Pine Nut Oil Extraction Technology

Pine nut oil is made from the fruit of pine nut (kernel). Pine nut oil is rich in natural vitamins and unsaturated fatty acids. Vitamins and unsaturated fatty acids are important in vegetable oils. Among the known vegetable oils, pine nut oil is the best in both the content and distribution of unsaturated fatty acids. (Related Post: Essential Oil Extraction Business Plan >>)

Pine Nut Oil Extraction Methods

The widely used pine nut oil extraction method has physical pressing and solvent extraction. But both of these two methods have its advantages and disadvantages. Physical pressing equipment is cheap and can be easily operated. But, the high temperature by frictions may destroy the original nutrients contained in the pine nut oil. While, the solvent extraction is relatively complicated and requires large amounts, but its oil yield is relatively higher. So, is there more cost effective and practical method to produce high quality pine nut oil.

Fortunately, it does have. The sub-critical low temperature extraction technology is now the most suitable oil processing technology for many valuable vegetable oils, such as pine nut oil, grape seed oil, and more. (Related Post: Avocado Oil Extraction Machine Price >>)
 

How to Extract Pine Nut Oil by Low Temperature Oil Extraction Machine?

Sub-critical low temperature extraction technology is an extraction process that uses the special properties of the above sub-critical fluid, materials are injected into the extraction tank and soaked in sub-critical fluid, assisted by a certain material solubility ratio, extraction temperature, extraction time, extraction pressure, extractant and entrainer, agitation and ultrasonic. The extraction mixture enters the evaporation system after solid-liquid separation. Under the action of compressor and vacuum pump, according to the principle of vacuum evaporation, the extractant is changed from liquid to gas to obtain the target extract.

Benefits of Pine Nut Oil

Pine nut oil contains pinolinic acid, which is not found in other vegetable oils, and several kinds of 20 carbon unsaturated fatty acids with very little content. These unsaturated fatty acids are essential components of cell membrane lipoproteins, as well as maintaining the integrity of skin barrier. In addition, unsaturated fatty acids can also inhibit the aging of the skin. The lack of unsaturated fatty acids can cause skin exfoliation and increase water loss.
