Embodiment 1
[0033] Example 1 Propolis supercritical CO 2 Extract preparation
[0034] Supercritical CO 2 The first process condition of the extraction is: after freezing and pulverizing the propolis raw material, i.e. wool glue, use supercritical CO 2 Extraction, the pressure of the extraction tower is 29MPa, the extraction temperature is 58°C, the extraction time is 3h, the entrainer is 5% ethanol (volume concentration 95%) of the feed amount of the extraction tower, the pressure of the separation tower is 6MPa, the separation temperature is 50°C, and the material is discharged from the separation tower propolis supercritical CO 2 Extract. The second process condition is: after freezing and pulverizing the propolis raw material, i.e. hair gelatin, with supercritical CO 2 Extraction, the pressure of the extraction tower is 32MPa, the extraction temperature is 29°C, the extraction time is 6h, the entrainer is 17% ethanol (volume concentration 75%) of the feed amount of the extract...
Embodiment 2
[0035] The preparation of embodiment 2 food preservatives
[0036] Food preservation agent of the present invention is the propolis supercritical CO prepared by embodiment 1 2 The extract is the main component, and it is a composition prepared by mixing with sucrose fatty acid ester (SE-11), lecithin and ethanol or 1,2-propanediol. Among them, propolis supercritical CO 2 The extract is both a preservative, an antioxidant and a film-forming agent; sucrose fatty acid ester is an emulsifier, a preservative and a film-forming agent; lecithin is an emulsifier; ethanol (volume concentration 75-95%) or 1 , 2-propanediol is a co-solvent, and the choice of co-solvent is in accordance with the requirements of the national "Hygienic Standards for the Use of Food Additives" GB2760 according to different foods. The mass percent content of each component of the food preservative of the present invention is: propolis supercritical CO 2 Extract 10-25% (0.5-1.8% based on total flavonoids)...

[0038] Example 3 Propolis supercritical CO 2 Performance index detection of extracts
[0039] The propolis supercritical CO prepared by embodiment 1 2 The main performance indicators of the extract are shown in Table 1:
[0040]
[0041] The propolis supercritical CO prepared by Example 1 is as follows 2 Antioxidant effect of extract as food antioxidant on rapeseed oil compared with wool gum:
[0042] Under the same addition amount of 0.02% (calculated as total flavonoids) and a constant temperature of 60°C, the propolis supercritical CO prepared in Example 1 2 The antioxidant performance of the extract was significantly greater than that of wool glue. Flavonoids in propolis are one of the main antioxidant active components, and they are combined with propolis supercritical CO 2 The overall antioxidant activity of the extract showed a dose-effect relationship.
[0043] The propolis supercritical CO prepared by Example 1 is as follows 2 Extract compares the anti...
