What is L-Cysteine Hydrochloride?
L-Cysteine Hydrochloride is the hydrochloride salt form of L-Cysteine, an amino acid containing sulfur. It is more stable, water-soluble, and faster absorbed than L-Cysteine in its base form. L-Cysteine HCl is used extensively in the food industry as a dough conditioner (E920), particularly in bakery products to enhance gluten extensibility, reduce mixing time, and improve overall texture.
In nutraceuticals and pharmaceuticals, it serves as a precursor to glutathione, the body’s key antioxidant. It also has applications in flavor creation through the Maillard reaction (especially savory/meaty flavors), and in cosmetic and hair care formulations for its antioxidant and restorative properties.
Our L-Cysteine Hydrochloride is produced via non-GMO microbial fermentation, making it vegan, halal, and kosher compliant.
