为什么泡沫杯盛热汤会有毒?

“What happens when we add hot food or drinks to Polystyrene?

Polystyrene contains the toxic substances Styrene and Benzene, suspected carcinogens and neurotoxins that are hazardous to humans. Hot foods and liquids actually start a partial breakdown of the Styrofoam, causing some toxins to be absorbed into our bloodstream and tissue.

Polystyrene food containers leach the toxin Styrene when they come into contact with warm food or drink, alcohol, oils and acidic foods causing human contamination and pose a health risk to people.  Avoid drinking tea with lemon, coffee with dairy cream, fruit juices, alcoholic beverages and wine from Styrofoam cups. Red wine will instantly dissolve the Styrene monomer.  Do not eat oily foods from Styrofoam containers.

Most interesting is the degradation of food that contains vitamin A (beta-carotene). In packaged foods with the addition of heat (such as microwave temperatures), vitamin A will decompose and produce m-xylene, toluene, and 2,6-dimethylnaphthalene. Toluene will aggressively dissolve polystyrene. This renders polystyrene as an unsuitable package for containing or micro waving products that contain vitamin A.”——–by “Future Centre Trust”

泡沫容器有毒, 原因是许多食物中有维它命A,在加热时,维它命A会分解产生m-xylene, tolune, and 2,6-dimethylnaphthalene. Tolune 是泡沫材料的极好溶剂。泡沫材料中有苯乙烯, 这样苯乙烯单体就会进入汤水中,被我们喝进去。从而存留体内,以致于致癌。而这些食物包括:柠檬饮料, 咖啡饮料,日常奶制品,水果饮料,酒精饮料,葡萄酒。
