| General comment | At 0.10 % in dipropylene glycol. earthy bell pepper raw potato galbanum |
| Besides peppers and beans, this pyrazine, which consists of a mixture of isomers, occurs naturally in potatoes and a number of other vegetables and also has a raw-potato, earthy quality. Even at 0.1% this is a very powerful material that can easily dominate your blend, so use with caution in any blend where an original green-note is desired, or to add realism to galbanum, tomato and other green or fruity accords. | Bell-pepper, earthy, green-pea, raw potato |
