Oyster Peptide Powder

Advanced Purification Technology: Shaanxi Rebecca Biotechnology Co., Ltd. uses segmented enzymatic hydrolysis and electrodialysis and chelating resin systems to eliminate the dangers of heavy metals in shellfish raw materials. This two-step elimination means your compositions can meet tough export safety criteria.

Tailored Deodorisation Methods: Traditional oyster powders suffer from heavy fishy odours that adversely affect the palatability of products. Our selective resin deodorisation method not only removes offensive odours, but maintains the natural marine essence, with the level of odour adjustable to your particular formulation needs.

OEM / ODM Services: Adaptability From powder blends to pills, hard capsules and even soft gels, we offer full customisation from dosage forms to packaging design. Our robust supply chain and effective logistics network ensure fast delivery worldwide.

Quality Assurance: 100% transparent, each batch is tested by an independent 3rd party and comes with full GPC molecular weight distribution data, peptide content verification and free amino acid ratio analysis. We supply full raw material quarantine documentation and batch traceability records for factory audit.

Competitive Advantages: Review free samples. The internal quality controls are high and above industry norms. Our innovative high-temperature drying and ultra-fine grinding technique ensures optimal nutritional integrity and bioactivity.

The meat of raw oysters is thoroughly washed to remove any gills, viscera and shells before high pressure homogenisation. The surface oils are removed by treatment with lipase at low temperature to prevent rancidity. Then the pretreated material is subjected to segmental enzymatic hydrolysis in which neutral protease, flavour protease and aminopeptidase act sequentially under exact temperature and pH control. Online monitoring guarantees the correct degree of hydrolysis before enzyme deactivation at 85℃ in an effort to minimise over-hydrolysis to free amino acids.

Centrifugation (plate and frame) to eliminate insoluble residues and provide clear enzymatic supernatant Multi-stage membrane separation: Ultrafiltration to remove big proteins Nanofiltration for concentration and molecular weight fractionation. Electrodialysis eliminates ionic heavy metals. Chelating resin adsorbs trace cadmium and lead in depth. Shellfish contamination worries are thoroughly solved.

Specialised adsorption resin targets volatile fishy chemicals in deodorisation, and low-temperature activated carbon fine-tunes colour without damaging peptide integrity. The concentrated liquid is evaporated under vacuum at low temperature (≤55℃) and light-proof conditions, to avoid oxidation and deterioration. Spray drying can yield either fine powder or free-flowing granules, depending on application needs. Final sifting, three-dimensional batch blending and vacuum-sealed packaging in light-proof aluminium foil bags provide constant quality and a longer shelf life.

Standard Packaging: Oyster Peptide Powder is packaged in double-layer protection featuring vacuum-sealed aluminum foil inner bags to prevent moisture and light exposure, enclosed in moisture-proof cardboard drums for physical protection during transit. The standard packaging sizes are 1kg, 5kg, 10kg and 25kg. Custom package specs available on request to suit automated manufacturing line feeding requirements or unique branding requirements.

Bulk Orders: For large-volume orders, we offer specialized industrial packaging in fiber drums with reinforced structures suitable for container shipping. All packages are strictly checked for sealing integrity before warehousing.

Delivery Options: We work with the world’s top logistics companies like FedEx and DHL to provide swift air shipping. For urgent orders we can send express air which takes 5-7 business days. Sea freight is offered as well for economical bulk shipment. Both full container loads (FCL) and less than container loads (LCL) are accessible. Our logistics team manages customs documents and compliance standards for seamless cross-border delivery. All shipments are tracked in real time and we have full insurance coverage in route.

Q: Can you verify true peptide content versus free amino acids?

A: Yes. We simultaneously test actual peptide content and free amino acid proportion. GPC molecular weight distribution chromatograms are provided, demonstrating that most components are bioactive small peptides rather than single amino acids.

Q: How do you control fishy odor in formulations?

A: Our selective adsorption resin technology removes pungent fishy smells while retaining natural oyster flavor. Customized deodorization grades are available based on your specific formulation requirements.

Q: What raw material quality controls do you implement?

A: Only edible oyster flesh is used, with gills, viscera, and shells completely removed. Aquatic inspection certificates and full production batch records are available for third-party audit and factory inspection.
