Özet

Refined olive oil and partially hydrogenated palm oil (PHPO) blends of varying proportions were subjected to both chemical and enzymatic interesterifications. The rearranged fats were investigated for their melting points, solid fat contents at selected temperatures, fatty acid compositions and trans isomer contents, as well as evaluations, by an expert sensory panel, of their spreadibility and appearance characteristics. The analytical results were compared with those of commercial Turkish margarines. The 30:70 olive oil-PHPO blend after enzymatic interesterifrcation was found to have properties very similar to those of Turkish package margarines, with the additional advantage of possessing higher amounts of monounsaturated fatty acids.
