Food Grade refers to materials, additives, or chemicals that are safe for human consumption and meet stringent purity and safety standards set by food regulatory authorities such as the U.S. Food and Drug Administration (FDA), European Food Safety Authority (EFSA), or Codex Alimentarius. These substances are specifically approved for use in food production, processing, packaging, or preparation, ensuring they do not pose health risks when ingested.  Food-grade materials must be free from harmful contaminants, such as heavy metals, toxic residues, or pathogenic microorganisms, and they often comply with specifications like Food Chemical Codex (FCC) for purity. Examples include preservatives, flavorings, colorants, emulsifiers, and packaging materials (e.g., food-safe plastics or lubricants for machinery). 

Titanium Dioxide

Titanium Dioxide (TiO₂) is a naturally occurring oxide of titanium known for its exceptional brightness and high refractive index. It is one of the most widely used white pigments in the world due to its excellent opacity, UV resistance, and chemical stability. Available in various crystalline forms—mainly rutile and anatase—it is used across numerous industries including paints, plastics, paper, cosmetics, and food. Industrial grades are often surface-treated to enhance performance in specific applications.
