Mobility of alpha-tocopherol and BHT in LDPE in contact with fatty food simulants.
The migration/sorption behaviour of butylated hydroxytoluene (BHT) and alpha-tocopherol was studied in packaging material in contact with fatty food simulants. Two low-density polyethylene (LDPE) films, containing either BHT or alpha-tocopherol as antioxidants, were stored in contact with sunflower oil or 95% (v/v) ethanol. The antioxidant content was monitored in the films throughout a period of 7 weeks. The migration of alpha-tocopherol into the food simulants was slower than that of BHT. Since alpha-tocopherol was transferred from the film to the simulant to a lesser extent, it is considered to be a more stable antioxidant than BHT when used in an LDPE film in contact with 95% ethanol or sunflower oil.
