Question

How do you make oil out of some fruits [like coconuts]?

Answer 1

Most commercial grade coconut oils are made from copra. Copra is basically the dried kernel (meat) of the coconut. It can be made by: smoke drying, sun drying, or kiln drying , or derivatives or a combination of these three. If standard copra is used as a starting material, the unrefined coconut oil extracted from copra is not suitable for consumption and must be purified, that is refined. This is because the way most copra is dried is not sanitary. The standard end product made from copra is RBD coconut oil. RBD stands for refined, bleached, and deodorized. High heat is used to deodorize the oil, and the oil is typically filtered through (bleaching) clays to remove impurities. Sodium hydroxide is generally used to remove free fatty acids and prolong shelf life. This is the most common way to mass-produce coconut oil. The older way of producing refined coconut oil was through physical/mechanical refining (see Tropical Traditions Expeller Pressed Coconut Oil.). More modern methods also use chemical solvents to extract all the oil from the copra for higher yields.

RBD oil is also sometimes hydrogenated or partially hydrogenated. This happens mostly in tropical climates, since the natural melting point of coconut oil is about 76 degrees F, and already naturally a solid in most colder climates. Since coconut oil is mostly saturated, there is little unsaturated oil left to hydrogenate. Hydrogenated oils contain trans fatty acids.

EDIT - Wet-milling. With this method the oil is extracted from fresh coconut meat without drying first. "Coconut milk" is expressed first by pressing.

Answer 2

She forgot to say that the plant material is usually pressed to release the oil. Olives are pressed to make olive oil.
