What is L-Cysteine?

L-Cysteine is a naturally occurring amino acid that is commonly used in the food industry as a dough conditioner to improve the texture and elasticity of baked goods. Although it can be synthesized, it is most often sourced from animal products such as hair and feathers, making it unsuitable for vegans. In some cases, it may also be derived from non-animal sources like coal tar, but this is less common.
