拉曼光谱法检测灵芝孢子油氧化酸败

采用拉曼光谱法直接监测灵芝孢子油中氧化酸败过程中不饱和双键特征峰的变化规律，研究了特征峰的强度与孢子油氧化酸败程度的关系。结果表明，特征峰强度随孢子油酸值、过氧化值的增加而下降，特征峰的面积与孢子油酸值之间存在着良好的线性关系，并进一步测定了灵芝孢子油氧化酸败的动力学参数。建立了用拉曼光谱快速检测灵芝孢子油氧化酸败度的新方法。对该方法的有效性进行评估，并用该方法筛选出有效的灵芝孢子油抗氧化剂。

Rapid Detection of Oxidative Rancidity of Ganoderma lucidum Spore Oil by Raman Spectroscopy

In this work, Raman spectroscopy was employed to directly monitor the changes in the characteristic peaks of
the unsaturated double bonds of Ganoderma lucidum spore oil during oxidative rancidity and the relationship between the
peak intensity and oxidative rancidity was discussed. Raman scattering intensity decreased with increasing acid value and
peroxide value and a linear correlation between acid value and the area of the characteristic peaks was determined. The
kinetic parameters for the oxidative rancidity of Ganoderma lucidum spore oil were also determined. As a result, a new
and fast approach for the detection of oxidative rancidity in Ganoderma lucidum spore oil by Raman spectroscopy was
established. This method was further validated and used to measure the kinetic parameters of oxidative rancidity and screen
antioxidants for Ganoderma lucidum spore oil.
