Evening Primrose Oil Extraction Method

Lots of other evening primrose oils are obtained through “cold-pressing” extraction method which requires to press the evening primrose plant seeds by high pressure. In fact, this process is exclusively suitable for materials containing between 40-50 percent oil. Otherwise, it has a negative outcome if used on materials with moderate oil percentage amount of between 20–25 percent, just like the evening primrose. Although the raw material is not heated for squeezing, but the oil from compression is at around 150°C, which is very “unhealthy”. In other words, the quality of oil obtained by this method is very poor and worsens with exposure to air. What\'s worse, most oils must be processed being used means, which deprived off some of its minor yet valuable components, at the same time, increase the risk of oxidation. ABC Machinery\'s unique extraction method maintains more than just the authenticity of the evening primrose oil. The end product, Efamol Pure Evening Primrose Oil, comes with four times as many antioxidants (such as phospholipids, vitamin E, and sterols) compared to refined and pressed alternatives.
