説明
Organotin compounds, such as di-n-butyl tin and di-n-octyl tin derivatives, are effective stabilizers in the manufacture of rigid PVC containers for food packaging use. Certain derivatives, however, have biological activities in food hygienic sense.<BR>The determination of minute amount of di-alkyl tin compounds migrated from container into food-simulating media was successfully carried out by dithizone-extraction and succeeding colorimetric measurement in 1, 2-dichloroethane. Inhibition of heavy metals was eliminated by EDTA-extraction in borate buffer of pH 8.4.<BR>Rigid PVC containers, including different types and concentrations of di-n-alkyl tin stabilizers were prepared, in which Various food-simulated solutions were packed and stored at a temperature of 50°C. The stabilizer migrated from PVC into the solution was determined after aging.<BR>The extent of migration was larger in hydrophobic solution than in hydrophillic media. The extraction of di-n-butyl tin increases with increase of the content formulated in PVC, while di-n-octyl tin was scarcely extracted. Effect of other additives on the migration was observed for di-n-octyl tin-stabilized system in fat-simulated medium.
