3) Aroma precursors
香味前体物
1.
In this thesis, four experiments were carried out to study the effects of strain, age, and body part on the concentrations of taste compounds and aroma precursors, and research the quantitative changes of those flavor-relating compounds during cooking, then investigate the components of flavor volatiles released from roasted and cooked meat samples.
本论文通过四个试验,研究了品种、日龄及屠体部位对鸡肉滋味物和香味前体物含量的影响,以及这些风味相关物在蒸煮过程中的含量变化,比较了优质肉鸡和速生型肉鸡在烘烤和蒸煮条件下释放的挥发性风味物组成和含量差异,并通过模拟体系探讨了各风味前体物对鸡肉香味形成的相对作用,旨在确定鸡肉主要风味前体物以及品种风味间差异形成的原因,为通过营养途径调控鸡肉品质提供基础资料。

茶叶中主要存在以苯甲醇、苯乙醇、芳樟醇及其氧化物(Ⅰ,Ⅱ,Ⅲ)、水杨酸甲酯、香叶醇等为配基的糖苷类香气前体,组成特点以萜烯醇类为主,且不同茶树品种其糖苷类香气前体配体含量存在较大的差异。
补充资料:酶前体
分子式:
CAS号:
性质:又称酶前体。酶的无活性的前体。通常必须在其他酶或酸的作用下,才能墨迹为具有活性的酶。如胰蛋白酶原经肠激酶激活,水解掉N端一个六肽,才转变成胰蛋白酶,用于促进胰脏功能。凝血酶原在促凝血球蛋白的作用下,转变成凝血酶,用作止血药物。
