Food-Grade Acetic Acid CAS#64-19-7
Food-Grade Acetic Acid CAS#64-19-7 High Solubility: Food-grade acetic acid demonstrates excellent solubility in water and is readily soluble in organic solvents such as ethanol, ether, and acetone, facilitating its extensive employment in food processing, pharmaceutical production, and daily chemical industries.
Stable pH: The dilute aqueous solution of this compound maintains stable acidic pH under conventional heating and long-term storage conditions, showing reliable chemical and thermal stability in food-grade application environments.
Versatile Uses: It serves as a food acidity regulator, flavoring agent, and preservative in the food industry, an intermediate in fine chemical synthesis, and a cleaning and bacteriostatic agent for daily product processing.
Liquid Form & Mild Irritant Nature: This material is provided as a colorless transparent liquid with a characteristic sour odor, featuring high purity and low impurity content that meets food safety standards, making it applicable in food production scenarios that require safe formulation and standardized handling.
Food-grade acetic acid, characterized by the molecular formula C₂H₄O₂, presents as a colorless, clear liquid with a typical pungent sour taste and odor. It exhibits infinite miscibility with water, ethanol, and glycerin at 25°C, while displaying limited solubility in non-polar solvents including benzene and carbon tetrachloride. Its dilute aqueous solution maintains stable acidic properties and does not undergo decomposition or deterioration under normal heating conditions. The substance adopts high-purity food-grade purification standards with low corrosivity compared with industrial acetic acid and is utilized as a core food additive, organic synthetic raw material, and mild acidic treatment agent in food, beverage, pharmaceutical and cosmetic industries.
