Bonito Elastin Peptide
Bonito Elastin Peptide is a low molecular weight hydrolysate of elastin protein recovered from the bulbus arteriosus and arterial tissue of skipjack tuna, Katsuwonus pelamis, commonly traded under the Japanese name katsuo.
The ingredient is distinct from fish collagen. Elastin is the rubber-like structural protein responsible for the recoil of arteries, lung tissue, ligaments, and skin, and bonito provides one of the few commercially viable marine sources.
We source bulk Bonito Elastin Peptide from top China manufacturers for our partners. The manufacturers are in Shandong and Guangdong. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Bonito Elastin Peptide is graded by elastin purity, peptide molecular weight, and the level of the signature crosslink amino acids desmosine and isodesmosine.
Standard supplement grade typically delivers 90 percent or higher protein content with desmosine and isodesmosine combined at around 500 to 1000 micrograms per gram. Average peptide molecular weight sits between 1000 and 3000 Daltons.
Premium grades push molecular weight below 1000 Daltons and report desmosine content above 1000 micrograms per gram, which suppliers use as a marker of true elastin origin rather than a generic fish protein hydrolysate.
Cosmetic grades are usually dried at higher concentration and may be sold in liquid form for direct incorporation into essences and serums.

How We Help Source Bonito Elastin Peptide
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Bonito Elastin Peptide out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Bonito Elastin Peptide together with other ingredients such as Collagen Peptide, Soy Protein Isolate and Fish Collagen Peptide into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Bonito Elastin Peptide is sold as a food ingredient in Japan and is the subject of several products notified under the Foods with Function Claims (FFC) system, primarily on skin elasticity endpoints.
In China the ingredient is treated as a fish protein hydrolysate under general food provisions, with several specific products carrying Blue Hat health-food registrations.
The United States accepts the ingredient as a food component with self-affirmed GRAS, subject to FDA seafood HACCP requirements. Fish allergen labelling is mandatory.
In the European Union, fish protein hydrolysates from established food species generally do not require novel food authorisation, but the elastin-enriched nature of the product means individual operators may choose to file for legal certainty depending on intended use.
Halal and Kosher certification is achievable because the raw material is fish, although the source plant must meet the relevant certification body's process requirements.
Manufacturing Process
Production starts with bonito processing offcuts. The bulbus arteriosus, a small thickened structure at the base of the heart, is the single most elastin-rich tissue available at industrial scale. The aorta and other large vessels contribute additional raw material.
The tissue is cleaned, ground, and defatted, then subjected to a controlled alkaline or enzymatic pretreatment that loosens the elastin from the surrounding collagen and cellular matrix. This step is critical because elastin and collagen are intertwined and the value of the product depends on enriching the former.
Hydrolysis is then performed with elastase-active proteases. Pancreatic elastase, thermolysin, and some bacterial alkaline proteases are used, often in combination, to cleave the elastin into water-soluble peptides without destroying the desmosine crosslinks that suppliers use as quality markers.
The hydrolysate is heat-inactivated, filtered, decolorised, concentrated, and spray-dried. Supply is concentrated in Japan, where bonito processing infrastructure and the historical know-how on elastin extraction are both centred.
