Supercritical CO2 extraction of vanilla orchid pods

CO2 extraction method/process of vanilla oil

Supercritical CO2 extraction machine L-05

1.Crush to obtain powder, about 85 grams

Supercritical CO2 extraction of vanilla essential oil


2.Low pressure (14MPa) extraction for 25 minutes

Separate the kettle to obtain a light yellow liquid

Nothing obtained from the second separation kettle

3.Medium pressure (20MPa) extraction for 20 minutes

Separate kettle 2 to obtain a small amount of white liquid

4.High pressure (28MPa) extraction for 20 minutes

Separating kettle 1 and separating kettle 2 did not get any material

Name Crushed vanilla Separate the extract of kettle one Separate the extract of kettle twoWeight About 85g 5g 3g Total: 8g

Notes:

The extract was 93 grams, which was only 85 grams after crushing.The final separation tank 1 obtained only 5 grams. Because there are too few extraction materials available for testing, the test data may be inaccurate (the machine nozzle and pipeline will have extraction liquid residue, weighing and measurement errors), and the best test volume is recommended 2 kg of raw materials.

Our company has done Hainan vanilla extraction for a research in Hainan Province, China, and the final separation-extraction rate is about 5-8%;

After testing, we agreed that the raw material extract in this test has a higher yield than Hainan’s vanilla
