Food-grade diatomaceous earth is a fine powder made from the fossilized remains of microscopic aquatic organisms known as diatoms. These organisms belong to a group of algae with intricate silica-based shells. Over millions of years, their remains accumulated in sediment layers, eventually forming mineral deposits that can be mined and processed.

When diatomaceous earth is ground into powder, it has a light texture and pale color. Under a microscope, the particles reveal intricate shapes corresponding to the shells of ancient diatoms. These shells are composed largely of silica, which contributes to the material’s unique physical properties.

Food-grade diatomaceous earth differs from industrial forms of the material in terms of processing and purity standards. It is refined to reduce certain impurities and is intended for specific uses related to food handling or storage.

One of its traditional uses involves grain storage. The powder may be applied to stored grains to help…
