Abstract

In this study , 25% and 50% of milk solids not fat in ice milk mix­es (11%) were partly substitited by sweet whey, acid whey sweet but­termilk and fresh skirnmilk. Results indicated that subtitution with sweet buttermilk en­hanced the physical and chemical properties, and improved the organo­leptic quality of ice milk with a manner better than both fresh skimmilk or whey. It could be recommonded that, promising substitution could be carried out up to 50% with sweet buttermilk or fresh skimmilk and up to 25% with sweet or acid whey in making ice milk.
