What is Mono- and Diglycerides of Fatty Acids?

Mono and diglycerides of fatty acids are emulsifiers made from glycerol and fatty acids derived from plant or animal sources. They help blend ingredients that typically don't mix well, like oil and water.

These compounds stabilize mixtures and improve texture in various foods and beverages. While generally recognized as safe (GRAS) by the FDA, there is some concern about their potential origin from partially hydrogenated oils, possibly containing trans fats.

When you see mono and diglycerides on a label, it might indicate a role in maintaining consistency, especially in baked goods and spreads.

Commonly found in: baked goods, margarine, ice cream, salad dressings, peanut butter, coffee creamers

What to watch

May contain traces of trans fats depending on the source of fatty acids.
Potentially sourced from animal products, impacting suitability for vegans.

Scout's take

Mono- and diglycerides are emulsifiers used to improve texture and stability in processed foods. They are derived from fats but are highly processed. Their consumption is generally considered safe but adds to the processed nature of foods.
