ABSTRACT:
The present invention is drawn to evaluation of the aroma of aroma-emitting substances, such as agricultural grains and oil seeds, in a safe and quantitative way. This is accomplished by causing a known volume of non-toxic gas to pass through the aroma-emitting substance, absorb the aroma, and deliver it to an evaluator. This enables the evaluator to sniff the aroma and thereby make gross quantitative evaluations with respect to the strength of any particular odor of the substance.
