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.

One of the popular meat products that are in demand among the population of Kazakhstan are sausages. So in the production of sausages, minced meat can contain up to 35% saturated fat. Saturated fats provide the right texture and juiciness, so potential fat substitutes should have good nutritional value and provide the necessary structural and rheological properties. Due to the negative effects of excess consumption of saturated fats and trans fatty acids, there is a need for research into alternative replacements for such fats in meat products. Partial or complete replacement of saturated fats with food oleogels in meat products is the most promising for imparting the desired quality indicators with the content of beneficial unsaturated fatty acids. The purpose of this study was to obtain oleogels based on sunflower and soybean oils and beeswax, as well as further study of their physicochemical, organoleptic characteristics, as well as oxidative stability during storage.The studies were carried out in accordance with the normative and technical documentation. The resulting oleogels can later be used in sausage products to partially replace animal fats and reduce trans-fatty acids.
