Antioxidative polyethylene films for food packaging were experimentally prepared by fortification of TBHQ(tertiary butylhydroquinone) and dl-a-tocopherol at the weight ratio of 0.05, 0.2 and 0.5%, respectively and laminated with nylon. TBHQ and tocopherol contents in the PE/nylon film were analyzed and the antioxidative effects of film were investigated on the lipid oxidation of semi-dried squid during storage at 5℃ and l5℃. TBHQ contents of TAP 1(TBHQ 0.05%), TAP 2(TBHQ 0.2%) and TAP 3(0.5%) were 38, 146 and 365 mg/100g, respectively. Tocopherol contents of DAP l(tocopherol 0.05%), DAP 2(tocopherol 0.2%) and DAP 3(tocopherol 0.5%) were 33, 139 and 356 mg/l00g, respectively. TBA value and POV during storage of semi-drid squid were affected both by storage temperatures and packaging films. Lipid oxidation during storage was retarded by anti-oxidative films, as TBA value of TAP 3 and DAP 3 revealed about 50% of control after storage at 5℃ for 20 days and similer effects in POV were also observed.
