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.

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.
