Strawberry Seed Oil

INCI Fragaria Ananassa Seed Oil. Also: Fragaria ananassa seed oil.

Calculate a 100 % Strawberry Seed Oil bar

The saponification value here is derived, not published. No primary document we could use gives one for Strawberry Seed Oil, so it is calculated from this record's own fatty-acid composition: chain lengths fix the molar mass, which fixes how much hydroxide a gram of fat consumes. That gives 191.8 mg KOH/g, ±3 %.

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.

Sections 4.1 (seed origin) and 4.5 (FAME/GC-FID); Table 6 fatty-acid content of the seed oils, strawberry column.

Every field is Table 6 of Kieltyka-Dadasiewicz et al. 2025 (Int. J. Mol. Sci. 27(1):41, open access): strawberry (Fragaria x ananassa) seeds separated from juice pomace by a Polish processor (H.J.C. Polecki Trading, Srem; 2021), lipids Soxhlet-extracted with n-hexane, FAMEs by GC-FID: palmitic 2.16, palmitoleic 0.20, hexadecadienoic (C16:2, no key) 0.10, stearic 0.76, oleic 11.33 (10.81 n-9 plus 0.52 cis-vaccenic), linoleic 54.17, gamma-linolenic 0.10, alpha-linolenic 30.48, arachidic 0.40, eicosenoic 0.20, behenic 0.10 %; myristic and stearidonic 0.00. The paper's subtotals (SFA 3.42, MUFA 11.73, PUFA 84.85 %) reproduce exactly and the stored acids sum to 99.90 %. THIS IS ONE SAMPLE: its palmitic acid (2.16 %) is lower than most published strawberry seed oils, and the authors say fatty-acid composition was not the paper's main aim. No second strawberry seed-oil analysis could be opened - Pieszka et al. 2015 (J. Chem. 2015:659541) is open access but its host refused automated access, and PlantFAdb's only strawberry-seed row carries an unrelated publication title - so the record has no min/max. A Lithuanian study of cold-pressed berry seed oils (Ispiryan and Jariene, Foods 14(20):3494, 2025) describes strawberry oil in its text as about 42 % linoleic, 35 % alpha-linolenic and 15-16 % oleic, without an acid-by-acid table: the same very unsaturated block with the linoleic/linolenic split moved, which is usual for berry seed oils. SAPONIFICATION AND IODINE VALUE are null: not measured; the composition implies about 192 mg KOH/g. FOR SOAP: about 85 % polyunsaturated (linoleic plus alpha-linolenic), in the same class as raspberry seed oil - a small superfat addition, not a base oil. INCI 'Fragaria Ananassa Seed Oil' is an active CosIng entry without CAS or EC numbers.
