Electronic Nose Inspects Cheese, Hints At Human Sens...( ity of products ranging from ...),Health

ity of products ranging from foods to petrochemicals. Since then, few companies have embraced the expensive technology -- costs run as high as $100,000 per machine. That's why Harper and Kuen-Da Jou, a graduate student, decided to find out whether the devices really work.

Compared to the senses of sight, hearing, and touch, scientists know relatively little about how humans smell and taste. Designers of electronic noses have tried to mimic human noses by linking together sensors that detect a variety of volatile compounds.

"We wanted to prove whether the technology was real -- whether we could differentiate between aromas and relate those differences back to the way humans discern smell. That was essential as a first step to determining whether these devices would be useful in industry and research," said Harper.

The results appeared in a recent issue of the journal Milk Science International. Harper discussed the work last month at the 216th national meeting of the American Chemical Society in Boston. Harper and Jou compared the opinions of a human sensory panel to the scent analysis of a commercially-available electronic nose. The panel rated five different types of Swiss cheeses according to scent and flavor.

After the panel finished its work, Harper and Jou studied the cheese samples with
