Brief History of Fragrances
• <1850: only the wealthiest could afford fragrances and perfumes
• <1900: Perfumes were made of entirely natural materials
• 2019: over 3000 fragrance ingredients are available to consumers (>90% chemically synthesized)
• Expected in everything from household cleaners to shampoo to processed food and more!

Brief History of Fragrances
• Use of fragranced materials dates back thousands of years
• “Perfume” comes from Latin per fume meaning “through smoke” as in the burning of incense
• Egyptians pressed, boiled, dried, powdered, macerated in fat, and even distilled
• The early Crusades spread perfumes to Middle Age Europe
• Alchemy turned into chemistry in the 19th century, and fragrance was at the forefront
• 1882: Paul Parquet created Fougere Royale from synthetic coumarin, oakmoss, geranium, and bergamont

Brief History of Fragrances
• Traditional discovery and development of new synthetic chemicals were based on the analysis of natural sources:• Plants (lavender, jasmine)• Fruits (lemon, orange)• Animal (musk, ambergris)
• Three main methods for acquiring

Why study smell?It’s a primal sense
Can we study smell?It’s difficult to understand, but ithas tangible pieces(molecules &receptors)
What questionsshould be asked?
How do we smell?How does the brain learnand interpret these signals?
• 1300 odor receptors in a mouse• 500 in a human
• C. elegans have 302 neurons of which 16
are dedicated to odorrepresenting a 1000
odorant receptorgenes
Gene coding isclearly important
for odorrecognition

Multivariate statistical analysis of a large odorants database aimed at revealing similarities and links
between odorants and odors
• Break up odors into “subjective” categories• 150 odor notes• 1000-2000 odorants
• Use self-organizing maps (SOMs) to relate odor with structure via Artificial Neural Network (ANN)
• Draw 3777 odorants from Flavor-Base (a large library of compounds)
• Retain 3571 after removing compounds activating retronasal stimuli
• Remove any descriptors with <5 related compounds• Kept ones like “fruity,” “floral”• Removed 63 odorants
• Used AI to split odorants into similarity “trees”; cut trees at 3 dimensions deep

Application of natural deep eutectic solvents for the “green” extraction of vanillin from vanilla pods
• 2000 to 3000 tons vanilla produced every year
• <1% of vanillin in the flavor market is from vanilla
• Most extracted with aqueous ethanol (50% v/v)• Leaves potentially undesirable ethanol (up to 35% v/v)• Only non-toxic option
• Natural deep eutectic solvents (NADES) might be an option
• Ionic liquids could be useful, but they are highly toxic
• Some natural liquid mixtures have been shown to be ionic• Organic acids/bases• Could explain biological phenomena
• Unlike lipids or water, can dissolve taxol, rutin, etc.

Identification of key aroma compounds in raw and roasted lily bulbs (Bai He)
• Lily bulbs (‘Bai He’) are a popular ingredient in Chinese cooking
• Little is known about the odorants responsible for their distinct aroma
• Solvation followed by gas chromatography-olfactometry (GC/O) were used to identify new aroma-active compounds

Identification of key aroma compounds in raw and roasted lily bulbs (Bai He)
• They dilute each identified compound and rate how dilute they can still smell it; this gives a flavor dilution (FD) factor• Dilute 1:1 , 1:2, …, 1:1024
• Raw: 25 odorants detected in the FD range from 1 to 1024• Roasted: 42 odorants detected in the FD range from 1 to 1024
Odorants with FD > 63 in Raw Lily Bulbs

Comparison of the aromatic profile of traditional and modern types of Huang Jiu (Chinese rice wine) by
aroma extract dilution analysis and chemical analysis
• “Pure” microorganism fermentation changes aroma profile
• Huang Jiu is a good study• 60% is from traditional techniques
• Open pottery jars• 30 to 90 days• 3 years of aging
• 40% is from modern techniques • Fermentation tanks• 20 to 30 days• 1 year of aging
• Tested with GC-O and GC-MS
