Blueberry Seed Oil
Also: Bilberry seed oil, Vaccinium myrtillus seed oil, Vaccinium corymbosum seed oil, Highbush blueberry seed oil.
Calculate a 100 % Blueberry 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 35 Codex oils where both fields come from the same standard, the method's median error is 0.90 % and its 90th percentile 2.74 %, with no meaningful bias. 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 % Blueberry Seed Oil
Conventional qualities summed from the fatty-acid groups; a single-oil bar is a reference point, not a recipe.
Fatty-acid profile
| Fatty acid | Published range, % | Used | |
|---|---|---|---|
| Palmitic acid | C16:0 · saturated | 4.57–5.7 (typical 4.57) | 4.6 |
| Palmitoleic acid | C16:1 | 0.06 | 0.1 |
| Stearic acid | C18:0 · saturated | 1.45–2.8 (typical 1.45) | 1.5 |
| Oleic acid | C18:1 | 21.02–22.9 (typical 21.02) | 21.0 |
| Linoleic acid | C18:2 | 43.33–43.5 (typical 43.33) | 43.3 |
| α-Linolenic acid | C18:3 n-3 | 25.1–28.99 (typical 28.99) | 29.0 |
| γ-Linolenic acid | C18:3 n-6 | 0.08 | 0.1 |
| Arachidic acid | C20:0 · saturated | 0.14 | 0.1 |
| Gadoleic acid | C20:1 | 0.13 | 0.1 |
Where these numbers come from
Table 1 oil content, acid value and peroxide value; Table 2 fatty-acid composition, blueberry (Vaccinium myrtillus) column.
GLC area-%: 16:0 5.7, 18:0 2.8, 18:1 22.9, 18:2 43.5, 18:3 (9c,12c,15c) 25.1; refractive index 1.48. Used for min/max only.
Cited for the rejection only: Table 2 oleic 1.13-1.36 % in all five berry seed oils is not credible; no figure used.
Two measured seed oils, one per species, because 'blueberry seed oil' is sold from both. The 'typical' column is Table 2 of Bederska-Lojewska et al. 2021 (Molecules 26(24):7446, open access), seed separated from juice pomace (Hortex/Polfeed, Skrzynsko, Poland, 2020) that the paper identifies as blueberry, Vaccinium myrtillus L. (the European blueberry or bilberry), extracted with 70 % ethanol at low temperature under sonication, GC-FID: palmitic 4.57, palmitoleic 0.06, stearic 1.45, oleic 21.02, linoleic 43.33, arachidic 0.14, gamma-linolenic (C18:3 n-6) 0.08, eicosenoic (C20:1) 0.13, alpha-linolenic 28.99 %; myristic and C22:1 are printed as 0. The same column also gives 1.08 % C20:4 n-6 (arachidonic acid), which has no key in this schema and is left out; it is an unusual acid in a seed oil and the paper prints exactly the same 1.08 +/- 0.08 in its cranberry column, so it is not relied on. The stored acids sum to 99.77 % (100.85 % with the C20:4). Table 1 of the same paper: 18.06 % oil in dry seed, acid value 2.14 mg KOH/g, peroxide value 8.78 meq O2/kg. Min/max add the highbush blueberry (Vaccinium corymbosum) cold-pressed seed oil that PlantFAdb tabulates as dataset #17959 from 'Fatty acid composition and antioxidant properties of cold-pressed marionberry, boysenberry, red raspberry, and blueberry seed oils' (Parry et al., J. Agric. Food Chem. 2005; SOFA TAB_014458): palmitic 5.7, stearic 2.8, oleic 22.9, linoleic 43.5, alpha-linolenic 25.1 % (sum 100.0), refractive index 1.48. The two species agree closely: linoleic 43.3-43.5, alpha-linolenic 25.1-29.0, oleic 21.0-22.9 %. SAPONIFICATION AND IODINE VALUE are null: neither document prints one and no other allowed document opened here does; the recorded composition implies about 192 mg KOH/g by stoichiometry. READ AND NOT USED: Luo et al. 2021 (Foods 10(11):2530) analysed a commercial blueberry seed oil (Botanic Innovations, USA) at palmitic 7.47, stearic 2.38, oleic 1.15, linoleic 40.20, linolenic 48.80 %, but the same table gives 1.13-1.36 % oleic for all five berry oils, raspberry included, which every other analysis puts near 10-12 %, so the C18:1 peak was evidently lost and none of its figures are used. Osei et al. 2026 (Int. J. Food Sci., PMC13263769) profiled V. corymbosum cultivars on lipid extracted from whole dried berries, not seed oil. INCI: CosIng has both 'Vaccinium Myrtillus Seed Oil' (CAS 84082-34-8, EC 281-983-5) and 'Vaccinium Corymbosum Seed Oil' (no numbers); this record spans both species, so inci is left null for the maintainer to choose. FOR SOAP: about 72 % of the oil is linoleic plus alpha-linolenic acid, the same very unsaturated block as raspberry and cranberry seed oils; use it as a small superfat addition rather than a structural oil, and expect it to shorten the bar's shelf life.
