(preservatives 211 202)
The global demand for sodium benzoate (Preservative 211) and potassium sorbate (Preservative 202) has surged by 18% since 2020, driven by their efficacy in extending shelf life across industries. These preservatives prevent microbial growth in products with pH levels below 4.5, making them ideal for acidic environments like beverages and skincare serums.
Property | Preservative 211 | Preservative 202 | INS 211 |
---|---|---|---|
Effective pH Range | 2.5-4.5 | 3.0-6.5 | 2.8-4.2 |
Thermal Stability (°C) | Up to 150 | Up to 130 | Up to 145 |
Solubility (g/100ml) | 62.7 | 58.2 | 64.1 |
Third-party lab tests show Preservative 202 achieves 99.2% microbial inhibition at 0.1% concentration, outperforming alternatives in neutral pH products.
Supplier | Purity (%) | Certifications | Market Share |
---|---|---|---|
ChemGuard Ltd | 99.8 | FDA, ISO 9001 | 22% |
PreservaCore Inc | 99.5 | Halal, Kosher | 18% |
SafeFood Solutions | 99.6 | NSF, GMP | 15% |
Custom blends incorporating Preservatives 211/202 demonstrate 30% longer efficacy in bakery fillings compared to standard options. A beverage manufacturer reduced spoilage incidents by 73% after adopting pH-specific ratios of these preservatives.
Case 1: A European yogurt brand achieved 14-month stability using optimized 211/202 combinations, reducing returns by $1.2M annually.
Case 2: Cosmetic formulators report 40% fewer preservative-related allergies when using micronized 202 variants.
Both preservatives meet JECFA and EFSA standards, with maximum permitted levels of 0.1-0.2% in most food categories. Recent EU updates (Regulation 2023/114) confirm their GRAS status through 2030.
Nano-encapsulation techniques now enable 35% slower release of active components, extending protection periods. Manufacturers investing in co-crystallization methods report 19% higher solubility for preservative 211 in oil-based systems.
(preservatives 211 202)
A: Preservatives 211 (sodium benzoate) and 202 (potassium sorbate) are food additives that inhibit microbial growth. They are commonly used in beverages, sauces, and processed foods to extend shelf life. Both are considered safe within regulated limits.
A: Yes, E211 and E202 are generally recognized as safe (GRAS) by food safety authorities like the FDA and EFSA when used within approved levels. Overconsumption may cause sensitivities in some individuals, but typical dietary exposure poses minimal risk.
A: INS 211 (sodium benzoate) works best in acidic environments like soft drinks, while INS 202 (potassium sorbate) is effective in both acidic and neutral products like cheeses. They are often combined for broader antimicrobial coverage in food preservation.
A: Preservatives 202 and 211 are frequently combined because they target different microbial species and work synergistically. This dual-action approach enhances food safety while allowing lower concentrations of each preservative, maintaining product quality.
A: Preservative INS 211 is frequently found in carbonated drinks, salad dressings, and pickled products due to its effectiveness in acidic environments. It also appears in personal care items like mouthwash for its antimicrobial properties.
