The expansion of the assortment of low-saturated-fat sausages is a trend in healthy eating, and the use of alternative ways to reduce their saturated fat content is required. This study aimed to partially substitute pork fat with 7% and 10% oleogel, obtained by structuring sunflower oil with a two-component mixture of monoglyceride and beeswax, in the recipe for semi-smoked sausage. The physicochemical characteristics of the sausages were evaluated, and the fatty acid profile and sensory properties were analyzed. In the samples where pork fat was partially replaced with oleogel at 7% and 10%, there was a decrease in the content of saturated fatty acids (SFA) by 35% and 38%, respectively. The addition of oleogel to sausages significantly reduced the content of stearic and palmitic acid, increased the content of linoleic acid, and improved the fatty acid profile. The microstructure of the sausages showed a more homogeneous structure with a lower content of large lipid granules as the amount of oleogel added increased. The sensory analysis showed that the addition of 7% oleogel did not deteriorate the organoleptic properties. Therefore, the partial substitution of pork fat with 7% oleogel can be recommended to produce healthy sausages with improved fatty acid profile and sensory properties.
