Salmon Milt Powder

Spray-dried hydrolysate of salmon milt (soft roe), naturally rich in DNA-derived nucleotides, protamine peptides, and free amino acids. A premium palatability and immune-functional ingredient for high-value cat and dog formulations, particularly fish-based and limited-ingredient diets.

Off-white to light cream powder with a characteristic mild marine aroma. Standard total nucleotide content of 8 to 15 percent on a dry basis, well above the levels achievable by other natural sources.

We supply pet-grade Salmon Milt Powder from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production. Wild-caught Pacific salmon and farmed Atlantic salmon sources available, with full traceability documentation.

Common market grades include standard hydrolyzed salmon milt powder at 60 to 70 percent protein and 8 to 12 percent nucleotides, high-nucleotide concentrated grade at 15 percent minimum nucleotides for premium cat food positioning, and low-sodium variants for senior-pet and renal-support formulations.

Bulk and reduced-MOQ shipments. Batch-level COA covering protein, nucleotide composition, moisture, fat, sodium, heavy metals, and microbiology, with chain-of-custody documentation to vessel or farm of origin.

Salmon milt is the soft roe (sperm sac) recovered from male salmon during commercial processing. Historically a low-value byproduct, salmon milt is now recognized as one of the densest natural sources of nucleic acids accessible at industrial scale, and is processed into a high-value pet-food and human nutraceutical ingredient.

The nucleic acid fraction (DNA, RNA, and their hydrolysis products) is the functional core of the ingredient. Free and bound nucleotides serve two roles in companion-animal nutrition: they are extremely potent palatants in cats (which detect nucleotide-derived ribose and inosinate at low thresholds), and they are conditionally essential nutrients during periods of rapid cell turnover such as growth, lactation, and recovery from illness or surgery.

Industrial processing proceeds by enzymatic hydrolysis of the milt tissue, separation of the nucleic-acid-rich fraction, and spray drying. Premium-grade material is processed within hours of catch to limit oxidative damage and microbial deterioration of the labile nucleotide fraction.

Regulatory status in pet food is well-established under AAFCO category for processed animal protein and salmon-derived ingredients in North America, and under corresponding categories in the EU, UK, Japan, Australia, and New Zealand. Marine traceability and chain-of-custody documentation are increasingly required by major premium pet-food brands.

• Premium dry and wet cat food palatability enhancement; nucleotide-driven palatability is particularly strong in cats
• Fish-based limited-ingredient diets (LID) for dogs and cats with poultry or red-meat allergies
• Kitten growth and weaning formulas; nucleotides support enterocyte turnover and immune system maturation
• Senior cat and senior dog immune-support functional diets
• Premium freeze-dried, raw-coated, and air-dried pet food formats where marine-source ingredients command premium positioning
• Specialty cat treats and high-value functional cat snacks
• Veterinary recovery and convalescence diets where palatability and immune support are both critical
• Aquaculture and ornamental fish premium feeds (cross-application from the same supply base)
