One of the most significant fruit crops in the world is citrus. Citrus L. is its scientific name, and it belongs to the Rutaceae family. In addition to many other regions, it is widely grown in tropical and subtropical regions, which collectively generate about 100 million tons per year (Gonzatto and Santos 2023). The most often grown crops are citrus fruits. Important oils that might be utilized in food and other industrial processes may be found in citrus species. Citrus fruits are regarded as nutrient-dense, energy-dense, and health-promoting fruits all over the world. Asian nations have long utilized a number of these fruits—lemon, grapefruit, sweet orange, citron, clementine, and pomelo as traditional medical herbs to treat a wide range of ailments. Citrus fruits were shown to have bioactive chemicals and secondary metabolites that can be employed as supplements or as chemotherapeutics in a number of investigations. The citrus fruits that are most often grown worldwide include oranges, lemons, grapefruits, mandarins, and limes. Citrus processing companies generate a lot of garbage each year; the waste from citrus peels alone accounts for over half of the wet fruit mass. Ingredients that are beneficial for human consumption but are deteriorated, contaminated, and thrown away make up food waste. A growing problem that impacts every aspect of waste management is food waste (Maqbool et al. 2023).
