Abstract: The purpose of this research was to investigate the feasibility of using egg white-xanthan gum (EW-XG) complex as a fat substitute to reduce the fat content in high-fat ice cream and thus obtain low-fat ice cream. The effect of lipid replacement in ice cream was analyzed on its physicochemical properties, sensory evaluation and microstructure. The results showed that overrun was increased from 54.9% to 72.6% and melting rate was decreased from 48.32% to 24.3% when 15% fat substitute was added. Besides, the amount of bubbles and fat aggregation were increased. However, the taste and acceptance were reduced when 25%–30% fat substitute was added. Therefore, ice cream was best accepted with addition of 15% fat substitute.

Key words: high-fat ice cream, fat substitute, overrun, microstructure
