5% Diluted Acetic Acid Food Grade

Product Overview

5% Diluted Acetic Acid is a clear, colorless liquid that is a diluted form of acetic acid (CH₃COOH). This food-grade solution is commonly used in culinary applications and food preservation due to its mild acidity and flavor-enhancing properties. The product is prepared to meet food-grade specifications, with tight control of assay, color, and impurities to ensure compatibility with food contact environments. Its low odor profile relative to concentrated acid and complete aqueous solubility make it suitable for uniform distribution in liquid formulations and marinades. ANSI/ASTM-aligned quality controls, including titration-based assay verification and multi-element impurity screening, support consistent performance in batch production.

Its management within standard food-processing workflows enables reliable pH adjustment, preservative action, and flavor modulation without introducing offensive sensory characteristics. The solution can be integrated into pickling, dressing formulations, and beverage adjuncts where a mild acidity is desired. With a 5% w/w concentration, processors gain predictable acidity, improved handling, and reduced risk of over-acidification when scaling from pilot to production runs. Regular quality checks and adherence to storage guidance help preserve product integrity across shipments and storage conditions.

Safety Precautions

Handle with appropriate PPE including chemical-resistant gloves and safety goggles. Store in a cool, dry place away from direct sunlight in containers made of HDPE or glass. Ensure adequate ventilation during handling to minimize inhalation exposure, and keep containers tightly closed when not in use. Do not mix with bases or strong oxidizers, which can react and release heat or vapors. Use proper containment in case of spills and follow standard operating procedures for corrosives in food-contact environments.

Routinely verify compatibility with processing equipment and food-contact surfaces. Follow storage and handling instructions per the SDS, including use of fume hoods or local exhaust as needed. Maintain separation from incompatible materials, and observe labeling and segregation practices to prevent cross-contamination. In case of skin or eye contact, rinse thoroughly with water and seek medical attention if irritation persists.
