Abstract
Milk is among the food more consumed by humanity. In this way, a study of its physical-chemical characteristics is
justified to analyze if its components are by the legislation and if its hygiene conditions, more precisely the use of
formaldehyde as a preservative, are established. The International Agency for Research on Cancer warns that
formaldehyde has physicochemical properties that make it carcinogenic when consumed in food. In Brazil, the
legislation does not establish minimum values for the presence of formaldehyde in foods of animal origin, and the
technique suggested by the Ministry of Agriculture, Livestock, and Supply is a qualitative test. With the large
consumption of milk by the Brazilian population and because it is a food subject to adulteration. The present work
sought to analyze milk in terms of its physical-chemical characteristics (fat, density, freezing point, non-greasy solids,
lactose, and proteins) and develop a methodology to analyze formaldehyde derivatized with 2,4-dinitrophenylhydrazine
in milk samples using gas chromatography coupled to mass spectrometer.
