Pumpkin seed oil mainly contains 10 kinds of fatty acids, and the content of unsaturated fatty acids accounts for 90%. Among them, the content of oleic acid is as high as 63.0%, followed by linoleic acid content of 20.2%, linolenic acid content of 6.8%, palmitic acid content of 4.09%, stearic acid content of 1.78%, behenic acid content of 1.16%, and the content of other four fatty acids is very low, accounting for about 1.05% in total. Studies have shown that unsaturated fatty acids have the effects of lowering blood fat, antithrombotic, and lowering blood pressure, and their medicinal value has attracted more and more attention and application. In particular, linoleic acid and linolenic acid are essential fatty acids for the human body, which are necessary for the synthesis of phospholipids, the formation of cell structures, and the maintenance of normal functions of all tissues. In addition, linoleic acid also has the functions of preventing high cholesterol, improving high blood pressure, and preventing myocardial infarction; linolenic acid has the effects of degrading thrombus, inhibiting the occurrence of cancer, and eliminating excessive intake of linoleic acid. Therefore, pumpkin seed oil is a good nutritional and health care oil.

If the hot-pressing method is used to extract pumpkin seed oil, the pumpkin seed kernels need to be steamed and fried to 120 degrees Celsius first, and the moisture should be controlled at 1%-1.5% before pressing. The pumpkin seed oil extracted in this way must undergo refined oil treatment such as degumming, deacidification, dehydration, decolorization, and deodorization. After a systematic treatment, the pumpkin seed oil can be eaten. However, after the pumpkin seed oil is refined by this system, the nutritional value of the pumpkin seed oil will inevitably be destroyed.

Pumpkin seed oil produced by cold pressing method is to select mature pumpkin seeds, cold press and filter to obtain virgin oil. The process of producing pumpkin seed oil by cold pressing is that the oil crops are not subjected to high-temperature treatment such as steaming and frying before being pressed, and the temperature is controlled below 80 degrees Celsius. Moreover, the pumpkin seed oil and other oils produced by the cold pressing process can avoid harmful substances such as trans fatty acids and oil polymers produced during high-temperature processing, and retain the active substances in the oil.

In general, the hot-pressing method has a higher oil yield, but the oil is darker in color and will destroy the nutritional content of the oil. The cold pressing method can retain nutrients to a greater extent, but the oil yield is not high. It is recommended to choose different pressing methods according to different market demands.
