In this article, we discuss carbon nanoparticles for application as antibacterials and food-packaging materials. The use of petroleum-derived products, synthetic materials, ceramics, wax, etc. in the food-packaging industry emits polluted gas and wastewater, which leads to environmental pollution. To overcome the problems faced by the industry to preserve and package food, carbon nanomaterials may be good alternatives to enhance the shelf life of food without affecting the nutrients. Carbon atoms bond with each other in diverse ways to form many allotropes, resulting in a variety of carbon nanomaterials (CNMs). CNMs include zero-dimensional carbon dots, graphene quantum dots, 1-dimensional carbon nanotubes, 2-dimensional pristine graphene, graphene oxide, reduced graphene oxide, and other derivatives of graphene. Most of the carbon-based nanomaterials are synthesized through a green process that is widely used in the field of food science and technology, and they are used mostly as antibacterial agents and as a biofiller in the development of active food-packaging materials. Carbon nanomaterials (CNMs), viz., carbon dots, graphene, activated carbon-based nanocomposites, carbon nanotubes, etc., are found to be environmentally benign and better materials for food packaging. With antibacterial efficiency, they support food preservation and other applications as well. Thus, carbon nanostructures are found to be applicable as superior materials for food preservation and packaging in modern industry.
在本文中，我们讨论了用作抗菌剂和食品包装材料的碳纳米颗粒。食品包装行业中使用石油衍生产品、合成材料、陶瓷、蜡等会排放污染气体和废水，从而导致环境污染。为克服该行业在食品保存和包装方面面临的问题，碳纳米材料可能是在不影响营养成分的情况下延长食品保质期的良好替代品。碳原子以多种方式相互结合形成许多同素异形体，从而产生了多种碳纳米材料（CNM）。碳纳米材料包括零维碳点、石墨烯量子点、一维碳纳米管、二维原始石墨烯、氧化石墨烯、还原氧化石墨烯以及石墨烯的其他衍生物。大多数碳基纳米材料是通过绿色工艺合成的，该工艺在食品科学与技术领域广泛应用，并且它们大多用作抗菌剂以及活性食品包装材料开发中的生物填料。碳纳米材料（CNM），即碳点、石墨烯、活性炭基纳米复合材料、碳纳米管等，被发现对环境无害，是用于食品包装的更好材料。凭借抗菌效率，它们还支持食品保存及其他应用。因此，碳纳米结构被发现是现代工业中用于食品保存和包装的优质材料。
