Carbon Dioxide Food Grade
Food Grade Carbon Dioxide (CO2) is a high-purity industrial gas essential for various food and beverage applications.
Description
Carbon Dioxide (CO2) is a colorless, odorless, and non-flammable gas with the chemical formula CO2 and CAS number 124-38-9. This food-grade variant is produced and purified to meet stringent international standards for use in direct contact with consumables. It is typically supplied in compressed or liquefied form. Its unique properties, including solubility in water to form carbonic acid, make it invaluable across numerous industries. CO2 is significantly denser than air and acts as a mild anesthetic in high concentrations. Its chemical inertness under normal conditions contributes to its wide range of applications, especially where stability and purity are paramount. The production process involves capturing CO2 from fermentation, combustion, or natural sources, followed by multi-stage purification and quality control to ensure compliance with food and beverage safety regulations, ensuring no contaminants affect product integrity or consumer health.
Applications
Food Grade Carbon Dioxide is extensively utilized in the beverage industry for carbonation of soft drinks, beer, and sparkling wines, providing effervescence and extending shelf life. In food processing, it serves as a chilling and freezing agent for meats, poultry, baked goods, and prepared meals, rapidly cooling products to maintain quality and inhibit bacterial growth. It is also employed in modified atmosphere packaging (MAP) to preserve freshness and extend the shelf life of perishable goods by inhibiting microbial spoilage and oxidative degradation. Other applications include inerting storage tanks and silos to prevent oxidation and pest infestation, extraction of natural products (e.g., decaffeination of coffee, extraction of essential oils) using supercritical CO2, and as a component in greenhouse cultivation to enhance plant growth.
Storage & Handling
Store in a cool, well-ventilated area away from direct sunlight and heat sources. Keep containers upright and secured to prevent falling. Ensure proper ventilation during use. Handling should only be performed by trained personnel, using appropriate personal protective equipment.
