Food Preservative Calcium Propionate (E282) - High-Quality Powder for Bakery and Food Preservation
Introduction to Calcium Propionate in Food Preservation
Calcium Propionate (E282) is one of the most widely used and scientifically validated preservatives in the global food industry, particularly valued for its exceptional ability to inhibit mold and extend shelf life in bakery products. Our high-quality Calcium Propionate powder meets stringent food-grade standards, providing manufacturers with a safe, effective solution for maintaining freshness while complying with international food safety regulations.
Key Features & Product Specifications
Chemical Formula: C₆H₁₀CaO₄
Purity: ≥99% food-grade quality
Appearance: Fine white crystalline powder
Solubility: Highly soluble in water (49g/100ml at 20°C)
pH Stability: Most effective in pH range 5.0-7.5
Certifications: Complies with FCC, USP, EU (E282), and FDA (21CFR184.1221) standards
Mechanism of Action: How Calcium Propionate Works
Calcium Propionate functions as a mold and rope inhibitor through multiple biochemical pathways:
Metabolic Disruption: Propionic acid penetrates microbial cells and interferes with enzyme systems critical for energy production.
pH Modulation: The released propionic acid lowers intracellular pH in microorganisms, creating an inhospitable environment.
Calcium Synergy: The calcium component contributes to dough strengthening in bakery applications while enhancing preservation.
This triple-action mechanism provides broad-spectrum protection against:
Bread molds (Aspergillus, Penicillium, Rhizopus)
Rope-forming bacteria (Bacillus mesentericus)
Certain yeasts and other spoilage microorganisms
Primary Applications in Food Industry
1. Commercial Baking (Major Application)
Bread Preservation: Extends shelf life by 3-5 days in standard loaves
Buns & Rolls: Prevents surface mold in hamburger buns and dinner rolls
Cakes & Pastries: Maintains freshness in high-moisture baked goods
Tortillas & Flatbreads: Controls microbial growth in low-acid products
Recommended Usage: 0.1-0.3% of flour weight (varies by recipe and desired shelf life)
2. Other Food Applications
Dairy Products: Effective in certain cheeses and cultured dairy items
Processed Meats: Approved for use in some meat applications (check regional regulations)
Animal Feed: Prevents mold in moist feed formulations
Technical Advantages for Food Manufacturers
1. Superior Performance Characteristics
Heat Stability: Maintains efficacy through baking temperatures up to 200°C (392°F)
Dough Compatibility: Does not interfere with yeast fermentation when used at proper levels
Synergistic Effects: Often combined with sorbates for enhanced mold inhibition
2. Quality Preservation Benefits
No Flavor Impact: Neutral taste profile at recommended usage levels
Color Protection: Helps maintain natural product appearance
Texture Maintenance: Calcium content can improve dough handling properties
3. Operational Advantages
Easy Incorporation: Powder blends uniformly with dry ingredients
Dosing Precision: Consistent particle size ensures accurate measurement
Cost Efficiency: Lower dosage requirements compared to some alternatives
Regulatory Status & Safety Profile
Calcium Propionate enjoys global regulatory acceptance:
FDA Status: GRAS (Generally Recognized As Safe)
EU Approval: Listed as E282
Codex Alimentarius: Permitted in standardized foods
JECFA ADI: Established at 0-50mg/kg body weight
Extensive toxicological studies confirm:
No evidence of carcinogenicity or mutagenicity
Metabolized naturally through fatty acid pathways
Considered one of the safest chemical preservatives
Usage Guidelines & Best Practices
Optimal Application Parameters:
pH Consideration: Most effective in slightly acidic to neutral foods (pH 5-7.5)
Water Activity: Works best in products with aw >0.90
Distribution: Requires thorough mixing for uniform protection
Combination Use: Often paired with potassium sorbate for broader spectrum
Typical Dosage Ranges:
White bread: 0.1-0.15% of flour weight
Whole grain products: 0.2-0.3% (higher due to natural mold inhibitors)
Cakes & sweet goods: 0.1-0.2%
