Examples
Embodiment 1
[0026] 1. After the fermented and granulated marigold granules are dried at room temperature, they are pulverized by a pulverizer.
[0027] 2. Put 200 g of crushed marigold raw materials into the extractor, use supercritical carbon dioxide with a purity of 99%, extract at 40°C at an extraction temperature of 35 MPa, and CO 2 Extract for 11 hours under the condition of flow rate 10L / h, separation I temperature 45°C, separation pressure 10MPa, separation II temperature 25°C, same pressure as the storage tank, and a total of 19.0g marigold oleoresin was obtained.
[0028] 3. Measure the lutein content by the marigold oleoresin obtained from the separation I by the FAO method, and calculate that the lutein is 750.36 mg.
Embodiment 2
[0030] 1. After the fermented and granulated marigold granules are dried at room temperature, they are pulverized by a pulverizer.
[0031] 2. Put 200g of the pulverized marigold raw material into the extractor, use supercritical carbon dioxide with a purity of 99%, at a temperature of 50°C, a pressure of 30MPa, CO 2 Under the condition of flow rate 10L / h, extract for 11h, separation I temperature is 50°C, separation pressure is 12MPa, separation II temperature is 25°C, the pressure is the same as that of the storage tank, and a total of 20.2g of marigold oleoresin is separated.
[0032] 3. Measure the lutein content by the marigold oleoresin obtained from the separation I by the FAO method, and calculate that the lutein is 1023.56 mg.
Embodiment 3
[0034] 1. After the fermented and granulated marigold granules are dried at room temperature, they are pulverized by a pulverizer.
[0035] 2. Put 200g of the pulverized marigold raw material into the extractor, use supercritical carbon dioxide with a purity of 99%, at a temperature of 45°C, a pressure of 35MPa, CO 2 Extracted for 9 hours under the condition of flow rate 15L / h, separation I temperature was 60°C, separation pressure was 10MPa, separation II temperature was 20°C, and the pressure was the same as that of the storage tank. A total of 18.776g of marigold oleoresin was isolated.
[0036] 3. Measure the lutein content by the marigold oleoresin obtained from the separation I by the FAO method, and calculate that the lutein is 836.23 mg.
