摘  要:
为了探究风鸭产品加工的关键工艺因子温度、Na Cl含量以及p H值对鸭肉中脂肪氧合酶(LOX)活性的综合影响,通过体外模拟风鸭加工的工艺条件,用正交试验方法系统研究了温度、Na Cl含量、p H值对LOX活性的交互作用。结果表明,温度、Na Cl含量以及p H值三者对鸭肉LOX活性的影响存在显著交互效应(P<0.01)。温度和Na Cl含量对鸭肉LOX活性影响的临界值都随着另一方的增加而线性降低;温度对LOX影响的临界值随着p H值的增大而升高,Na Cl含量临界值随着p H值的增大而降低。因此,在风鸭加工过程的起始阶段降低腌制用盐量,提高温度能够提高鸭肉中LOX活性。

摘  要:
In order to investigate the interactive effects of the critical process factors(as temperature,Na Cl content and p H) of cured duck processing on duck lipoxygenase(LOX) activity,an orthogonal experiment by in vitro simulated wind duck processing conditions was systematically investigated.The results showed that temperature,Na Cl content and p H had significant interactive effect on the LOX activity(P < 0.01).The thresholds of the content of Na Cl affecting duck LOX activity exhibited a linear decrease with the increasing of temperature,while the thresholds of temperature would rise with the increasing of p H.The activity of LOX increased with the decreasing of salt consumption and the rising of temperature in the initial stage of processing.
