97.5% Powder Sodium Metabisulfite Wine Preservative E223 Use

Sodium Metabisulfite, identified by the CAS number 7681-57-4, is a versatile chemical compound widely used across various industries due to its excellent properties as a preservative, antioxidant, and disinfectant. This compound is a white, crystalline powder that typically comes in a granularity of 80-100 mesh, ensuring a fine consistency suitable for diverse applications. Sodium Metabisulfite is well-known for its effectiveness in preventing oxidation and spoilage, making it an essential additive in food preservation, water treatment, photography, and chemical manufacturing.

The physical properties of Sodium Metabisulfite include a melting point of approximately 150 °C, at which it decomposes rather than melts, reflecting its chemical stability under standard conditions. This characteristic makes it particularly useful in processes that require thermal resistance up to moderate temperatures. The compound’s granular form, ranging between 80 to 100 mesh, facilitates easy dissolution and uniform distribution in liquid or solid mixtures, enhancing its functional performance in industrial and commercial uses.

One of the primary identifiers of Sodium Metabisulfite is its CAS number 7681-57-4, which is universally recognized and used for regulatory, safety, and quality control purposes. This unique chemical identifier ensures that the product is consistently produced and supplied according to international standards, maintaining high purity and reliability. Industries rely on this CAS number to verify the authenticity and compliance of Sodium Metabisulfite in their supply chains.

When it comes to packaging and transportation, Sodium Metabisulfite is securely packed in plastic woven bags with a PE liner. This packaging style is designed to protect the chemical from moisture, contamination, and external environmental factors during transit and storage. The robust packaging ensures the integrity and quality of Sodium Metabisulfite are preserved from the manufacturer to the end user, enabling safe handling and efficient logistics management.

Sodium Metabisulfite’s applications are diverse and critical. In the food industry, it acts as a preservative and antioxidant, helping to extend the shelf life of dried fruits, beverages, and processed foods by preventing discoloration and microbial growth. In water treatment, it serves as a dechlorinating agent, neutralizing excess chlorine to make water safe for discharge or further use. Additionally, it is employed in the photographic industry as a reducing agent in film developing processes. The chemical also finds use in the textile and leather industries for bleaching and as a reducing agent in dyeing processes.

Safety and handling of Sodium Metabisulfite are paramount due to its chemical nature. While it is highly effective and useful, appropriate measures should be taken to avoid inhalation or contact with skin and eyes, as it may cause irritation. Proper storage in sealed, moisture-proof packaging, like the plastic woven bags with PE liners, helps mitigate these risks and ensures the chemical remains stable and effective throughout its shelf life.
