About Oilseed Extraction


The primary goal of oilseed processing is to extract as much oil as possible from the seed while consuming as little energy as possible. The result: two end products, oil and the leftover solids traditionally called meal.

The two most common methods for separating the oil from the oilseed are chemical extraction and mechanical extraction. With chemical extraction, there is less oil loss, but plants incur higher investment costs while yielding a lower value product.

While oil losses in the meal are slightly higher, around 5-8%, mechanical extraction does not expose the products to any harmful chemicals, yielding a much higher value product.
