2-Acetyl Pyrazine 1%

Description:
The immediate impression of hot popcorn, toasted grain, and bread crust fresh from the oven. 2-Acetylpyrazine is one of the most characterful materials in the roasted-gourmand palette: intensely nutty, warm, and faintly oily, with nuances that can suggest toasted corn, cooked rice, and savoury pandan.

Used with precision, it brings convincing depth to gourmand and regional accords—from roasted rice, coffee, and baked goods to palm sugar and bunga rampai compositions. Its strength lies not only in creating a recognisable roasted note, but also in adding warmth and texture at trace levels.

In its neat form, 2-Acetylpyrazine is a crystalline solid. KSA supplies it as a 1% dilution, making it easier to handle and weigh accurately at the bench.

Its odour threshold is exceptionally low. Even at 1%, a small excess can quickly dominate a composition and shift the profile towards burnt, oily, or plastic-like territory. Begin below what instinct suggests and increase gradually.
