Saraca Asoca Extract Powder

Saraca asoca extract starts from the bark of the ashoka tree, an evergreen of the legume family native to India and Sri Lanka. Water extraction concentrates the soluble bark fraction, and the liquor is dried to a light brown powder that disperses in water.

The extract is supplied at a 10:1 ratio with no marker percentage and is milled to 80 mesh. A tannin-graded ashoka extract is a separate product, so this ratio extract is the entry for buyers who need a whole-bark water concentrate rather than a numeric tannin target.

Saraca asoca Identity & Plant Part

The botanical entity is Saraca asoca (Roxb.) W.J.de Wilde, the ashoka tree, an evergreen legume native to India and Sri Lanka. The part used is the bark. Flowers, leaves and pods are not part of this ingredient, even though the flowers are prominent in traditional descriptions of the tree.

The older name Saraca indica still appears on commercial lists, and trade material sometimes substitutes the unrelated false ashoka, Polyalthia longifolia, which has a very different bark. Saraca asoca bark carries tannins, catechin-type flavonoids, sterols and sugars, named as constituent families only.

Saraca asoca Extract vs Tannin-Graded Extract

Form	What It Is	Choose It When
10:1 Bark Extract	Water-extracted and concentrated ashoka bark	A whole-bark concentrate without a marker target is specified
Ashoka Bark Extract 5% Tannins	Separate extract graded by tannin content	A defined tannin grade is the specification

The 10:1 ratio is a concentration step from bark to dry extract. It is not a tannin figure, and the tannin grade in the sibling is measured differently from anything on this entry. A buyer who needs a numeric tannin value should specify the graded extract.

The ratio extract suits formulas that want the full water-soluble profile of Saraca asoca bark. Tannin-rich bark extracts are astringent and darken in alkaline or iron-containing mixes, which is why the ratio extract is often the starting point for small trials before a graded product is considered. Saraca asoca extract keeps the soluble tannin share of the bark.

Application Areas

Capsule Fills for Ashoka Bark

Two-piece capsules take Saraca asoca extract as a free-flowing brown powder after a flow aid is added, and the astringent bark taste stays inside the shell. Weight uniformity and disintegration are the two checks that matter most for the finished capsule lot.

Dry Tablet Granulations

Tablets compress with microcrystalline cellulose and a disintegrant. Tannins can bind to protein and some excipients, so compatibility trials on the granulate are sensible. A film coat covers the dark color and the dry, astringent taste of the compressed core.

Tea-Style Instant Powders

Instant sachets blend the extract with spice flavors such as cardamom, clove and cinnamon. The cup is a deep amber and stays clear to hazy, and sweeteners reduce the dry mouthfeel that tannins leave behind, so a small sugar or polyol share is usually included.

Mineral-Free Stick Blends

Stick packs combine the extract with other botanical extracts in dry blends. Tannins react with iron salts to darken the powder, so mineral premixes containing iron are kept out. A mixing study confirms even color across the stick and across the filling run.

Fortified Bar Binders

Bars take the extract in the dry fraction with dates, oats and seeds, where the bark’s astringency is covered by date paste and cocoa. Adding the powder before the syrup avoids lumps and uneven color in the finished bar.

Formulation Notes

Saraca asoca extract is a light brown powder with a woody, faintly smoky aroma and a dry, astringent taste. In water it disperses to a hazy amber-brown liquid. Tannin-containing powders of this kind darken with heat, light and alkaline conditions, so the color of the finished format is checked during stability trials and not only at release.

Weigh the powder in a dry room and premix it with a flow agent for capsules and sticks. Keep it away from iron and other reactive metal salts in premixes. After opening, reseal the pack and store it in a closed container out of direct light, which protects both flavor and shade.
