Hypothesis
The study aims to evaluate how the release of fatty acids from marine oils during digestion is influenced by their esterification form and encapsulation.
Conclusion
The source of marine oil and its encapsulation significantly impact the bioaccessibility of fatty acids, which likely modulates their effectiveness.
Supporting Evidence
- The release of free fatty acids after simulated digestion mainly depends on the oil source.
- Calanus oils showed the lowest free fatty acid release due to high amounts of wax esters.
- Encapsulation can modulate the absorption and blood concentration of n-3 LC-PUFAs.
- Different lipid classes in oils influence their bioaccessibility during digestion.
Takeaway
This study looks at how well our bodies can absorb fatty acids from different types of fish oil supplements, showing that some oils are easier to digest than others.
Methodology
The study used in vitro digestion methods and two analytical techniques, TLC-FID and 1H-NMR spectroscopy, to evaluate fatty acid release from different marine oil supplements.
Limitations
The study did not include gastric lipase in the digestion protocol, which may affect the bioaccessibility results.
