 Food science is the applied science devoted to the study of food. The Institute of Food Technologists defines food science as the discipline in which the engineering, biological, and physical sciences are used to study the nature of foods, the causes of deterioration, the principles underlying food processing, and the improvement of foods for the consuming public. In the textbook Food Science defines food science in simpler terms as the application of basic sciences and engineering to study the physical, chemical, and biochemical nature of foods and the principles of food processing. Activities of food scientists include the development of new food products, design of processes to produce these foods, choice of packaging materials, shelf life studies, sensory evaluation of products using survey panels or potential consumers, as well as microbiological and chemical texting. Food scientists may study more fundamental phenomena that are directly linked to the production of food products and its properties. Food science brings together multiple scientific disciplines. Food Inc. incorporates concepts from fields such as microbiology, chemical engineering, and biochemistry.
