What it is

L-cysteine is an amino acid, a building block for proteins. It can be sourced from animal products, like feathers or hair, or produced synthetically. Soy lecithin is a fat derived from soybeans, often used as an emulsifier.

Why it's used

L-cysteine is often used as a dough conditioner to improve the texture and workability of baked goods, especially bread and pizza dough. Soy lecithin is used as an emulsifier, helping to blend ingredients that don't normally mix, like oil and water, and also acts as a stabilizer.

Health notes

L-cysteine is generally recognized as safe (GRAS) by the FDA for use in food. It is also approved as a food additive in the EU. JECFA has evaluated L-cysteine and set an acceptable daily intake. Soy lecithin is also GRAS. Both are common food components, and at typical dietary levels, they are not associated with adverse health effects.

Allergen info

Soy lecithin is derived from soy, which is one of the 9 FDA major allergens. L-cysteine itself is not a major allergen. Gluten is not present.
