Research output: Contribution to journalArticlepeer-review


Potato peel is a by-product of potato food processing industries and can range from 15% to 40% of the initial product mass depending on the peeling methods. It is usually considered as a waste to be discarded. However, recent studies indicate that potato peel is potentially a valuable source of human dietary nutrients and could be converted into value-added products. The present review aims to summarize the characteristics of potato peel waste, including physicochemical composition, bioactivities and application possibilities in the food production industry. The main results show that potato peel waste can serve as a source for dietary fibers, antioxidants, and antibacterial food additives. These products will increase the value of potato peel waste and reduce extensive waste generation.
