IntroductionCost is one of the main factors affecting consumer food product preferences. For that reason, low-cost production of alternative products has been of interest to food researchers. Mellorine, as an alternative to ice cream, is a good example of such a product. Mellorine is an ice cream or frozen dessert product in which all or some proportion of the milk fat is substituted with plant-based oil (Clarke, 2004;Keeney, 2012). Usage of vegetable oil instead of milk fat promotes human health, since milk fat contains saturated fatty acid in concentrations of approximately 60%-70% (Nadeem et al., 2009) and 0.25%-0.38% cholesterol (Mathur et al., 1999). The use of vegetable oil in ice cream formulation results in a balanced saturated and unsaturated fatty acid composition in the product and lower cholesterol content (Nadeem et al., 2009). Mellorine is widely consumed throughout the world due to its lower cost, cholesterol content, and saturated fatty acid composition compared to ice cream. However, the low cost of the product is not the only factor affecting consumer preference. In addition to cost, customers also take into consideration the textural and sensorial properties of the product. Therefore, it is important both for the cost and the product's acceptability to provide the desired textural and sensory properties of mellorine by changing ingredients like oil or hydrocolloid type.The fat or oil type in ice cream has a significant effect on the quality of the end products (Dogan and Akgul, 2005;Rossa et al., 2012), since it affects qualities like the creaminess (Koxholt et al., 2001), texture, and mouthfeel (Adapa et. al., 2000;Dogan and Kayacier, 2007). In addition, fat contributes to the stabilization of the air phase as well as fat aggregation levels through surrounding air bubbles, which improves melting resistance (Granger et. al., 2005) and ice recrystallization (Goff, 2002). Therefore, selecting the optimum oil type is an important factor in improving the quality of mellorine. Substitution of palm olein with milk fat at a level of 3% did not negatively affect the compositional properties, overrun value, flavor, or sensory properties of ice cream (Nadeem et al., 2009). Adhikari and Arora (1994) reported that, regarding textural characteristics, sensory scores of ice cream containing vegetable oils were lower than those of the control sample; this might be avoided by using different ingredients in the
