What Is Porcine Spleen Peptide Powder?
Porcine Spleen Peptide Powder is a hydrolyzed animal protein ingredient made from fresh, healthy pig spleen tissue. The spleen is cleaned, homogenized, defatted, and treated with selected proteases. This process breaks larger proteins into shorter peptide chains that are easier to disperse and digest.
The standard grade contains at least 65% peptides and 75% protein on a dry basis. At least 85% of its peptides have a relative molecular weight below 500 Da. The finished ingredient is normally a white to light-yellow, free-flowing powder with a mild characteristic taste.
Other Names
Common commercial names include:
Porcine spleen peptides, pork spleen peptide powder, swine spleen peptide powder, porcine spleen hydrolysate, hydrolyzed pork spleen powder, porcine spleen protein hydrolysate, spleen oligopeptide powder, and pork organ peptide powder.
CAS Number and Molecular Information
Porcine spleen peptide powder is a natural mixture rather than a single chemical compound. It does not have one fixed CAS number, molecular formula, or molecular weight. Its main components are short peptide chains and amino acids produced from porcine spleen proteins.
The peptide fraction is mainly standardized by total peptide content and molecular weight distribution. Custom 80-mesh powder can be supplied for capsule, tablet, drink-mix, and sachet manufacturing.
Solubility and Stability
The powder disperses in water and normally produces a light-colored solution. Trace white peptide particles may remain at approximately pH 5.4 to 6.0. The ingredient is stable between pH 4.0 and 9.0. It can withstand heating at 100°C for 30 minutes or 121°C for 20 minutes under the conditions stated in the product specification.
Unicorns Biotechnology can adjust peptide content, protein level, particle size, bulk density, flavor profile, and packaging for different formulations.
Key Peptide and Nutrient Profile
Porcine spleen peptide powder is standardized mainly by its peptide and protein content. The balance consists of moisture, mineral ash, free amino acids, and minor nutrients naturally present in spleen tissue.
Small-Molecule Peptides
The main active fraction consists of oligopeptides formed through controlled enzymatic hydrolysis. The standard export grade contains at least 65% peptides, with at least 85% of the peptide fraction below 500 Da.
These short chains require less digestive breakdown than intact spleen protein. This makes them suitable for drink powders, capsules, and nutrition formulas designed for rapid dispersion and easy digestion.
Protein and Amino Acids
Total protein is standardized at not less than 75% on a dry basis. A separate food-grade profile can be produced with protein at or above 80%, depending on the agreed specification.
The protein hydrolysate supplies a range of amino acids and short peptide chains. The exact amino acid profile can be tested for product development or label support.
Naturally Occurring Micronutrients
Porcine spleen tissue may contain iron, vitamin B12, minerals, and other minor nutrients. These components are not automatically standardized in every batch. Buyers planning iron, vitamin, or mineral claims should request batch-specific testing before preparing finished-product labels.
Porcine Spleen Peptide Powder Specifications
Unicorns Biotechnology supplies a high-peptide export grade with protein ≥75%, peptides ≥65%, and at least 85% of peptides below 500 Da. Moisture is controlled at ≤7.0%, while ash is limited to ≤9.0%.
A separate profile based on the Q/BCKZ 0128S-2024 solid beverage standard can use protein ≥80%, oligopeptides ≥55%, moisture ≤5.0%, and lead ≤0.9 mg/kg. The standard also sets microbiological limits for total plate count, coliforms, mold, and Salmonella.
The production process is water-based and uses food-grade protease rather than routine organic solvent extraction. Residual solvent testing can still be arranged when required. Each shipment can include a batch COA, SDS or MSDS, manufacturing flow chart, country-of-origin statement, allergen statement, porcine-origin declaration, and third-party laboratory report.

Porcine Spleen Peptide vs Bovine Spleen Peptide
Porcine and bovine spleen peptides are both animal-derived protein hydrolysates, but they come from different species. Their peptide profiles, taste, color, sourcing costs, and regulatory acceptance may differ.
| Comparison | Porcine Spleen Peptide | Bovine Spleen Peptide |
|---|---|---|
| Raw material | Pig spleen | Cattle spleen |
| Common positioning | Daily nutrition and immune-support formulas | Bovine glandular and organ supplement formulas |
| Peptide profile | Depends on enzyme process and molecular weight target | Depends on enzyme process and molecular weight target |
| Religious suitability | Not suitable for Halal or Kosher products | May qualify when sourcing and certification meet requirements |
| BSE and TSE concern | Lower relevance for porcine species | Requires clear bovine origin and TSE/BSE documentation |
| Selection basis | Species preference, specification, cost, and market rules | Species preference, specification, certification, and market rules |
There is no universal basis for claiming that one species is always more active than the other. Buyers should compare peptide content, molecular weight distribution, source traceability, microbiological quality, and finished-product requirements.
Potential Benefits and Formulation Value
Porcine spleen peptide powder is mainly used as an easily dispersed source of animal-derived peptides and protein. Finished-product benefits depend on the complete formula, serving size, clinical support, and permitted claims in the target market.
Easily Digested Peptide Nutrition
Enzymatic hydrolysis breaks intact spleen proteins into shorter chains. These peptides require less digestive processing than whole organ powder and may be more suitable for users who prefer hydrolyzed protein ingredients.
Immune-Nutrition Formulations
Spleen-derived ingredients are commonly used in products positioned for immune nutrition and general resistance support. The ingredient can be combined with colostrum, thymus peptides, zinc, vitamin C, beta-glucans, or amino acids.
Any immune-related claim should be based on the finished formula and local regulatory requirements. The raw material should not be presented as a treatment for infection or immune disease.
Recovery and Nutritional Support
The powder provides protein, peptides, and amino acids in a concentrated form. It can be used in nutrition products aimed at adults with increased protein needs, limited appetite, or recovery-related dietary requirements.
Use in medical foods, hospital nutrition, or post-surgery formulas requires local approval and review by qualified healthcare professionals.
Antioxidant and Cellular Nutrition Research
Some animal protein hydrolysates contain peptide sequences studied for antioxidant activity. The level of activity depends on the enzyme, peptide sequence, molecular weight distribution, and laboratory method.
Buyers developing antioxidant products can request peptide profiling, amino acid testing, or application-specific laboratory analysis.
Porcine Spleen Peptide Manufacturing Process
Production starts with inspected, fresh porcine spleen. The tissue is trimmed to remove membranes and unwanted material, washed, crushed, and mixed with purified water to form a uniform slurry.
The slurry undergoes low-temperature homogenization and controlled degreasing. Selected food-grade proteases are then added under controlled pH, temperature, and time conditions. After hydrolysis, the enzymes are inactivated and the liquid is filtered to remove insoluble material.
The peptide solution is concentrated, dried, milled, sieved, and blended. Each batch is then tested for protein, peptide content, molecular weight distribution, moisture, ash, heavy metals, and microbiological quality before packing. This general sequence follows the process described in the attached enterprise standard: crushing, membrane removal, slurrying, enzymatic hydrolysis, filtration, concentration, drying, milling, blending, and packaging.
Porcine Spleen Peptide Powder Applications
Its high protein content, small peptide size, and water dispersibility allow it to fit several human and animal nutrition formats. Formulators should consider taste masking, porcine-origin labeling, dosage, and local regulatory status during product development.
