Document Summary
Food science 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, packaging, distribution and use of safe food. Utilizes many disciplines: molecular biology, genetic engineering, biochemistry, microbiology, biochemical engineering, food science, oenology, waste treatment, etc. Experimented with preserving foods by placing them in glass jars, sealing and placing them in boiling water. Published his method in 1810, before it was understood that heat kills bacteria. Demonstrated that fermentation is caused by the growth of micro-organisms (yeast) Made many discoveries that laid an important foundation for food science and. Germ theory of disease states that some diseases are caused by microorganisms. Pasteurization = heating foods just enough to kill most of the bacteria that caused spoilage. Much of food technology is driven by the military. Nicholas appert won the prize 15 years later.
