The effects of incorporating oleogel on properties of model system emulsions

This study aimed to emphasize the utilization of oleogel containing chitosan and pomegranate seed oil as a replacer for beef fat in model system meat emulsions (MEs). For this purpose, beef fat was replaced with oleogel at levels of 0% (C), 50% (OG50), 75% (OG75), and 100% (OG100). The chemical composition, technological quality, microstructure, and oxidative changes of the MEs were investigated. The incorporation of oleogel in MEs effectively reduced saturated fatty acids and cholesterol levels while showing significant increases in polyunsaturated fatty acids. Additionally, the re-formulation process exhibited promising outcomes in enhancing n-3 content. On the other hand, replacing beef fat with more than 50% oleogel led to a decrease in the emulsion stabilities of the MEs. Despite causing changes in color and texture, the inclusion of oleogel proved effective in enhancing oxidative stability. The highest 2-thiobarbituric acid re-active substances (TBAR) value was found in control treatment throughout storage. Furthermore, scanned electron mi-croscope images of the products exhibited a more organized structure in reformulated samples. The comprehensive findings indicate that integrating oleogels into ME formulations can effectively contribute to achieving a healthier lipid profile, along with favorable textural, nutritional, and oxidative qualities.
