Food science is called an integrated course because it makes use of several principles of biology, chemistry, and other related sciences. In other words, it is the study of the physical, biological, and chemical makeup of food; and the concepts underlying food processing. Food technology is the application of food science to the selection, preservation, processing, packaging, distribution, and use of safe food.
Food scientists and technologists apply scientific disciplines including chemistry, engineering, microbiology, and nutrition to the study of food to improve the safety, nutrition, wholesomeness and availability of food. Depending on their area of specialization, food scientists may develop ways to process, preserve, package, and/or store food according to industry and government specifications and regulations.
