Stability of Sorbic Acid in Model Food Systems of Reduced Water Activity: Sugar Solutions

The behavior of sorbic acid in model systems comprised of concentrated sugar solutions (water activity 0.94) at pH 3.5 and 4.5 was studied. Sorbic acid degraded appreciably as a function of time and temperature during storage and its destruction could be described by first‐order kinetics. The rate c...
