Emulsion systems: From stability concerns to sensory properties

Abstract

Emulsions need to fulfil many demands and expectations regarding stability, safety and efficacy on the one hand, and sensory properties on the other, in order to be acceptable to consumers. For stability and sensory properties in particular, rheology, textural analysis and sensory evaluation are important. In this chapter, three case studies are presented showing the possible use of these techniques in various fields, as well as possible substitution of one technique with another. Examples show that certain sensory characteristics can be predicted to some extent by instrumental, rheological and textural measurements. A combination of instrumental tools and simplified sensory studies could be used to characterize a consumer-satisfying Alkyl Polyglucoside-based emulsion product in order to achieve adequate results in a shorter time with less expense.
