Summary
This study recovered valuable phenolic compounds from quince peel using ultrasound-assisted extraction (UAE). The optimized extract enhanced chitosan/polyvinyl alcohol (PVA) edible films, improving properties and preserving fresh-cut pineapple quality for sustainable food packaging.
Area of Science:
- Food Science and Technology
- Materials Science
- Biochemistry
Background:
- Agro-industrial by-products like quince peel are rich in phenolic compounds.
- Valorization of these by-products can lead to sustainable functional ingredients.
- Edible films offer promising solutions for food packaging and preservation.
Purpose of the Study:
- To optimize ultrasound-assisted extraction (UAE) of phenolic compounds from quince peel.
- To incorporate the optimized quince peel extract into chitosan/polyvinyl alcohol (PVA)-based edible films.
- To evaluate the functional properties of the developed edible films and their application in fresh-cut pineapple preservation.
Main Methods:
- Response Surface Methodology (RSM) with Central Composite Design (CCD) for extraction optimization.
- Ultrasound-Assisted Extraction (UAE) for phenolic compound recovery.
- Solvent casting for edible film preparation and characterization (FT-IR, SEM, mechanical, barrier properties).
- Application testing on fresh-cut pineapple stored at 4°C for 14 days.
Main Results:
- Optimized UAE yielded high total phenolic content (23.90 mg GAE/g QP) and antioxidant capacity (ABTS: 9.56 mg TE/g QP, FRAP: 18.64 mg TE/g QP).
- Incorporation of quince peel extract into chitosan/PVA films improved water vapor barrier properties and flexibility, with good polymer compatibility.
- Edible films containing quince peel extract significantly enhanced visual quality preservation and retained higher phenolic content and antioxidant capacity in coated fresh-cut pineapple.
Conclusions:
- Ultrasound-assisted extraction is effective for valorizing quince peel by recovering bioactive phenolic compounds.
- Quince peel extract can be successfully incorporated into chitosan/PVA edible films, enhancing their functional properties.
- The developed bioactive edible films show potential for sustainable food packaging applications, improving the shelf-life and quality of fresh-cut fruits.
