Non-destructive detection of peanut off-flavors using an electronic nose

An electronic nose was tested to determine if half-kernel, whole kernel, and pod peanuts could be significantly separated based on the presence of off-flavor-indicating volatiles in the kernel. The sampling and data analysis technique used was developed previously and successful at separating ground peanut kernels. Statistically significant differences were detected for all three levels of sample destruction. The electronic nose was able to separate pods at a higher level of significance than the OVM technique and the GC technique for ethanol and ethyl acetate.
