摘　　要：碳点(carbon dots,CDs)作为新兴的纳米颗粒,由于其优越的生物相容性和光致发光性,被广泛应用于化学传感、生物成像、药物递送、光催化剂和食品检测等领域。食品加工副产物来源广泛,容易获得,且其制备的CDs表面通常含有丰富的官能团与杂元素,这一特点赋予了CDs更优异的光催化、抗氧化和抗菌特性。近年来,CDs被作为食品包装添加物以增强食品包装紫外屏蔽、机械强度、抗氧化和抗菌等性能。本文综述了可用于制备CDs的食品加工副产物种类和添加CDs的天然聚合物基薄膜,以及CDs在活性和智能包装中的应用,以期为食品加工副产物源CDs的制备及其在食品包装中的应用提供参考。As an emerging nanoparticle,carbon dots(CDs)have been widely used in the fields of chemical sensing,biological imaging,drug delivery,photocatalyst and food detection due to its superior biocompatibility and photoluminescence.Food processing by-products come from a wide range of sources and are easy to obtain.Moreover,the surface of CDs prepared from food processing by-products is usually rich in functional groups and miscellaneous elements,imparting excellent photocatalytic,antioxidant and antibacterial properties to CDs.In recent years,CDs have been used as food packaging additives to enhance the ultraviolet(UV)shielding,mechanical,antioxidant and antibacterial properties of food packaging.In this paper,the types of food processing by-products that can be used to prepare CDs and natural polymerbased films added with CDs and the application of CDs in active and intelligent packaging are reviewed in order to provide guidance for the preparation of CDs from food processing by-products and its application in food packaging.
