Cereals, legumes, oilseeds, fruits, and vegetables are the most important food crops in the world, with cereal grains contributing the bulk of food calories and proteins worldwide. Generally, the supply of grains and other food can be enhanced by increasing production and by reducing postharvest losses. While food production has increased significantly over the last few decades, minimizing huge postharvest losses as well as utilizing their by-products/wastes is the optimal way for a country to become self-sufficient in food. Postharvest Technology and Food Process Engineering combines these two subject areas as it covers both the primary processing of cereals, pulses, fruits, and vegetables and utilization of by-products/biomass.
This book covers postharvest food preservation and processing methods, with an emphasis on grains. It is divided into five parts:
Grain-Properties, Drying and Dryers
Grain Storage
Parboiling and Milling
By-Products/Biomass Utilization
Food Process Engineering
The text covers grain structure and composition, psychrometry, the theory and methods of grain drying, and desig, testing, specification, and selection of grain dryers. It describes processes such as parboiling, of grain, hydrothermal treatment of grain, and milling of rice and other grains and pulses. The text also addresses biomass utilization and conversion technologies for energy, chemicals, food, and feed. The final section on food process engineering examines powtharvest management including cooling and packaging, and discusses preservation and processing, factors that affect deterioration, and various industrial preservation methods of fruits and vegetables. It also provides an overview of food chemistry and covers food engineering operations, including fluid mechanics and heat transfer.
