Studies were carried out on the solubility and permeability of limonene vapor in two cereal package liners. The effect of limonene partial pressure on the permeation rate and permeability coefficient was determined over a concentration range of 0.3 to 7 ppm (wt/v). The equilibrium sorption concentration and solubility coefficient of limonene in the liner films were also determined by a micro-balance gravimetric technique. Data obtained provided information necessary for the estimation of the storage quality of a packaged fruit-flavored cereal product whose quality is related to the retention of volatile aroma constituents within the package headspace.
