Extracted from the seeds of the soya bean, soya bean oil accounts for around 80% of all commercial oil used in the US and around a third of all edible oil worldwide. Soya bean oil is commonly hydrogenated and used in a variety of processed foods; the hydrogenated oil has much more saturated fat than the un-hydrogenated version. Soya bean oil is usually used in baking and in the production of commercial, processed foods.
