Effect on Volatile Profiles of Rapeseeds by Hot-air Drying

Abstract

Abstract: This study was performed to evaluate the effect on volatile profiles of rapeseeds by hot-air drying. The rapeseeds were dried to final moisture content of 8% (wet basis) with different temperature, after which volatile profiles of rapeseeds were analyzed using HS-SPME/GC–MS method. The results were as follows: more than 85 kinds of substances were identified among the volatile profiles of rapeseeds, which were consisted of aldehydes, hydrocarbons, alcohols, esters, acids, phenols, ketones and ethers, with their relative content decreased successively. Among the volatile profiles, the esters, alcohols, olefin and possible glucosinolate decomposition products showed some disciplines with the change of drying temperature.
