By use of extracts prepared by liquid-liquid separation of the volatiles from self-prepared juices of pineapple fruits (Ananas comosus) (n = 14) as well as commercial pineapple recovery aromas/water phases (n = 3), on-line capillary gas chromatography-isotope...

Chem. Senses 37(3) , 229-40, (2012)

Chemoreception is a principle modality by which organisms gain information from their environment, and extensive variation in odor-mediated behavior has been documented within and among species. To examine the mechanisms by which sensory systems mediate these...
