The fifth scientifically recognised taste sensation alongside bitter, salty, sour and sweet. It is perceived through the presence of glutamate in food or drinks. Glutamate is the sodium salt of the amino acid glutamine. Amino acids are the basic building blocks for proteins. The substance develops flavour-enhancing properties in food and plays a special role in the palatability and acceptance of many foods. Glutamate (glutamic acid) is found as a building block in almost all proteins and is consumed with almost every meal. Vegetable proteins can even contain up to 40 % glutamic acid. However, glutamate should not be confused with gluten (gluten protein), to which some people have an allergic reaction.
Using the encyclopaedia is not only time-saving, but also extremely convenient. What's more, the information is always up to date.
