对于经常点外卖的你，是不是有这样的疑问，纸质餐盒、塑料餐盒、饮料杯，以及木筷，这些一次性餐具安全吗？

　　For those of you who frequently order takeout, do you have the question of whether disposable tableware such as paper meal boxes, plastic meal boxes, beverage cups, and wooden chopsticks are safe 

　　有时外卖的饭菜凉了，还要用微波炉加热，会不会存在有害物质？

　　Sometimes the food for takeout gets cold and needs to be heated in a microwave. Is there any harmful substance present 

　　本期《专家有话说》将请江苏省食药安委食品安全专委会委员、南京市产品质量监督检验院正高级工程师申蓉为我们答疑解惑。一网络餐饮涉及的餐饮具分类

　　In this issue of 'Expert Talks', we will invite Shen Rong, a member of the Food Safety Special Committee of Jiangsu Provincial Food and Drug Safety Commission and a senior engineer of Nanjing Product Quality Supervision and Inspection Institute, to answer our questions and clarify our doubts. Classification of tableware involved in online catering

　　主要可分为3个大类：

　　It can be mainly divided into three categories:

　　1.食品接触用纸及纸制品，如纸盒、纸碗、纸杯、纸吸管等；

　　1. Food contact paper and paper products, such as paper boxes, paper bowls, paper cups, paper straws, etc;

　　2.塑料一次性餐饮具，如塑料打包盒、塑料盒盖、塑料叉/勺/吸管等；

　　2. Disposable plastic tableware, such as plastic packaging boxes, plastic box covers, plastic forks/spoons/straws, etc;

　　3.一次性竹木筷，如竹筷、木筷。

　　3. Disposable bamboo and wooden chopsticks, such as bamboo chopsticks and wooden chopsticks.

　　二一次性餐饮具可能存在的食品安全风险

　　Possible food safety risks associated with disposable tableware

　　因材质不同、特性不同，一次性餐饮具可能存在的食品安全风险主要有：

　　Due to different materials and characteristics, the potential food safety risks of disposable tableware mainly include:

　　1.荧光性物质、二氧化硫不合格。使用劣质原料或不合格的回收材料生产的纸质餐具、一次性筷子，往往通过添加荧光增白剂、硫化物用于“美化”外观，造成荧光性物质、二氧化硫不合格，可能对人体健康带来危害。

　　1. Fluorescent substances and sulfur dioxide are not qualified. Paper tableware and disposable chopsticks produced using inferior raw materials or substandard recycled materials are often beautified by adding fluorescent whitening agents and sulfides, resulting in substandard fluorescent substances and sulfur dioxide, which may pose a threat to human health.

　　2.大肠菌群、霉菌等微生物不合格。餐饮具如果灭菌不彻底，或是存放过程中受到污染，导致微生物超标，可能会引起消费者呕吐、腹泻，及肠胃感染。

　　2. The coliform bacteria, mold and other microorganisms are not qualified. If tableware is not thoroughly sterilized or contaminated during storage, resulting in excessive microorganisms, it may cause consumers to vomit, diarrhea, and gastrointestinal infections.

　　3.负重性能、跌落性能、杯身挺度不合格。质量不符合标准的餐具，很有可能在使用过程中破损破裂，不仅会污染食物，也可能会烫伤消费者。

　　3. The load-bearing performance, drop performance, and cup body stiffness are not qualified. Tableware that does not meet the quality standards is likely to be damaged or broken during use, which not only pollutes the food but may also burn consumers.

　　4.标签标识不规范。如未标注“食品接触用”等用语或图形、未进行材质或使用温度提示、产品标准标注错误等不仅会带来追溯难的问题，还会误导使用者，从而产生食品安全风险。三一次性餐饮具使用提示

　　4. The label identification is not standardized. Failure to label terms or graphics such as "for food contact", failure to provide material or temperature warnings, and incorrect labeling of product standards can not only lead to difficulties in tracing, but also mislead users, resulting in food safety risks. Three tips for using disposable tableware

　　1.一看二闻三摸。收到外卖餐食后，注意观察塑料餐饮具底部带箭头的三角形标志，其数字代表了器皿的材质（见下表），不同材质的塑料餐盒有不同的使用温度，以避免因使用不当导致餐盒变形、开裂或释放有害物质。

　　1. Look, smell, and touch. After receiving takeout meals, pay attention to the triangular symbol with an arrow at the bottom of the plastic tableware, which represents the material of the container (see table below). Plastic lunch boxes of different materials have different operating temperatures to avoid deformation, cracking, or release of harmful substances due to improper use.

　　合格的一次性餐饮具仅凭鼻子应闻不到异味，如果一次性筷子用硫磺熏过，会有一股淡淡的酸味，最好不要使用。

　　Qualified disposable tableware should not have any odor detected by the nose alone. If disposable chopsticks have been smoked with sulfur, there will be a slight sour taste, so it is best not to use them.

　　符合要求的一次性餐饮具表面光滑平整、厚薄均匀，且无杂质，若遇到毛糙、色泽不均的餐饮具，尽量避免食用其中的食品。

　　Disposable tableware that meets the requirements should have a smooth and even surface, uniform thickness, and no impurities. If encountering rough or uneven colored tableware, try to avoid consuming the food inside as much as possible.

　　2.谨慎使用微波炉复热。外卖食品最好现点现食，若要使用微波炉复热时应注意，餐盒标识上是否为PP（聚丙烯）材质，或是否有可使用微波炉加热的标注（PP材质的熔点为167℃，是可以使用微波加热的一次性餐盒，外包装标注为5号）。需注意有些餐盒的盒身为5号PP材质，盒盖可能是1号PE材质，则盒盖不能微波加热。若在加热后餐盒变形或产生异味，请不要食用餐盒中的食品。

　　2. Use microwave oven for reheating with caution. It is best to order takeout food immediately. When using a microwave oven for reheating, attention should be paid to whether the food box label is made of PP (polypropylene) material or whether there is a label indicating that it can be heated in a microwave oven (PP material has a melting point of 167 ℃ and is a disposable food box that can be heated in a microwave oven. The outer packaging is labeled as size 5). It should be noted that some meal boxes have a body made of No. 5 PP material, and the lid may be made of No. 1 PE material, so the lid cannot be microwave heated. If the food box deforms or produces an odor after heating, please do not consume the food in the box.

　　3.不建议重复使用。一次性餐饮具经反复盛装食品会影响其耐用指标，故不建议消费者重复使用，特别是曾放过油脂较大或高温食品的餐饮具，建议即用即弃。

　　3. It is not recommended to reuse. Disposable tableware that has been repeatedly used to hold food can affect its durability index, so it is not recommended for consumers to reuse it, especially tableware that has been used to hold high-fat or high-temperature food. It is recommended to use it immediately and discard it.
