Abstract

Juglans regia shells are considered one of the non-edible parts of the dry fruit, thereby resulting in the addition of shell waste, causing a rise in ecological problems based on waste management. In the fruit and vegetable products industries, a lot of waste occurs during every step of production; when selecting, sorting, and boiling processes are done, tons of dry and wet waste is generated. The non-edible parts of the plants that are discarded are often not known for their bioactive components. The unexplored bioactive activities of the shells and the focus on exploring the possible dietary and therapeutic potentials of such underutilized wastes will reduce the possible environmental waste burden. The objectives of this research were to alert the functionality, chemical composition, and biological properties of Juglans regia shells for their use as food and justification for its medicinal use. In this comprehensive research, the bioactive components in Juglans regia shells were identified, and the total phenolic content, mineral content, flavonoid content, and antioxidant activity were studied as a potential bioresource for the extraction of nutraceuticals and bioactive compounds. Further, their efficient utilization in the development of nutraceutical products, their health benefits, and the value addition of food waste resources have also been discussed for possible dietary and therapeutic potentials of especially underutilized agro-food waste to aid in reducing the possible environmental waste burden.
