Detection of flavour release from pectin gels using electronic noses

An electronic nose device developed in our laboratory was used to follow the flavour release of a multi-component essence encapsulated in pectin gels. Gelation kinetics of high-methoxylated pectin was followed by dynamic rheological measurements in presence and absence of flavour. A transition from...
