Problems solved by technology

However, the existing methods for producing gamma-linolenic acid are nothing more than plant extraction and biological fermentation. No matter the extraction process is different or the equipment is good or bad, the pure content of one-time extraction of gamma-linolenic acid does not exceed 15%.
And the extraction method is cumbersome, requiring complex process and high equipment requirements

Embodiment 1

[0049] Collect 6 tons of pine nuts, after screening, winnowing, and flotation, remove impurities, earth, stones, fine sand, dust, empty shells, and tail fins, then dry them at 40°C, press them with a flaking machine, and press oil with a screw The machine repeatedly squeezes to obtain crude oil, and the oil extraction rate is above 70%. The crude oil was filtered with a plate and frame filter press to remove impurities, added a phosphoric acid solution with a mass fraction of 5% and a citric acid solution with a mass fraction of 10%, mixed evenly at 25°C and allowed to settle for 4 hours, separated the oil layer, and dried in vacuo to obtain Degummed oil; then add 7% sodium hydroxide solution, deacidify at 60°C, make the acid value reach 1.5mg KOH / g, add hot water at 50°C to wash, drain after 6 hours of precipitation; add 10% sodium hydroxide again Solution, deacidify at 60°C to make the acid value reach 1.0mg KOH / g, add hot water at 50°C to wash, drain after 6 hours of precip...

Embodiment 2

[0057] Collect 5 tons of pine nuts, remove impurities, soil stones, fine sand, dust, empty shells, and tail fins after screening, winnowing, and flotation, then dry them at 50°C, press them with a flaking machine, and press them with double pendulums. The oil machine is repeatedly squeezed to obtain crude oil, and the oil extraction rate is above 70%. The crude oil was filtered with a box-type filter press to remove impurities, added a phosphoric acid solution with a mass fraction of 5% and a citric acid solution with a mass fraction of 10%, mixed evenly at 60°C and allowed to settle for 4 hours, separated the oil layer, and dried in a vacuum to obtain Degummed oil; then add 7% sodium hydroxide solution, deacidify at 60°C, make the acid value reach 1.2mg KOH / g, add 50°C hot water to wash, drain after 6 hours of precipitation; add 10% sodium hydroxide again Solution, deacidify at 60°C to make the acid value reach 0.6mg KOH / g, add hot water at 50°C to wash, drain after 6 hours o...

Embodiment 3

[0064] Collect 5 tons of pine nuts, after screening, winnowing, and flotation, remove impurities, earth, rocks, fine sand, dust, empty shells, and tail fins, then dry them at 60°C, press them with a flaking machine, and press them with double pendulums. The oil machine is repeatedly squeezed to obtain crude oil, and the oil extraction rate is above 70%. The crude oil was filtered with a box-type filter press to remove impurities, added a phosphoric acid solution with a mass fraction of 5% and a citric acid solution with a mass fraction of 10%, mixed evenly at 60°C and allowed to settle for 4 hours, separated the oil layer, and dried in a vacuum to obtain Degummed oil; then add 7% sodium hydroxide solution, deacidify at 60°C, make the acid value reach 1.3mg KOH / g, add hot water at 50°C to wash, drain after 6 hours of precipitation; add 10% sodium hydroxide again Solution, deacidify at 60°C to make the acid value reach 0.7mg KOH / g, add hot water at 50°C to wash, drain after 6 ho...

Description

technical field [0001] The invention relates to the field of plant extracts, in particular to a pine nut extract. Background technique [0002] Pine nuts are the seeds of the precious tree species Korean pine. It is mainly distributed in the Changbai Mountains and Xiaoxing'anling forest areas in the northeast of my country. It is a national first-class endangered species. The wild Korean pine needs to grow for 50 years before it starts to set seeds, and the maturity period is about two years. So extremely precious. Its seeds are large and its kernels are delicious. It is known as "longevity fruit" and "longevity fruit", and is favored by people for its high nutritional value. It has a long history of eating and is a pollution-free high-grade organic green food. [0003] According to relevant data, the oil content of Korean pine nuts is as high as 78%, the protein is 14.8%, and contains a variety of vitamins. It is a valuable woody oil and health food. Pine nuts are rich ...
