Anotations

Scope note:

Plant oil extracted from the mesocarp of the fruit of some palms, particularly the West African oil palm (Elaeis guineensis). The outer fleshy portion of the fruit is steamed to destroy the lipolytic enzymes and then pressed to recover the palm oil, which is highly coloured from the presence of carotenes. Palm oil is used in making soaps, candles, and lubricating greases and in processing tinplate and coating iron plates.
