Embodiment 1

[0018] 1) Remove impurities and shells from the picked seaside mallow seeds, put them in an oven at 45°C for 5 hours, take them out, and crush them into 50-mesh powder with crushing equipment for later use.

[0019] 2) Fill the powder prepared in (l) into a twin-screw cold press to extract oil, and filter to obtain seashore mallow seed crude oil.

[0020] 3) Carry out the first molecular distillation of seashore mallow seed crude oil obtained in (2), set the scraping film speed to 289r / min, cooling water temperature to 12°C, distillation temperature to 50°C, distillation pressure to 0.11 kPa, and material flow rate 14 mL / min. The primary seaside mallow seed essential oil is finally obtained in the heavy phase collection tank.

[0021] 4) Carry out the second molecular distillation of the primary seaside mallow seed essential oil obtained in (3), reset the scraping film speed to 300 r / min, cooling water temperature to 12 °C, distillation temperature to 55 °C, distillation pres...

Embodiment 2

[0023] 1) Remove impurities and shells from seaside mallow seeds, put them in an oven at 60 ℃ for 4 hours, take them out, and crush them into 45-mesh powder with crushing equipment for later use.

[0024] 2) Fill the powder prepared in (l) into a twin-screw cold press to extract oil, and filter to obtain seashore mallow seed crude oil.

[0025] 3) Carry out the first molecular distillation of seashore mallow seed crude oil obtained in (2), set the scraping film speed to 460 r / min, the cooling water temperature to 35 °C, the distillation temperature to 75 °C, the distillation pressure to 0.21 kPa, and the material Flow rate 8 mL / min. The primary seaside mallow seed essential oil is finally obtained in the heavy phase collection tank.

[0026] 4) Carry out the second molecular distillation of the essential oil obtained in (3), reset the scraping film speed to 480 r / min, the cooling water temperature to 30 °C, the distillation temperature to 70 °C, the distillation pressure to 0...

Abstract

The invention discloses a preparation method of kosteletzkya virginica seed essential oil. The methods of drying, crushing, cold squeezing and secondary molecular distillation are used for collection to obtain the kosteletzkya virginica seed essential oil. When the method is used for extracting the kosteletzkya virginica seed essential oil, simplicity is realized; the operation is easy; the cost is low; the extraction efficiency is high; in addition, no organic solvent is remained.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a preparation method of seaside mallow seed essential oil. Background technique [0002] Seashore mallow (Kosteletzkya virginica L.) is a perennial perennial plant of Malvaceae, which is naturally distributed in the salt marsh coastal zone from Delaware to Texas along the eastern coast of the United States. Seashore mallow was introduced from the United States by Professor Admiration of Nanjing University in 1993, and has been widely promoted and planted in coastal areas of my country. Existing research shows that seaside mallow seaside mallow has a seed yield of about 800~1500 kg / hm in the United States 2 , The oil content is 22%. It also contains rich nutrients, such as protein content as high as 27.4% ~ 29.6%, of which grain crude protein is about 24%; it also contains glutamic acid, aspartic acid and arginine and other amino acids, and the content of unsaturated fat...
