Abstract

The functional and sensory properties of eggs from native laying hens fed the diets incorporated with sardine oil and tomato powder were investigated. Native laying hens (n=120; 28 weeks old) received four dietary treatments, control (sardine oil 0% + tomato powder 0%), T1 (sardine oil 2.5% + tomato powder 0%), T2 (sardine oil 2.5% + tomato powder 0.5%), and T3 (sardine oil 2.5% + tomato powder 1%). Each treatment comprised six replications and employed five birds each. The experimental design used was a 3×3×2 Completely Randomized Factorial Design with the first factor was dietary treatment, the second factor was storage time, and the third factor was storage temperature. Functional and sensory properties data were analyzed by multivariate ANOVA and one-way ANOVA, respectively, and Duncan’s Multiple Range Test was applied to separate the significant values between treatments. Dietary treatment, storage time, and storage temperature showed a significant interaction with the foaming ability (P<0.05). The dietary treatment alone did not give any significant effect on foaming ability. The result also showed a sole significant effect of storage temperature on the foam stability (P<0.05). The combination of tomato powder in the sardine oil-supplemented diet improved the color, odor, taste, and texture of fried egg yolk (P<0.05). Dietary sardine oil of up to 2.5% and tomato powder of up to 1% acted synergistically in improving sensory properties without decreasing the functional properties of eggs. Tomato powder could be used in feed formulation containing sardine oil to give beneficial effects on the functional and sensory properties of eggs produced by native laying hens.
