Hypothesis
The collagen extraction yield from lumpfish skin could be improved beyond previously reported values of 14–40%.
Conclusion
The study developed a protocol that achieved collagen yields up to 60% from lumpfish skins, significantly improving previous extraction methods.
Supporting Evidence
- The study achieved collagen yields of up to 60%, which is higher than previously reported.
- Optimized conditions included a 0.9 M acetic acid concentration and a 36-hour extraction time.
- Enzyme hydrolysis added an additional 23% yield to the collagen extraction process.
Takeaway
This study found a way to get more collagen from fish skins, which can be used in food and beauty products.
Methodology
The study used a full factorial design to optimize pre-treatment with NaOH and a Box–Behnken design for acid extraction.
Limitations
The study was limited to lumpfish skins and may not be applicable to other fish species.
