Hide the hidden danger in the moon cake Tuoli 11 samples and 10 detection plasticizer compositions
Luxuriant and beautiful and Jean is a pair of cousins, they think, select the moon cake, it is certainly that taste is the most important! All sisters, but glorious, mere Great Britain thinks, select the moon cake, the most important one is not the taste, but the brand. Only choose the leading brand product, quality is guaranteed. In fact, two view of sister these, a lot of the intersection of suitable person and question that moon cake consider at first too. In fact, luxuriant and beautiful, Jean and glorious, mere Great Britain are when selecting the moon cake, have justed think of brand and taste, and ignored an important problem: It is this small moon cake that is held. Don't look down upon this small plastic box, but contain the big knowledge among them!, some moon cakes hold and probably contain plasticizer! Plasticizer? This has given two pairs of sisters who chose the moon cake a start! In the moon cake sold on the market, how many moon cakes are there to ask to contain plasticizer? What kind of moon cake Tuoli on earth to contain plasticizer? The reporter gives this task to luxuriant and beautiful, Jean and glorious, mere Great Britain, let them select the moon cake everywhere, and consider it is safe and reliable that the moon cake is held at first. Soon, two sister these elect 15 moon cake, each kind of moon cake buy 3, among them, there are moon cakes of old established firm, the moon cake which some small producers produced. Subsequently, the reporter washes the moon cake had bringing them, the physics and chemistry of Beijing analyze test center Yongfeng station after coming. It is to get moon cakes out to measure personnel, then hold the moon cake to stick and encode. These moon cake has the transparent one to ask, has the milky white one, deep yellow, pale yellow and having a metallic one. Quality is similar that they look, but is not suitable for holding the moon cake? We measure the material that these moon cakes asked at first. What material is held to measure these moon cakes? Measure personnel: Hold the moon cake to take out at first, then after cutting with the scissors then puts on the infrared spectrocomparator then cuts the scanning of the total reflection through declining then we can obtain itses after polishing the sample clean Table picture information then can analyze whether there aren't concrete material of it at pieces of table picture we through this, then put them into this instrument in turn and measure personnel to tell us, measure the material that 15 kinds of moon cakes held, probably takes about 30 minutes. 30 minutes later, it is so fresh as to make to measure the result! Measure personnel: We adopt infrared spectrocomparator, ask sample go on materials analyze to 15 moon cake, (PS) that among them 9 samples are the polystyrene material ,(PVC) that 5 samples are the polyvinyl chloride material ,A sample is made of polypropylene material. In the moon cakes of 15 kinds of types are held, there is one PP material, there are 9 PS material, there are 5 PVC material. Then, PP, PS, what differences do these three kinds of materials of PVC have? Are they all suitable for holding the moon cake? International the intersection of food packing and the intersection of Deputy Chairman and gold lion Dong of association tell reporter whether qualified PP, PS plastics package can be used for holding the moon cake, however, PVC can only pack the ordinary food, can't be used for cooking the moon cake to hold. Why? Gold lion Dong: As PVC, it allow, contact containing oil food generally, include, mould, take pharmaceutical inside the it, the moon cake is absolutely the food with rich oil content, exposed to the packing materials which contain plasticizer with it, then plasticizer is very apt to go to migrate to the moon cake, people will take into the plasticizer virtually. Dong Beijing lion tell us whether plastic products of PVC in the course of manufacturing, in order to increase flexibility, need to add a material - -Plasticizer, addition level is probably 30%. Plasticizer is very apt to dissolve and enter in the fat food, bring to human body and endanger potentially. And the plastics package of PP, PS, does not need to add plasticizer in process of production. Gold lion Dong: PP ask polypropylene have one ask PS, call polystyrene, two the intersection of material and own it these have certain transparency, there are certain flexibility and rigidity, the only material can meet requirements for security of our parcel food. So, usually, it doesn't need to add plasticizer to produce PP and PS and pack. Then, four moon cakes which consumers chose are held, whether contain plasticizer inside? What kind is their own content? Measure two various moon cake mould, take content of pharmaceutical, next, measure personnel, choose 11 moon cakes ask ask, cut them into small fragments, while putting into container after weighing, then pass a little more methods, plasticizer that may contain while holding the moon cake is drawn out. Measure personnel: This experiment is two determination of first sour ester of benzene of neighbor in the food packing materials, through this experiment, we can test in much food packing materials, whether contain 2 first sour ester of benzene of neighbor, because it belongs to a kind of plasticizer. Two days later, measured the result. Measure personnel: Ask sample to 11 moon cake according to the intersection of national standard and method, go on residue amount of plasticizer determine, among them 10 samples detect and contain DEHP ' Plasticizer) The composition, a sample has not detected DEHP (plasticizer) Composition. This result makes people shocked, it is accepted that 11 kinds of moon cakes of detection are held, the moon cake of only a PS material is held not to include plasticizer, 10 kinds of other moon cakes are held, no matter PP, the moon cake of PS or PVC is held, all contain plasticizer - -DEHP. And according to " food container, packing materials will use the sanitary standard with additive " which Ministry of Public Health, national standard committee will issue in 2008, mould, take pharmaceutical like DEHP, etc, can only it used ins to be fat packaging of food. And the moon cake belongs to bigger fat food oilily, obviously can not use the packaging which contain DEHP this kind of plasticizer. And the more startling one is, according to the national standard, in the food packing materials, plasticizer DEHP maximum remaining amount is as 1.5 milligrams per kilogram, and in the moon cake measured this time is held, unexpectedly three kinds have reached 1227 milligrams per kilogram respectively, 1043 milligrams per kilogram and 880 milligrams per kilogram. Since PP, PS packs in process of production, does not need to add plasticizer, PP then measured this time, the moon cake of PS material is held, how could find plasticizer? Gold lion Dong: The first kind is that enterprises used plasticizer in violation of rules and regulations, originally needn't add, the country does not allow adding either, then you add, this has been used in violation of rules and regulations by an enterprise, the second may have used the waste plastics, because of some waste plastics, the source is not very clear, some were abolished originally Plastics, hold industrial products, it is sometimes in order to change performance inside the industrial products, unless also it can add pieces of plasticizer, after not retrieving back,it can and food grade (plastics) Mix ' Use) .
