AjiPure™ Cysteine
Flavor: characteristic
Manufactured under cGMP conditions using no materials of animal origin.
Ajinomoto USA
Flavor: characteristic
L-cysteine is recognized as a conditionally essential amino acid. Under normal physiologic conditions, the body can produce sufficient levels of L-cysteine. However, preterm infants cannot synthesize L-cysteine in the body; therefore it must be obtained via the diet.

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. Because they are naturally rich in sulfur amino acids, Springer® 4000 yeast extracts eliminate the need for adding individual sulfur amino acids during flavour production.
