产品说明 一般描述 2,4,5-Trimethyloxazole is an important heterocyclic flavor compound that generally occurs in coffee and cocoa. It is reported to be present in meat and roasted peanuts due to its formation by the reaction between 2,3-butanedione and alanine or cysteine due to Strecker′s degradation. 应用 可能的用途：可用于巧克力、荷兰可可、咖啡、麦芽酒、烤面包和各种肉香风味的香精中。 包装 50, 250 g in poly bottle
1 kg in poly bottle 生化/生理作用 香味阈值为·1.0%：略微有点像吡啶，烤植物和烤荷兰可可的气味，混以轻微的坚果香。
味觉阈值为 1ppm：烤甜可可、咖啡、巧克力、微微烤焦的牛肉香、蛋白质以及绿色蔬菜的味道。 其他说明 天然存在：存在于熟牛肉、可可、熟猪肉、炸薯条、自溶酵母、煮鸡蛋和炸鸡中。 基本信息 | 经验(实验)分子式 | C6H9NO | | 分子量 | 111.14 | | FEMA编号 | 4394 | | EC 号 | 243-952-4 | | MDL编号 | MFCD00005308 | | PubChem化学物质编号 | 329830710 | | Flavis编号 | 13.169 | | NACRES | NA.21 |
