To inhibit the growth of mold in products such as bread, cheese, fruit juice, and dried fruit, food processors utilize specific antimicrobials known as antimycotics.1
Key preservatives used for this purpose include:
- Propionates: Sodium and calcium propionate are commonly used to prevent mold growth. Propionic acid functions by disrupting cell membrane function.12
- Sorbic Acid: This organic acid is effective against molds, yeasts, and some bacteria by inhibiting enzymes and disrupting cell membrane function.32
- Sulfur Dioxide and Sulfites: These are frequently used to control spoilage microorganisms in dried fruits and fruit juices.3
- Natamycin: This preservative, which is produced by microorganisms, is specifically active against molds and yeasts by binding to sterol groups in fungal cell membranes.32
- Benzoic Acid: This agent is also used to inhibit the growth of molds and yeasts.2
