Tuna Collagen Peptide - Deep-Water Marine Source with Low-Fat, High-Purity Profile

Tuna is a deep-water, high-activity fish whose skin collagen is valued for its low fat content and high peptide purity. Our Tuna Collagen Peptide is produced from tuna skin through controlled enzymatic hydrolysis, with additional defatting steps that produce a peptide with exceptionally low residual lipid content. This makes it particularly suitable for formulations where fat oxidation and off-flavor development are concerns - such as long-shelf-life powders and ready-to-mix beverage blends.

We know that for brands selling into the sports-nutrition and active-lifestyle market, a clean label and a pure ingredient profile matter. Tuna collagen's low-fat profile means fewer antioxidants needed in your formulation, a longer stable shelf life for the finished product, and a cleaner ingredient declaration. Every lot is tested for residual fat and peroxide value to confirm the low-fat specification.

Why Tuna Collagen Stands Out for Clean-Label and Sports Nutrition

Low residual fat for extended shelf stability

Additional defatting during processing produces a peptide with minimal residual lipid content. This reduces the risk of fat oxidation and rancidity in finished powders, extending the stable shelf life of your product and reducing the need for antioxidant additives in your formulation.

Deep-water source, high purity perception

Tuna is a deep-water, pelagic fish that consumers associate with clean, open-ocean sourcing. This supports marketing narratives around purity and natural origin, particularly in sports-nutrition and active-lifestyle product categories.

High protein yield per kilogram

Tuna skin has a high collagen content relative to total tissue weight, which translates to a high protein yield in the finished peptide. For formulators calculating cost per gram of protein, this can improve the economics of your finished product.

Low odor through advanced processing

The combination of low raw-material fat content and our multi-stage deodorization produces a peptide with minimal fishy odor - important for products where the consumer opens the container and smells the powder directly, such as tub-format protein powders.

Target Applications and Formulation Fit

Tuna Collagen Peptide is well suited for sports-nutrition products: post-workout recovery powders, protein blends targeting muscle and connective tissue, active-lifestyle collagen supplements, and functional foods for fitness consumers. Its low-fat profile also makes it a strong candidate for long-shelf-life stick packs and sachet formats where oxidation stability is critical.

Processing note: the peptide blends well with whey protein, plant proteins, and amino acid blends common in sports nutrition. It dissolves readily in shaker-bottle conditions with minimal foaming. For ready-to-drink sports beverages, we recommend standard homogenization and pasteurization conditions. The low fat content means the finished beverage has better clarity and less ring formation during storage.

Bulk Supply, Packaging, and Shipping for Ingredient Buyers

Thanks to its stable dry-powder form, collagen peptide ships as a standard dry good - no cold chain needed, and landed costs remain fully predictable. In-stock grades turn around quickly, while custom-formulation batches run on a standard production timeline. A dedicated safety stock of our fastest-moving grades is always maintained to support rush orders. Full shelf-life and storage details are provided on the Certificate of Analysis and product label.label.

Questions Procurement Teams Ask Us

Q: Can peptides be used in cosmetic formula?

A: Yes, our high-purity peptides are widely applicable for skincare and cosmetic raw material formulas.

Q: Will peptides fade or change color after dissolution?

A: No obvious discoloration occurs under normal storage and usage conditions, with stable solution state.

Q: Can food-grade peptide be directly added into high-temperature sterilization process?

A: Short-time high-temperature sterilization is acceptable. Long-time high-temperature heating will lead to peptide degradation, reducing active peptide content.

Q: What peptide products do you offer?

A: We supply food-grade and medical-grade animal and plant peptides, including fish collagen, soybean, corn and wheat peptides for food, health care and pharmaceutical manufacturers.

Q: Do you offer price adjustment for long-term bulk contracts?

A: We provide preferential fixed pricing and seasonal price protection for long-term contractual clients.
