一般描述

2-异丁基-3-甲氧基吡嗪是甜椒的主要风味/香气成分。它也存在于新鲜的墨西哥胡椒和烤土豆中。

应用


  • RIFM香料成分安全性评价，2-异丁基-3-甲氧基吡嗪，中国科学院登记号24683-00-9。：该安全性评估审查了2-异丁基-3-甲氧基吡嗪的毒理学数据，确保其在香料中的安全使用（Api et al., 2024）。

  • 对葡萄藤进行源库操作对葡萄浆果和葡萄酒中的黄酮类化合物以及香气有重大影响，这些影响超出了浆果中糖分积累的变化。：本文讨论了2-异丁基-3-甲氧基吡嗪对葡萄酒香气的影响，重点讨论了农业实践及其对葡萄品质的影响（Martínez-Lüscher and Kurtural, 2023）。
