Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.

History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract

Simultaneous chemical and sensory analysis with multidimensional gas chromatography-mass spectrometry- olfactometry (mdGC-MS-O) combine classic chromatographic separations with sensory analyses. Trained panelist and human nose is used as a detector simultaneously recording olfactory responses (aromagrams) with chemical separations (chromatograms). Analysis of chromatograms and aromagrams enables separation of odor- (or aroma-) causing compounds in very complex matrixes. Multidimensional chromatography by heart-cutting with Dean’s switch enhances chromatographic separations. Combined with the sensory analyses, it allows for isolation and ultimately, identification of odor-causing compounds. Mass spectrometry detection allows for identification and quantification of specific target compounds. The objective of this paper is an introductory overview of simultaneous chemical and sensory analyses using multidimensional GC-MS-Olfactometry.
