Abstract

The invention discloses a method for extracting nutmeg oil by supercritical carbon dioxide. The method uses the supercritical carbon dioxide for extracting fat-soluble ingredients in nutmeg, and then uses the difference of the solubility of the supercritical carbon dioxide in a first stage rectifying column for separation, and finally the separation and refining is carried out in a second stage separator. The extraction and precision separation of nutmeg aromaticity ingredient nutmeg oil is disposably carried out. The dehydration and impurity removal can be simultaneously carried out in the process of separation. The obtained nutmeg oil product is characterized by aromatic flavor, comprehensive ingredients, good product quality, difficult degradation of active ingredient and high product yield without containing waxiness component, solid content, organic solvent, agriculture remanet and heavy metal pollution and is convenient for large scale commercial process. The extractive is easy to be conserved after dehydration and refining removal of impurities.

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 ...
