چکیده

Oils extracted from plants have been used since ancient times and in many cultures .frying oils are used in many countries all around the world including Iran. Therefore it is of great importance to ensure the safety of these food products which are usually delivered in polyethylene terephthalate (PET) bottles. This study has investigated the effect of storage time and temperature on the migration rate of phthalate compounds from PET bottle into frying oil. In more detail, migration rate of Bis (2-ethylhexyl) phthalate was measured in the 1st, 30th, and 60th days of storage within two different temperatures of 20 and 40 °C. At the both storage temperatures, increasing the storage time led to a statistically significant rise of the migration rate of phthalate compounds (p<0.1). Furthermore, it was determined that Bis (2-ethylhexyl) phthalate had a higher migration rate at 40 °C comparing to 20 °C.
