Chemical Properties |
2,6-Dimethylpyrazine has a nutty, coffee-like odor. |
Preparation |
By condensation of 1,2-diaminopropane, followed by column chromatography to separate the 2,6-methylpyrazine from the 2,5-dimethylpyrazine. |
Aroma threshold values |
Detection: 400 to 1500 ppb. Aroma characteristics at 1.0%: musty, cocoa powdery, tobacco, dry leaf tea, earthy mushroom cap and potato-like, meaty, roasted peanut shell, and coffee. |
Taste threshold values |
Taste characteristics at 5.0 ppm: musty and earthy, nutty peanut shell, cocoa powdery, earthy coffee, yeasty, woody, milk roasted peanut. |
