at the end of the operations, the oil still containing hexane is sent to the final distillation in order to remove the hexane under vacuum (from 10 mm to 35 mm of mercury) between 70 stripping for 10 min. the composition of a crude oil extracted from seeds according to the above process is indicated below: organoleptic characters: oil with an orange-yellow color, having a characteristic odor. ______________________________________fatty acid composition:______________________________________myristic acid c14 ≦0.50%palmitic acid c16 4 to 10%palmitoleic acid c16' ≦2%stearic acid c18 ≦4%oleic acid c18' 45 to 65%linoleic acid c18" 9 to 17%linolenic acid c18''' 5 to 11%arachidic acid c20 ≦3%gadoleic acid c20' 2 to 8%behenic acid c22 ≦6%erucic acid c22' ≦5%lignoceric acid c24 ≦2%content of unsaponifiable matter ≧1.5 g/100 gcontent of carotenes (in mg/100 g) ≧25 mg/100content of tocopherols ≧0.1 g/100content of phenol derivatives (as ≧20 ppmgallic acid equivalent)content of triterpenic alcohol 0.1 to 1%(alpha-lupeol)content of total sterols: ≧0.8 g/100relative % of campesterol 18 to 24%relative % of stigmasterol 5 to 10%relative % of β-sitosterol 48 to 65%relative % of delta-5-avenasterol <5%______________________________________ example 2: preparation of a lupine oil concentrate by molecular distillation the molecular distillation is carried out by spreading the oil in a thin layer on the heated surface of a conical rotor rotating at high speed.
