The human nose has hundreds of receptors, each implicit by distinctive DNA to identify different odors. So it justifies the fact that why different people have different sensitivity and reactions to smell. Scientists also suggest that the sense of smell is closely associated with the formation of memories. Reactions to odors can be especially individual. A smell may be pleasant to one person and unpleasant to someone else. This can make the objective measurement of odor difficult to achieve. Odor testing gives the impressions as it is inexplicable. In the past engineers and operators have relied on “odor experts” to interpret odor testing results. Today, odors are very familiar, known to and understandable subjects for all. This chapter discusses the fundamental of odor, odor classification, and odor analysis techniques.
