Fragrant Roots and Neroli Macaroons

essential oil macaroonsThe British Society of Perfumers Annual One Day Symposium was held at Whittlebury Hall in Towcester again this May and had an accidental theme of fragrant roots – with two of the presentations focusing on a different kind of scented root accord unbeknownst to one another. One of the suppliers, Albert Vieille, also went beyond scent and served us delicious macaroons flavoured with essential oils of neroli, rose and mandarin which were perfectly accompanied by the Arabica Coffee Salvador alcoholic extract we smelled alongside them.

There is a perceived danger to hosting any kind of raw material-focused conference on a World Perfumery Congress year because suppliers will inevitably want to save their new launches for that (who wouldn’t?), but this did not cause any difficulties for the BSP ODS as every session managed to find ways to showcase existing materials, new production methods, or to introduce new variants to the UK market. One of the best things about going to these is the group smelling – sitting at a table (or walking around interactive demo sessions) with seasoned perfumers and sharing observations is like gold dust; you learn so much and find all kinds of inspiration and insight.

Wolfgang from BASF showed us a very well-known material, DL-menthol, which he nevertheless felt was unfairly neglected in perfume creations, and called it “the under-estimated baby of the industry.” His quips and style had the room guffawing away and every time I hear him give a presentation I feel a little bit wistful that he didn’t become a chemistry teacher because he would have inspired generations. On the other hand, I’m glad he didn’t because now I get to listen to his presentations at BSP events instead. We also smelled dihydrorosan in demo formulas – it really boosted fruity notes in unexpected ways.

Symrise took us through an interactive presentation where tables were laden with demo formulas showing off Jacinthaflor – an interesting white floral-type material which can bring indolic aspects to fragrances without the discolouration issues, Nerolione – as the name suggests, a high-impact ingredient for orange blossom creations and Irisnitrile – a diffusive iris note booster. I have come to accept that I adore iris scents of all kinds (am yet to encounter one that I don’t love) and the accords we experienced here had interesting cucumber and fresh facets and bloom which can sometimes lack from iris-type notes. It seems clever use of Irisnitrile can really add extra dimension to these accords.

If you think you know what cedarwood should smell like, I wish I could send you some of the Firmenich cedarwood oil Alaska through the screen because it took many of us by surprise – a sparkling grapefruit top with lots of smoky and aromatic nuances and no ‘pencil shavings’ feel. I’d love to create a masculine scent just around this material and expand every aspect. We were also shown Pepper Sichuan supercritical fluid extraction, Lilyflore, Ambrox Super and a Honey Signature base which is a blend of natural materials and synthetic captives. The honey note was so realistic that some visitors were overheard asking for a slice of toast to go with it.

And, to the next fragrant root – vetiver. Emerald Kalama Chemical showed us Azuril, Osyrol and Vetimoss (there is a clue in the molecule names to which one went into the vetiver accord) and we smelled demo formulas including blackwood and fantasy citrus. Vetiver is another one of my absolute favourite smells and I’d love to get a chance to experiment with vetimoss – there were many nuances besides straight-up vetiver that came out at me from the demo.

Pierre rolling out the red carpet

I caught Pierre personally rolling out the red carpet for the winner just before the gala dinner

If any of you follow Pierre the Perfumer on Twitter, you won’t be surprised to hear that he would be up to mischief at an entirely serious event such as the annual Perfumery Excellence Awards, and, indeed, this year he launched a whole new award: “Pierre the Perfumer Award for Most Daring Fragrance (in any category)”. The idea being that at least one of the awards should be for risk-taking in fragrance creation; putting products on the market with scents that have the potential to be divisive (many legends have been born from love-or-hate fragrances; even entire fragrance families). We asked our members to nominate and vote for all the awards in advance of the symposium which meant the awards could be engraved in time for the gala dinner. Want to know who won?

Our blood cells have odourant receptors – what could this mean?

There is still so much we don’t understand about how our sense of smell works and a recent report on the findings of Peter Schieberle, Ph.D., suggests things are even weirder than we thought.

Our team recently discovered that blood cells – not only cells in the nose – have odorant receptors,” said Schieberle. “In the nose, these so-called receptors sense substances called odorants and translate them into an aroma that we interpret as pleasing or not pleasing in the brain. But surprisingly, there is growing evidence that also the heart, the lungs and many other non-olfactory organs have these receptors. And once a food is eaten, its components move from the stomach into the bloodstream. But does this mean that, for instance, the heart ‘smells’ the steak you just ate? We don’t know the answer to that question.”

What does this mean? We don’t know yet. Why would our blood cells need odorant receptors? Does this discovery offer any insight into why our flavour preferences differ?

The implications for flavourists and food technologists could be huge. The way we perceive foods depends on not only flavour and olfactory signals, but on texture, temperature and colour of the foods.

For example, baked beans and beans in foods like chili provide a “full,” rich mouth-feel. Adding the component of beans responsible for this texture to another food could give it the same sensation in the mouth, Schieberle explained. Natural components can also interact with substances in foods to create new sensations.

This research was presented on the 7th of April at the 245th National Meeting and Exposition of the American Chemical society.
