Hovenia Dulcis Extract Powder

Hovenia dulcis extract is made from the seed of the Japanese raisin tree, called zhi ju zi in Chinese trade, and not from the swollen fruit stalk or the leaves. Water extraction concentrates the soluble seed fraction, and the liquor is dried into a light brown powder that disperses in water.

The extract is supplied at a 10:1 ratio and milled to 80 mesh, with no marker percentage declared. It is a plain seed extract of a single named species, and no powder, marker grade or pure compound of Hovenia dulcis is listed beside it.

Hovenia dulcis Identity & Plant Part

The botanical entity is Hovenia dulcis Thunb., the Japanese raisin tree, a deciduous tree of the Rhamnaceae native to East Asia. The part used is the seed, the small, flat, dark brown seed of the fruit. The swollen, sweet fruit stalk that gives the tree its raisin name is a separate material and is not used here, nor are leaves or bark. Flavanonols and flavonoids, with saponins and alkaloids as lesser families, are the constituents reported for Hovenia dulcis seed, named here without figures. The flavanonol dihydromyricetin is the compound that dominates most searches for this tree.

What 10:1 Means for Hovenia Dulcis

The 10:1 ratio states concentration against the starting seed, and nothing more. It is not a dihydromyricetin figure, although that compound drives most of the searches. Many offers for hovenia extracts quote a single compound at a stated percentage, and they belong to a different, marker-based product. This Hovenia dulcis extract is the plain ratio form, and a buyer who needs a defined compound level will not find it here. Naming the species and the seed, rather than the fruit stalk, keeps the identity fixed.

Application Areas

Seed Extract Capsules

Hovenia dulcis extract fills two-piece capsules as a light brown powder with a faint sweet, grain-like note. Seed extracts can pack unevenly, so a flow aid in the premix and a fill-weight check at the start of the run keep the capsule weight steady.

Instant Drink Powders

In drink powders the extract gives a hazy, tan liquid with a mild sweet and slightly bitter taste. Fruit and tea flavors suit it, and a carrier such as maltodextrin keeps the small dose even from sachet to sachet.

Tablet Compressions

Tablets carry the extract at moderate inclusion with microcrystalline cellulose, and a film coat protects the powder from moisture. Granulate first, because the fine particles are hygroscopic and can stick to punches in humid rooms. Moisture protection in the pack keeps compressed tablets from softening during storage.

Fruit-Style Gummy Bases

In gummies the extract goes into the cooked base late, and the light brown tint is hidden under apple, pear or peach colors. Flavonoid-bearing extracts can darken as pH rises, so test the shade at the pH of the finished gummy.

Dry Stick Pack Blends

Single-serve sticks carry the extract with a soluble carrier and a flavor system, giving a repeatable dose. The seed fraction is mild enough that stick formulas need little masking, which keeps the ingredient list simple. Opaque stick film also keeps light away from the powder in bright retail displays.

Formulation Notes

Hovenia dulcis extract is a light brown powder with a faint sweet, nutty aroma and a mildly bitter taste. Dispersed in water, the extract forms a hazy, tan liquid, and a fine sediment settles on standing. The sweetness is faint and should not be counted on in place of a sweetener.

Seed water extracts take up moisture, so weigh the Hovenia dulcis extract in a dry room and reseal the pack after each draw. Clumping at the surface is the first sign of uptake. For capsule filling, premix with a free-flowing carrier, and for beverages, add the powder to the dry base before liquids.

Flavonoid-bearing powders can darken slowly on storage in light and heat. Keep Hovenia dulcis extract in opaque, sealed liners and away from warm spots, and rotate stock by date, since a darker powder at the surface is the first sign of age.
