👉 Saponify is a chemical process used in food preservation to make ingredients water-soluble. This involves making a fat-based oil (saponification) and then converting it into a liquid state by adding an acid or base, such as sodium hydroxide or potassium hydroxide, which reacts with the fatty acids in the saponified mixture. Saponification is often used to make dairy products like butter or cream from milk, but it can also be applied to other foods like eggs
