Sweet cherry byproducts processed by green extraction techniques as a source of bioactive compounds with antiaging properties

Could the stems of sweet cherries, discarded by the food industry, hold the key to youthful skin? A new study says yes—and it's all thanks to green chemistry.

The cosmetic industry is always hunting for the next innovative ingredient, and natural sources are leading the charge. In this study, researchers turned to an unlikely hero: sweet cherry stems, a byproduct of food processing. Using green extraction techniques—pressurized solvent, supercritical CO2, and subcritical water—they created three new extracts from these stems.

Chemical analysis revealed a treasure trove: 57 compounds, mostly flavonoids, along with organic and phenolic acids, fatty acids, and terpenes. But not all extracts were created equal. After a rigorous screening that included antioxidant, enzymatic, and photoprotective tests, one stood out: the extract from supercritical CO2.

This champion extract showed broad antioxidant power, especially against lipid peroxyl and hydroxyl free radicals—the culprits behind cellular aging. It also demonstrated significant photoprotective action, shielding cells from UV damage. With these antiaging properties, it emerges as a promising candidate for future cosmetic formulations.

This isn't just about beauty; it's about sustainability. By turning waste into value, we may soon see skincare products that are both effective and eco-friendly—a win for science, industry, and the planet.

Key Points

• Green extraction from cherry stems yields 57 bioactive compounds.
• Supercritical CO2 extract shows strong antioxidant and photoprotective action.
• Potential new antiaging ingredient for sustainable cosmetics.
