E905 – Paraffins
Glazing agentDescription
Mixture of saturated hydrocarbons, obtained from petroleum
Notes
Microcrystalline wax is a petroleum-derived product made from the heavier components left over during oil refining. It starts as crude oil, which is processed in refineries to separate out different components – gasoline, diesel, and heavier fractions. The heavier waxes are further refined and purified to remove impurities, creating a mixture of saturated hydrocarbons (molecules made only of carbon and hydrogen atoms) that form a hard, stable wax. The "microcrystalline" name refers to its very small crystal structure, which makes it smoother and more flexible than regular paraffin wax. In food production, microcrystalline wax serves as a glazing agent, providing a protective, shiny coating that helps preserve freshness and improve appearance. You'll typically find it on fresh fruits and vegetables (like the glossy coating on some apples and cucumbers), some candies and confectionery items, and occasionally on cheese rinds. It creates a barrier that prevents moisture loss and gives products an attractive, uniform shine that consumers associate with freshness. This is a synthetic, petroleum-based additive that is suitable for vegetarians and vegans since it contains no animal products. It's considered safe for food use by regulatory agencies worldwide, including the FDA and European authorities, because it's highly refined and passes through the digestive system without being absorbed. The wax used in food applications is food-grade, meaning it meets strict purity standards and is different from industrial waxes. People following halal or kosher diets generally accept it since it doesn't contain any prohibited animal-derived ingredients.
