75% Diluted Acetic Acid Food Grade

Product Overview

75% Diluted Acetic Acid Food Grade is a clear, colorless solution of acetic acid (CH₃COOH) designed for culinary and food-processing applications where controlled acidity and preservative action are required. This food-grade acidifier meets Food Chemical Codex specifications and is formulated to support consistent performance across batches. The solution exhibits a sharp, pungent odor typical of high-purity acetic acid and is readily miscible with water, enabling precise control of acidity in dressings, marinades, pickling brines, and preserved products. Typical assay is 75.5% by weight, with a low residue after ignition, ensuring minimal inorganic carryover and compatibility with downstream processing equipment. The product is supplied in containers compatible with acetic acid (HDPE or glass) and is intended for industrial, institutional, and large-scale culinary operations.

It is suitable for use as a flavoring adjunct, pH adjustment agent, and preservative in food manufacturing. By maintaining strict specification control for heavy metals and inorganic impurities, the product supports compliance with regulatory and quality assurance programs. Storage and handling follow standard chemical hygiene practices to preserve potency and minimize vapor exposure in well-ventilated facilities.

• pH Adjustment: Fine-tunes acidity in food formulations, enabling stability and microbial control in processing environments.
• Ingredient in Pickling: Integral component in brines and pickling solutions for texture and preservation improvements.
• Cleaning Agent: Diluted form used to sanitize food preparation surfaces when compatibility with materials is confirmed.
• Green and Clean Label Processing: Supports clean-label objectives with well-defined food-grade specifications and traceable impurities profile.

Safety Precautions

Handle with appropriate protective equipment including chemical splash goggles, chemical-resistant gloves, and lab/industry-standard PPE. Store in a cool, dry place away from direct sunlight in HDPE or glass containers, with venting to avoid vapor buildup. Ensure containers are properly labeled and segregated from incompatible materials such as strong oxidizers and bases. Maintain good ventilation in storage and handling areas to minimize exposure risk.

In case of contact with skin or eyes, rinse immediately with copious amounts of water for several minutes and remove contaminated clothing. If inhaled, move to fresh air and seek medical attention if symptoms persist. For ingestion, rinse mouth and do not induce vomiting; seek medical advice promptly. Transport as UN 2790, Acetic acid solution, Class 8, PG II, and follow applicable regulatory requirements for hazardous liquids.
