10% Diluted Acetic Acid Food Grade

Product Overview

10% Diluted Acetic Acid Food Grade is a clear, colorless liquid solution of acetic acid (C₂H₄O₂) in water, formulated to meet stringent food-grade specifications for safe culinary use and食品 preservation processes. With a typical assay of 10 wt%, this solution provides a balanced acidity suitable for preserving, flavor enhancement, and controlled pH adjustment in a variety of food matrices. The product adheres to Food Grade specifications and is designed for repeatable performance in commercial kitchens, food processing, and beverage production, where precise acidity and purity are critical for product integrity and regulatory compliance.

As a versatile diluent and functional acid, this 10% solution supports applications ranging from pickling and fermentation to surface cleaning in food-service environments. The formulation emphasizes low impurity levels, controlled residue after ignition, and compatible characteristics with standard food-contact processing equipment. Its compatibility with water-based systems and stable storage profile under recommended conditions make it a reliable component for process control, quality assurance, and batch-to-batch consistency in industrial food operations.

Common Applications

• Food Preservation: Used as a preservative in pickling and food storage to inhibit microbial growth and extend shelf life within established safety guidelines.
• Flavoring Agent: Employed to impart or balance acidity and flavor notes in dressings, sauces, marinades, and culinary formulations.
• pH Adjustment: Utilized to adjust pH levels in food processing to achieve safety, texture, and stability targets, with controlled dosing in large-scale operations.
• Cleaning Agent: Serves as a natural cleaner for kitchen surfaces and equipment, leveraging acidity for effective sanitization in food-service environments.
• Fermentation Aid: Acts as a fermentation aid in beverage production, including vinegar and related fermentation processes, contributing to consistent fermentation profiles.

Safety Precautions

Handling and storage should follow established SDS guidelines. Store in a cool, dry place away from direct sunlight in HDPE containers, with adequate ventilation to prevent vapor accumulation. Use appropriate PPE including chemical-resistant gloves, eye protection, and aprons to prevent skin and eye contact. Keep containers tightly closed when not in use and monitor for signs of leakage or degradation. Ensure compatibility with storage systems and avoid contact with strong oxidizers and bases to prevent hazardous reactions.

Additional safety considerations include routine exposure monitoring, adherence to labeling requirements, and ensuring that handling practices align with industrial hygiene standards. In case of spills, evacuate the area, ventilate, contain with inert absorbent material, and dispose of according to local regulations. This product is classified with hazard statements for eye and skin irritation (H319, H315) and carries a WARNING signal word on the SDS for safe handling and emergency response planning.
