Yeast Extract, identified by CAS number 8013-01-2, is a complex mixture of water-soluble components derived from the autolysis of yeast cells, typically strains of Saccharomyces cerevisiae. This material is highly valued for its rich concentration of amino acids, peptides, vitamins, and minerals, which are released when the yeast cell walls are broken down. Physically, it often appears as a fine, yellowish-to-brown powder or a viscous paste, characterized by a distinct savory aroma and high solubility in aqueous solutions.
In industrial and laboratory settings, Yeast Extract serves as a versatile nutrient source. Due to its hygroscopic nature, it requires careful handling and storage in tightly sealed containers to prevent moisture absorption and clumping. Its chemical stability under standard conditions makes it a reliable raw material for various formulations, providing essential growth factors that are difficult to synthesize artificially. Its role as a natural, nutrient-dense additive makes it indispensable across multiple scientific and manufacturing sectors.
