[0023] Example 1
[0024] A method for comprehensively extracting aroma components in agarwood, comprising the following steps:
[0025] (1) Raw material selection: Choose agarwood that has grown for more than 16 years and has oil threads as raw materials for backup;
[0026] (2) Raw material pretreatment: crush the agarwood selected in step (1) at a temperature of 20-30℃, and then weigh the undersize after passing through a 40-mesh sieve; to the weighed undersize Add the compound enzyme preparation and water, adjust the moisture content to 15%, react for 48 hours at a temperature of 25°C, and air dry to obtain agarwood powder for later use;
[0027] (3) Supercritical CO 2 Extraction: Weigh the agarwood powder obtained in step (2), add absolute ethanol as an entrainer, mix it evenly, add it to the extraction kettle, and input supercritical CO into the extraction kettle 2 The fluid is extracted under the conditions of an extraction pressure of 45MPa and an extraction temperature of 50℃...
