In recent years, double emulsions are stated to have a promising potential in low-fat food production, however, there are very few studies on their possible applications in meat matrices. We aimed to investigate the quality of beef emulsion systems in which beef fat was totally replaced by double emulsions (W-1/O/W-2) prepared with olive oil and sodium caseinate (SC) by two-step emulsification procedure. Incorporation of W-1/O/W-2 emulsion resulted in reduced lipid, increased protein content, and modified fatty acid composition. W-1/W/W-2 emulsion treatments had lower jelly and fat separation, higher water-holding capacity and higher emulsion stability than control samples with beef fat. Increased concentrations of W-1/O/W-2 emulsions resulted in significant changes in texture parameters. TBA values were lower in W-1/O/W-2 emulsion treatments than control treatment after 60 days of storage. In conclusion, our study confirms that double emulsions had promising impacts on modifying fatty acid composition and developing both technologically and oxidatively stable beef emulsion systems.
