Extraction of protein and polyphenols from agro-industrial waste through eco-innovative technologies

The recovery of valuable sources from waste material is an excellent and encouraging approach towards the ecological significances and food security. Agro-industrial surplus produced by agricultural and food processing activities signifies a rich source of beneficial compounds like minerals, vitamins, and other essential components that are helpful in different industries for different purposes. The demands of plant-based protein extraction are very high. Along with proteins, various bioactive components, like carotenoids, lycopene, polyphenols, sugars, and polysaccharide, have also been extracted with the help of eco-friendly technologies. The purpose of this chapter is to study the latest researches related to extraction of protein and polyphenols or also to highlight the significances of green-technologies. These eco-friendly technologies play their vital role in producing nutrient rich products from waste residues to overcome the food shortage and to maintain food wastage.
