Protein squid liver powder manufacturers

When sourcing for aquaculture or animal feed, prioritize a Crude Protein content of 45% to 55%. The Crude Fat (Lipid) content should ideally range between 15% and 25%, as squid liver is prized for its high concentration of Omega-3 fatty acids (EPA and DHA). Additionally, ensure the moisture content is below 10% to prevent mold growth and ensure a longer shelf life, and check that the Pepsin Digestibility is above 90% to guarantee efficient nutrient absorption by the target species.

Protein Squid Liver Powder is primarily used as a feeding attractant. You should request a profile of Free Amino Acids, specifically high levels of Alanine, Glycine, and Proline, which stimulate the olfactory systems of fish and shrimp. Furthermore, verify the presence of Nucleotides and Phospholipids, which support immune system enhancement and promote faster growth cycles in intensive farming environments.

As an animal byproduct, this product must adhere to strict sanitary regulations. Ensure the supplier provides a Health Certificate and a Certificate of Origin. For entry into major markets, the facility should be HACCP or ISO 22000 certified. Crucially, request a Heavy Metal Analysis report to ensure levels of Arsenic, Lead, and Mercury fall within the safety limits defined by the destination country's feed regulations (e.g., EU Directive 2002/32/EC).

Inquire whether the supplier uses Low-Temperature Vacuum Drying or Spray Drying techniques. High-heat processing can denature the proteins and oxidize the sensitive fish oils. Low-temperature processing preserves the bioactive peptides and prevents the oil from becoming rancid, which is indicated by a low Peroxide Value (POV) and Acid Value (AV).

Squid liver powder is highly susceptible to oxidation due to its high fat content. You must require the supplier to add Antioxidants (such as Ethoxyquin, BHA, or BHT) during production. Additionally, specify vacuum-sealed packaging or the use of moisture-proof, UV-resistant multi-layer bags (e.g., 25kg PP/PE bags) to maintain stability during transit through tropical climates.

Start by requesting a small sample (1-2kg) for laboratory analysis before committing to a bulk order. When negotiating, leverage volume-based pricing; for instance, a Full Container Load (FCL) typically commands a 10-15% discount compared to Less than Container Load (LCL) shipments. Use the Audit Reports available on Made-in-China.com to verify the supplier's production capacity and export history to ensure they can handle large-scale, consistent supply.

To ensure payment security, utilize Secured Trading Services offered by the platform. For large contracts, consider Letter of Credit (L/C) or Telegraphic Transfer (T/T) with a 30% deposit and 70% balance against the Bill of Lading (B/L). Always insist on a Pre-shipment Inspection (PSI) by a third party like SGS or Intertek to verify that the protein content and weight match the proforma invoice.

Before shipping, confirm that the supplier's factory is registered with your country's Ministry of Agriculture or equivalent body. Failure to do so can lead to customs seizure or mandatory destruction of the goods. Choose CIF (Cost, Insurance, and Freight) terms if you want the supplier to handle the complexities of international shipping, but ensure the Insurance Policy covers 'All Risks' including spoilage due to vessel delays.
