Food-grade divider oils prevent food from sticking by creating a non-stick barrier between the food and the cooking surface. These oils are typically composed of a blend of vegetable oils, emulsifiers, and sometimes lecithin, which is a natural phospholipid. When applied to baking trays, pans, or molds, the oil forms a thin, even coating that reduces the surface tension between the food and the cooking surface.
The primary mechanism by which divider oils work is through lubrication. The oil fills in the microscopic crevices and irregularities on the surface of the cookware, creating a smooth layer that minimizes direct contact between the food and the surface. This reduces the adhesion forces that would otherwise cause the food to stick.
Additionally, the emulsifiers in the oil help to stabilize the oil layer, ensuring it remains evenly distributed and effective throughout the cooking process. Emulsifiers can also help the oil to spread more uniformly, enhancing its non-stick properties.
In baking, divider oils are particularly useful for preventing doughs and batters from adhering to pans, allowing for easy release and maintaining the integrity and appearance of the final product. They are also used in industrial food production to facilitate the easy removal of baked goods from molds and conveyors, improving efficiency and reducing waste.
Overall, food-grade divider oils are an essential tool in both home and commercial kitchens, providing a simple and effective solution to the common problem of food sticking during cooking and baking.
