SFAD (SODD) is a by-product of the soybean oil refining produced in the deodorization step. SODD is a complex mixture composed of fatty acids, sterols, tocopherols, sterol esters, hydrocarbons, breakdown products of fatty acids, aldehydes, ketones and acylglycerol species. It is an important source of natural tocopherols and phytosterols corresponding approximately 8% and 20%, respectively.

Tocopherols prevent diseases like cancer, cardiovascular and cataracts . They are used in food, cosmetics and pharmaceutical industries . Tocopherols are sensible to light, heat, alkali and contaminant metals.

Phytosterols are valuable precursors in the production of hormones. They have hypocholesterolemic, anticarcinogen properties. They are used in manufacturing progesterone, corticoids, estrogens, contraceptives, diuretics, male hormones and vitamin D. They are, also, used in cosmetics, food like margarine, salad oils and dressings.
