Expeller-pressed and cold-pressed oils are both methods of extracting oil from nuts or seeds, but there are some differences between the two processes. Here are some details, positives, negatives, and ingredients or materials of each method:

Expeller-Pressed Oils

• Details: Expeller pressing uses a press to squeeze the oil out of the seed rather than using chemicals. The screw drives forward to literally squeeze the oil from the compressed seeds. There isnt any added heat in this process, but the pressure and friction involved in the pressing process can create heat from the unit in the range of 140-210 F. So technically this process is not cold-pressed because the oil may not stay cool, even if no heat is added.
• Positives: Expeller pressed oil is more clean and pure as it does not contain any chemicals and has natural flavors and colors.
• Negatives: When expeller pressing, it takes a large number of nuts or seeds to create a high yield – which means more money. This is one of the biggest reasons why oil manufacturers aren’t keen on using this method of extraction and instead use methods that include chemicals and high heat.
• Ingredients or materials: Expeller pressed oils can be obtained from a considerable amount of distinct seeds, but only the ones that have been approved for consumption are sold to the public. Expeller pressed oil is typically refined using the same process as described above. This refining process involves additional heat from steam (again, exempting it from the “cold pressed” claim) and the use of a natural earthen bleaching clay.

Cold-Pressed Oils

• Details: Cold pressing uses a pressure method to extract the oil, but during the process, it does not use any additional chemicals, like some other processes do in order to obtain larger quantities of oil. Cold processed oils cannot exceed 122°F during the extraction process. This means that vs. expeller pressed, a cold pressed oil extraction method allows for the natural enzymes to stay intact and maintains a higher level of nutrients.
• Positives: Cold pressed oils are made without using heat so they retain their unrefined healthy antioxidants that would otherwise be lost in the refining process. Cold pressed coconut oil has more nutrients and thus, is better served raw or on lower heat.
• Negatives: Cold pressing is the least efficient method, leaving much of oil in the fruit/nuts/seeds. Cold pressed oils are generally higher in price.
• Ingredients or materials: Both expeller pressed coconut oil and cold pressed coconut oil require coconut meat (the fleshy part of the coconut!) and use the same ingredients since neither process requires chemicals or added substances[[3]](https://thecoconutmama.com/expeller-pre...
