Research on Migration of Butylated Hydroxytolune from Polyethylene Packaging Materials
The migration of the antioxidant, butylated hydroxytolune (BHT), from the high-density PE materials is researched by the GC-MS method. The initial BHT concentration is obtained through the ultrasonic hexane abstraction. This paper researches the rule of migration of BHT into fatty food simulacrum at 60 °C (the high temperature for short-time sterilization), 30 °C (the normal temperature for storage) and 4 °C (the low temperature for refrigeration).
