Abstract:

India is a leading producer, processor, and consumer of potatoes. India generates approximately 2 million metric tonnes of potato processing waste and approximately three times as much on-farm waste annually. These wastes are either dumped or utilized to produce biofertilizers and biofuels. However, the untapped nutritional eminence of the substrate wasted in this utilization model, holds greater prospects. If cultivated in a biorefinery model for extracting high-value nutrients such as phenolics, starch, and protein, these potato wastes can generate a multi-million-dollar industry in India. The stated strategy ensures the successful implication of SDG Goal 12, which focuses on ensuring sustainable consumption and production patterns. Literature on utilizing potato waste is widely available; however, focus on Indian varieties is scarce. The available valorization models are predominantly based on bioenergy, and an evident gap lies in the substrate's nutritional scope. Among the nutritional extractives, dietary choline is found to be the most valuable emerging high-value compound. However, no literature on the extraction or quantification of dietary choline in the substrate of interest is available. Hence, this research project aims to primarily explore the presence of dietary choline in potato waste and design a biorefinery for the simultaneous extraction of valuable nutrients from Indian varieties. The proposed research will traverse green extraction pathways for the targeted nutritional compounds and develop a techno-economically feasible valorization model for potato farming and processing communities.
