Circular Economy and Sustainability
- Marine byproducts that would otherwise be discarded are used by FPHs to create value.
- By turning low-value streams into high-value nutritional components, they embody the circular economy model.
The Journal of Aquatic Food Product Technology (2024) published a comprehensive analysis of fish protein hydrolysates (FPHs), which are made from marine by-products. Despite not introducing novel protein sources, the research provides an in-depth analysis of production processes, biological actions, and formulation guidelines that are pertinent to pet diets that are sustainable, hypoallergenic, and beneficial to the gut.
Fish Protein Hydrolysates (FPHs): Functional Boost for Pet Nutrition

Significant Scientific Findings
Methods for Enzyme and Production
- Fish processing waste—bones, skin, viscera, and scales—is frequently treated enzymatically using enzymes such as Alcalase, papain, or proteases to make FPHs.
- This enzymatic approach is superior to chemical hydrolysis because it allows for exact control over peptide size and results in superior nutritional and functional qualities.
Advantages that are Bioactive and Functional
- Antioxidant Activity: Peptides obtained from FPH neutralize free radicals, which aids in lowering oxidative stress in animals.
- Anti-Inflammatory Effects: Cell investigations have shown that peptides can inhibit the expression of COX 2, TNF α, and interleukin.
- Antimicrobial activity and gut support: FPHs can help foster a balanced microbiome and fight harmful bacteria.
Nutritional Value & Digestibility
- FPHs are a superior protein source with a comprehensive amino acid profile.
- They are easily digestible because of their tiny peptide composition, making them a perfect match for diets for pets with allergies or other sensitivities.

The following actions for manufacturers:
- Planning for production and resources
Collaborate with processors or fisheries to obtain fish by-products and collaborate with enzyme specialists to maximize hydrolysis.
- Operational Pilot Testing
Carry out brief feeding trials with the goal of evaluating antioxidant and gut health results, notably in animals suffering from allergies or IBD.
- Verify Label Claims
Use in vivo markers and analytical tests such DPPH/FRAP to back up assertions about antioxidant or anti-inflammatory health.
- Make sure that all regulations are followed.
Ensure that ingredient claims comply with FEDIAF/AFFCO requirements and gather supporting data for functional advantages.
- Strategic Product Positioning
Advertise as a component of “limited ingredient,” “hypoallergenic,” or “functional nutrition” product lines, emphasizing MAP labeling and sustainability.
- Managing the Supply Chain
Uphold quality and traceability across procurement and manufacturing while adhering to environmentally responsible sourcing procedures.
Conclusion
Scientifically supported benefits of fish protein hydrolysates (FPHs) for pet food include sustainably credentials, a low risk of allergies, antioxidant and anti-inflammatory properties, and proteins that are easily absorbed. Although not a novel protein source, FPHs are a viable, circular alternative for pet food formulators who prioritize health and environmental innovation.
