Description
Acid-preserved fruit syrup balancing sugar's osmotic action with vinegar's microbial inhibition.
Technical
Osmotic dehydration extracts fruit juices into sugar solution while acetic acid prevents spoilage via pH reduction below 4.6, with esterification creating new aroma compounds.
Culinary Significance
Provides shelf-stable fruit flavoring for beverages, marinades, and dressings without refrigeration.
