NEWBURY PARK, Calif.–(BUSINESS WIRE)—March 20, 2007–Electronic Sensor Technology, a leading provider of ultra-fast vapor analyzers, announced today that zNose®, an electronic sensor instrument is able to detect aflatoxins in corn.

The recent surge of illness in dogs and cats has been determined by the Departments of Agriculture in both New York and New Jersey to be caused by food contamination.  Dogs and cats became ill after consuming their foods which were contaminated by aflatoxin.  After ingestion, the animals developed aflatoxicosis, a potentially a life-threatening illness.  Aflatoxin is a naturally occurring toxic chemical produced by the growth of fungus on certain food and feeds.

EST’s zNose® electronic sensor instrument is able to capture and analyze nearly any odor, fragrance or chemical vapor within ten seconds, and can detect aflatoxin in corns. Corn silage is the storing and partial fermentation of forage plants such as wheat or corn in the silo. Moisture is responsible for the possible growth of molds and toxic substances produced by fungi and mold, such as aflatoxins (aflatoxicosis) and fusarium moniliform (moldy corn disease); both are potentially fatal if ingested. Molds and fungus produce odors which contain microbial volatile organic compounds (MVOC) which are perceived by humans as musty smells.

The following is a technical paper which describes the use of zNose® for quality assessment of corn silage.

zNose® is actually a very versatile, ultra-fast GC with the ability to perform a full hydrocarbon analysis. This episode demonstrates one of the many zNose®‘s applications.  It is currently being used for environmental, food/beverage, petrochemical, life science and Homeland Security applications.  For more information, please visit our website at www.estcal.com
