Succistearin
Also known as: E446
Succinylated monoglycerides are an FDA-permitted food emulsifier used at low levels (typically <0.5%). Evidence-based safety reviews indicate good emulsion-stabilizing performance with no significant toxicity at food-use levels.
What it is
Succistearin (succinylated monoglycerides) is a food-grade emulsifier produced by reacting monoglycerides with succinic anhydride.
Emulsifier and dough conditioner; stabilizes oil-in-water emulsions and improves bread volume and crumb structure.
Why it's flagged
- Generic processed-food additive; presence may indicate ultra-processed product
What regulators actually say
"succinylated monoglyceride (SMG) is a food-grade emulsifier that demonstrates superior performance in stabilizing complex emulsions ... the SMG-stabilized emulsion exhibited the highest emulsifying activity and the lowest viscosity value and possessed the highest stability over 14 days."
