Example Embodiment

[0025] Example 1:

[0026] 1. After the fermented marigold particles are dried at room temperature, they are crushed by a grinder.

[0027] 2. Load 200g of the crushed marigold raw material into the extractor, use supercritical carbon dioxide with a purity of 99%, at an extraction temperature of 40°C, a pressure of 35MPa, and CO 2 Extraction for 11h under the condition of flow rate 10L / h, separation I temperature 45℃, separation pressure 10MPa, separation II temperature 25℃, pressure and the same storage tank, a total of 19.0g marigold oleoresin.

[0028] 3. The marigold oleoresin obtained in the separation I was measured for the content of lutein by the FAO method, and the lutein was calculated to be 750.36 mg.

Example Embodiment

[0029] Example 2:

[0030] 1. After the marigold particles granulated after fermentation are dried at room temperature, they are crushed by a grinder.

[0031] 2. Load 200g of the crushed 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, and CO 2 Under the condition of a flow rate of 10L / h, extraction was performed for 11 hours, separation I temperature was 50°C, separation pressure was 12MPa, separation II temperature was 25°C, and the pressure was the same as the storage tank. A total of 20.2g marigold oleoresin was separated.

[0032] 3. The lutein content of marigold oleoresin obtained in separation I was measured by the FAO method, and the lutein was calculated to be 1023.56 mg.

Example Embodiment

[0033] Example 3:

[0034] 1. After the marigold particles granulated after fermentation are dried at room temperature, they are crushed by a grinder.

[0035] 2. Load 200g of the crushed 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, and CO 2 Extraction for 9 hours at a flow rate of 15L / h, separation I temperature 60℃, separation pressure 10MPa, separation II temperature 20℃, and the same pressure as the storage tank, a total of 18.776g marigold oleoresin was separated.

[0036] 3. The marigold oleoresin obtained from the separation I was used to measure the lutein content by the FAO method, and the lutein was calculated to be 836.23 mg.

Abstract

The invention relates to a method for using above-critical carbon dioxide to extract Tagetes lutein in the field of chemical, foods and health food process applied technology. It also relates to a new type of green entrainer: vegetable oil which can improve the lutien extracting ratio without the organic solvent residual.

Description

Technical field: [0001] The invention relates to the technical field of processing and application of medicine, food and health food, and belongs to a method for extracting lutein from marigolds with supercritical carbon dioxide. Background technique [0002] With the deepening of doubts about the safety of synthetic pigments and the sharp decline in the varieties of synthetic pigments, people's enthusiasm for traditional natural pigments has risen again. In the past 20 years, edible natural pigments in various countries in the world have achieved rapid development, new resources have been continuously excavated, new varieties have emerged, new technologies have been continuously applied, and people's consumption of edible natural pigments has continued to increase. [0003] The pigments in marigold flowers are carotenoid compounds, mainly lutein and its esters, which have been widely used in the food industry as colorants and are one of the ideal natural food pigments.
