Abstract
Sorption of aroma by three common food packaging plastics in an aqueous system was investigated. All plastics, (LDPE and 2 ionom‐ers), exhibited similar sorption behavior. Equilibrium partition coefficients (Ke), ranged between 2 and 38 for benzaldehyde, citral and ethyl butyrate. A Ke of 3.4 × 103 for limonene indicated a strong affinity for the plastic phases. An equation was derived using Ke to predict the extent of sorption from a given aroma‐plastic system. Sorption isotherms were measured at three temperatures for limonene in a model system. A comparison of limonene sorption alone and from orange oil, showed similar patterns, with a lower Ke for orange oil. Triangle test results indicated that the sorption was detectable to the human senses.This publication has 5 references indexed in Scilit:
