Optimization of Extraction Parameters for Phenolics Recovery from Avocado Peels Using Ultrasound and Microwave Technologies

Q: What does this research mean for the field?

Ultrasound-assisted extraction is more efficient than microwave-assisted extraction for recovering phenolic compounds from avocado peels, yielding higher concentrations of procyanidins at lower temperatures and shorter extraction times. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

This research aims to optimize extraction methods for phenolic compounds from avocado peels using ultrasound and microwave technologies.
Utilized Central Composite Design to assess extraction parameters.
Measured ethanol concentration, temperature, and time for both ultrasound-assisted extraction (UAE) and microwave-assisted extraction (MAE).
Conducted analysis of total antioxidant capacity and total phenolic compounds, as well as individual phenolics via HPLC/MS.
Optimal UAE conditions were 94.55% ethanol at 45 °C for 5 min, significantly enhancing procyanidin recovery (+15%).
MAE required higher temperatures (67 °C for 12 min) with comparable antioxidant extraction outcomes.
Both extraction methods proved effective, promoting sustainability in the agri-food sector.
