Why Preservation Matters
Natural plant hydrocolloid solutions are susceptible to bacterial attack. Proper preservation is essential for safety and functionality.
Food-Grade Methods
Sodium benzoate + citric acid — most commonly recommended. Sorbic acid and/or potassium sorbate — particularly effective in processed cheese applications.
Best Practices
Prepare fresh when possible, add preservatives immediately. Maintain pH below 4.5 for optimal preservative effectiveness. Store cool. Follow GMP for handling/sanitation.
