      外卖食品的增加大大增加了一次性餐具的使用。目前,市场主要集中在塑料午餐盒,虽然一些高档餐厅将使用锡箔纸和盒子。一次性餐具究竟是否有害,暂时还不能一概而论,要看一次性餐具的材料是什么,需要把握的食物是在什么样的状态。

  The increase in take out food has greatly increased the use of disposable tableware. At present, the market is mainly focused on plastic lunch boxes, although some high-end restaurants will use tin foil and boxes. Whether disposable tableware is harmful or not can not be generalized for the time being. It depends on the material of disposable tableware and the state of the food to be grasped.
  由于一次性餐具以塑料饭盒为主,所以来看塑料餐具会危害健康。餐馆里的大多数盒子是用聚丙烯(PP)制成的,这种材料可以用来做饭。
  Because disposable tableware is mainly made of plastic lunch box, it will do harm to health. Most of the boxes in the restaurant are made of polypropylene (PP), which can be used for cooking.
  国家对食品接触用塑料有标准,即GB 4806.7-2016《食品接触用塑料材料及制品》,规定的理化指标如下:
  The national standard for plastics used in contact with food is GB 4806.7-2016 plastic materials and products used in contact with food. The specified physical and chemical indexes are as follows:
玉米淀粉颗粒
  1. 总迁移
  1. total migration
  接触食品用塑料可能有各种各样的有害物质(主要增塑剂、抗氧化剂、稳定剂等)向食品迁移,这个项目是使用各种各样的食品模拟的浸浸液蒸发而干燥,让样品浸泡的挥发物总量迁移。
  In contact with plastic for food, there may be a variety of harmful substances (mainly plasticizers, antioxidants, stabilizers, etc.) migrating to food. This project is to use a variety of food simulated immersion solution to evaporate and dry, so as to transfer the total amount of volatile matter soaked in the sample.
  2. 高锰酸钾的消耗
  2. Consumption of potassium permanganate
  高锰酸钾的消耗测试是将样品浸泡在蒸馏水中,所有的有机小分子都可以很容易地溶解在水中形成混合物。混合物用高度氧化的高锰酸钾溶液滴定,其中所有的有机小分子都被氧化,而水不参与化学反应。
  The consumption test of potassium permanganate is to immerse the sample in distilled water, and all organic small molecules can be easily dissolved in water to form a mixture. The mixture was titrated with highly oxidized potassium permanganate solution, in which all the small organic molecules were oxidized, while water did not participate in the chemical reaction.
  3.重金属
  3. heavy metals
  与食品接触的塑料可能含有重金属,主要来自热稳定剂、着色剂或一些劣质材料。这个项目测量塑料中重金属的含量。
  Plastics in contact with food may contain heavy metals, mainly from heat stabilizers, colorants or some inferior materials. This project measures the content of heavy metals in plastics.
  数据显示,在正常使用环境下,塑料中的有害物质不会迁移到食物中。从测试结果来看,这种材料PP(聚丙烯)确实是相对安全的。不仅如此,塑料盒还可以用微波炉加热。还有聚苯乙烯(PS),由苯乙烯聚合而成,通常用于方便面盒和快餐盒。耐热耐寒,但温度太高将释放有害物质,所以不要把碗方便面放入微波炉加热,不要用它来填补滚烫的食物,同时也不能含有强酸(如果汁)和强碱性物质,否则会释放一些有害物质,或者不是很好。
  Data show that under normal use environment, harmful substances in plastic will not migrate to food. From the test results, this material PP (polypropylene) is indeed relatively safe. Not only that, plastic boxes can also be heated in microwave ovens. And polystyrene (PS), polymerized from styrene, is usually used in instant noodle boxes and fast food boxes. Heat and cold resistance, but too high temperature will release harmful substances, so do not put the bowl of instant noodles into the microwave oven for heating, do not use it to fill the hot food, and do not contain strong acid (if juice) and strong alkaline substances, otherwise it will release some harmful substances, or not very good.
  虽然一次性餐具为生活带来了许多方便,但也让自然环境相对巨大代价,塑料餐具等很长一段时间不容易腐败,如果作为一个垃圾焚化厂,除了增加垃圾也导数空气污染问题,人们可能会阻止排水沟渠或杀死动物吃,有害生物的环境。
  Although disposable tableware brings many conveniences to life, it also makes the natural environment relatively expensive. Plastic tableware and other tableware are not easy to corrupt for a long time. If as a waste incineration plant, in addition to increasing garbage, it also leads to air pollution problems. People may prevent the drainage ditch or kill animals to eat and harmful organisms.
  塑料已经使用一次性餐具的安全性提出质疑,一些塑料产品制造过程中,为了使塑料色彩斑斓的外表或使塑料更稳定,将添加塑化剂,染料含有重金属和稳定剂,阻燃剂,如化工、高温或脂肪的食物可能会释放有害物质。泡发饭盒包装热的食物会有气味,释放有害物质,有的还会过热变形,这还不够使用或不使用的好。
  The safety of disposable tableware has been questioned. In the manufacturing process of some plastic products, in order to make the plastic colorful appearance or make the plastic more stable, plasticizers will be added, dyes containing heavy metals and stabilizers, and flame retardants, such as chemicals, high temperature or fat, may release harmful substances. The hot food in the box will smell, release harmful substances, and some will overheat and deform, which is not good enough for use or not.
  由于一次性塑料餐具在使用后被丢弃,往往造成资源的浪费,增加了垃圾的处理成本。大量塑料垃圾的产生增加了环境自我修复的负担。希望“零塑料”完全降解的环保餐具的概念,能在实际行动上,为地球环境做一份力量。
  Because disposable plastic tableware is discarded after use, it often causes waste of resources and increases the cost of garbage disposal. A large number of plastic waste increases the burden of environmental self-healing. It is hoped that the concept of "Zero plastic" environmental protection tableware can make a contribution to the earth's environment in practice.
  而随着人类越来越重视环保的观念,快速降解的餐具必将成为未来的主流。相信一次性食品盒会变得越来越环保,越来越健康。
  With more and more attention to the concept of environmental protection, fast degradation of tableware will become the mainstream in the future. I believe that disposable food boxes will become more and more environmentally friendly and healthy.
