Food science brings together food science and technology pdf scientific disciplines. Some of the subdisciplines of food science are described below.
Food physical chemistry is the study of both physical and chemical interactions in foods in terms of physical and chemical principles applied to food systems, as well as the application of physicochemical techniques and instrumentation for the study and analysis of foods. Food substitution refers to the replacement of fat, sugar, or calories from a product while maintaining similar shape, texture, color, or taste. Food technology is the technological aspects. Early scientific research into food technology concentrated on food preservation. Nicolas Appert’s development in 1810 of the canning process was a decisive event. The process wasn’t called canning then and Appert did not really know the principle on which his process worked, but canning has had a major impact on food preservation techniques.
Molecular gastronomy is a subdiscipline of food science that seeks to investigate the physical and chemical transformations of ingredients that occur in cooking. Its program includes three axis, as cooking was recognized to have three components, which are social, artistic and technical. New product development includes the invention of new food products. Quality control also ensures that product meets specs to ensure the customer receives what they expect from the packaging to the physical properties of the product itself. Sensory analysis is the study of how consumers’ senses perceive food. CSIRO maintains more than 50 sites across Australia and biological control research stations in France and Mexico. It has nearly 6,500 employees.
