| Abstract:
A new technique, solid phase micro-extraction (SPME), has been combined with 60m capillary column GLC/MS to identify and quantify headspace volatiles of ripening pears. Supplementing this powerful identification with olfactory-GLC enables fairly precise knowledge of flavor-impact substances. Advantages and possible disadvantages of this technique will be discussed in comparison to other purge and trap methods. Among the major advantages of SPME are simplicity of use, inexpensive, durable, self-cleaning, and avoids external contamination. Disadvantages are exposure times and temperatures need to be carefully controlled, low boilers/high boilers may have to be analyzed separately. | |
