E477 Propylene glycol mono- and di-esters or Propylene glycol esters of fatty acids

What is E477 or Propylene glycol esters of fatty acids?

E477 refers to propylene glycol esters of fatty acids, a class of emulsifiers used in processed foods to stabilize fat and water mixtures. These esters are made by combining propylene glycol with fatty acids sourced from vegetable oils or animal fats. Commonly used in baked goods, desserts, and dairy products, E477 helps improve texture and shelf stability.

Why do I have an intolerance?

Intolerance to E477 may arise if your body reacts negatively to propylene glycol, a synthetic compound that some people find difficult to metabolize. This intolerance can manifest as nausea, bloating, or diarrhea. Additionally, sensitivity to the fatty acid components or their animal origins might contribute to digestive issues or allergic reactions.

What can I do about it?

If you suspect intolerance to E477, it's advisable to avoid processed foods, especially baked goods and desserts, that list this additive. Switching to homemade or simpler food products can help you avoid propylene glycol and its derivatives. Be sure to check ingredient lists carefully and opt for products made with natural emulsifiers or without additives.
