Identification of various retention/release behaviours of odorant molecules in dairy and pectin gels: the role of structural features

2014

Reducing the fat content in food requires a reformulation by adding thickeners that may cause a different perception of aroma. Maintaining an adequate level of acceptability of these reformulated products for consumers requires a better understanding of the mechanisms that control the retention/release balance of odorant molecules in food matrices. [1]. Although pectins are commonly employed as thickeners [2], their effect on the retention of odorant molecules in nonhomogeneous products [3, 4] has been examined more frequently than their effect on the retention of odorant molecules in simple model gels [5]. The purpose of this study was to explore and compare the effects of pectin in differ…
