mustard oil[′məs·tərd ‚ȯil]
a fatty vegetable oil produced from the seeds of the mustard plant. It contains the following fatty acids (in percent): stearic, to 0.5; palmitic, to 0.2; lignoceric, 1–2; behenic, 2–3; oleic, 22–30; linoleic, 8–12; linolic, 14–19; erucic, 11–53; and arachidic, 7–14. Mustard oil hardens at a temperature of -8° to -16° C; its iodine number is 92–107 (sometimes 122). It is highly nutritious, does not oxidize readily, and does not become rancid during prolonged storage. It is used in food, in baking bread, and in confectionery and canning, as well as for industrial purposes.
