Headspace gas chromatography-mass spectrometry (GC-MS) has been adapted for the efficient determination of furan in foods. Levels of furan in various foods were measured in order to identify the products that contribute most to the human intake of furan. Highest amounts were found in products that were heat treated in sealed containers such as jarred and canned food products and in crusty and dry products such as snacks, biscuits, bread crust, roasted wheat flour and roasted coffee beans. Of the analysed jarred baby food products those containing only meat and starch from rice and corn had low levels of furan. In addition, the fruit products showed similar low levels. Clearly higher concentrations were found in the vegetable and vegetable-meat products. For the adult population coffee seems to be an important product with respect to furan intake. Coffee brews from espresso-type machines had considerably higher amounts of furan than other coffee brews. This type of coffee is considered by experts to have the best coffee aroma. It is assumed that for regular coffee consumers coffee is the most important source of furan intake.
顶空气相色谱 - 质谱联用(GC-MS)已被用于高效测定食品中的呋喃。测定了各类食品中的呋喃含量,以确定对人类呋喃摄入量贡献最大的产品。在密封容器中经过热处理的产品,如罐装和瓶装食品,以及酥脆和干燥的产品,如零食、饼干、面包皮、烤小麦粉和咖啡豆中,发现呋喃含量最高。在分析的瓶装婴儿食品中,仅含有肉类以及大米和玉米淀粉的产品呋喃含量较低。此外,水果产品的呋喃含量也较低。蔬菜和蔬菜 - 肉类产品中的呋喃浓度明显更高。对于成年人群体而言,咖啡似乎是呋喃摄入的重要来源。意式浓缩咖啡机冲泡的咖啡中呋喃含量明显高于其他咖啡冲泡方式。专家认为这种咖啡具有最佳的咖啡香气。据推测,对于经常喝咖啡的人来说,咖啡是呋喃摄入的最重要来源。
