PLA antioxidant films were placed in contact with 95, 50, and 10% ethanol at 40 and 20°C. Released antioxidants were regularly measured by high-performance liquid chromatography system for 60days. Ascorbyl palmitate was completely degraded during film preparation and is not a suitable antioxidant for PLA antioxidant-active packaging. The diffusion coefficient (D) and partition coefficient (K) of antioxidants were calculated based on obtained data. Diffusion of the antioxidants from PLA to the simulants showed a Fick's behavior with the diffusion coefficient (D) value between 10−9 and 10−11cm2s−1 with 0-100% of release. Faster and higher release of antioxidants occurred at 40°C according to Arrhenius law. At 40°C, TBHQ in 95% ethanol decomposed to 2-tert-butyl-1,4-benzoquinone and other quinone derivatives, and α-tocopherol in 50% ethanol decomposed to some unknown neoformed compounds. Antioxidants molecular weight, Log P, simulant polarity, and temperature were the most influencing factors on antioxidants release rate from PLA films in contact with food simulants. The D and K coefficients of studied antioxidants from PLA in three food simulants and two temperatures can be used to create PLA antioxidant-active packaging to continually control the oxidation reactions in diverse foodstuffs to ensure higher food qualities. The PLA antioxidant-active packaging approach also permits to reduce the amounts of directly added antioxidants in foods to provide safer foods.
