The application of intelligent sensor array for air pollution control in the food industry

One of the most signifi cant improvements in the food industry during the next few years is likely to be the development of intelligent sensor array systems that can give useful information not only about the food quality characteristics but also on the environment of the food production. For instance, the sensory array system, often called "electronic nose," would allow the monitoring of off-odors and taints, often present at very low levels, or the odor quality of a food from the raw material to the fi nal product.
