The present study investigates the effects of avocado, sunflower and olive oils used as back-fat replacers, on
the fatty acid composition, oxidative stability, volatiles profile and color and texture properties of cooked pork
patties. The vegetable oils modified the fatty acid profiles of the patties by lowering the percentages of SFA
(from 36.96% to ~25.30%) and reducing the atherogenic index (from 0.41 to ~0.24). Vegetable oils had higher
amounts of antioxidant compounds such as tocopherols (10.8–53.9 mg/100 g) than back-fat (5.9 mg/100 g).
Consistently, patties manufactured with the oils had significantly lower amounts of lipid and protein
oxidation products than control patties. Avocado oil contributed with specific aroma-active terpenes to
patties and had a significant impact on particular color and texture parameters. The results from this study
highlight the technological applications of the vegetable oils as food ingredients in the design of healthier
meat commodities.
