Abstract

Processing of foods is essential to supply safe and nutritious foods to the growing world population. Considering the foodprocessing conditions and the composition of food products, neo-formed contaminants, such as acrylamide, furan, furfural, 5-hydroxymethylfurfural, nitrosamines, heterocyclic amines, and so on, are known to be formed in highly consumed foods. NOVA classifies foods into four groups as unprocessed/ minimally processed foods, processed culinary ingredients, processed, and ultraprocessed foods. This review aims to stress how the NOVA food-classification system is ambiguous in terms of food safety because thermal-process contaminants might also occur in minimally processed foods or might be prevented in so-called ultraprocessed foods by using industrial food processes or processing aids.
