Abstract

The safety quality of plastic food containers for use in microwave ovens has been investigated. Samples made of polypropylene(PP),crystallized-polyethylene terephthalate (C-PET), polyolefin and composite material were collected from various supermarkets in Taipei.The samples were tested according to the "Hygiene Standards of Food Utensils, Containers and Packages" with the official methods issued by the Department of Health, except the olive oil leaching test method which was adapted from Japanese food regulations. Only one sample made of composite materials was found to violate the Standard because its residue on evaporation of 4% acetic acid leaching test exceeded the level of tolerance.
