Coix Seed Extract Powder

Hulled kernels of Coix lacryma-jobi, the grass grown for its pearly Job’s tears seeds, supply this coix seed extract. Water extraction concentrates the soluble kernel fraction, and the liquor is dried to a light yellow powder at a 10:1 ratio. Husk, leaves and roots are left out of this extract.

The 10:1 ratio carries no marker percentage. The powder is light yellow, ground to 80 mesh and water dispersible. The milled coix seed powder and the coix peptide are separate products, and pearl barley is a different cereal.

Coix lacryma-jobi Seed Identity & Plant Part

The botanical entity is Coix lacryma-jobi L., a tall tropical grass of the family Poaceae. The part used is the seed, sold as the hulled kernel after the hard, glossy bead-like husk is removed. Leaves, stems, roots and husks are not added to this coix seed extract.

Job’s tears is often mistaken for pearl barley, Hordeum vulgare, because both are white, rounded kernels sold as grains, but the plants and the compositions differ. The coix kernel is rich in starch and protein and contains a lipid fraction with the glyceride mixture known as coixenolide, along with the benzoxazinoid coixol and polysaccharides. Water extraction leaves most of the lipid behind and brings the soluble sugars and polysaccharides into the powder.

Coix Seed Extract vs Powder & Peptide

Form	What It Is	Choose It When
10:1 Coix Seed Extract	Water-extracted, concentrated and dried C. lacryma-jobi kernel	A dispersible seed extract without a marker is wanted
Coix Seed (Job’s Tears) Powder	Milled whole kernel	Starch, protein and a grain profile are wanted
Coix Seed Peptide Powder	Coix-derived peptide ingredient	A peptide ingredient is required, not a ratio extract

The 10:1 on this coix seed extract counts ten parts of kernel against one part of powder. It gives no marker figure, and the milled kernel powder is a starchy flour that behaves very differently in water.

The ratio extract suits drink powders and capsule blends that want coix identity in a smooth, dispersible form, without the starch that makes milled coix cloudy and heavy. The milled kernel keeps its starch, protein and lipid, and the peptide is a distinct protein-derived ingredient.

Application Areas

Grain-Style Drink Powders

Drink powders use coix extract to build a mild, cereal-like flavor with a light yellow tone. The cup tastes faintly sweet and nutty, and it pairs with barley tea, soy or oat-style flavors. Warm water gives a smoother body than cold.

Mixed-Grain Capsule Blends

Capsule blends combine coix extract with other seed and grain extracts. The pale powder is fine and slightly sticky, so humidity is held low and a flow aid is considered. A trial run confirms fill weight before the capsule size is chosen.

White Tablet Cores

Tablet cores take the extract with a dry binder. The pale yellow color blends into a white tablet without mottling, and the soluble sugars bind well. Hardness is checked after storage, since the cores soften in humid air.

Soft Chew Premixes

Chew premixes accept the extract once the cooked base has cooled. A pale tint hides easily in vanilla, milk or honey flavors, and the extract adds a mild cereal sweetness that reduces the need for extra flavor.

Formulation Notes

The powder is light yellow with a faint, cooked-grain aroma and a mild, slightly sweet taste. In water it disperses to a pale, lightly opaque liquid. Because the starch has been separated from the extract, the cup does not thicken or set on cooling as a milled coix drink does.

Premix the powder into part of the dry base before the final blend to avoid sticky lumps. The soluble sugars absorb water readily, and a cake forms in an open pack within a day or two of humid weather. A moisture check on the blend is simple and avoids the problem.

Keep a used drum shut with the liner held against the powder, and away from grain stores. Cereal extracts attract pantry insects in warm stores, so drums are kept sealed and in a cool, clean area. Sensory trials should compare coix seed extract with a roasted-grain flavor and without it, because the unroasted extract tastes mild and a small flavor addition makes the cereal profile recognizable to consumers.
