Apple seed oil oil, with the oil cake being used to supplement animal feed.

Apple seed oil Apple seed oil is a fixed oil found in apple seeds. It is used in the cosmetic and medical industries. A study on apple seed oil was conducted in 2007 which found that apple seeds contain a high amount of both oil and protein (27.5 to 28% and 33.8 to 34.5%, respectively).

Phlorizin is a flavonoid that is found in apple trees, particularly in the leaves, and in only small amounts if at all in other plants, even other species of the genus "Malus" or related plants such as pear trees. Apple seed oil and pectin can be produced. Preliminary research is investigating whether nutrients and/or phytochemicals in apples may be preventive against the risk of some types of
