The function of packaging is to protect food from contamination that can disrupt, harm and endanger human health. Packaging material could contain dagerous substances such as lead, that could migrate into the food, and consumed by human. Migration test is intended to ensure food safety by controlling the migration rate of unwanted compounds from the packaging into the food.

The purposes of the study were to determine lead metal content migrated from packaging made of waste paper into fried foods and to define the model of migrating reaction and and the rate of release. The method of the study were kinetics reaction method using Arrhenius equation and lead analysis method using Atomic Absorption Spectrophotometer.

The results showed that there was a number of metallic lead migrated from simulation packaging paper into the simulation fried foods. Increasing temperature and storage time, correspond to the lead levels leached from the packaging increased and showed a linear relationship between storage time and the release. The realising rate of lead agree with first order of kinetics reaction, the plot of the number of lead released toward time produced a straight-line. The constant (K) of lead releasing rate in average was 4.97 x 10-3 ppm / min with an activation energy (Ea) of 3775.3 cal mol-1K-1.

Keywords: lead, used paper packaging, fried foods
