Glacial Acetic Acid Food Grade
Original price was: $ 2.29.$ 2.17Current price is: $ 2.17.
Glacial Acetic Acid Food Grade is a clear, colorless liquid organic compound with a pungent vinegar-like odor. It is a high-purity form of acetic acid specifically produced and processed for safe use in food applications. As the main component of vinegar (after dilution), it serves as a critical flavoring agent, pH adjuster, and preservative in the food industry. Food-grade acetic acid typically has a concentration of 80-100% (glacial acetic acid) or is diluted to lower concentrations (4-20%) for specific applications.
