Embodiment 1

[0016] S1 Put the cinnamon into a dryer, dry it at 50°C, and then crush it to 5 mesh;

[0017] S2 Put the obtained cassia bark powder in an extraction kettle, put carbon dioxide into it, and extract at a pressure of 30 MPa and a temperature of 50°C. The flow rate of the carbon dioxide fluid is 15 L / h, and then undergoes primary separation and secondary separation. The pressure of the primary separation is 7MPa, the temperature is 40°C, the secondary separation pressure is 5MPa, the temperature is 25°C, and the cinnamon essential oil is obtained;

[0018] S3 Filter the cinnamon essential oil with qualitative filter paper first, and then filter it with an organic microporous membrane to obtain high-purity cinnamon essential oil.

Embodiment 2

[0020] S1 Put the cinnamon into a dryer, dry it at 60°C, and then crush it to 20 mesh;

[0021] S2 Put the obtained cassia bark powder in an extraction kettle, put carbon dioxide into it, and extract at a pressure of 45MPa and a temperature of 70°C. The flow rate of the carbon dioxide fluid is 20L / h, and then undergoes primary separation and secondary separation. The pressure of the primary separation is 10MPa, temperature is 65°C, secondary separation pressure is 8MPa, temperature is 55°C, cinnamon essential oil is obtained;

[0022] S3 Filter the cinnamon essential oil with qualitative filter paper first, and then filter it with an organic microporous membrane to obtain high-purity cinnamon essential oil.

Embodiment 3

[0024] S1 Put the cinnamon into a dryer, dry it at 55°C, and then crush it to 15 mesh;

[0025] S2 Put the obtained cassia bark powder in an extraction kettle, put carbon dioxide into it, and extract at a pressure of 40 MPa and a temperature of 60 ° C. The flow rate of the carbon dioxide fluid is 18 L / h, and then undergoes primary separation and secondary separation. The pressure of the primary separation is 9MPa, the temperature is 55°C, the secondary separation pressure is 7MPa, and the temperature is 40°C, the cinnamon essential oil is obtained;

[0026] S3 Filter the cinnamon essential oil with qualitative filter paper first, and then filter it with an organic microporous membrane to obtain high-purity cinnamon essential oil.

Abstract

The invention relates to the field of essential oil extraction, and particularly relates to a method for supercritical extraction of cassia bark essential oil. The method comprises the following steps: S1, putting cassia barks in a drying machine for drying, and then crushing the cassia barks; S2, putting the obtained cassia bark powder in an extraction kettle, feeding carbon dioxide, extracting, and then carrying out primary separation and secondary separation, so that cassia bark essential oil is obtained; and S3, filtering the cassia bark essential oil by using qualitative filter paper firstly, and then filtering the cassia bark essential oil by using an organic microporous filter membrane, so that high-purity cassia bark essential oil is obtained. The method disclosed by the invention is simple and reasonable in process, high in extraction yield of products, and high in purity; the application of a large number of organic solvents is avoided, so that the obtained cassia bark essential oil is non-toxic and purely natural; and the obtained cassia bark essential oil does not contain resin ingredients, therefore, the cassia bark essential oil is good in quality, rich in fragrance, comprehensive in effective ingredients, and high in edible and medical values.

Description

technical field [0001] The invention relates to the field of essential oil extraction, in particular to a method for supercritically extracting cassia bark essential oil. Background technique [0002] Cinnamon bark, scientific name: Chaigui, also known as: cinnamon, official laurel or cinnamon, is a general name for the bark of lauraceae, camphor plants such as Tianzhugui, Yinxiang, fine-leaved cinnamon, cinnamon or Sichuan osmanthus. This product is a commonly used traditional Chinese medicine, and it is also a food spice or cooking seasoning. It is one of the most important spices in Chaoshan brine. The original plants of commercial cinnamon bark are more complicated, and there are about ten species, all of which are plants of the genus Lauraceae. There are 8 kinds commonly used in various places, mainly osmanthus osmanthus, blunt leaf osmanthus, yinxiang and Huanan osmanthus, etc. Other types are mostly used in regional medicines. Various varieties were used as spices i...
