Objectives of the Course
The main objective of the course is to supply information to the food engineering students about the contamination ways of the toxins to the living organisms by food consumption which is the one enterance way of toxins into the body. For this purpose, the toxicological evaluations performed and the general principles applied in the world and in our country for regulating the presence of several toxicants in foods is described. Information is given about the naturally occuring toxicants, the contaminants that have toxic effects when present in small amounts in foods, and the functions of food additives as well as their toxicological aspects when used improperly
