实验中我先进行了样品处理,通过加热模拟了暖柜饮料所处的温度及加热时间,并进行样品的萃取与浓缩,然后用气相色谱-质谱联用检测,得出其中蕴含的DEHP的浓度.
经过实验,我得出了以下结论：从温度看,加热80℃时塑料瓶液体中的DEHP浓度最大,其次为60℃,而40℃几乎无DEHP释放.可见,加热温度对塑料瓶装饮料的DEHP浓度有一定程度的影响.加热温度越高,释放DEHP浓度越高.建议便利店、地铁站放置塑料饮品的暖柜温度不高于80℃.
从时间看,持续半天、2天、7天,基本无DEHP释放.加热3周时DEHP浓度会有一个飞跃性的增长.根据《食品容器、包装材料用添加剂使用卫生标准》中食品、食品添加剂中的DEHP最大残留量为1.5mg/kg.在80℃持续加热3周的塑料瓶体塑化剂DEHP溶出量接近卫生标准的可允许最大残留量.
由此可见,在持续加热情况下,塑料瓶装热饮的安全饮用期限为3周.建议地铁站自动饮料机内塑料瓶装饮料在上架前统一张贴“饮料食用安全期限”的标志,为人们选购健康饮品作参考.
在这个“民以食为天”的时代,在这个越来越多人关注食品健康,关注保健养生的潮流中,我们更应该关注这些身边的点点滴滴,用多一点的留意,多一分的深入为大家扫清这些食品中的隐忧,温暖中的危机.

Experiment I first has carried on the sample processing,simulated by heat warming cabinet beverage of temperature and heating time,and extraction and concentration of the sample,then gas chromatography - mass spectrometry detection,which contain the DEHP concentration.Drew the following conclusions:through the experiment,I look from temperature,plastic bottles of liquid when heated to 80 ℃ the DEHP concentration is the largest,followed by 60 ℃,40 ℃ and almost no DEHP released.Visible,DEHP concentrations of heating temperature on the plastic bottle has a certain degree of influence.The higher the heating temperature,the higher the concentration of DEHP release.Suggest a convenience store,subway station place plastic drinks warm ark temperature is not higher than 80 ℃.From the time for half a day,2 days,7 days,the basic no DEHP released.Heat 3 weeks DEHP concentration has a leap in the growth.According to the food containers and packaging materials used additives health standard "in the DEHP maximum residue in the food,food additives is 1.5 mg/kg.Heating at 80 ℃ for 3 weeks the plastic bottles of plasticizer DEHP dissolution amount close to the hygiene standards allow maximum residue.Thus,under the condition of continuous heating,plastic bottles of hot drinks safe drinking for 3 weeks.Suggest metro station automatic drink machines,plastic bottled drinks in front of the shelves unified posted a sign of "beverage consumption safety period",for people to choose health drink for reference.In this era of "yen",in this more and more people pay attention to food health,pay attention to the health care keeping in good health,we should pay attention to these dribs and drabs around him,with a little more attention to,more in-depth to clear the concern of these foods,warm in the crisis.
