Maize is widely cultivated throughout the world due to its high-yield potential. The economic and nutritional value of maize grains is associated with its starch content, protein, fibre, bioactive compounds, and minerals. Maize is used worldwide in the preparation of health-benefiting, antioxidant-rich, fortified products and dietary supplements.
Maize: Nutritional Composition, Processing, and Industrial Uses explores the status of maize in terms of its production, nutritional composition, biofortification, processing methods, health benefits, maize-based products, and storage. This book also emphasizes the key features of maize grains which make it an ideal crop for industrial use. It covers all aspects of recent research about the maize and provides updated information.
