Coconut milks are oil-in-water emulsions made of water, oil, carbohydrates, proteins, and ash. Surface active emulsifiers can improve their stability, while soy lecithin is a non-expensive and food-safe alternative. Enzyme-modified soy lecithin (ESL) has better water dispersion and higher HLB value, making it Generally Recognized As Safe (GRAS) and approved as a food additive.
