Description
Plant-based curing uses natural nitrates, salts, sugars, and polyphenols to preserve protein foods while imparting characteristic flavors.
Technical
Plant-derived nitrates (e.g., celery powder, beetroot) are enzymatically reduced to nitrites in an acidic matrix, providing 200–300 ppm nitrite that inhibits Clostridium botulinum and contributes cured flavor. Concurrently, a 1:1 salt–sugar blend creates osmotic pressure that dehydrates the surface, lowering water activity below 0.85 and suppressing spoilage bacteria. Polyphenol-rich extracts act as antioxidants, delaying lipid oxidation and extending shelf life.
