General description
Malt extract is the water-soluble portion of malted barley. It contains a high content of reduced sugars and to a lesser extent nitrogenous constituents. The carbohydrates comprise mainly the disaccharide maltose and fractions of hexoses such as glucose and fructose, the disaccharide sucrose and other carbohydrates. The nitrogenous components include peptides, amino acids purines and vitamins. Malt extract favors the sporulation of molds such as Aspergillus and Penicillium and so can be used for the industrial fermentation but also in the preparation of microbiological culture media. The malt extract is not of animal origin.
Application
Malt Extract is used as a nutritive substrate in mycological media for the propagation of yeasts and molds and test strains in vitamin assays.
