Introduction

Calcium Sorbate (E203) provides the antimicrobial benefits of sorbic acid with simultaneous calcium fortification. This makes it particularly attractive for dairy and bakery applications where both preservation and nutritional enhancement are desired. Like other sorbates, the undissociated form of sorbic acid is the active antimicrobial species, with a pKa of 4.76.

This makes it effective in mildly acidic to neutral pH environments (pH 3–6.5). Its mechanism involves inhibition of dehydrogenase enzymes in microbial cells, disruption of membrane transport, and interference with spore germination. Calcium Sorbate is approved under EU Regulation 1333/2008, Codex Alimentarius, and various national food laws. JECFA established an ADI of 0–25 mg/kg body weight for sorbic acid and its salts combined.

Uses

  • Cheese and dairy products (surface treatment and inclusion)
  • Baked goods and bakery products
  • Wine and fermented beverages
  • Dried fruits and fruit preparations
  • Margarine and fat spreads
