Springer® 4000 yeast extracts
Flavor: characteristic
The Springer® 4000 yeast extracts provide Kokumi taste, or mouthfullness, thanks to the naturally occurring sulfur amino acids and peptides they contain. They provide intense poultry stock flavour and enhance meat and cheese flavours. These glutathione-rich extracts work well on their own or in synergy with one of our Springer® yeast extracts.

L-Glutathione is a small protein consisting of three amino acids: cysteine, glutamic acid and glycine. It neutralizes free radicals that can cause cellular damage. It also acts as a regulator for other antioxidants in the body, such as Vitamins C & E, and is found in every cell in the body. It plays an important role in cellular metabolism, immunity and overall health and wellness.

a tripeptide with many roles in cells. it conjugates to drugs to make them more soluble for excretion, is a cofactor for some enzymes, is involved in protein disulfide bond rearrangement and reduces peroxides. Glutathione (GSH) - reduced glutathione - is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. [Wikipedia]
