Abstract
This study prepared six different ice creams to investigate the effect of yeast protein (YP) on their sensory, rheological, thermal properties and fat destabilisation. Results indicated that YP could improve sensory quality, flow and viscoelastic properties. The thermal property was also positively influenced by YP with a significant decrease in frozen water percentage and an increase in glass transition temperature (P < 0.05). Additionally, the particle size and confocal laser scanning microscopy results illustrated that YP could moderately promote the fat aggregate percentage and size. Overall, YP could serve as a fat replacer to produce reduced‐fat ice cream.
期刊介绍：
The International Journal of Dairy Technology ranks highly among the leading dairy journals published worldwide, and is the flagship of the Society. As indicated in its title, the journal is international in scope.
Published quarterly, International Journal of Dairy Technology contains original papers and review articles covering topics that are at the interface between fundamental dairy research and the practical technological challenges facing the modern dairy industry worldwide. Topics addressed span the full range of dairy technologies, the production of diverse dairy products across the world and the development of dairy ingredients for food applications.
