Development of Methodology for Detection of Formaldehyde-DNPH in Milk Manager by Central Composite Rotational Design and GC/MS

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