On Sweetness and Flowers

"French scientists identified a gene that's far more active in a heavily scented kind of rose than in a type with little odor. This gene, which produces an enzyme, revealed the odor-producing process."

AKA "Biosynthesis of monoterpene scent compounds in roses"

Roses have not been designed over centuries of human endeavor to smell good, but to look good. Roses may have been initially valued for their heavenly scent, but over time, they have been selected for reasons of visual beauty.

A selection from Hidden Scents:

Crossing as often as it does with the Food Industry, Fragrance is often interpreted to the mind as taste. “Sweet” is frequently used as an olfactory descriptor. However, calling caramel-smell Sweet is not a chemical consequence of the molecule, but an effect of memory. If sucrose is paired with an odor, any odor, it will eventually “smell sweet”. The potential effect on odor perception that is cued by such multi-sensory information is thought to be the minimization of “perceptual dissonance between the dominant sense (vision) and the minor sense” (Wilson & Stevenson 2006).

Smells are not just Sweet; Castoreum is Umami, and Body Odor, Sour. Yet something about the word, the taste, and the smell of “Sweet” is linked together, and can be evidenced in the fact that the word “sweet” is the most commonly used sub-category heading in the Aldrich catalog (2013), which is a chemical clearinghouse for Flavor and Fragrance scientists. The biases and idiosyncrasies inherent in the Aldrich Catalog as a universal aroma reference are immediate and comprehensive. The catalog is a flavor tool, first of all, and as a commercially-driven pursuit flavor reigns supreme over fragrance alone. The fact that “Sweet” as a sub-category has the most centrality (it falls under Balsamic, Woody, Fruity and Minty) could relate to a confluence of the pervasive availability of sweet aromas, or the sweet-tooth of a certain society, or that there really is something sensually similar about the relative phenomena. Unresolved in that matter, we can scrape-together at least that the description of a smell will tend to be communicated via other, more intentionally-simulable channels of association – anything but the olfactory-specific semantic network of experience, because of course, such a thing is so halting and reluctant in its cooperation, if at all.

In parallel to this gustatory congruency of Sweetness, it is a curious thing to consider: are Florals such an extensive part of the perfumer’s repertoire because of their associated visual aesthetic beauty? David Howes responds in telling of his work with the Papa New Guinean Kwoma people (Howes 2002:76). He presents plastic cards impregnated with scent, and painted with a corresponding color (cinnamon is brown, coconut is white, etc.). When surveyed on the most-liked odor, respondents voted Rose in the vast majority. After having hidden the red-colored Rose scent in an envelope, however, the overwhelming preference disappeared (along with Howes’ search for a universal aroma preference, à la Berlin and Kay, 1969).
