Toxicity: Low

What is L-Cystine and Cystine Hydrochlorides E921

The additive E921, also known as L-cysteine, is an amino acid used as a food additive in various processed products. L-cysteine is mainly obtained from pig hair, bird feathers or bacterial fermentation. This additive is used in the food industry for its functional properties, such as its ability to improve the texture of foods, increase dough stability, and accelerate the fermentation process. In addition, it acts as a reducing agent and flavor enhancer in baked products, breads, pizzas, cookies and meat products. Although L-cysteine is generally recognized as safe for human consumption in adequate amounts, some concerns have been raised about its origin in animal materials. However, most products labeled as vegetarian or vegan containing L-cysteine use a synthetic version or one derived from plant sources.
