Embodiment 1

[0023] Referring to the above extraction method: put 450g of commercially available nutmeg ground raw materials into the extraction kettle, keep the extraction pressure at 7MPa, and the extraction temperature at 40°C; 13.5g of milky white paste solid extract can be obtained; the pressure of the second stage separator is 5MPa, and the separation temperature is 25°C, 62.2g of light yellow liquid nutmeg essential oil can be obtained, and the yield of nutmeg essential oil is 13.8%. The product quality and yield of nutmeg essential oil are obviously higher than other methods.

Embodiment 2

[0025] Refer to the above extraction method: put 490g of commercially available nutmeg ground raw materials into the extraction kettle, keep the extraction pressure at 10MPa, and the extraction temperature at 55°C; 14.5g of milky white paste solid extract can be obtained; the pressure of the second stage separator is 6MPa, and the separation temperature is 45°C, 74.5g of light yellow liquid nutmeg essential oil can be obtained, and the yield of nutmeg essential oil is 15.2%. The product quality and yield of nutmeg essential oil are obviously higher than other methods.

Embodiment 3

[0027] Refer to the above extraction method: put 500g of commercially available nutmeg into the extraction kettle, keep the extraction pressure at 20MPa, and the extraction temperature at 40°C; 74.5g of milky white paste solid extract can be obtained; the pressure of the second stage separator is 5MPa, and the separation temperature is 55°C, 85.3g of light yellow liquid nutmeg essential oil can be obtained, and the yield of nutmeg essential oil is 17.1%. The product quality and yield of nutmeg essential oil are obviously higher than other methods.

Abstract

The present invention disclosed a method of extracting carbon extract with cure carbon dioxide.The present invention uses supercritical carbon dioxide to extract the fat -soluble ingredients in Nutmectic, and then uses the difference in solubility in the supercritical carbon dioxide in the first -class distillation column to separate, and is separated and refined in the second -level separator.You can perform the extraction and precision separation of youth aromatic ingredients at one time. The extract and precision separation of meat cardamom oil can be dehydrated and dehydrated at the same time during the separation process.Good quality, no solid objects, effective ingredients are not easy to degrade, no organic solvents, no agricultural residues, and no heavy metal pollution, which is convenient for large -scale industrialized production and high income from products.After dehydration, the extract after miscellaneous treatment is easier to save.

Description

technical field [0001] The invention relates to a method for extracting nutmeg essential oil. Background technique [0002] Nutmeg is the dry seed kernel of the nutmeg plant Myristica fragrans houtt. It is warm in nature, pungent in taste, and returns to the spleen, stomach, and large intestine meridians. Warming middle-JIA and promoting qi, astringent intestines for relieving diarrhea. For spleen and stomach deficiency and cold, chronic diarrhea, abdominal distension and pain, and vomiting due to lack of food. It is mainly produced in Malaysia, Indonesia, Sri Lanka and other countries. In addition, it is also produced in the West Indies. In addition, in the past, my country only cultivated nutmeg in Taiwan, Yunnan and other places. In recent years, it has been successfully introduced in a large area in Hainan, but most of the medicinal materials are imported. Nutmeg essential oil is a volatile oil extracted from nutmeg, which is its main active ingredient. In addition to ...
