Red Palm Oil (RPO) has a high oxidative stability and contains high levels of natural antioxidants, such as vitamin E and carotenoids. In this study, Vitamin E contents and lipid oxidation of chicken nuggets blended with red palm oil consist of NVRO, NVRO-100 and NVRO-50 were compared against the control chicken fat treatment, each containing 10% fat. Vitamin E contents, thiobarbituric acid (TBA) values and peroxide values (PV) for all samples were measured throughout 4 months of storage at -18°C. All the vitamin E homologues were decreased.α-tocopherol and α-tocotrienol decreased faster meanwhile δ- tocopherol decreased slower than other homologues. Besides that, Vitamin E content in NVRO and NVRO-100 was significantly decreased (p<0.05) from 767.15 to 482.14 μg/g and 842.73 to 672.36 μg/g respectively. TBA and PV values for all samples chicken nuggets increased throughout 3 months of frozen storage but started to decrease thereafter. However, chicken nuggets formulated with NVRO, NVRO-100 and NVRO-50 significantly reduced (p<0.05) TBA and PV values compared with chicken fat treatments. This study showed that frozen storage influence vitamin E stability and the potential of utilization of red palm oils in improving nutritional quality and reducing lipid oxidation of chicken nugget.
