研究了尼日尔曲霉漆酶对油炸鸡块、南瓜饼和油条后废食用油氧化指标及多环芳烃（PAH）和氧化多环芳烃（OPAH）含量的影响。酶解48 h后，不同样品的酸价基本保持不变，而过氧化值增加了423.80%~ 993.00%。样品中菲、9-芴酮和蒽-9，10-二酮的浓度分别为55.52-62.57、15.82-23.24和14.99-27.50 μg/kg，24 h后最大去除率分别为18.31%、26.92%和19.41%，最大去除率为29.24%。48 h后，分别为70.02%和62.88%。随着实验时间的延长，去除率也随之提高。并推测了这些化合物的降解途径。结果表明，漆酶可用于餐饮废油中特定PAH和OPAH的绿色去除。
In this study, we have investigated the effect of laccase from Aspergillus niger on the oxidation indices and polycyclic aromatic hydrocarbon (PAH) and oxygenated PAH (OPAH) content in waste cooking oil after frying nugget, pumpkin pie and youtiao. The acid value remained almost same while the peroxide value saw increment ranging from 423.80% to 993.00% in different samples after 48 h of enzymatic incubation. The concentration of phenanthrene, 9-fluorenone and anthracene-9,10-dione detected in our samples were respectively 55.52–62.57, 15.82–23.24 and 14.99–27.50 μg/kg and they were removed by a maximum of 18.31%, 26.92% and 19.41% after 24 h and 29.24%, 70.02% and 62.88% after 48 h. The removal ratio was higher with prolonged experiment duration. We also deduced the respective degradation pathway of these compounds. The result suggests that laccase could be used for green-removal of specified PAH and OPAH in waste cooking oil.
