A plant-derived mineral powder made in Japan from sesame seed hulls. The hulls are roasted and ashed, the minerals are extracted with fermented lactic acid and spray-dried, so the calcium arrives in lactate form with no carrier or additive. Minimum 15% calcium, with magnesium and potassium from the same raw material. MOQ 10 kg.

Sesame stores minerals from soil and water at high concentration, but most of them are bound to oxalic and phytic acid as calcium oxalate and magnesium phytate. The process removes those binders by high-temperature roasting and ashing, then brings the minerals back into solution with fermented lactic acid. About 4,000 kg of sesame hulls give roughly 600 kg of finished mineral powder.
Step 1 · raw material
Sesame seed coat, the mineral-rich outer layer, sourced from several growing countries
Step 2 · high temperature
Oxalic and phytic acid are removed; 4,000 kg of hulls yield about 500 kg of ash
Step 3 · 8 hours
Ash is stirred in 50% fermented lactic acid; minerals pass into solution as lactates
Step 4 · diatomaceous earth
Clear mineral solution, filtration aid removed
Step 5 · drying
Solution to powder, about 600 kg per batch
Step 6 · release
Appearance, calcium content, loss on drying, microbiology; 5 kg bags in cartons

Sesame is a mandatory allergen in several markets, including the USA and the EU. Check your label rules before formulating.
The production line also handles wheat, milk, soy, pork and gelatin. Ask for the allergen statement if your product carries a free-from claim.
Neither certificate is currently held for this material. For markets such as the UAE this decides whether the ingredient can be used.
The powder dissolves in water and takes up moisture. Plan moisture-barrier packaging for sticks and sachets.

Most calcium on the ingredient market comes from rock (calcium carbonate), from shell (oyster, coral, eggshell) or from chemical synthesis (citrate, gluconate). Sesame mineral powder takes a different route: the calcium, magnesium and potassium are the minerals the sesame plant itself concentrated from soil and water and stored in its seed hull.
The hull is also where the problem sits. In the raw plant those minerals are largely locked up as calcium oxalate and magnesium phytate, forms the human gut absorbs poorly. The producer's method is to burn off the organic binders by roasting and ashing, then redissolve the mineral ash in fermented lactic acid. What comes out of the spray-dryer is a mineral lactate powder: white to pale yellow, water-soluble, with no carrier or excipient.
The powder has been used by the producer as the mineral base of pressed tablets, and the same properties apply to capsules, powder sachets and beverage premixes. Points to plan around:
The producer reports two animal studies on its website: a comparison of calcium uptake into blood in rats after intestinal administration of the powder against other calcium sources, and a bone-density measurement in ovariectomised rats fed a low-calcium diet with and without the material. The producer also ran an internal one-year observation in which volunteers took sesame-based tablets delivering about 157 mg of calcium per day, with bone density measured by quantitative ultrasound before and after. These are producer data, not peer-reviewed publications, and they are not claims about this ingredient; the study descriptions are available on request for your own evaluation.
The following summarises the calcium fact sheet of the US National Institutes of Health Office of Dietary Supplements. It describes the nutrient, not this product.
Calcium is the most abundant mineral in the human body. Almost all of it, about 98%, is stored in the bones, where it forms the calcium-phosphate matrix of bone and teeth. The small ionised fraction in blood and tissue takes part in blood vessel contraction and dilation, muscle function, blood clotting, nerve transmission and hormone secretion.
The US recommended dietary allowance is 1,000 mg per day for adults aged 19 to 50 and for men up to 70, and 1,200 mg per day for women over 50 and for everyone over 70. Reference values in other markets differ; the regulator of the target market sets the figure used on a label.
Absorption of calcium from dairy products and fortified foods is about 30%. Plant compounds such as oxalic acid and phytic acid bind calcium into salts the body cannot digest: absorption from spinach is about 5%, against 27% from milk. Absorption also falls as the single dose rises, from roughly 45% at 200 mg per day to 15% at intakes above 2,000 mg per day, which is why calcium is usually split across the day. Caffeine and phosphorus reduce absorption slightly; low vitamin D status reduces it more.
The two most common supplement forms are calcium carbonate (about 40% elemental calcium by weight) and calcium citrate (about 21%). Carbonate is absorbed better with a meal, because it needs stomach acid; citrate is less dependent on stomach acid. Calcium lactate, the main form in sesame mineral powder, is listed among the other forms used in supplements. For any form, the amount of elemental calcium per serving is the figure that matters on the label.

The specification guarantees not less than 15% calcium, so 1 g of powder delivers at least 150 mg of calcium. Recent lots measured 15.0% and 16.0%. The same gram also carries about 8.5 mg magnesium and 9 mg potassium (typical values). Formulate on the minimum and confirm with the lot CoA.
Yes. The minerals are the ones the sesame plant stored in its seed hull; the only other material is lactic acid fermented from corn. No animal-derived material is used and raw materials are non-GMO. The powder contains sesame, which is a declared allergen in many markets.
Iizuka Shoukai supplies sesame mineral powder at 145 USD/kg for the 10 kg minimum order, packed in 5 kg polyethylene bags in cartons. Larger orders are quoted by volume and freight is quoted on request. Ships from Japan 1-1.5 weeks after payment. Payment is 100% prepayment by SWIFT or Stripe. We also offer OEM finished-product manufacturing in capsules, sticks and tablets at our Tomioka Plant in Gunma.
Carbonate and shell calcium are mineral or animal sources in carbonate form, with about 40% elemental calcium, and they are poorly soluble in water. Sesame mineral powder is a plant source in lactate form with a minimum of 15% calcium, it is water-soluble, and it brings magnesium and potassium from the same raw material. The producer has compared calcium uptake in rats against other sources; we share that study description on request but do not make absorption claims for the ingredient.
