Production Process and Impact on Olive Juice Composition

The composition of olive juice varies significantly depending on the curing method used and subsequent processing steps. The main types of olive curing methods include water curing, brine curing, lye curing, and dry curing. Each method influences the chemical makeup of the juice differently:

  • Water Curing: Olives are soaked in water to leach out bitterness, resulting in a dilute olive juice with low salt content and mild acidity.
  • Brine Curing: Olives are submerged in a saltwater solution for extended periods. This process enriches the olive juice with salt and organic acids from fermentation, increasing its preservative qualities.
  • Lye Curing: Sodium hydroxide is used to chemically remove bitter compounds. The lye is rinsed off, and olives are often stored in brine afterward. This method results in juice with reduced bitterness but altered chemical composition.
  • Dry Curing: Olives are packed in salt without added liquid, producing minimal juice. The residual juice tends to be highly concentrated in salts and polyphenols.

Fermentation plays a critical role in shaping olive juice. Lactic acid bacteria metabolize sugars, producing organic acids that lower pH and enhance microbial safety. This also modifies flavor profiles, increasing complexity.
