Bitter Orange Flower Extract Powder

Bitter orange flower, the white, strongly scented blossom of the sour orange tree Citrus aurantium that is also the source of neroli, is the only plant material behind this extract. The flowers are extracted in water, concentrated and dried to a yellow-orange powder. Fruit, peel and leaves are not part of the material.

This bitter orange flower extract is a 10:1 ratio extract with no marker assay and no flavonoid figure. The powder is milled to 80 mesh and disperses in water. Because the solvent is water, the volatile oil of the blossom is not concentrated in the powder.

Citrus aurantium Flower Source & Identity

The botanical entity is Citrus × aurantium L., the sour or Seville orange, a thorny evergreen tree of the rue family, Rutaceae, grown around the Mediterranean and in Asia for its blossom, fruit and leaves. The part used here is the flower. The fruit, the peel and the leaves, which give petitgrain, are separate raw materials and are not included in this bitter orange flower extract.

Orange blossom from sweet orange, Citrus sinensis, is a different taxon, and so are lemon and mandarin blossom. Neroli oil and orange flower water are distillates of the same blossom, not water extracts dried to a powder, so they are different ingredients.

Flavonoid glycosides, phenolic compounds and a small amount of residual volatile oil are the constituent families expected in a blossom extract.

What 10:1 Means for Bitter Orange Flower

It is not a flavonoid or essential oil assay. The 10:1 ratio measures blossom going into the extract, and the aroma compounds of orange flower are volatile, so water extraction and drying keep the soluble matrix of the flower and lose most of the fragrance.

Bitter orange flower is a different material from the bitter orange fruit extract listed as Bitter Orange Extract Powder. The species is the same, but the part differs, and the specification name should state the flower. The peel of the same species is listed separately as the Bitter Orange Peel Extract Powder, and the STX grade Citrus aurantium Extract 6–30% Synephrine is built on a synephrine figure instead of a plant part.

Application Areas

Capsules for a Floral Extract

Bitter orange flower extract fills hard capsules after a flow check at 80 mesh. Flower extracts can pick up moisture from the air, so fill in a controlled-humidity room and keep the hopper covered. Check the fill weight of early capsules, and use a glidant only if the powder arches in the hopper.

Tablets with Film Coating

Tablets use a dry binder, with the lubricant mixed in at the end of the run. A film coat covers the yellow-orange core and slows moisture uptake. Check hardness when pressed and again after a week in the finished pack.

Floral Tea and Drink Sticks

Orange blossom is a familiar note in teas and in Mediterranean and Middle Eastern drinks. Bitter orange flower extract disperses in water to a golden, lightly hazy liquid, and a floral or citrus flavour supplies the aroma that water extraction leaves out. Test taste at the planned dose before fixing the stick fill weight.

Single-Serve Sachets

Sachets carry bitter orange flower extract in a sugar or fibre carrier. Sieve the powder into the carrier before filling so that the yellow-orange tone is even, and run a dose-uniformity check at the start, middle and end of the filling run.

Bar and Gummy Premixes

The soft floral character fits honey, almond and citrus bases. In a bar, the extract goes into the dry ingredients before the syrup, and in gummies it joins the dry sugar portion before cooking. A taste trial after a week shows how the note holds in storage.

Formulation Notes

Bitter orange flower extract is a yellow-orange powder with a faint, sweet floral smell and a mild, slightly bitter taste. In water it forms a golden dispersion with a light haze. Most of the volatile oil is lost with the water extraction, so the fragrance of a finished drink depends mainly on the flavour system.

Judge colour and taste in the real base at the finished dose, because flavonoid-type colour can shift with pH and fade in strong light. Opaque or amber packaging protects finished beverages.

Sprinkle the powder into stirred water, or wet it with a little liquid first, so that no dry lumps form. For dry mixes, sieve it with part of the carrier before blending. Reseal opened drums with the air pressed out and keep them in a cool, dry place.
