    Abstract

    The oral residence time of low-viscosity emulsions, like milk, is relatively short. Despite this short residence time, people can easily perceive differences between these emulsions. Our research is dedicated to unravel the oral behaviour of emulsions in relation to sensory perception. The aim of this study is to thoroughly evaluate the sensory perception of low-viscosity emulsions in relation to a range of emulsion engineering control parameters. A standard, 10% sunflower containing emulsion stabilised by whey protein isolate was modified with respect to fat type (sunflower oil, palm fat and milk fat), fat content (0¿40%), droplet size and addition of guar gum or particles. Fat-related attributes, like creaminess, fattiness, satiation and coating after feel were affected by fat type, fat content and guar gum addition. Increasing fat content and/or replacing sunflower oil by solid fat, which melts around body temperature, were the most effective ways to increase fat and creamy perception of low-viscosity emulsions. Control of emulsion perception by varying droplet size in the range from 0.5 to 6 ¿m did not affect fat-related attributes.
