AI Insight
This study investigated how adjusting the pH of olive paste during malaxation (the mixing process before oil extraction) affects the chemical and sensory properties of virgin olive oil. Researchers found that lowering the paste pH during malaxation increased the extraction of phenolic compounds and improved the oxidative stability of the resulting oil. The modifications also enhanced certain desirable sensory attributes while maintaining oil quality parameters within acceptable ranges.
Why it matters
Understanding pH optimization during olive oil production could help producers create oils with enhanced nutritional properties and longer shelf life. This knowledge may allow the industry to improve oil quality through simple processing adjustments without requiring new equipment or additives.
