Some Aspects Of Qualitative Structure-Odor Relationships

Qualitative odor-structure relationships have been applied for more than a century. The results of these studies are mostly the consequence (outcome) of the application of common sense gathered by experience. Two main features characterize the molecular structures of odorant molecules: “electronicity” (electronic charge distribution over a molecule) and “stereocity” (volume, shape and profile of a molecule).

Pattern Recognition Methods for Discrimination of Essential Oils (Rose Oils) by Their Gas Chromatograms

It is possible to distinguish between essential oils of the same type and their mixtures by analysing their gas chromatograms using a pattern recognition method.

Perception of Characteristic Axillary Odors

A significantly high level of anosmia for(E)- and (Z)- 3-methyl-2 -hexenoic acids, which are the key components of human axillary malodor, was found to exist among 90 subjects (45 men and 45 women). A distinct steep increase in anosmia with age was observed for the (E)-acid.

Neural Processing of Body Odor

Understanding the body odor/brain activity relationship and its potential implications on the creation of perfumes and personal hygiene products.

Kinds and intensities of odors

If you have engaged in odor testing sessions, you know how exhausted you feel after half an hour of concentrated effort. Working near the threshold level is very difficult indeed. There can be agonies of indecision. I have always told my observers that it is their first snap impression that counts and is usually right. The chemical senses in our bodies are wonderfully designed and will come out with “I can smell it” or “l can’t smell it” instantaneously.

Effects of Fragrances on Vigilance Performance and Stress

The present project originated in an interest in testing the hypothesis that certain fragrances have an inherent ability to affect peoples’ level of physiological arousal independently of their hedonic properties.
