-balanced diet is a very important factor to prevent various lifestyle diseases such as obesity, diabetes and hypertension. Meeting nutritional needs is essential for growing children, especially for infants. Therefore it is necessary to develop accurate as well as precise techniques to measure nutrient content. Even though previously established methods are relatively accurate, these are time consuming and cause environmental pollution by using organic solvents and strong acid. In these regards, spectroscopic methods would be great alternatives to official methods for the quantitative analysis. Mid infrared spectroscopy provides qualitative information regarding molecular functional group from fundamental vibrations. Near Infrared Spectroscopy(NIR) uses Overtone and Combination bands associated with the fundamental vibrations seen in the Mid-IR. A fast and eco-friendly method using FT-IR and NIR has been applied to qualitative and quantitative analysis in various fields. In this study, we applied Near Infrared Spectroscopy (NIR) combined with Chemometrics to quantitative analysis of fat, protein and carbohydrates in milk powder.
