The effect of temperature levels on antioxidant activity in chicken eggs

Generally, egg heating aims to inhibit microbial contamination, especially on the surface of eggshells and liquid egg products. The application of heating temperature to eggs was carried out at temperatures below 100oC. However, the heating temperature can have an impact on antioxidant activity and the characteristics of egg protein consumption. The treatment uses 3 temperature levels i.e., 45oC, 55oC, and 65oC, respectively. Each treatment was repeated 5 times, a total of 15 units. Each sample was heated for 3 minutes. Parameters were antioxidant activity, total protein, and dissolved protein. The results showed that the different heating temperatures had a significant effect (P<0.01) on antioxidant activity, total protein, and dissolved protein. Value of antioxidant activity and total protein decreased with the increasing of heating temperature. However, increasing the heating temperature can increase the dissolved protein value of chicken eggs. The heating temperature of 45oC on chicken eggs can optimize the antioxidant activity, total protein, and dissolved protein value.
