Sensory study of flavour compounds in extracts of salted salmon eggs (ikura)

Water soluble extracts were prepared from ikura and each component was analysed. Upon reconstruction of a synthetic ikura extract with pure reagents on the basis of the analytical data, flavour components were sensorily examined by an omission test. This revealed that only 12 components played an important role in producing the characteristic taste of ikura. The novelty of some nucleosides as taste factors is also discussed.
