Abstract

A natural antioxidative Monodora myristica (Ehuru) active film package for lipid food preservation was produced by cast method. 0 - 5% w/w ehuru antioxidant extract (EAE) was incorporated into PSF film. Into another PSF resin was incorporated 5% alpha tocopherol (AT) and another, a blend of (EAE)/ α-tocopherol (AT). Tetrahydrofuran (THF) and Nmethylpyrrolidinone (NMP), were used as solution solvent, in ratio 3:1. The radical scavenging abilities of the developed films were analyzed and compared to the pure PSF (control) using 2, 2- diphenyl-1-picrylhydrazyl (DPPH) solution. Finally, the ability of the films to stabilize peanut oil against oxidation were tested by measuring some rancidity analysis of the actively packaged peanut oil. The result showed that the radical scavenging properties of the active films increase with concentration of EAE infused inside the film increased from (0% - 5%), and 5% EAE incorporation created a compact film without any optical noticeable pore. This was confirmed by the permeation rate of oxygen across the film which decreased from (0.1079-0.0277) m3/s as concentration EAE increased. Generally, results showed that natural antioxidant derived from Ehuru seeds (EAE) exhibited the best delay of lipid hydrolyses by exhibiting the shortest oxidation time. It was also deduced that concentration between 2.5 and 5% could comfortably be used to produce the active package because their effect on oxidation of lipid oil are not significantly different from each other 7.85± 1.13 and 7.27± 1.69 respectively. Results obtained from the oxidative analysis confirmed the effectiveness of the active film of natural antioxidant derived from Ehuru seeds (EAE) in slowing down lipid hydrolysis and increasing the oxidative stability of peanut oil, having the smallest PV of 7.35±2.00 and the smallest P-AnV of 18.12± 1.57
