Aronia Seed Oil (Black Chokeberry)
Also: Black chokeberry seed oil, Chokeberry seed oil, Aronia melanocarpa seed oil.
Calculate a 100 % Aronia Seed Oil bar
That is stoichiometry on a measured composition rather than a guess, and it is about as well determined as a published figure: checked against the 36 Codex oils where both fields come from the same standard, the method's median error is 0.84 % and its 90th percentile 2.44 %, and it runs slightly high, by 0.55 % on average. The formula page shows the working. If you have a certificate of analysis for your lot, enter its measured value in the calculator and this estimate is set aside.

A bar made of 100 % Aronia Seed Oil
Conventional qualities summed from the fatty-acid groups; a single-oil bar is a reference point, not a recipe.
How much lye
| Oil | NaOH | KOH |
|---|---|---|
| 500 g | 64.8 g | 90.9 g |
| 1 kg | 129.7 g | 181.9 g |
| 1 lb (454 g) | 58.8 g | 82.5 g |
| 2 lb (907 g) | 117.6 g | 165.0 g |
For this oil alone at 5 % superfat, with pure sodium hydroxide (NaOH) or pure potassium hydroxide (KOH); in brackets, across the published range of its saponification value. KOH is usually sold at 90 %: divide by 0.9. For a whole recipe, open the calculator.

GLC area-% fatty acids (23 data points, total 97.8). Used for the min/max; its provenance is weaker than a published paper.
A linoleic-acid oil (about 67-71 % linoleic, 21 % oleic) from the seeds of black chokeberry (Aronia melanocarpa). No recent open-access analysis of the oil could be found, so the record rests on the two Aronia datasets in PlantFAdb. Typicals: dataset #11362, 'Lipid composition of Bulgarian chokeberry, black currant and rose hip seed oils' (1999; SOFA TAB_013869; oil content 19.3 %), GLC area %: 14:0 0.0, 16:1 0.0, 16:0 5.1, 18:3 0.5, 18:2 71.1, 18:1 21.4, 18:0 1.1, 22:0 0.8 (sum 100.0). Min/max add dataset #10704 (SOFA TAB_002335, recorded in SOFA as 'Unpublished (1998)'), GLC area %: 10:0, 12:0, 14:0, 15:0 each 0.0; 16:1 0.2; 16:0 4.8; 17:1 0.1; 17:0 0.1; 18:3 0.5; 18:2 66.9; 18:1 delta-11 0.6; 18:1 delta-9 21.0; 18:0 1.2; 19:0 0.1; 20:2 0.1; 20:1 0.3; 20:0 0.7; 21:0 0.1; 22:2 0.2; 22:1 0.3; 22:0 0.3; 24:0 0.1; 26:0 0.2 (total 97.8). Acids reported only in #10704 are stored as max; those without a field or under 0.3 % (C17, C19, C21, C26, cis-vaccenic 0.6, 20:2, 22:2, 24:0 0.1) are left out. NO SAPONIFICATION OR IODINE VALUE appears in either dataset or in any open document found, so both are null; the build derives the saponification value from the profile (all C16-C18). About 72 % of the fatty acids are polyunsaturated. CosIng has no INCI name for Aronia seed oil (only fruit, juice and callus extracts), so inci is blank.
