Sustainable Valorization of Sour Cherry (Prunus cerasus) By-Products: Extraction of Antioxidant Compounds

What if the cherry you just enjoyed could hold the secret to longer life? The pits and skins left after juicing sour cherries are packed with antioxidants that science is only beginning to unlock.

Sour cherries are a summer favorite, but their processing leaves behind mountains of pomace—skin, flesh, and pits. For years, these by-products were discarded, yet they are far from worthless. In fact, they are treasure troves of phenolic compounds, natural antioxidants with significant implications for human health and longevity.

This review dives into the antioxidant potential of sour cherry pomace and seed oil. Both are rich in bioactive compounds that could serve as ingredients in functional foods. As global sour cherry production rises, so does the opportunity to turn waste into wellness.

The push for sustainability has made industrial fruit by-products more attractive than ever. Researchers have published numerous studies on using cherry skins and pits, but this comprehensive review goes further. It evaluates advanced extraction techniques and identifies the best strategies for scaling up to industrial levels.

The message is clear: what we throw away might be exactly what we need. Sour cherry waste is not a problem—it's a solution waiting to be harnessed.

Key Points

• Sour cherry pomace and seed oil are rich in phenolic antioxidants.
