E473, or sugar esters of fatty acids, is often used in the food industry as a food additive.
This ingredient has emulsifying properties, allowing it to mix water and fat to create a uniform texture in the product.
Sugar esters of fatty acids can be found in various products such as dairy, desserts, snacks, confectionery, and other ready-to-eat foods.
Overall, E473 is not considered a harmful component, but for strict followers of the keto diet, it is advisable to be cautious of its presence in products.
