Oxidative stability of red palm oils blended chicken nuggets during frozen storage

Abstract

The effects of red palm oils known as Naturally Vitamin Rich Oil (NVRO) on the lipid stability of chicken nuggets were determined. Lipid oxidation was analyzed during frozen storage (-18 °C) for up to 4 months. Thiobarbituric acid (TBA) values and peroxide value (PV) for all samples chicken nuggets increased throughout 3 months of frozen storage and then start to decrease thereafter. Chicken nuggets formulated with NVRO, NVRO-100 and NVRO-50 showed lower TBA values and PV compared to the samples prepared with chicken fat. However, among NVRO, there were not significantly different for most of the months. It was concluded that the utilization of red palm oils in chicken nuggets significantly reduced the oxidation of lipid, which was indicated by the PV throughout 4 months of frozen storage.
