Overview

Diluted Acetic Acid Food (CAS 64-19-7) is a food-grade aqueous solution of acetic acid that serves as an essential ingredient in food processing, preservation, and manufacturing operations. This clear, colorless liquid with a characteristic pungent, vinegar-like odor is miscible with water and provides reliable acidification and antimicrobial properties for various culinary and industrial food applications.

Key Applications

  • Food Preservation: Acts as a natural preservative to inhibit bacterial growth and extend shelf life in processed foods, condiments, and prepared meals
  • pH Adjustment: Controls acidity levels in food processing to ensure product stability, flavor optimization, and regulatory compliance
  • Vinegar and Pickling Production: Essential component in commercial vinegar manufacturing and pickling operations for vegetables, fruits, and other food products
  • Cleaning and Sanitation: Provides effective antimicrobial action for food-contact surfaces and equipment sanitization in food processing facilities

Safety & Handling

While diluted acetic acid is generally safer than concentrated forms, proper handling procedures remain essential. The flash point of pure acetic acid is 40°C, requiring careful storage away from heat sources and ignition points. Personal protective equipment including chemical-resistant gloves, safety goggles, and adequate ventilation should be used during handling. The pH of approximately 2.4 in 1 M solution indicates acidic properties that require appropriate precautions to prevent skin and eye contact.

Storage & Shelf Life

Store in cool, dry conditions away from incompatible materials such as strong bases, oxidizing agents, and reactive metals. Use corrosion-resistant containers made of stainless steel, glass, or compatible plastics. Maintain storage temperatures below the boiling point to prevent vapor formation and ensure container integrity. Properly stored material maintains quality for extended periods when kept in original sealed containers.

Frequently Asked Questions

What is Diluted Acetic Acid Food and what is it used for?
Diluted Acetic Acid Food is a food‑grade aqueous solution of acetic acid offered at various concentrations for industrial and laboratory use. It is used where a controlled acidic ingredient or reagent is required in processes such as food processing (where permitted by regulation), cleaning, pH adjustment and laboratory protocols.
How should Diluted Acetic Acid Food be stored and what is its shelf life?
Store in a cool, dry, well‑ventilated area away from direct sunlight and incompatible materials; keep containers tightly closed. Typical unopened shelf life is 12–24 months depending on concentration and storage conditions — consult the product COA for lot‑specific expiry.
What safety precautions and personal protective equipment are recommended when handling this product?
Use chemical‑resistant gloves, eye protection, and adequate ventilation or respiratory protection if needed; avoid skin and eye contact and inhalation of vapors. Refer to the Safety Data Sheet (SDS) for first‑aid measures, spill response and specific PPE recommendations.
How do the different concentrations (75%, 50%, 30%, 20%, 10%, 5%) affect performance and hazard level?
Higher concentrations have stronger acidity and corrosive potential, requiring more robust materials, PPE and transportation controls; lower concentrations are less aggressive but still acidic. Choose a concentration based on the technical requirements of the application and applicable safety/regulatory constraints.
What documentation is provided with Diluted Acetic Acid Food (SDS, COA, TDS)?
Standard documentation includes a Safety Data Sheet (SDS), Certificate of Analysis (COA) for each lot, and a Technical Data Sheet (TDS) outlining specifications and handling. Additional documents (GMP statements, allergen declarations, regulatory compliance letters) can be supplied on request.
How is Diluted Acetic Acid Food packaged and shipped?
Common packaging options include small bottles, HDPE drums, IBC totes and bulk tankers depending on order size; custom packaging is available. Shipping classification and labeling depend on concentration and local hazardous goods regulations, so carriers require the SDS and exact product details prior to shipment.
What materials are compatible with Diluted Acetic Acid Food and which should be avoided?
Stainless steels (304/316), glass and many plastics (HDPE, PP) are generally compatible for typical concentrations; compatibility depends on concentration, temperature and exposure time. Avoid plain carbon steel, certain aluminum alloys and some elastomers without confirmed compatibility; always consult a chemical compatibility chart for your exact conditions.
What are the key technical specifications for Diluted Acetic Acid Food?
Available concentrations: 75%, 50%, 30%, 20%, 10% and 5% (w/w); product is a clear, colorless liquid with assay and impurity limits provided on the COA. Specific gravity, pH and titratable acidity are reported per lot — request the TDS/COA for numeric values for a given batch.
Which industries and applications commonly use Diluted Acetic Acid Food?
Typical users include food and beverage processors (for authorized uses), industrial cleaners, chemical manufacturers and research laboratories for pH control, acidification steps and reagent preparation. Use in any food application should comply with local food safety regulations and supplier documentation.
How can I purchase Diluted Acetic Acid Food and what are typical lead times and minimum order quantities?
Contact the supplier or sales representative for pricing, minimum order quantities and available packaging; standard stock items are often available for immediate shipment. Lead times vary by quantity and location — suppliers can provide firm delivery estimates once order details are confirmed.
