| Abstract |
Substituted high oleic safflower oil in dairy products as a fat replacer is desirable to meet consumer concerns for dietary healthy food. Ice milk mixes prepared by various substitution levels of high oleic safflower oil of 25%,50%,75% and 100% from milk fat, plus the control which contain 4 % milk fat were investigated. Results indicated that the increase in the replacement level of high oleic safflower oil induced a significant decrease in concentration of saturated fatty acids especially (palmitic acid C16:0) and significant increase of mono - unsaturated fatty acids (oleic acid C18:1). Mean while, there was no significant decrease in specific gravity, weight /gallon Results showed significant decrease in the viscosity values as the proportion of high oleic safflower oil of the prepared ice milk mixes treatments was increased. .
Whereas, pH values did not exert significant effect in ice milk mixes. Overrun values of ice milk from milk fat with safflower oil substitution of 25, 50 and 75% were significantly decreased compared with the 100% safflower oil and control of 100% milk fat. Moreover Ice milk made with substitution level of 25 % high oleic safflower oil had significant increase in melting resistance which gradually decreased with increase of the substituted levels replacement milk fat with 25 and 50% high oleic safflower oil. While replacing milk fat by 25% and 50% high oleic safflower oil significantly decrease peroxide values in fresh and after three menthes in freeze-storage. Meanwhile acid value decreased significantly when compared with the control during freeze- storage for three months. Sensory evaluation showed that ice milk containing 25 % and 50% safflower oil had the highest score and could be satisfactory in fulfilment the requirements of dietary purpose.
