This volume takes an eco-friendly approach to examining the advantages of using plant food by-products as food additives and nutraceuticals, turning solid wastes into value-added items. The chapters, written by researchers and professionals working in the plant food industry, look at ways to make effective use of plant by-products by harnessing the power of the antimicrobial and nutraceutical power of plant and herb extracts. The measures and techniques discussed here will also help to improve the economics of processing crops. The chapter authors cover a range of issues, including the economic and environmental benefits of utilizing plant food by-products, extraction technologies, plant tissues as a source of nutraceutical compounds, and more.
