Sodium Benzoate for foods (CAS No.: 532-32-1, E Number: E211) serves as a fundamental and highly reliable preservative specifically formulated for the food and beverage industry. Presented as a white, free-flowing granular powder, this food-grade ingredient is engineered to deliver consistent antimicrobial performance, particularly in acidic environments.
Our Sodium Benzoate maintains a stringent purity level of ≥99.5%, ensuring minimal impurities that could affect the final product's sensory profile. With a moisture content of ≤ 1.5% and a pH range of 8.0–10.0 (in a 1% aqueous solution), it offers dependable stability during both raw material storage and manufacturing processes.
For global food manufacturers, regulatory compliance is a critical factor in ingredient selection. This product strictly adheres to international safety standards, including FDA 21 CFR §184.1733, EU Regulation (EC) No. 1333/2008, and China’s GB 1886.184-2022. Furthermore, it holds a JECFA-approved Acceptable Daily Intake (ADI) of 5mg/kg·bw, providing formulators with the necessary assurance to develop safe, market-ready consumer goods.
When formulating acidic food products, determining the correct dosage is essential for maximizing shelf life while adhering to regulatory limits. Sodium Benzoate is highly effective against yeast, mold, and certain bacteria, making it an indispensable ingredient across various food categories.
Carbonated Beverages: Typically added at a precise rate of 0.02%–0.05% in formulations like cola, fruit sodas, and energy drinks. At this concentration, it actively prevents yeast fermentation, thereby maintaining proper carbonation levels and extending the commercial shelf life up to 12 months without altering the beverage's taste.
Pickled Products: For fermented or vinegar-based vegetables such as pickles and sauerkraut, an incorporation rate of 0.05%–0.1% is recommended. It effectively inhibits the overgrowth of lactic acid bacteria and other spoilage microorganisms, helping to retain the desired crisp texture and tangy flavor profile for up to 9 months.
Fruit Preserves: In the production of jams, jellies, and marmalades, manufacturers utilize a dosage of 0.05%–0.15%. This application prevents surface mold growth and minimizes syneresis (whey or liquid separation), ensuring product stability and visual appeal throughout an extended 18 months of shelf life.
Acidic Sauces: Mixed directly into condiments like ketchup, mustard, and vinegar-based salad dressings at 0.05%–0.1%. It stabilizes complex flavor structures and prevents bacterial spoilage, maintaining the sauce's integrity for 6 months under standard retail conditions.
Q: Is sodium benzoate safe to use in formulations containing vitamin C (ascorbic acid)?
A: Yes, it is safe when formulation parameters are strictly controlled. The primary concern is the potential formation of benzene. However, by maintaining a product pH of < 3.5 and ensuring storage temperatures remain < 40°C, benzene formation is negligible (typically < 1ppb). This is well below the FDA’s stringent 5ppb safety limit for beverages, allowing for safe co-formulation.
Q: Can this product completely replace potassium sorbate in all food applications?
A: No, the choice between these preservatives depends heavily on the product's pH level. Sodium Benzoate is highly effective in acidic environments but becomes largely ineffective at a pH > 4.5. For neutral or low-acid foods (such as bread or dairy products), potassium sorbate is required. For high-acid products, Sodium Benzoate offers targeted efficacy and better cost control.
Q: What are the specific shelf life and storage requirements for raw material inventory?
A: To maximize the ingredient's viability, it should be stored in tightly sealed, airtight containers within a temperature range of 15°C–30°C and a relative humidity of ≤ 70%. Under these controlled warehouse conditions, the shelf life extends up to 36 months. It is crucial to avoid any contact with strong oxidizers to prevent chemical degradation during long-term storage.
When selecting a preservative for commercial food production, balancing microbial control, formulation costs, and production efficiency is critical. Our Sodium Benzoate for Foods is engineered to deliver reliable protection against spoilage while optimizing your manufacturing workflow. By integrating this preservative into your production lines, procurement teams and formulators can achieve extended shelf life and maintain product integrity without escalating operational costs.
High Efficacy & Acid-Stable Preservation: Effectively extending the shelf life of food products requires targeted microbial control, especially in challenging formulations. This sodium benzoate offers exceptional performance in acidic environments, providing optimal preservation within a pH range of 2.5 to 4.0. Within these parameters, it achieves up to a 99.9% microbial inhibition rate against yeast, mold, and certain bacteria, ensuring safety and freshness while significantly reducing the risk of premature spoilage.
Significant Cost Advantage: Managing ingredient costs is a priority for large-scale food manufacturing. Compared to alternative preservatives, this sodium benzoate provides a highly economical solution for your formulation needs. It delivers up to a 60% cost reduction when evaluated against potassium sorbate, allowing procurement managers to optimize their ingredient budgets without compromising on preservation performance.
Rapid Solubility & Dispersion: Production efficiency relies on ingredients that integrate smoothly into existing manufacturing processes. Our sodium benzoate is characterized by its excellent solubility, dissolving completely in water within just 2 minutes under standard processing conditions. This rapid dispersion eliminates the need for prolonged mixing times, streamlining your production workflow and preventing localized concentration issues in the final food matrix.
Improves Food Stability & Color Preservation: Maintaining the visual appeal and structural integrity of food products over time is essential for consumer acceptance. This preservative helps maintain the overall integrity of food products, preventing spoilage and deterioration throughout the intended shelf life. Furthermore, it supports up to 80% color retention in sensitive formulations such as fruit juices and fruit-based preserves, ensuring the final product remains visually appealing from the factory floor to the consumer.
Versatile Applications & Broad Compatibility: Suitable for a wide range of food types, including both acidic and non-acidic products, enhancing its utility across various formulations. Its broad compatibility with other food additives and stabilizers can help streamline complex manufacturing recipes. In certain synergistic applications, its efficiency can even help reduce overall preservative usage by up to 30%, simplifying the ingredient list while maintaining robust protection.
Strong Safety Profile & Widely Researched: As a well-established preservative, sodium benzoate has a long history of safe use in the food industry, contributing to consumer confidence. It complies with stringent food additive regulations and is widely accepted globally, making it a dependable choice for manufacturers. This strong safety profile ensures that your products meet compliance standards while delivering the quality that consumers expect.
