According to the experimental study of Baryłko-Pikielna,
Martin, and Mela (1994), perception of taste (sourness,
sweetness and saltiness) in O/W and W/O emulsions
by the same oil volume fraction (/ = 0.5) was very similar.
Above examples of studies concerning the release and
perception of volatile and non-volatile compounds from
emulsions show the complexity of this phenomenon, and its dependence on many various factors. It explains some
controversies obtained regarding results and drawn
conclusions.
Among natural flavouring additives, smoke flavourings
(SF) are quite widely used for aromatization of various
products, including emulsion-type ones (as mayonnaises
and salad dressings). In the available literature there are
no studies concerning the release and perception of smoke
flavouring from food or model emulsion matrices. In this
study SF was chosen as a flavouring for its complexity,
reactivity of its components and their distinctive sensory
quality. The detailed chemical and sensory characteristics
of SF derived from the same raw material has been an
objective of separate publication (Kostyra & Baryłko-Pikielna,
2006).
An objective of this study was systematic investigation
of the interaction between model mayonnaise-type emulsion
as a matrix and SF as a flavouring agent and its sensory
effects, including temporal aspects.
