Abstract
Abstract Increase in life style related diseases and occurrence of pandemic made consumers highly aware of the close association of nutrition with health. Agro industrial processing, a sunrise sector focuses on effective utilisation of plant produce by adding value. Processing generates large quantity of waste which is usually rich in protein, starch and other bioactive constituents. Proper exploitation of these agro‐processing by‐products has significant socio‐economical as well as environmental benefit by generating income out of waste material and reducing environmental pollution. Extraction of protein from these wastes helps in creating diversified options for plant‐based proteins particularly for those individuals who are allergic to soya or dairy protein. This review gives a brief insight into possibility of exploiting the processing waste as protein sources and its potentiality for diversified food applications. The proteins extracted from the processing of by‐products may help to address few emerging socio‐economic challenges, including chronic hunger, nutritional deficiency and food security, along with meeting the sustainable development goals through effective waste utilisation and minimising environmental pollution.
