| Nutty Pyrazine |
| Odor Description: | Sweet, nutty, roasted, earthy, coffee, popcorn As with all pyrazines this is used in tiny traces – Nutty Pyrazine at 0.1% in IPM has a powerful, sweet, nutty, roasted, toasted, earthy, grainy, coffee and popcorn odour with savoury nuances.
Even at this dilution this is a very powerful and diffusive material, that is present in the natural aroma of coffee as well as a range of nuts. Often used in the flavouring industry to enhance the scent of popcorn.
In fragrances most common as part of a chocolate or other gourmand aroma but can also be used as part of a nutty or smoky accord. |
