ABSTRACT
Agri-food waste is a by-product or waste generated from various agriculture processes, post-harvest, and production and processing of different food products in the food industry, restaurants, and households. These by-products or wastes are mostly plant or animal based. Improper disposal of these can lead to harmful effects on the environment. However, they are rich in valuable compounds that exhibit various health-promoting properties. Thus, utilization of these by-products or wastes to recover nutraceuticals is of great interest for multiple industries. Enzymes are highly valued in various industries due to their high yield, specificity, minimal by-product formation, ease of the process, etc. Many microbial enzymes from bacteria and yeast sources have been explored for their importance in recovering nutraceuticals from various sources in a cost-effective and nature-friendly manner. Research in this area has contributed significantly to developing advanced bioprocess methods, particularly to valorize agro-food industry waste to obtain novel functional compounds exhibiting health-promoting properties.
