Study on Test Method of Carbon Number Distribution in White Oil
The carbon number distribution of white oil products reflects their performances,such as oxidation stability,ac-cumulation and absorption volume of food grade white oil in the body,and safety and immune efficacy of vaccine white oil,etc.In this paper,the test methods of carbon number distribution by GC-MS,simulated distillation and gel chromatogra-phy were compared in terms of principle and applicability.The results show that the carbon number distribution tested by GC-MS is consistent with that tested by simulated distillation method,and gel chromatography has its limitation due to its special mechanism.
