A Japanese trading company selling directly to brand owners and contract manufacturers. No distributor layer between you and the documents.
Every shipment travels with the Certificate of Analysis of its own lot, with the measured values and the full safety panel.
A small first order lets you run a pilot batch before committing to bulk. Larger volumes are quoted by volume and delivery terms.
For registered companies developing a product. Tell us the format you plan and we will say honestly what to expect.
After payment is received. Freight quoted on request. Specification and SDS before you order, CoA with the goods.
If you are comparing ingredients for a new SKU, these questions separate one material from another quickly.
Barley is listed as a gluten-containing cereal in EU and US labelling rules, and the specification has no gluten test. Settle the allergen statement for your market before launch.
Halal certification is not part of this product's documents. If you sell supplements in a market that requires it, such as the UAE, ask before ordering.
The powder is highly hygroscopic and is stored below 15 °C. Plan moisture-barrier stick film or sachets, and reseal opened bags.
Shelf life runs 1 year from the date of manufacture. Count shipping time, your production run and the shelf life of your own product when you plan the order size.
If you need finished aojiru stick packs rather than bulk powder, ask about OEM production in Japan.

Aojiru, the Japanese green drink, is by definition the juice of raw green leaves. This ingredient follows that definition: juice is pressed from fresh young barley leaves grown in Japan, heat-treated and spray-dried on a dextrin carrier, instead of drying and milling the whole leaf.
The grade on this page is a heat-treated, spray-dried powder. Its specification sets total plate count at max. 3,000 CFU/g and moulds and yeasts at max. 100 CFU/g, with coliforms negative.
Formats: aojiru stick packs, powdered drinks and blended green powders.
Blends: the producer's formulation examples combine the extract with collagen peptide, hyaluronic acid, acacia fibre, lactic acid bacteria, mulberry leaf, moringa leaf, fruit juice powders and matcha.
The powder is highly hygroscopic. Store it below 15 °C and plan moisture-barrier packaging for the finished product.
Related ingredients: organic ashitaba powder, another Japanese green leaf for aojiru-type drinks; matcha powder for flavour blends; and fish collagen tripeptide for collagen aojiru concepts.
Finished stick packs can be produced in Japan through our OEM service. Request the specification, a quote or a sample.
Barley grass is the young green leaf of the common barley plant, Hordeum vulgare L., family Poaceae (Am J Chin Med, 2015). In Japan young barley leaves are widely sold as the base of aojiru, the green drink. The notes below describe the raw material class, not measured properties of this product, and they are not claims.
Reviews of barley grass list a broad set of constituents: chlorophyll; flavonoids, notably saponarin and lutonarin; gamma-aminobutyric acid (GABA); the enzyme superoxide dismutase (SOD); vitamins A, B1, C and E; minerals such as potassium and calcium; essential amino acids; and dietary fibre (Am J Chin Med, 2015; Oxid Med Cell Longev, 2018).
The amounts depend on the plant and how it grows. In a study on barley leaves, phenolic compounds and chlorophyll changed with leaf age, light exposure and barley variety (Plant Physiol Biochem, 2018). The specification of this product does not state nutrient contents, so we do not quote figures for it.
Saponarin is a flavonoid found in young green barley leaves and is usually reported together with lutonarin. In laboratory tests, saponarin and a saponarin and lutonarin mixture reduced the oxidation of fats and oils exposed to UV light or Fenton's reagent, measured as malonaldehyde formation (J Agric Food Chem, 2012). These were test-tube experiments on isolated compounds, not studies in people.
Barley grass reaches the market in two main forms. Milled powder is the whole dried leaf, so it keeps the cellulose cell walls and insoluble fibre. Juice powder is made from the liquid pressed out of the fresh leaf cells, so it carries mainly the water-soluble part of the leaf. The choice changes texture, how the powder behaves in water and the nutrition label, so it is worth specifying which form a formula uses.
The reviews cited here summarise laboratory, animal and a smaller number of human studies on barley grass and its extracts, mostly on antioxidant and metabolic endpoints. The studies used different preparations and doses, and none was carried out on this product. They show what has been studied in the raw material class; they are not claims about this ingredient.
