From Nutritional Profile to Circular Bioeconomy: A Review of Sea Buckthorn Oil and By-Product Valorization

Did you know that a single plant can produce two distinctly different oils, each with its own health-boosting powers? Sea buckthorn is nature's hidden pharmacy, and its by-products are the next frontier in sustainable industry.

Sea buckthorn is not just a berry; it's a botanical powerhouse. Its seeds and pulp yield two distinct oils, each with a unique chemical fingerprint. Seed oil is loaded with polyunsaturated fats, tocopherols, and phytosterols, while pulp oil shines with palmitoleic acid and carotenoids. These differences translate into a range of bioactivities, from antioxidant and anti-inflammatory effects to lipid regulation.

But the story doesn't end with the oil. The by-products—rich in polyphenols and fiber—are gaining attention as valuable resources. Instead of waste, they offer a chance to boost resource efficiency and sustainability. This aligns with the principles of a circular bioeconomy, where every part of the plant is put to good use.

However, most evidence comes from lab studies, not human trials. We still need clarity on how these compounds work in the body, their bioavailability, and proper dosing. Future research and green extraction technologies could unlock the full potential of sea buckthorn, making it a cornerstone of sustainable health and industry.

Key Points

• Sea buckthorn yields two distinct oils with different bioactives
• By-products rich in polyphenols and fiber boost sustainability
• Evidence mostly from lab studies; clinical research needed
