Four bottles of "pearl" sample solution being chromium content detection,http://buntyn.stamina.jp. In a store to buy two pearl milk tea.<br>Recently, the media burst, pearl milk tea in the "pearl" generally contain gelatin ingredients. Young drink pearl milk tea containing gelatin and other illegal ingredients without leather? Reporters Contact Shandong Institute of Light Industry Analysis and Testing Center conducted experiments. As the plastic composed mainly of organic matter, its molecular structure is not easy to analyze test, heavy with the "poison capsule" into public view, "chrome" become part of the detection locked target.<br> <br>Before drying, and then dissolved metallic element<br> <br>April 18, reporters from the Cultural Road Lixia District of Jinan City,http://wx.jazzsynth.com/wxcgi/kizai/sunkizai.cgi?mode=form&no=40&page=2, Changqing University Science Park Commercial Street near the four tea shop bought four kinds of pearl milk tea, respectively.<br> <br>That night, the staff of four laboratory samples pre-inspection process. They first removed with a clean spoon tea in the "pearl", then rinse with water, then placed in a crucible. "Preparatory work for the experiment is more complex, we need to put water and organic matter contained in the pearl destroyed, to which the metal elements contained dissolved out,http://roda-store.jp, dubbed standard solution only after the experiment." Staff Wang Shanshan said.<br> <br>Pre-treatment process,scarpe hogan outlet, the need to "Pearl" was heated to 50 ℃ and kept for 24 hours until the water evaporated into a full box resistance furnace at a temperature of 600 ℃ burning seven hours, destroy organic matter. Then dry out after the remaining material from each of approximately 2g,http://tucchy.sakura.ne.jp/c/epad/epad.cgi?mode=view&no=6232&res=1&page=80, dubbed standard solution 100ml with 3ml of concentrated hydrochloric acid, dissolved metal ions.<br> <br>4 parts "pearl" chromium levels were higher than tap water<br> <br>April 23, reporters once again came to the Shandong Institute of Light Industry Testing Center analysis found that after black after the pre-treatment of the "pearl" has become almost transparent solution four bottles, bottle posted 1,2,http://www.es-project.net/maruyu/joyful2009121/joyful.cgi,3,scarpe hogan outlet,4 signs.<br> <br>Even in the inductor and plasma emission spectroscopy laboratory, laboratory assistant teacher Wei has launched inductance coupling and plasma emission spectrometer, machine rumbling sounded.<br> <br>Wei teacher, in order to perform experiments comparison, her first with the pipette solution to a higher concentration of chromium standard solution dubbed 5mg / l and showing a pale yellow solution.<br> <br>Then she chromium standard solution with a good emission spectrometer through a thin hose coupling the input inductor and plasma, after about 30 seconds, the test results presented by the computer next to a concentration of 5mg / l.<br> <br>In the same way,doudoune moncler pas cher, Wei teacher sequentially measured the submission of four bottles of "pearl" chromium content of the solution and a glass of tap water, 4 bottles of "Pearl" chromium content of the test results of the solution was 0.026mg / l, 0.005mg / l,http://www.chisa-club.com/cgi-bin/support/mail.cgi, 0.015mg / l, 0.017mg / l, and the chromium content in the water is only 0.002mg / l.<br> <br>Professor of Chemical and Pharmaceutical Engineering Science, Shandong Institute of Light Industry analysis Duden, four bottles of censorship pearl solution,scarpe hogan outlet, chromium content on the 1st bottle highest 0.026mg / l. He explained that the side edge computing,moncler sito ufficiale, since the 1st bottle solution is dried after about 2g of the "pearl" of acidifying come,http://www.bibet.com/home.php?mod=spacecp&ac=blog&blogid=, "that is,http://www.gigliocooking.com/ja/faqs/faq-general/68-general-faq4.html, the equivalent of 1 sample per 2g 'pearl' contains 0.0026mg chromium. Thus Looking back, then, the chromium content of the sample corresponds to the 1st Pearl 1.3mg / kg. "<br> <br>Chromium content standards dispute<br> <br>"In fact, currently being revised national standards." Shandong Province, CDC director of food and nutrition, said Zhao Jinshan, now the "limits of contaminants in food," was developed in 2005, and now look at some food categories are not sufficient refinement , the standard also requires some adjustment of pollutants. "For example, the chromium content standards currently there is controversy."<br> <br>For pearl milk tea pearl chromium content of 1.3 milligrams per kilogram is exceeded, Zhao Jinshan said that if in accordance with ordinary food perspective, then, should be less than 1 milligram per kilogram of this standard. "But even with industrial gelatin pearl is additive, it is used as accessories, pearl ingredient is what is important, because the chromium content because of the different types of food and different, this is related to the pearl classified as what type of food . "<br> <br>"Edible gelatin chromium content should not exceed 2mg / kg." Zhao Jinshan said that the reason may contain chromium, because plants and animals in fact, contain different amounts of trace elements, but they do not exceed the standard on basically no harm.<br> Share: welcome to comment I want to comment microblogging Recommended | hot microblogging today<br>
