Rapeseed Oil - Low Erucic, High Oleic (High-Oleic Canola Oil)

INCI Canola Oil. Also: High oleic canola oil, High oleic low linolenic canola oil, High oleic rapeseed oil.

Calculate a 100 % Rapeseed Oil - Low Erucic, High Oleic (High-Oleic Canola Oil) bar

The saponification value here is derived, not published. No primary document we could use gives one for Rapeseed Oil - Low Erucic, High Oleic (High-Oleic Canola 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 190.4 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.

Tables 1-2 read and not used (see notes).

UNITS: grams of fatty acid per 100 g of oil, as USDA publishes them, NOT renormalised to percent of total fatty acids (the acids sum to about 95 g because the glycerol backbone is excluded; normalised figures would be about 5 % higher). Codex CXS 210 has no high-oleic canola column, so the source is USDA FoodData Central (SR Legacy), two commercial high-oleic canola oils; min/max span the two. 'Oil, industrial, canola, high oleic' (fdcId 171042, NDB 04698), per 100 g: total lipid 100.0; 14:0 0.0; 16:0 3.621; 18:0 2.01; 20:0 0.673; 22:0 0.289; 24:0 0.193; 16:1 0.191; 18:1 71.775 (18:1 c 71.488, 18:1 t 0.287); 20:1 0.673; 22:1 0.096; 18:2 13.394 (18:2 n-6 c,c 12.915; 18:2 t 0.478); 18:3 2.391 (18:3 n-3 c,c,c 2.2; 18:3 i 0.191); total trans 0.957; SFA 6.787, MUFA 72.734, PUFA 15.785. 'Oil, vegetable, Natreon canola, high stability, non trans, high oleic (70%)' (fdcId 171033, NDB 04678): 14:0 0.047; 16:0 3.437; 18:0 1.918; 20:0 0.674; 22:0 0.29; 24:0 0.145; 16:1 0.286; 18:1 69.97 (c 69.893, t 0.077); 20:1 1.348; 22:1 0.241; 24:1 c 0.145 (no schema key); 18:2 14.501 (n-6 c,c 14.339; t 0.163); 18:3 2.597 (n-3 c,c,c 2.07; 18:3 i 0.527); total trans 0.767; SFA 6.511, MUFA 71.991, PUFA 17.098. The oleic, linoleic and linolenic keys hold the USDA totals for 18:1, 18:2 and 18:3, including the small trans and isomer amounts listed, which is how Codex's C18:x columns are defined too. Erucic acid 0.10-0.24 g/100 g keeps this inside the low-erucic (canola) definition. NO SAPONIFICATION OR IODINE VALUE is published by USDA or in any open document found for high-oleic canola, so both are null; the build derives the saponification value from this profile (it renormalises, so the per-100-g units do not bias it). Read and not used: Zhang et al. 2023 (Food Chem. X 19:100804) report high-oleic rapeseed oils from China at 74-79 % oleic but with erucic acid 1.83-2.51 % (at or above the canola limit) and iodine values of 117-129 that their own profiles (about 11 % linoleic, 2 % linolenic) cannot produce (they imply about 93); Wroniak et al. 2021 (Antioxidants 10:1637) give a Polish cold-pressed high-oleic rapeseed oil at 16:0 3.01, 16:1 0.20, 18:0 1.99, 18:1 76.96, 18:2 8.71, 18:3 2.92, 20:0 0.66, 20:1 1.28, 22:0 0.58 g/100 g - consistent with this record in kind, but a different, more oleic cultivar, so not merged. The INCI name, CAS and (absent) EC number are those CosIng gives for Canola Oil ('an oil derived from Brassica napus L. ... low in erucic acid'), which does not distinguish the high-oleic type; CosIng lists no 'Sodium Canolate' or 'Potassium Canolate', so no saponified names are given.
