Abstract:

Plastic as food packaging can cause environmental and health problem. One solution for this problems is by substitute conventional plastic into biodegradable plastic such as poly(lactic acid) (PLA). To improve the physical and chemical properties of PLA, synthetic antioxidant such as Butyl Hydroxyl Toluene (BHT) and Tert Butyl Hydroxyl Quinon (TBHQ) were added into PLA. The analysis was carried out on the PLA-BHT and PLA-TBHQ packaging and also food simulants before and after storage at different temperature for 10 days. The analysis included visual appearance, antioxidant activity, total phenol and overall migration. Both PLA-BHT and PLA-TBHQ packaging that were incubated at temperature 40°C had larger migration than at 29°C. The antioxidant activity and total phenol of PLA-TBHQ was higher than PLA-BHT and both of them had decreased antioxidant activity and total phenol during storage but the decreased rate at temperature 40°C was higher than at temperature 29°C.
