We specialize in the R&D and large-scale production of aquatic animal and plant protein peptide ingredients, with a core focus on supplying high-quality oyster peptide powder. Derived from fresh deep-sea oysters, our product is manufactured using a modern process-including enzymatic hydrolysis, separation and purification, and spray drying-to yield a low-molecular-weight oyster oligopeptide powder. We ensure a controllable supply chain and adhere to food-grade clean production standards throughout the manufacturing process. The finished product is a fine white powder featuring excellent solubility and low molecular weight, making it highly compatible with formulations for tablets, capsules, solid beverages, and nutritional powders. We seek long-term partnerships with global dietary supplement manufacturers, food processors, and overseas traders, offering support for everything from small sample orders to bulk purchases. We provide batch-specific Certificates of Analysis (COA) and microbiological test reports, as well as customized neutral English packaging for export, striving to be a stable and reliable long-term supplier of aquatic peptide ingredients for international markets.
Our product is free from fillers, colorants, and preservatives; it appears as a uniform pale yellow powder with consistent quality across batches. It is widely used in formulations for functional solid beverages, nutritional capsules, tablets, and various dietary supplements. We maintain ample year-round stock and offer bulk repackaging and customization services, supplying global ingredient wholesalers, health product manufacturers, and brand owners.

Comprehensive Production Process and Quality Advantages
We employ a closed-loop production model spanning the entire chain-from raw material selection to final product shipment-strictly controlling every production step to ensure product stability and safety. This creates a core competitive advantage that sets us apart from industry peers:
Rigorous Raw Material Selection
We source high-quality, fresh oysters from unpolluted marine farming zones, discarding dead or diseased oysters and spoiled frozen stock to ensure the natural bioactivity and nutritional purity of the raw materials right from the source.
Precision Enzymatic Hydrolysis & Three-Stage Ultrafiltration Purification
We utilize targeted enzymatic hydrolysis with composite biological proteases to precisely break down large-molecule proteins into easily absorbed small-molecule peptides. A three-stage ultrafiltration process removes macromolecular impurities, residual proteins, and insoluble matter, significantly enhancing product purity and bioactivity.
Low-Temperature Controlled Drying
We use a low-temperature spray-drying process to prevent high-heat damage to bioactive substances, fully preserving the taurine, trace elements, and bioactive peptides found in oysters, thereby maximizing the product's nutritional value.
Batch-by-Batch Testing and Quality Control
Every batch undergoes testing for heavy metals, microorganisms, active ingredient content, and residues. Our products meet international food safety standards for export and are verified through testing by authoritative third-party institutions.
Core Product Features and Competitive Advantages
Small-molecule oligopeptides require no further breakdown by the body and can be directly absorbed and utilized by the intestines. Their absorption efficiency is three times that of standard oyster powder and five times that of pure protein, offering superior biological activity and more efficient nutritional supplementation.
Naturally high levels of organic zinc, selenium, and taurine are combined with 18 essential amino acids. All nutrients exist in a peptide-bound state, ensuring better absorption and utilization by the body compared to supplements containing isolated trace elements.
The pure powder features a fine, uniform texture and no off-flavors; it is completely water-soluble with no sedimentation or separation. It is compatible with various manufacturing processes and ideal for use in tablets, capsules, single-serve powder sachets, functional beverages, and oral liquids, without altering the appearance or taste of the finished product.
Free from preservatives, colorants, and chemical additives, the product meets heavy metal safety standards. It is gentle and non-irritating, suitable for producing a wide range of functional nutritional foods and compliant with global regulations for health supplements.
Customizable specifications are available, ranging from 50% to 98% peptide purity and various molecular weights. The product offers consistent color and activity levels across batches, a long shelf life, and high stability against moisture-induced clumping or spoilage.
