recently consumers have directed their interest towards reduced or low-fat products as they associated them with a reduced risk of obesity and coronary heart diseases. The consumption of low-fat foods has become a way of life for many health-conscious people. Typically, ice cream contains 10- 16% fat. But, in recent years, the dairy industry has developed a variety of low-fat and fat-free ice cream products. In Turkish Food Codex, three descriptors were introduced for fat content in ice cream, i.e. reduced-fat, regular and whole ice cream. The revision of labelling standards by the Food and Drug Administration has permitted the use of appealing names such as reduced-fat, low-fat and non-fat ice creams for products containing less than 10% milk fat that are targeted at health-conscious consumers. However, quality aspects in many of these products do not meet consumer expectations for ice cream. Compared with traditional ice creams, the low-fat ice creams suffer from low flavour and textural quality. Devereux et al. reported that texture was more important than flavour in determining overall acceptability of the low-fat foods. Removal of fat causes body and textural problems such as coarseness and iciness, crumbly body, shrinkage and flavour defects. Ice cream manufacturers have made a practice to use milk fat replacers in order to form products that meet the demands of health-conscious consumers. Accepted fat substitutes for ice cream are made of carbohydrates and proteins, instead of being based on lipid, which. may form lipophilic particles. Whey protein and inulin are well known fat replacers for reduced-fat foods [. 2 , 8 ]. Fat replacers based on whey protein have distinctive properties that can allow them to perform in food in a manner similar to that of fat globules. Nowadays, separation and other process technologies provide the basis for adding value to milk through the production of proteins that provide the food industry with ingredients to meet specific needs such as improvement in texture [. 9, 10]. Whey protein isolates (WPI) from ion exchange processing, which contain no lactose, are available for blending with other ingredients to provide the non-milk solids (NMS) content and improve the textural properties desired for ice cream formulations [ 2 ]. Recent studies have focused on the effects of other whey protein based fat replacers in ice cream such as
