Wheat germ is usually removed from the grain during milling because its
fat content can turn the flour rancid. Wheat germ oil has a nutty scent
and is thought to contain a wide variety of vitamins and minerals. Wheat
germ oil contains iron, phosphorus, fatty acids: linolenic and
alpha-linoleic acids.
Germ oil constitutes 3% of wheat grain weight and contains about 25% of
minerals, protein and vitamins and also has important antioxidant
properties.
Octacosanol is the main active component of policosanol and wheat germ
oil.
Octacosanol is a long carbon chain: CH
3(CH
2)
26CH
2O
14.
It has a natural mixture of high molecular weight alcohols and is
primarily isolated from sugar cane (Saccharum officinarum L) wax.
Small quantities of octacosanol are available in the human diet through
plants (mainly as a wax in the superficial layers of fruits), leaves,
skins of common plants, and whole seeds.
Wheat germ oil is best used without direct heat in finished dishes,
including soups, grains, salads, or blended into dressings and
smoothies. They can also be taken directly without food, as a dietary
supplement.
