本文介绍了什么是油脂氧化稳定实验，并对脱臭过程控制中油脂氧化稳定性进行了探讨。通过对脱臭蒸汽用量、进油流量、脱臭温度的单因素实验，并经过三个因素的正交实验，得出了脱臭过程控制中油脂氧化稳定性的最佳工艺条件。正交实验表明，在生产过程中油脂氧化稳定时间最长的工艺条件是：蒸汽用量70 KPa，进油流量24 m3/h，进油温度252 ℃，可使AOM值在3.17 h以上。

This paper introduced the Ransimat lab test, studied the oxidation stability conditions of deordorization process control. With the studies of deordorization steam flow, feed rate, feed temperature and three factor of orthogonal tests, the best oxidation stability technology conditions were determined.The orthogonal tests results indicated that the longest AOM technology conditions in production line were as follows that deordorization water steam flow 70 kPa, enter the oil discharge 24 m3/h, and deordorization temperature 252 ℃, under which the AOM could be more than 3.17 h.
