4.1.1. Heating
PAHs formation in a food takes place on its direct heating at
high temperatures resulting in food combustion. Milk, a dairy product
available at varied fat levels, undergoes different type of processing
like Pasteurization, Skimming etc. Evaluated PAHs in
different heat treated milk samples exhibited following increasing
order: Raw milk < Pasteurized < Ultra High Temperature (UHT)
semi-skimmed milk < UHT whole milk (Naccari et al., 2011).
