The present study investigates the effects of the partial substitution of the pork back fat with different vegetable oils (sea buckthorn, walnut and sunflower) and walnuts on the chemical composition, texture profile and sensory characteristics of meatloaves. The dry matter and ash content of meatloaf with vegetable oils and walnuts were higher than the control sample (P < 0.05). The cooking loss, energy values and lipid oxidation for the samples with walnuts and vegetable oils were lower than the control sample. The meatloaf sample containing walnuts and sea buckthorn oil had the highest total antioxidant capacity. The partial substitution of pork back fat showed a positive effect on textural and sensorial characteristics. Results reveal that the incorporation of vegetable oils and walnuts has successfully reduced the animal fat content in the finite products while improving the quality characteristics.
