This study aimed to incorporate the herbal essential oils (Ziziphora tenuior L. (Z. tenuior), Ferulago angulata (F. angulata), and Bunium persicum (B. persicum)) all in three levels (5, 7, and 10% w/w) and tertiary butyl hydroquinone (100, 200, and 300 ppm) to evaluate the oxidation stability of Iranian animal oil (IAO). Z. tenuior, F. angulata, and B. persicum (5, 7, and 10% w/w) and tertiary butyl hydroquinone (100, 200, and 300 ppm) were added to IAO. The physicochemical properties and color analysis, and sensory characteristics (odor, taste, rancidity, and overall acceptability) of the treatments were investigated on days 0, 7, 14, 21, and 28. The results showed that increasing the amounts of Z. tenuior, F. angulata, and B. persicum was associated with reducing acid, peroxide, and thiobarbituric acid values. It also lowered brightness and yellowness while the oxidative stability of the IAO significantly was increasing. It was concluded that the incorporation of B. persicum had the highest effectiveness regarding the proposed criteria with the least effect on sensory properties.
