A spray-dried salmon extract standardised to not less than 30% anserine, the imidazole dipeptide that migratory fish concentrate in their swimming muscle. Purified by ion exchange, activated carbon and nanofiltration, dried on a maltodextrin carrier and shipped with the Certificate of Analysis of its own lot. Water-soluble, 36-month shelf life, made in Japan.

Fifteen documented operations take the material from salmon raw material to a packed powder. The purpose of the chain is to concentrate anserine while stripping out the rest of the extract: ion exchange, activated carbon and nanofiltration do the purification, sterile filtration and pasteurisation set the microbiology, and two magnetic separators guard against metal fragments before and after sieving.

If you are comparing ingredients for a new SKU, these questions separate one material from another quickly.
The powder is standardised at 30% anserine minimum, so the dose decides the fill weight: 100 mg of anserine is about 333 mg of powder, 300 mg is about 1 g. Capsule count, stick size and cost per serving all follow from this one number.
The active comes from salmon and the allergen is declared as salmon. Fish is a priority allergen in most markets and must appear on the label; a brand positioned as allergen-free or vegan cannot use this ingredient.
The maltodextrin is corn-derived and its GMO status is declared as unknown by the producer. If your market or retailer requires a non-GMO statement, say so before ordering so we can check what the producer can document.
The importer registers the finished product. Routes differ: a product licence in Canada can take six months or more, the EU novel-food status of this material has not been verified, and the UAE asks for a halal certificate on supplements. Plan the timeline before the first commercial order.
These are not measured at the source. The powder is sieved at 0.84 mm and dissolves in water; if your filling line needs density or particle-size figures, run them on the free sample rather than waiting for a document that does not exist.
The powder has a slight bitter note and no salmon flavour. Capsules and tablets hide it; stick packs and drinks usually need flavour masking. Test the sample in your actual base.

Anserine is one of the two imidazole dipeptides found in animal muscle, the other being carnosine. Mammals, including humans, carry mostly carnosine; birds and migratory fish carry mostly anserine, and salmon muscle is a rich natural source. This powder is that anserine, taken out of salmon extract, purified and standardised to not less than 30%, then spray-dried on maltodextrin so that it handles like any other dry active.
It is a food ingredient made from a food raw material. The anserine is separated and purified from the extract, not synthesised, and the finished powder carries an ordinary food specification: imidazole dipeptide content, moisture, plate count, coliforms, nutrition per 100 g. It is not a reagent-grade pure peptide, and it is not a whole fish protein hydrolysate: 43% of the powder is the purified extract and 57% is the carrier.
Two practical consequences follow. First, the carrier makes the powder free-flowing and water-soluble, so it goes into capsules, tablets, stick packs and beverages without a wetting step. Second, the standardisation is a minimum: your lot's Certificate of Analysis states the measured anserine value, and that value, not the 30% floor, is the number to use when you set a fill weight.
Imidazole dipeptides are part of the muscle's own buffering system. The powder goes into capsules, tablets and powdered drinks, and the fill weight follows directly from the anserine dose you choose.
Anserine sits comfortably in Japanese-heritage wellness positioning next to actives such as fish collagen tripeptide or nattokinase: a defined molecule from a named food source with a transparent process.
The powder dissolves in water and the producer also makes a liquid frozen grade with a lower anserine content for drinks and jellies, quoted on request. Because the powder has a slight bitter note, sweetened or citrus bases usually mask it; test the free sample in your own base.
The notes below describe what independent authors studied and in what setting. They are not claims about this product, and none of the studies used this grade.
The producer's specification covers appearance, imidazole dipeptide content, moisture, total plate count and coliforms, with nutrition per 100 g. Raw-material origin and allergen status are documented per component: salmon from Japan and other countries, maltodextrin from US corn with GMO status declared as unknown. The Safety Data Sheet classifies the powder as not hazardous under GHS and reports an acute oral LD50 in mice above 3,646 mg/kg as imidazole dipeptide. Iizuka Shoukai supplies the specification and SDS before you order and the lot Certificate of Analysis with the goods.

Salmon Anserine Extract Powder is salmon extract purified to not less than 30% anserine, an imidazole dipeptide, and spray-dried on maltodextrin (43% extract, 57% carrier). A fish protein hydrolysate is the whole protein cut into peptides with no single active standardised; this powder standardises one defined molecule. Chicken-breast extracts contain both carnosine and anserine, with carnosine usually dominant; this grade declares anserine only. Iizuka Shoukai supplies it export-ready from Japan with the specification, SDS and lot CoA.
The minimum order is 500 g at 1,200 USD/kg; larger orders are quoted by volume and freight is quoted on request. Standard packing is a 10 kg bag, a 500 g bag or 10 x 100 g. Goods ship from Japan 1-1.5 weeks after payment is received; payment is 100% prepayment by SWIFT or Stripe. A 10 g sample is free for registered companies developing a product. Iizuka Shoukai also offers OEM finished-product manufacturing in capsules, sticks and tablets at our Tomioka Plant in Gunma, Japan, with a minimum of 5,000 units per SKU.
Work from the anserine value on your lot's CoA. At the 30% minimum, 100 mg of anserine is about 333 mg of powder and 300 mg is about 1 g, so the anserine dose sets the capsule count or stick weight directly. The powder is spray-dried, sieved at 0.84 mm, water-soluble and stable, with a 36-month shelf life. It has a slight bitterness and no salmon flavour: capsules and tablets hide it, drinks and sticks usually need a flavour system. Bulk density and particle-size distribution are not measured at the source, so run them on the sample if your filling line needs them.
The allergen is salmon (fish) and must be labelled in every market; the formula has no mammalian, poultry or porcine components. The maltodextrin is corn-derived with GMO status declared as unknown. Registration of the finished product is the importer's task and the route depends on the market: a product licence in Canada can take six months or more, the EU novel-food status of this material has not been verified, and the UAE requires a halal certificate for supplements. We supply the specification, SDS and lot CoA that these dossiers need; tell us your market when you request them.
