Study on hydrogen - tritium exchange reaction of tritiated tetramethyl pyrazine 液相氚化川芎嗪的氚氫交換反應(yīng)
2 - acetyl pyrazine 2 -乙酰基吡嗪
The variety and high content of pyrazine compounds in maotai - flavor liquor are regarded as the products of maillard reaction so far 摘要迄今為止,普遍認為醬香型白酒中種類眾多、含量很高的吡嗪類化合物是通過美拉德反應(yīng)途徑產(chǎn)生的。
However , related data show that besides maillard reaction , the microbial metabolic pathway , the protein and amino acids healing processes can also produce pyrazine compounds 但據(jù)有關(guān)資料表明,除了“美拉德反應(yīng)途徑”外還有“微生物代謝產(chǎn)物途徑、蛋白質(zhì)加熱分解途徑和氨基酸類的加熱分解途徑”也可以產(chǎn)生吡嗪類化合物。
