Pressurized Liquid Extraction Optimization from Supercritical Defatted Olive Pomace: A Green and Selective Phenolic Extraction Process

What if the leftover pulp from olive oil production could be transformed into a treasure trove of health-boosting compounds? A new green extraction method does just that, unlocking phenolics with unprecedented efficiency.

Olive pomace, the main by-product of olive oil production, is generated in massive quantities. But it's not just waste—it's a goldmine of phenolic bioactive compounds. Researchers have now developed an intensified process to maximize their recovery using hydroalcoholic mixtures, starting with a supercritical CO2 defatting pre-treatment.

Key Points

• Supercritical CO2 defatting pre-treatment enhanced phenolic recovery.
• Optimized extraction boosted key compounds by 475% (oleuropein).
• Green process: 67% shorter time, 38% less solvent.
