Expeller Pressed vs. Cold Pressed

What is Expeller Pressing?
Expeller pressing is a chemical-free mechanical process that extracts oil from seeds and nuts. This method of oil extraction is an alternative to the hexane-extraction method used for many conventional oils. The temperature reached during pressing depends on the hardness of the nut or seed. The harder the nut or seed, the more pressure required to extract the oil, which in turn creates more friction and higher heat. There is no external heat applied during the expeller pressing

Why Cold Press?
Delicate oils, or those in which flavor nuances are a key component, need to be treated with greater care in controlling processing factors. Oils that are cold pressed are expeller pressed in a heat-controlled environment to keep temperatures below 120 degrees F.

It's important to note that, while Europe has rigorous standards in place for the terminology of cold pressing (fully unrefined oil extracted at temperatures below 122 degrees F), the phrase 'cold pressed' has been used erroneously in the U.S. for a number of years, often employed as a marketing technique for oils which have been expeller pressed or even refined (which exposes the oil to temperatures of up to 470 degrees F).

How Does Spectrum Decide?
We choose an appropriate extraction process based on the characteristics of the particular seed or nut and the desired oil.

All of Spectrum's oils are naturally expeller pressed*. Spectrum's EFA oils and Extra Virgin Olive Oils are cold pressed, to let their delicate, unique flavors shine through.
