PARTIAL REPLACEMENT OF PORK BACK‐FAT BY VEGETABLE OILS IN BURGER PATTIES: EFFECT ON OXIDATIVE STABILITY AND TEXTURE AND COLOR CHANGES DURING COOKING AND CHILLED STORAGE
The present study was aimed to examine the impact of partial back‐fat replacement (50%) by avocado (A), sunflower (S), and olive (O) oil on the chemical composition, oxidative stability, color, and texture of porcine burger patties (10% fat) subjected to oven cooking (170 °C/18 min) and chilling (+...

| Sumario: | The present study was aimed to examine the impact of partial back‐fat replacement (50%) by avocado (A), sunflower (S), and olive (O) oil on the chemical composition, oxidative stability, color, and texture of porcine burger patties (10% fat) subjected to oven cooking (170 °C/18 min) and chilling (+ 4 °C/15 d). The addition of vegetable oils caused a significant reduction of saturated fatty acids and a concomitant enrichment in unsaturated fatty acids. The incorporation of vegetable oils to porcine patties caused a significant reduction of TBARS formed as a result of cooking and the subsequent chilling. The usage of vegetable oils as back‐fat replacers had no impact on the formation of protein carbonyls. Porcine patties with A‐ and O‐patties displayed a more favorable ratio between volatiles contributing to rancidity and those contributing pleasant odor notes. Treated and control patties underwent similar discoloration during processing. The usage of vegetable oils and particularly, avocado and olive oils, as back‐fat replacers, could be an interesting strategy to improve the nutritional and technological properties of porcine patties. |
