Chemically interesterified blends (CIB) and non-interesterified blends (NIB) of corn and palm oils (75%w/25%w) were studied in the production of Turkish White cheese (TWC) to modify the fatty acid composition of traditional product. Milk fat (3%) was replaced by CIB and NIB for 25%, 50%, 75% and 100%. All cheese groups were ripened at 5 degrees C for 90 days. Samples were taken from each group after 3, 30, 60 and 90 days and analysed for their basic composition, lipolysis and proteolysis. CIB-incorporated cheeses showed a higher degree of lipolysis than the control sample and the NIB-incorporated counterparts. Fatty acid composition and sensory properties of the final product showed that the incorporation of CIB and NIB in TWC improved the nutritional content of the product because it altered the fatty acid composition without any adverse effect on sensorial quality. We concluded that in production of TWC, 50% of milk fat could be successfully replaced with CIB and NIB, preferably CIB, because of its superior sensory quality.
