Guanosine monophosphate ( GMP) is a nucleotide, the phosphoric acid ester of the nucleoside guanosine. It forms together with adenosine monophosphate ( AMP), cytidine monophosphate (CMP) and uridine monophosphate (UMP ), the basic building blocks of the ribonucleic acid ( RNA).
Natural occurrence, significance, extraction
As part of the RNA GMP is present in all living things. The RNA used in cells for the conversion of genetic information from deoxyribonucleic acid ( DNA) into proteins. It is industrially produced generally by means of microorganisms, which can also be genetically modified.
Use
Guanosine monophosphate / kg for all food additives approved for use is approved in the EU as a food additive with the E number 626 up to a maximum amount of 500 mg. It is - as well as the disodium (E 627 ), dipotassium (E 628 ) and calcium salt (E 629) - used as a taste enhancer, wherein the compounds show a 10 to 20 times more potent than glutamic acid ( glutamate ). In addition small quantities of the flavor of many foods is amplified (especially finished products and canned food ) and off some unwanted flavors. In conjunction with glutamate GMP and its salts act synergistically to increase even at low levels, such as 1:10, the taste-enhancing effect.
Dikaliumguanylat and Calciumguanylat be used as a sodium- free salt substitute.
