NEWBURY PARK, Calif. -- Electronic Sensor Technology, a leading provider of ultra-fast vapor analyzers, announced today that its zNose(R) electronic sensor instrument is able to detect aflatoxins in corn.

A 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 was contaminated by aflatoxin. After ingestion, the animals developed aflatoxiosis, a potentially life-threatening illness. Aflatoxin is a naturally occurring toxic chemical produced by the growth of fungus on certain food and feeds.

EST's zNose(R) electronic sensor instrument is able to capture and analyze nearly any odor, fragrance or chemical vapor within 10 seconds, and can detect aflatoxin in corns. 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.

A technical paper describing the use of zNose(R) for quality assessment of corn silage is online.

The zNose is a versatile instrument based on ultra-fast gas
chromatography with the ability to perform a full hydrocarbon analysis. It simulates an almost unlimited number of specific virtual chemical sensors, and produces olfactory images based upon aroma chemistry. The zNose is able to perform analytical measurements of volatile organic vapors and odors in near real time with part-per-trillion sensitivity.

This episode demonstrates one of the many applications for zNose. It is currently being used for environmental, food/beverage, petro-chemical, life science and Homeland Security applications.

Founded in 1995, Electronic Sensor Technology has developed and patented a chemical vapor analysis process.
