Abstract

Milk provides essential nutrients (carbohydrate, fat, protein, minerals and vitamins) of great nutritional relevance for humans, particularly during childhood. Nowadays, the occurrence of milk adulteration is a major issue in the dairy industry, and has been causing concerns among costumers and food manufacturers. In this context, the objective of this study was developed a simple, fast and non-expensive method to identify and quantify milk adulteration. In this study, three different methods were proposed based on digital image, infrared spectroscopy (IR) and time domain nuclear magnetic resonance (TD-NMR).
