| Protein and Composition | Protein content, moisture, ash, pH, solubility, and other parameters relevant to product functionality. | Certificate of analysis supported by validated laboratory methods such as nitrogen-based protein analysis, gravimetric moisture, ash testing, and pH measurement. | Use a written product specification; a common buyer-defined example is protein at or above 90% on a dry basis for hydrolyzed collagen, subject to product type and method. | Every lot or statistically justified sampling plan | Inconsistent potency, poor processing performance, and formulation failure |
| Microbiological Safety | Total aerobic count, yeast and mold, specified pathogens, and indicator organisms relevant to the product and process. | Accredited-laboratory testing using recognized microbiological methods; review of environmental-monitoring and heat-treatment records. | Pathogens such as Salmonella must be absent where required by applicable food law; other limits must follow the destination-market specification. | Every lot for high-risk applications, otherwise risk-based | Foodborne illness, spoilage, and product recall |
| Heavy Metals and Elemental Contaminants | Lead, arsenic, cadmium, mercury, and other elements relevant to the source, process, and intended use. | Inductively coupled plasma mass spectrometry or another validated elemental method performed by a competent laboratory. | Each result must comply with the legally applicable maximum levels for the destination market and product category. | Every lot initially; then risk-based with periodic verification | Chronic toxicity, regulatory noncompliance, and market withdrawal |
| Chemical Contaminants | Residual solvents, processing aids, veterinary-drug residues, pesticides, dioxins, PCBs, and other source-specific contaminants. | Risk-based contaminant plan, supplier declarations, targeted LC-MS/MS or GC-MS testing, and review of source-water or marine-environment data when relevant. | Testing scope must reflect species, geography, processing chemistry, and destination-market legal limits. | At qualification and periodically according to risk | Undeclared contamination and legal nonconformity |
| Allergen and Cross-Contact Control | Potential contact with milk, soy, wheat, fish, crustaceans, sesame, or other regulated allergens at the manufacturing site. | Allergen map, cleaning validation, production-sequence controls, label declaration, and targeted allergen testing where justified. | All intentionally present allergens must be declared according to destination-market law; unintended cross-contact must be controlled and documented. | At qualification and after process or site changes | Allergic reaction, undeclared-allergen recall, and labeling violation |
| Processing and Hydrolysis Control | Acid or enzyme treatment, hydrolysis conditions, filtration, drying, temperature controls, and prevention of recontamination. | Process flow diagram, critical-control-point records, validation studies, batch manufacturing record, and change-control history. | Critical process parameters must be defined, monitored, recorded, and linked to the released lot. | At approval and during each supplier audit | Variable peptide profile, contamination, and inconsistent functional performance |
| Functional Performance | Solubility, dispersibility, taste and odor, bulk density, molecular-weight distribution, and compatibility with the intended formulation. | Standardized bench testing under defined pH, temperature, concentration, and mixing conditions; sensory and application trials. | Results must remain within the agreed specification and demonstrate suitability for the finished product process. | Each lot for critical applications; otherwise periodic verification | Poor consumer experience, sedimentation, processing loss, or rejected production batches |
| Stability and Shelf Life | Stability under intended storage conditions, packaging protection, water activity, moisture pickup, and expiry dating. | Real-time and accelerated stability data, packaging specification, water-activity testing, and transport-condition assessment. | Shelf life must be supported by data, with storage conditions and expiry dates clearly stated on the specification and label. | At qualification and whenever formulation or packaging changes | Caking, loss of functionality, off-odor, or premature expiry |
| Laboratory Competence | Whether analytical results are generated by a competent internal or external laboratory using fit-for-purpose methods. | Laboratory accreditation status, method validation or verification, proficiency-testing records, sampling plan, and chain-of-custody documentation. | Critical safety tests should be performed by a competent laboratory using validated and documented methods. | At qualification and during periodic supplier audits | False confidence caused by unreliable or non-comparable results |
