Séverine Dallet, directrice de la cellule olfactive du groupe Coty, explique en quoi la chimie de synthèse a révolutionné la palette des parfumeurs.

Finally, some good news.

Investigating the volatiles isolated from a commercial spirulina (Arthrospira platensis) dietary supplement by gas chromatography–olfactometry (GC–O) in combination with an aroma extract dilution analysis (AEDA) resulted in 29 odor events with flavor dilution (FD) factors between 8 and 2048. Identification experiments, including various offline and online fractionation approaches, led to the structure assignment of 30 odorants, among which the most potent were sweaty 2- and 3-methylbutanoic acid (FD 2048), roasty, earthy, shrimp-like 2-ethyl-3,5-dimethylpyrazine (FD 2048), vinegar-like acetic acid (FD 1024), and floral, violet-like β-ionone (FD 1024). Static headspace dilution analysis revealed sulfuric, cabbage-like methanethiol (FD factor ≥ 32) as an additional potent odorant. In summary, 31 important spirulina odorants were identified in this study, and 14 were reported for the first time as spirulina constituents. Our data will provide a basis for future odor optimization of spirulina-based food products.

Abstract. Attempts to map odor percepts to physical and chemical parameters have a long and challenging history. In contrast to color vision, where three c

In "Human History on Drugs," Sam Kelly explores what the research can tell us about one of history’s most brilliant — and troubled — artists.

How do restaurants from around the world find their way into the Michelin Guide? Here's how inspectors decide which joints receive a star.

Nearly 20% of US packaged foods contain synthetic dyes, raising health concerns, especially in products aimed at children.

Mice taught to link smells with tastes, and later fear, revealed how the amygdala teams up with cortical regions to let the brain draw powerful indirect connections. Disabling this circuit erased the links, hinting that similar pathways in humans could underlie disorders like PTSD and psychosis, and might be tuned with future brain-modulation therapies.

The acidity of drinks like Red Bull can erode dental enamel, but a lab experiment suggests this could be avoided via calcium fortification

Five rare American berries that are worth trying if you find them include kiwi berries, lingonberries, boysenberries, gooseberries, and white raspberries.

We can probably safely assume Rome, in many areas, was likely pretty dirty and rank-smelling. That said, there’s evidence of perfumes, incense and even deodorants.

Honey is a natural sweetener, and bacteria loves to feast on sugar. But honey is remarkably resistant to spoilage. What's behind its ability to beat the bugs?

We know that sleep quality is important for many different aspects of our health, and there are multiple ways to get better shut-eye – including the right bedroom environment, regular exercise, and according to the latest research, lots of fruit and vegetables.

In a Perspective published in PNAS Nexus, Julio M. Ottino describes different classes of creativity and proposes a benchmark for the highest level of creativity. Combinative creativity is the process of combining existing elements to create new solutions, while transformative creativity leads to entirely new frameworks.
