香りの科学 Can We Selectively Make a Jasmine Fragrance’s Molecular Form?
Enzyme and chemical reactions selectively produced a Jessemal stereoisomer, with a 95% final-step yield but 18% overall yield.
香りの科学 Can Fabric Release a Floral Fragrance Little by Little?
Hydrolysable profragrances increased measured fragrance concentrations above cotton after one and three days, without testing perceived strength or consumer preference.
香りの科学 Can Yeast Produce More of a Key Patchouli Aroma Compound?
Engineering enzymes, pathways, and PDR12 improved patchoulol recovery in yeast. Reported titers came from the dodecane phase, not purified product or total culture content.
香りの科学 Can 13 Compounds Recreate the Aroma of Tahitian Vanilla?
A 13-compound reconstruction resembled Tahitian vanilla across seven attributes rated by 11 panelists, but the test did not establish sensory equivalence.
香りの科学 Can a Green Note Make Vanilla Smell More Like Rum?
A green-smelling compound enhanced vanilla’s rum-like character in expert assessments and changed cultured-cell receptor responses, without proving a direct perceptual mechanism.
香りの科学 Do Natural Fragrance Ingredients Have a Smaller Environmental Footprint?
A life-cycle assessment of 27 fragrance ingredients shows why production processes and assessment methods matter more than origin labels alone.
香りの科学 Can We Identify the Origin of Anethole in Essential Oils?
Composition and carbon isotope measurements helped investigate anethole origins, while hydrogen isotope ranges alone risked misclassifying natural variation.
香りの科学 Does a Higher Price Guarantee Essential Oil Quality?
Analyses of citrus oils bought mainly online found that price and natural claims alone did not establish composition, purity or authenticity.
香りの科学 Can Orange Essential Oil Testing Be Faster and Use Fewer Resources?
A faster chiral GC-MS method retained useful orange-oil information while reducing analysis time, electricity and helium use.
