Lactate dehydrogenase (LDH or LD) is an enzyme found in nearly all living cells. LDH catalyzes the conversion of pyruvate to lactate and back, as it converts NAD + to NADH and back. A dehydrogenase is an enzyme that transfers a hydride from one molecule to another. LDH exists in four distinct enzyme classes.
Because food science is a multi-disciplinary field, food physical chemistry is being developed through interactions with other areas of food chemistry and food science, such as food analytical chemistry, food process engineering/food processing, food and bioprocess technology, food extrusion, food quality control, food packaging, food ...
In some cases, the pH value of the solution used during the synthesis and the high drying temperature of the LDH can eliminate the presence of the OH − groups in the LDH. For example, in the synthesis of the (BiO) 4 (OH) 2 CO 3 compound, a low pH value of the aqueous solution or higher annealing temperature of the solid can induce the ...
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.
Food technology is a branch of food science that addresses the production, preservation, quality control and research and development of food products. It may also be understood as the science of ensuring that a society is food secure and has access to safe food that meets quality standards.
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.
As a food additive it is approved for use in the EU, [48] United States [49] and Australia and New Zealand; [50] it is listed by its INS number 270 or as E number E270. Lactic acid is used as a food preservative, curing agent, and flavoring agent. [51] It is an ingredient in processed foods and is used as a decontaminant during meat processing ...
