2-Acetylpyrazine Halal, Kosher
Odor Description:popcorn; nutty, bread crust
Taste Description:nutty
Used not only for popcorn type flavours, but also in roast nut flavours (hazelnut, peanut, almond), chocolate, bread and yeast type flavors. 2-Acetylpyrazine and 2-acetylthiazole both have aromas similar to the non-GRAS material 2-acetylpyrroline which is an important character impact compound in aromatic rice, bread crust and popcorn. Normal use levels in finished consumer product: 0.05-5 ppm. Council of Europe limits: foods (5 ppm); beverages (5 ppm).
