This study investigates the effect of animal fat replacement by oil mixture emulsion hydrogels on quality characteristics of foal burgers. Three batches were manufactured: control (CON) -100% of pork fat; treatments 1 and 2 (T1 and T2)pork fat was totally replaced using oil mixture emulsions, avocado (T1) or pumpkin seed (T2) mixed with algal oil. These fat replacements were accompanied by a significant decrease in fat content (P < 0.001) and colour parameters (P < 0.05). Any significant differences in texture were observed in reformulated patties, except for gumminess (P < 0.05) and chewiness (P < 0.001). Moreover, a healthier fatty acid profile was reached (P < 0.001), saturated fat decreased, mono-(T1) and polyunsaturated fatty acids (T2) increased and an improvement of all health indices was observed. However, the sensory acceptability of burgers was unaffected (P > 0.05). Thus, these fat reformulations represent a promising strategy to obtain healthier foal burgers with improved nutritional characteristics without affecting sensory properties.
