What is Glazing Agent INS 550?

Glazing Agent INS 550 is a food additive composed of sodium silicates, which are compounds made from the reaction of silica (sand) with sodium carbonate at high temperatures. It results in a glass-like, water-soluble structure often used in the food industry.

This compound is used primarily in the candy and confectionery sector to provide a glossy coating or finish, enhancing product appearance. While generally recognized as safe when used in regulated quantities, there is little to no direct research on its long-term health effects when consumed in food.

Seeing it on a label typically indicates a focus on the aesthetic appeal of the product, as it helps create an attractive, shiny surface particularly desirable in candies and similar items.

Commonly found in: Candy, Confectionery, Chewing gum

Research
