Acetic Acid Glacial - Food Grade

Product Overview

Acetic Acid Glacial - Food Grade is a colorless, volatile liquid with a pungent odor, primarily composed of acetic acid (CH₃COOH) at a high purity of ~99.7%. This product is manufactured to meet stringent food-grade specifications, suitable for direct use in food preservation, flavoring, and acidity regulation. The typical assay range (99–100.5 wt%) is verified by titration with standardized NaOH, ensuring consistent acidity for process control in batch manufacturing. Its low impurity profile is confirmed by trace metals and inorganic ion analyses, aligning with HACCP-based quality programs and USP/ACS expectations for food-grade acetic acid.

The material demonstrates favorable physicochemical properties that support scalable production environments: a density of 1.049 g/mL at 25°C, a boiling range of 118–120°C, and a vapor pressure near 11 mmHg at 20°C. The product is highly soluble in water and ethanol, enabling straightforward integration into aqueous flavor systems, pickling brines, and fermentation workflows. This acid also serves as an effective microbial inhibitor and pH control agent, enabling precise acidity management in sauces, dressings, marinades, and other preserved foods. All lots are documented with COA data showing compliance with food-grade standards and low heavy metals content, reinforcing reliability for industrial use.

Common Applications

• Application Category: Food Preservative — Used to preserve food products by lowering pH and inhibiting microbial growth, supporting shelf stability and safety in acidic formulations.
• Flavoring Agent: Commonly used in sauces, dressings, and marinades to provide characteristic acidity and tang to culinary profiles.
• pH Adjuster: Utilized to adjust the acidity of food products to target levels for texture, color stability, and microbial control.
• Chemical Reagent: Serves as a reagent in laboratory syntheses and analytical workflows where acetic acid is required as a standard or solvent component.
• Solvent: Acts as a solvent in industrial processes and pharmaceutical intermediate production where water miscibility is advantageous.
• Food Processing Aid: Integrated into manufacturing pipelines to control fermentation pH and assist cleaning-in-place (CIP) routines due to its buffering and antimicrobial properties.
• Fermentation Control: Used in fermentation-based product lines to regulate acidification and flavor development with consistent quality.
• Pickling Solutions: Forms the acidic backbone of pickling brines, contributing to texture, microbial suppression, and flavor development.

Safety Precautions

Handle and store Acetic Acid Glacial - Food Grade under conditions that minimize exposure and moisture ingress. Store in a cool, dry place away from direct sunlight in HDPE or glass containers. Maintain ventilation to control vapor buildup and wear appropriate PPE including chemical-resistant gloves, goggles, and lab coat. Use within a designated area with spill containment and proper waste handling procedures consistent with SDS.

In addition, ensure compatibility with inert atmosphere handling to prevent moisture absorption and monitor trace metal levels to maintain compliance with food-grade standards. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical attention if irritation persists. Follow emergency procedures for spills, leaks, or exposure, including neutralization and proper disposal per regulatory requirements. Refer to the SDS for transport classification UN 2789 and corrosivity details.
