E479 – Thermally oxidized soya bean oil interacted with monoand diglycerides of fatty acids
EmulsifierDescription
Mixture of glycerol esters of fatty acids and thermally oxidized soybean oil
Notes
E479 is made by heating soybean oil at high temperatures in the presence of oxygen, then combining it with glycerol (a sweet, syrupy substance also found in soap and cosmetics). This thermal oxidation process changes the oil's chemical structure, creating new compounds that have useful properties for food manufacturing. The resulting ingredient is a complex mixture that looks like a thick, amber-colored oil. This additive works as an emulsifier, which means it helps ingredients that normally don't mix well (like oil and water) stay blended together smoothly. You'll commonly find E479 in baked goods like bread and pastries, margarine, and some processed foods where maintaining a consistent texture is important. It helps create that smooth, even consistency and prevents separation that would otherwise make products look or feel unappetizing. Since it's derived from soybeans, E479 is suitable for vegetarian and vegan diets, though people with soy allergies should be cautious. The thermal oxidation process creates some artificial compounds not found in nature, so while it starts with a natural ingredient (soybean oil), the final product is considered a processed additive. It's approved for use in many countries, though some manufacturers are moving toward simpler alternatives due to consumer preference for less processed ingredients.
