19
Q

how is the palm kernel oil extracted

Palm kernel oil (PKO) is extracted from the seed or nut of the palm fruit by prepress-solvent extraction

20
Q

what is the fatty acid profile of the palm kernel oil simular to

A

The fatty acid profile of PKO is similar to that of coconut oil and, for most purposes, the oils are interchangeable

21
Q

what is the lauric acid ratio and what is coconut oils used for

A

Lauric acid (C12:0) from PKO and coconut oil is used in shortenings, confectionary fats, detergents and shampoos.
