Exploring the potential of antioxidants from fruits and vegetables and strategies for their recovery

Eating five servings of fruits and vegetables a day does more than just fill your plate—it is a cornerstone of human health and disease prevention.

Fruits and vegetables are nutritional powerhouses packed with essential vitamins, minerals, fiber, and powerful antioxidants. A balanced diet rich in these plant-based foods strengthens the immune system and actively helps prevent conditions like diabetes, obesity, heart disease, and certain cancers. When our bodies suffer from oxidative stress due to an imbalance between free radicals and natural defenses, these antioxidants step up as vital defenders.

Researchers have conducted an exhaustive review focusing on the bioactive antioxidant compounds found in Spain's most widely produced fruits and vegetables, linking their chemical profiles directly to human health. But the innovation does not stop at consumption. Scientists are also looking at how to recover these valuable compounds from fruit and processing waste streams, driving the goals of a circular economy.

Extracting these treasures sustainably requires modern approaches. Green extraction technologies—particularly microwave-assisted and ultrasound-assisted methods—prove remarkably efficient. They deliver high yields comparable to traditional techniques while maintaining gentler operating conditions, alongside promising results from enzyme cocktails and pulsed electric fields.

Key Points

• Fruits and vegetables provide essential antioxidants for disease prevention.
• Review analyzes bioactive compounds in Spain's top produced crops.
• Green technologies like microwaves efficiently recover antioxidants from food waste.
