Bulk Fish Processing Enzymes for Industry

We supply alkaline protease, lipase, phytase, beta-glucanase, and cellulase — for both fish processing and aquaculture feed applications. Activity certificates and TDS provided. Custom enzyme blends for feed formulation available.

Standard FPH process: (1) Mince fish material, adjust pH to 7.5–9.0 with NaOH, (2) Heat to 45–55°C, (3) Add alkaline protease at 0.1–0.5% w/w, (4) Hydrolyze 2–6 hours with stirring until target degree of hydrolysis (DH 50–80%), (5) Inactivate enzyme at 85°C for 15 min, (6) Centrifuge to remove undissolved solids, (7) Spray dry or concentrate liquid. Monitor DH with OPA method or pH-stat.

Yes — significantly. Traditional fish sauce fermentation relies on endogenous fish autolytic enzymes and microorganisms over 12–18 months. Adding exogenous alkaline protease (0.1–0.3% w/w fish) at 45–55°C can achieve equivalent degree of hydrolysis in 2–4 weeks. The resulting hydrolyzate then undergoes a shorter fermentation period for flavor development. This is the method used in industrial fish sauce production in Thailand, Vietnam, and the Philippines.

Adding phytase at 500–1,000 FTU/kg feed reduces the required supplemental inorganic phosphorus (dicalcium phosphate) by 30–60%, depending on the phytate content of the diet and the phosphorus requirement of the species. For a salmon grower diet with 60% plant inclusion, this represents a saving of 3–5 kg dicalcium phosphate per tonne of feed. Phytase also releases bound protein and energy, improving overall feed utilization by ~3–5%.

Yes — multi-enzyme blends are common in commercial aquafeed. The three enzyme classes (phytase, beta-glucanase, cellulase) target different substrates and do not interfere with each other. We can formulate custom multi-enzyme preparations at specific activity ratios for your diet composition. Key consideration: phytase activity is heat-sensitive above 70°C, so add either a thermostable variant, coat post-pellet, or reduce conditioner temperature.

Yes. Each product has a TDS specifying activity (U/g, FTU/kg), temperature and pH optimum, recommended dosage, and shelf life. CoA issued per batch. We provide documentation for aquaculture certification schemes (ASC, BAP, GlobalGAP) on request.

MOQ is 1 kg for enzyme powders. For aquafeed premix applications, we supply 25 kg bags. Custom blends start at 5 kg. We supply fish processors, aquafeed manufacturers, and aquaculture operations globally.

Store enzyme powders at ≤25°C in sealed packaging, away from moisture and direct sunlight. Shelf life: 12–24 months. For aquafeed applications, add enzymes to dry premix (not to hot water or steam) and mix thoroughly before incorporating into the main batch. Liquid enzyme concentrates: store at 2–8°C, shelf life 12–18 months.

Powder enzymes: 12–24 months at ≤25°C, sealed packaging. Liquid enzymes: 12–18 months at 2–8°C. Phytase has moderate thermostability — thermostable variants survive pelleting at up to 85°C. Full shelf life and stability data on each TDS.

Yes. We formulate multi-enzyme blends combining phytase, beta-glucanase, cellulase, and xylanase at activity ratios matched to your specific diet composition and target species. We can also blend with phytase coating technology for pelleting stability. MOQ 5 kg, lead time 2–4 weeks. Technical support included.
