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.
