Olive Leaf Extract Powder

Silvery-backed evergreen leaves of Olea europaea, the Mediterranean olive tree, supply this olive leaf extract, with the fruit, pits and pomace left out. Water extraction concentrates the soluble leaf fraction, and the liquor is dried into a green powder that wets and disperses in water.

This is a 10:1 ratio extract milled to 80 mesh, and it carries no marker percentage. Oleuropein-defined olive leaf extract is a separate standardized product, and the plain dried leaf is offered as a milled powder. A separate olive fruit extract covers the fruit-based material.

Olea europaea Identity & Plant Part

The botanical entity is Olea europaea L., an evergreen tree of the Oleaceae family cultivated across the Mediterranean basin. The part used is the leaf, the narrow leathery blade with a pale silvery underside. Fruit, stone, bark and pomace are not part of this ingredient, even though all of them are sold under olive names.

Olive leaf is rich in secoiridoids, with oleuropein the best known, and in phenolic compounds such as hydroxytyrosol precursors. Olive fruit extracts and olive pomace extracts draw on a different matrix, so a hydroxytyrosol description on a fruit page does not describe this leaf extract.

Olive leaf is also sold as a cut dried leaf for infusions. That cut is a tea material, not an olive leaf extract, and the 10:1 powder here is the concentrated, dispersible form of the leaf.

Olive Extract vs Powder & Standardized Grades

Form	What It Is	Choose It When
10:1 Leaf Extract	Water-extracted, concentrated and dried olive leaf	A dispersible leaf extract is wanted without a marker
Olive Leaf Extract 10–40% Oleuropein	Standardized extract with a defined oleuropein range	The specification names an oleuropein figure
Olive Fruit Extract Powder	Ratio extract of the olive fruit instead of the leaf	The fruit matrix, not the leaf, is the target
Olive Leaf Powder	Dried, milled olive leaf with no extraction	Whole leaf with fiber is needed at higher inclusion

The 10:1 ratio records how much olive leaf went into the extract. It states no oleuropein figure, which is why a labelled oleuropein content belongs to the standardized grade. Oleuropein is a glycoside that breaks down under heat, acid and enzyme action, so two extracts of equal ratio can end up with different secoiridoid profiles depending on how the leaf was handled.

The three siblings change the basis of the specification. The standardized extract adds an oleuropein range, the fruit extract moves to a different part of the tree, and the milled leaf adds back the insoluble fiber. A formula that must declare oleuropein starts at the standardized extract, and one that wants a plain dispersible olive leaf ingredient starts here.

The part decides the profile: an olive fruit extract and an olive leaf extract with the same ratio differ in color, taste and constituent family, so the ratio alone never identifies the material.

Application Areas

Olive Leaf Capsule Fills

The extract is filled into two-piece capsules after premixing with a flow aid. Its green color shows through clear shells, so opaque capsules are common, and disintegration is worth checking on the finished fill because the powder disperses rather than dissolves.

Herbal Tea-Style Instant Mixes

Olive leaf has a long tradition as a herbal infusion, which makes tea-style instant mixes a natural fit. The extract disperses into a hazy green-brown cup with a bitter edge, so lemon or mint notes are the usual flavor match. Instant olive leaf mixes work best with a dispersible carrier that keeps the extract suspended.

Sachet Powder Blends

Single-dose sachets combine the extract with fruit powders or a dispersible carrier. Matching particle size across components keeps the dense green extract from settling out of a lighter base during filling and transport. Light-colored fruit powders show the green tint plainly, so a darker base hides color differences between lots.

Formulation Notes

The powder is green to green-brown with a grassy aroma and a bitter, slightly astringent taste that comes from the leaf’s secoiridoids and phenolics. In water it disperses to a hazy olive-green liquid and does not form a clear solution.

Oleuropein-type glycosides are sensitive to heat and acid, so add the extract late in warm or acidic processing. Premix with microcrystalline cellulose before capsule filling, since a fine leaf extract packs densely and can bridge in a hopper. After opening, reseal the liner at every draw, because a moisture-affected leaf extract darkens and cakes. Weigh olive leaf extract in a dry room, since the powder takes up humidity at the surface.
