Abstract

Flavors are combinations of many subjective (sensory) properties, each of which depends in a complex way on the objective compositional characteristics of a product. A systematic approach to the design, control, and modification of flavor requires uncovering the functions that relate the various sensory properties to the analytical parameters, including the composition of headspace vapors. Available low-cost computerized programs are easily and routinely applicable to the search for such complex subjective/objective correlations. Allowances must be made in the data treatment for nonlinear correlations and interactions between the parameters. This approach is illustrated by a study of beer flavor.
