1) heterocyclic flavor compounds
杂环风味化合物
2) aroma compound
风味化合物
1.
It was found that neutral and weak acid conditions were convenient to the production of aroma compounds.
发现在本实验条件下中性偏酸性条件更有利于挥发性风味物质的形成, pH5下的挥发性物质总量最多且各类风味化合物的相对量也较大,pH7时总挥发物量较少但各类风味化合物的相对量高;强酸性条件下形成的风味物质相对含量低;碱性条件虽对含氮、硫、氧等杂原子的杂环化合物的形成较有利但其总挥发性成分的量低,使得各组分的绝对量不高,且pH9时生成大量的苯系物,其中有具有毒害作用的物质,在具体的生产实践中应加以注意。
3) meat flavor compounds
肉风味化合物
1.
Moreover,SDE has been interfaced to GC and other analytical instruments and provides a complementary or even superior alternative method for the preconcentration of meat flavor compounds.
通过同时蒸馏萃取法(SDE)和气相色谱-质谱联用(GC-MS)技术分析猪肉风味化合物,确立了同时蒸馏萃取法在肉类风味化合物分析中的优势:敏感、快速、样品用量少、操作简单、不用溶剂,而能直接与气相色谱等现代仪器联用的特点,使其在肉类风味分析上更具有强大的优势。
