A new technique for analysing the headspace volatiles of ripening pears has been developed and when supplemented with olfactory-GLC analysis, allows fairly precise knowledge of flavour impact compounds. It is solid phase micro-extraction (SPME) combined with capillary column GLC/MS. Its advantages and disadvantages are discussed with respect to other purge and trap methods. It is simple to use, inexpensive, durable, self-cleaning and avoids external contamination. However, exposure times and temperatures need to be carefully controlled and low boilers/high boilers may have to be analysed separately.
