Food physical chemistry concepts are often drawn from rheology, theories of transport phenomena, physical and chemical thermodynamics, chemical bonds and interaction forces, quantum mechanics and reaction kinetics, biopolymer science, colloidal interactions, nucleation, glass transitions, and freezing, [8] [9] disordered/noncrystalline solids.
Gastrophysics is a scientific discipline that focuses on investigations of aspects of gastronomy and cooking that relates to phenomena, which can be described and explained in a frame of physics, physical chemistry, chemistry, and associated sciences.
The scientific approach to food and nutrition arose with attention to agricultural chemistry in the works of J. G. Wallerius, Humphry Davy, and others.For example, Davy published Elements of Agricultural Chemistry, in a Course of Lectures for the Board of Agriculture (1813) in the United Kingdom which would serve as a foundation for the profession worldwide, going into a fifth edition.
Water-in-oil emulsions are less common in food, but still exist: Butter – an emulsion of water in butterfat; Margarine; Other foods can be turned into products similar to emulsions, for example meat emulsion is a suspension of meat in liquid that is similar to true emulsions.
Food scientists working in Australia A food science laboratory. Food science (or bromatology [1]) is the basic science and applied science of food; its scope starts at overlap with agricultural science and nutritional science and leads through the scientific aspects of food safety and food processing, informing the development of food technology.
Water is found in many foods and has been defined as a food by itself. [6] Water and fiber have low energy densities, or calories , while fat is the most energy-dense component. [ 3 ] Some inorganic (non-food) elements are also essential for plant and animal functioning.
Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacteria growth. Freezing is a widely used method of food preservation. Freezing generally preserves flavours, smell and nutritional ...
Food energy is chemical energy that animals (including humans) derive from their food to sustain their metabolism, including their muscular activity. [ 1 ] Most animals derive most of their energy from aerobic respiration , namely combining the carbohydrates , fats , and proteins with oxygen from air or dissolved in water . [ 2 ]
