Enzymes Production From Food Waste and Their Application

Abstract

The chapter reviews the fermentation-based production of industrially important enzymes from food waste (FW). Nearly one-third of the food produced globally is wasted and poses serious problems regarding its disposal. A number of dumping systems have been developed in the nations worldwide which has later become a threat to the environment. This problem is both of an environmental and economic concern. Recent developments in the area have revealed the application of bioremediation as the best way to dispose food waste. Composting and anaerobic digestion of the organic waste are gaining importance for the better use of household-level waste rather than just dumping it in landfill sites. This chapter focuses mainly on the different types of FW, its disposal techniques, optimization of the fermentation process for the production of different industrially valued enzymes like amylases, cellulases, pectinases, proteases, phytases, and a few others using a wide range of microorganisms from different types of food waste like kitchen waste and food processing waste.
