Lupin seed fats

Abstract

Lupin seed oil was investigated with a view to potential food use. Tabulated data from the literature show seed oil contents of 14-17% in Lupinus albus, 13-23% in L. mutabilis, with 56.6-60.6 and 56.2% oleic acid, and 16.5-23.4 and 27.7% linoleic acid resp. Analysis of the oil from L. albus var. Multolupa and 22 other species showed 50-60% oleic, 12-20% linoleic and <10% longer chain fatty acids (C20, C20:1, C22, C22:1) with <3% erucic (C22:1) acid. The unsaponifiable fraction resembled that of other edible oil, except for high phospholipid content.
