Polyphenol oxidase (PPO) is an enzyme responsible for enzymatic browning. This enzyme oxidises polyphenols found in fruits and vegetables, resulting in the formation of brown pigments. Controlling the activity of PPO is important to extend the shelf life of foods and prevent discolouration. Carbon quantum dot (QD) has become an important area of interest in nanotechnology in recent years. Carbon quantum dots are carbon-based nanomaterials, 0-10 nm in size, which have a wide range of potential applications. The biological activities of carbon quantum dots have been demonstrated in many studies such as antioxidant and antimicrobial properties. In this study, it was aimed to synthesis carbon quantum dots from hazelnut membrane by microwave synthesis method in an environment containing formic acid and acetic acid and to investigate their in vitro effects on PPO enzyme. It was investigated whether carbon quantum dots can inhibit PPO activity.
