Passion fruit (Passiflora edulis Sims) by-products as a source of bioactive compounds for non-communicable disease prevention: extraction methods and mechanisms of action: a systematic review

What if the seeds and rinds you throw away after eating passion fruit could help fight diabetes and heart disease? A new systematic review says yes—and it's all about the hidden powers of nature's waste.

Passion fruit is delicious, but its by-products—the peel, seeds, and pulp residue—are often discarded. Yet these scraps are packed with bioactive compounds that may prevent non-communicable diseases (NCDs) like cardiovascular conditions and diabetes. This systematic review digs into the science behind this potential, asking how we can unlock these benefits and how they work inside our bodies.

The review examines various extraction methods, from solvents to emerging green technologies, to isolate these valuable molecules. It also explores the mechanisms of action—how these compounds interact with our cells to reduce inflammation, oxidative stress, and other disease drivers. The findings suggest that passion fruit by-products are not just waste; they are a promising, sustainable source of health-promoting agents.

For scientists, this is a call to optimize extraction and understand the precise pathways. For the rest of us, it's a reminder that sometimes the best medicine is hidden in what we overlook. The review is a comprehensive map, guiding future research and potential applications in functional foods or supplements.

Key Points

• Passion fruit by-products contain bioactive compounds for NCD prevention.
• Extraction methods and mechanisms of action are systematically reviewed.
• Promising sustainable source for functional foods or supplements.
