Qu'est-ce que l'ac\u00e9to\u00efne ?<\/strong><\/span><\/p>\n

L'ac\u00e9to\u00efne, \u00e9galement connue sous le nom de 3-hydroxybutanone ou ac\u00e9tyl m\u00e9thyl carbinol, est un compos\u00e9 organique de formule CH3CH(OH)C(O)CH3. C'est un liquide incolore avec une agr\u00e9able odeur de beurre. C'est chiral. La forme produite par les bact\u00e9ries est la (R)-ac\u00e9to\u00efne.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

L'ac\u00e9to\u00efne, avec le diac\u00e9tyle, est l'un des compos\u00e9s qui donne au beurre sa saveur caract\u00e9ristique. Pour cette raison, les fabricants d'huiles partiellement hydrog\u00e9n\u00e9es ajoutent g\u00e9n\u00e9ralement un ar\u00f4me de beurre artificiel - ac\u00e9to\u00efne et diac\u00e9tyle - (ainsi que du b\u00eata-carot\u00e8ne pour la couleur jaune) au produit final.
\nL'ac\u00e9to\u00efne peut \u00eatre trouv\u00e9e dans les pommes, le yogourt, les asperges, les cassis, les m\u00fbres, le bl\u00e9, le brocoli, les choux de Bruxelles, les cantaloups et le sirop d'\u00e9rable
\nL'ac\u00e9to\u00efne est utilis\u00e9e comme ar\u00f4me alimentaire (dans les produits de boulangerie) et comme parfum.
\nIl est utilis\u00e9 dans les liquides pour cigarettes \u00e9lectroniques pour donner un go\u00fbt de beurre ou de caramel.<\/p>","protected":false},"excerpt":{"rendered":"
