Citric Acid, Malic Acid Preservative
Consumer demand for sustainable, safe, natural alternatives to synthetic preservatives is rising, along with clean-label preferences. CD BioSustainable develops citric and malic acid-based solutions—GRAS fruit acids with antimicrobial activity. Our service provides customized systems to inhibit microbes, extend shelf life, and meet sustainability goals, from formulation to scale-up.

Technical Principles
Both citric acid and malic acid act as preservatives through several pathways:
- Reduction in pH: Decreasing the pH level of food substances makes it more difficult for bacteria, yeast, and molds to thrive.
- Chelation of Metal Ions: Both acids inhibit microbial activity by way of bounding to vital metal ions such as iron and calcium, which are critical to microbial enzymes and, thereby, disrupting catalytic and metabolic pathways.
- Membrane Disruption: Undissociated acid molecules penetrate microbial cell membranes and acidify the cytoplasm resulting in cell death.
- Synergistic Effects: When combined with other natural antimicrobials (e.g., plant extracts, bacteriocins), these acids enhance preservative efficacy through multi-target action.
We have designed a bio preservative acid blend which optimizes the preservation system by enhancing the acid concentration, delivery system, and compatibility into food matrices to greatly enhance preservation efficacy while having the least sensory impact.
Technical Features
- Natural Origin: Sourced from renewable biomass, aligning with clean-label trends.
- Broad-Spectrum Efficacy: Effective against common spoilage organisms (e.g., Lactobacillus, Aspergillus) and pathogens (e.g., E. coli, Salmonella).
- pH Stability: Maintains functionality across a wide pH range (2.5-5.5), ideal for acidic to mildly acidic foods.
- Thermal Resistance: Retains antimicrobial activity post-pasteurization or UHT processing.
- Flavor Compatibility: Complements fruity and tart flavor profiles without introducing bitterness.
Application Areas
- Beverages: Juices, soft and functional drinks.
- Dairy: Yogurts, cheeses and plant based alternatives.
- Bakery and Confectionery: Bread, cakes and fruit filled pastries.
- Processed Meat: Cured and ready to eat meat products.
- Ready Meals: Sauces, soups, entrees chilled or frozen.
