Yeast extract, with the CAS number 8013-01-2, is a complex mixture derived from the cellular components of yeast, primarily Saccharomyces cerevisiae. It is rich in proteins, amino acids, vitamins, and minerals, making it a valuable nutrient source in various applications, particularly in the food and biotechnology industries. Yeast extract is often used as a flavor enhancer due to its umami taste, which is attributed to the presence of nucleotides and peptides. It is also utilized in microbiological media as a growth supplement for bacteria and fungi. The extract is typically produced through the autolysis of yeast cells, where enzymes break down cell walls, releasing intracellular components. Yeast extract is generally recognized as safe (GRAS) for consumption and is available in various forms, including powder and paste. Its solubility in water and stability under various conditions make it versatile for use in soups, sauces, and processed foods, as well as in laboratory settings for culturing microorganisms.

Yeast Extract

Yeast extract powder is a substance that is used in experimental models to study the effects of chemicals on yeast cells. Yeast extract powder can be made by adding potassium dichromate and sodium citrate to a reaction solution, which causes cell lysis. Yeast extract powder can also be made by adding nutrient solution to a bacterial strain, such as Escherichia coli. Yeast extract powder can also be made by adding monoclonal antibodies or particles, such as polystyrene beads, to a wild-type strain of Saccharomyces cerevisiae (Pichia pastoris). Yeast extract powder has been shown to have protease activity when reacting with surface methodology.
