The author:(作者)aaapublished in(发表于) 2013/12/18 9:44:19 Beijing more than Hotel napkin allegedly containing fluorescent agents， believed to be paper manufacturing
Recently, the Beijing news reporters from Beijing, 10 large and small restaurants to collect them with napkins and expert testing has found only two restaurants offer napkins no fluorescence.
Samples for journalists, international food packaging Association General Secretary Dong Jin lion 3 experiments were done, respectively, found that some restaurants with napkins containing a certain area of fluorescence agents and napkins after burning the color black, less fiber components, may be laced with impurities in the "waste paper" was made by. The well-known restaurant and fast-food restaurants, ordinary small restaurants, including McDonald 's, KFC, Yoshinoya, Yu rural people.
Cost is the main factor for manufacturers of waste paper. Golden Lion about Tung, napkins made of waste paper per ton price for 1500 Yuan, with pure straw pulp is 2,500 yuan per ton, while wood pulp manufacture, prices have nearly 5,000 yuan. After the producer of waste paper manufacturing napkins, I usually add talcum powder, calcium carbonate, some of them with fluorescent agent to whitening, weight, appearance and good.
Municipal industry and Commerce Bureau tips, fluorescent brightener to make paper white, are currently not unified its hazard awareness, standards for the napkin should be no portability fluorescent whitening agents, prevent fluorescence agents transferred to the human body.
Golden Lion Tung warned, buy napkins focused on packaging are "100% virgin wood pulp". At the restaurant, too white or too black, smell taste, shake out hair, look in the light "left eye" napkin, it is best to try not to use it.
Time and place: December 16, international food packaging Association
Experimental samples: journalists randomly collected from 10 restaurants napkin
"Test 1"
2 napkins no fluorescence
The experimental objective: identification of fluorescent whitening agent on napkins.
Experimental procedure: testers put napkins on the professional irradiation under the UV lamps, whether or not to display a bright blue. 10 kinds of napkins, only new hot road, green city and Yonghe King parkson stores two napkins show no fluorescence, McDonald 's, KFC napkins sporadic phosphor dots. Fluorescence of napkins from the biggest pipeline of "route through the snack bar".
"Expert analysis" Tung pointed out that Golden Lion, some sporadic phosphor dots on a paper napkin, generally may be brought in natural raw materials, consumers need not panic. Larger fluorescence, which napkins are either artificially added a fluorescent agent or use made of waste paper; research shows some fluorescence agents can cause leukemia.
"Test 2"
A napkin after burning black
The experimental objective: Verify that the napkin is doped with impurities.
Experiment: the researchers sampled 10 kinds of napkins, respectively, set it on fire, burning to see Ash after the color and status. Most of the ashes of the napkin solid gray wool, but the route through the snack bar napkins, the ash color black, like black knots, burning taste.
"Expert interpretation," said Dong jinshi, napkins not doping or the use of waste paper according to the provisions made napkin after burning the color black, which means it wasn't purely straw pulp made with wood pulp or paper of inorganic minerals such as talc, calcium carbonate, adding more. Napkins are not strong enough, easy to slag off lint, if you add too much, such as talcum powder, may contain heavy metals, wash the body may lead to skin irritation.
"Test 3"
3 napkin poor fiber quality
The experimental objective: view the strength of paper napkins.
Experimental procedure: 10 kinds of napkins with water jet wet, fully wet, and then try to pick up the napkin completely. Good quality napkin even soaked completely picked. Testing has found changesthe Szechuan Northeast dumpling, financial Street branch, HSBC pipeline pipeline route through the snack bar 3 restaurants use paper napkins, just soak had already broken out, unable to pick it up again.
"Expert analysis" Tung pointed out that Golden Lion, napkins carrying a broken one, description of the fibers in the paper component is relatively small, poor fiber quality, nor does it exclude the possibility of using recycled paper.

近日，新京报记者从北京10家大大小小的餐厅收集其提供的餐巾纸，请专家测试发现，仅两家餐馆提供的餐巾纸完全无荧光。
对记者提供的样品，国际食品包装协会秘书长董金狮分别做了3个实验，发现一些餐馆的餐巾纸含有一定面积的荧光剂，有的餐巾纸燃烧后颜色发黑，纤维成分少，可能为掺了杂质的“废纸”制作而成。这些餐厅既有知名餐厅和快餐店，也有普通小餐馆，包括麦当劳、肯德基、吉野家、渝乡人家等。
节约成本是厂家用废纸的主要因素。董金狮介绍，餐巾纸如用废纸造，每吨价格为1500元，用纯草浆则每吨2500元，而纯木浆制造，价格得近5000元。生产者用废纸制造餐巾纸后，一般都会加滑石粉、碳酸钙，有的还会用荧光剂来增白，这样重量又够，看起来卖相又好。
市工商局提示称，荧光增白剂可使纸张洁白，目前对其危害认识还不统一，标准规定了餐巾纸不应有可迁移性荧光增白剂，防止荧光剂转移至人体上。
董金狮提醒称，买餐巾纸重点要看包装上标注的是否为“100%原生木浆”。在餐馆，太白或太黑、闻起来有味道、抖起来掉毛、对着光线一看“漏眼”多的餐巾纸，最好都尽量别用。
时间地点：12月16日，国际食品包装协会
实验样品：记者随机从10家餐馆中收集的餐巾纸
【实验1】
2种餐巾纸完全无荧光
实验目的：查验餐巾纸上是否有荧光增白剂。
实验过程：测试人员把餐巾纸放到专业的紫外分析仪下照射，看是否显示亮蓝色。10种餐巾纸中，只有新辣道国瑞城店和永和大王百盛店两种餐巾纸显示完全没荧光，麦当劳、肯德基的餐巾纸有零星荧光点。荧光面积最大的餐巾纸来自丰管路上的“路通小吃店”。
【专家解读】董金狮指出，部分餐巾纸上的零星荧光点，一般可能是原材料自然带进来的，消费者不必恐慌。至于面积较大的荧光，其餐巾纸要么是人为添加了荧光剂，要么是使用废纸制作的；研究显示有一些荧光剂可能会导致白血病。
【实验2】
一种餐巾纸燃烧后发黑
实验目的：验证餐巾纸是否掺杂了杂质。
实验过程：实验人员取样10种餐巾纸，分别将其点燃，完全燃烧后查看灰烬颜色和状态。大部分餐巾的灰烬呈灰白色絮状，但路通小吃店的餐巾纸，其灰烬颜色却发黑，像黑疙瘩，烧起来有味道。
【专家解读】董金狮称，按照规定餐巾纸不能掺杂或使用废纸制造，餐巾纸燃烧后颜色发黑，说明不是用纯木浆或纯草浆制作的，纸里面的无机矿物质比如滑石粉、碳酸钙添加比较多。这样的餐巾纸不结实，易掉渣掉毛，如果添加过量的滑石粉等，可能含有重金属，沾身上可能导致皮肤过敏等。
【实验3】
3款餐巾纸纤维质量差
实验目的：查看餐巾纸的强度好坏。
实验过程：用水把10种餐巾纸喷湿，充分湿润，然后尝试把餐巾纸完整地拿起来。质量好的餐巾纸即使在浸湿后仍能完整拎起。测试发现，渝乡人家川菜馆金融街店、丰管路东北饺子馆、丰管路路通小吃店这3家餐馆使用的餐巾纸，刚浸湿就已残破得不成样子，根本无法再拿起来。
【专家解读】董金狮指出，餐巾纸一拎就破，说明纸里的纤维成分比较少，纤维质量比较差，也不排除使用再生废纸的可能性。
