Food engineering is a comprehensive food technology field involving the various disciplines of food science, agriculture, microbiology, chemistry, and engineering. Using carefull research methods, high-tech equipment and sophisticated processes, food process engineering covers the entire gamut from procuring raw food materials to processing them into food products to preserving, packaging an delivering the food products to the consumer market. Producing safe and nutritious food for human and animal consumption is one of the principal aims of food engineering. High-quality raw materilas are handled and processed by special, computerized equipment in food processing plants.
