高温下外卖包装安全吗

Core Viewpoint - The discussion around the potential release of harmful substances from food delivery packaging at high temperatures has gained attention, with experts clarifying the actual risks involved [1][2]. Group 1: Market Overview - Online food delivery users in China have reached 545 million, making it the largest food delivery market globally [1]. Group 2: Microplastics - Microplastics are defined as plastic particles smaller than 5 millimeters, which can enter the human body through food and potentially affect health [1]. - Research indicates that while microplastics can impact biological organisms in experimental settings, the concentrations used in studies are significantly higher than what humans encounter in natural environments [2]. - A study published in the Journal of Hazardous Materials found that pouring hot water at around 85°C into disposable paper cups can release approximately 25,000 microplastic particles after 15 minutes [2]. Group 3: Perfluorinated Compounds - Perfluorinated compounds are synthetic organic substances known for their chemical stability and resistance to high temperatures, previously used in industrial production and consumer goods [2]. - These compounds can accumulate in the food chain and may cause liver damage, disrupt endocrine functions, and affect reproductive development if they persist in the human body [2]. - Current regulations have led to a reduction in the use of perfluorinated compounds in disposable paper cups, which now primarily use PE or biodegradable plastic coatings [2]. Group 4: Safety Recommendations - To ensure food safety, it is advised to choose food packaging that meets national standards and to avoid storing hot food in plastic containers for extended periods [2]. - The repeated use of plastic containers is not recommended, and the use of reusable, eco-friendly utensils is encouraged [2].
