title: Production and characterization of a functional Iranian white brined cheese by replacement of dairy fat with vegetable oils.
abstract: Full-fat cheese usually contains high amounts of saturated fatty acids and cholesterol, which may have negative health effects. In this study, full-fat white brined cheese, as a control sample, and experimental cheeses with olive and canola oils (T1, white brined cheese containing 50% canola oil, T2, white brined cheese containing 50% olive oil, T3, white brined cheese containing 100% canola oil and T4, white brined cheese containing 100% olive oil) were prepared from bovine milk. Physicochemical properties, lipolysis, proteolysis patterns and sensorial properties in the prepared samples were determined during 80 days of storage at 20-day intervals. Cheese incorporating vegetable oils showed lower amounts of saturated fatty acids and higher amounts of unsaturated fatty acids compared with the full-fat cheese (control) samples. Moisture, pH, lipolysis value, as assessed by the acid-degree value, and proteolysis values (pH 4.6 SN/TN% and NPN/TN%) significantly (p < 0.05) were increased in all samples, whereas total titrable acidity decreased during 40 days of ripening but then increased slightly. Sensory properties of white brined cheese incorporating with vegetable oils were different from those of full-fat cheese samples. White brined cheese containing olive and canola oils (100% fat substitution) received better sensory scores compared to other samples. The results showed that it is possible to replace dairy fat with olive and canola oils, which can lead to produce a new healthy and functional white brined cheese.
