The study found that using monoglyceride-based oleogels as a fat substitute in Bologna sausages can make the sausages lighter and slightly increase hardness, as well as improve sliceability. Consumers showed good acceptance of the products, indicating potential for oleogels as fat replacers in meat products.
Bologna sausages were produced with 25, 50, 75 and 100% of their pork fat content replaced by monoglyceride based-oleogels prepared from conventional or high oleic sunflower oils. Physicochemical, technological, and sensory properties of Bologna sausages were evaluated. Emulsion stability was little affected by fat replacement. All treatments batters exhibited characteristic rheological properties of gels (G' > G ''). Overall, the addition of oleogel as a fat substitute made the sausages lighter and a small increase in hardness was observed in the sausages with total fat replacement by oleogels. The sliceability was affected by the reformulation and a higher number of slices were obtained in samples with oleogels in relation to the control. These results were associated to the product structure that became more compact as the amount of pork fat was reduced. However, all samples showed good acceptance by the consumers and no significant difference was observed between treatments. The results showed that monostearate-based oleogel can be a potential fat replacer with higher amount of unsaturated fatty acids to be used in meat products, but retaining the desired characteristics of the traditional products.
