What are the advantages of cold pressing?
The oil produced with cold pressing technologies is of very high quality. In our experience, cold pressed rapeseed oil is suitable for biodiesel production (estherification) without any further processing. This means that the critical quality measure for estherification, the phosphorus content, remains desirably low below 35 ppm. As opposed to this, vegetable oil produced with hot pressing technology typically has a phosphorus content of 200-500 ppm; therefore, if the desired use of the oil is biodiesel production additional investment in degumming technology (to reduce the phosphorus content) is inevitable.
