The course provides a comprehensive summary of information concerning chemical food safety, with an emphasis on current problems. Attention is paid to hazardous food components that originate during food processing from common precursors, food additives and contaminants of various origins, i.e. from the environment, agricultural practices or from food contacts materials. For each group of contaminants, physico-chemical and toxicological aspects are discussed, attention is focused on the possibilities of consumers´ protection and on minimisation of dietary exposure to these pollutants.

Students will be able to:

• assess chemical food safety.

• design procedures to eliminate the possibility of undesirable substances in food during food processing and storage.

• design ways to reduce exposure of human population to xenobiotics from the diet.
