Spondias tuberosa Seed as a Source of Bioactives by an Optimized Microwave-Assisted Green Extraction

Did you know that the seed of a humble Brazilian fruit could be the next big thing in eco-friendly cosmetics? A new study shows how microwave-assisted extraction turns this waste into a treasure trove of bioactive compounds.

In the arid landscapes of Brazil's Caatinga, the umbu fruit thrives, but its pulp is the star—leaving the seeds as overlooked waste. Now, researchers have found a way to turn those seeds into a valuable resource. By using propylene glycol, a green solvent, and microwave-assisted extraction, they unlocked a wealth of phenolic compounds from the seeds, which are known for their antioxidant powers.

Key Points

• Umbu seeds are 25% of processing waste.
• Optimized extraction boosts phenolic content by 41%.
• Extract shows SPF 13 and no toxicity in tests.
