Technological progress in the production of attractive food packing materials results in the introduction to the market of products containing a large variety of chemical substances. The occurrence of potentially toxic compounds in FCM may cause problems to health of consumers. The problem of the occurrence of primary aromatic amines (PAAs), exhibiting high toxicity to humans. Humans can be exposed PAAs by the usage of a variety of synthetic products which come in contact with food and food products. PAAs are suspected to be carcinogens, so inhalation, skin contact and ingestion are considered the main routes entering human organism. PAAs are mainly originated from synthetic azo dyes widely applied as colorants on plastics and also from the use of adhesives based on polyurethanes.
The main objective of this work was determination of migration level of PAAs from plastic FCM in model solution of 3% acetic acid. Quantitative determination of sum of PAAs, expressed as aniline was made using spectrophotometric method based on diazotization of PAAs and subsequent coupling of the obtained diazonium salts with N-(1-naphthyl) ethylenediamine dihydrochloride. Detection (DL) and quantification limit (QL) was 0,000715 mg/L and 0,002165 mg/L, respectively. Total tested amines for a period of 09.2011 – 06.2013 (in Laboratory testing for health safety of the items for general use in Institute for Public health of Republic of Macedonia) were 1171 items of which 614 were plastic containers, plastic utensils and plastic items that come in direct contact with food.
From tested samples about PAAs expressed as aniline, only 6 sets which coming in contact with food exceed¬ed DL = 0.01 mg/kg. The occurrence of potentially toxic compounds, like PAAs in FCM may cause problems to health of consumers. This is the reason why increased sanitary inspections should be enforced at the market, especially for kitchen utensils that are made in China.
Key words: Food-packing materials, Children toys, Primary aromatic amines (PAAs), Migration, Health safety.
