Apple seed oil (Calocarpum mamossum), or sapuyul oil is a fixed oil found in apple seeds. It is used in the cosmetic and medical industries. It is described as having an "almond-like odor" and a "mild, pleasant taste", and is also used as a cooking oil in some tropical countries.[1]
The pectin in apples results in apple seed oil having the ability to ease stomach cramps and prevent diarrhea. This pectin may also reduce diabetics' blood sugar levels, help contain cholesterol in the stomach, reduce levels of lead and mercury in the body, and possibly hinder or stop the spreading of cancer throughout one's body.[2] Apple seed oil can also be used as a base for some aromatherapy compounds.[1] Apple seeds are slightly poisonous, however, due to their moderately high level of cyanide, so consuming large amounts of this oil is inadvisable.[2]
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). Analysis of amino acids in apple seeds concluded that they also contain a significant amount of sulfur. Other elements significantly found in apple seeds include phosphorus, potassium, magnesium, calcium and iron. This study also concluded that apple seed oil could be used as an edible oil, with the oil cake being used to supplement animal feed.[3]
In cosmetics, apple seed oil has long been used to produce items such as soap and shampoo. It has been said that it helps stop hair from falling out.[1]
The oil can be used for marmalade and jelly.[1]
