Embodiment 1
[0013] 10 kilograms of fresh carrots were shredded, dried in the air, dried at 50° C. until the water content was 3%, and pulverized to obtain 1.2 kilograms of carrot dry powder. Get 800g of carrot powder and pack it into a supercritical extraction tank, and add 100g of 95% edible alcohol to the carrot powder as an entrainer to carry out supercritical extraction of carbon dioxide. The pressure of the extraction tank is 15Mpa, the extraction temperature is 35°C, the pressure of the separation tank is 8Mpa, and the separation temperature is 60°C. After the product is no longer separated from the separation tank, the extraction is stopped to obtain 85 g of carrot supercritical extract.
[0014] Add 95% ethanol to the carrot supercritical extract obtained above to dilute to 1000ml, mix evenly and put it into a 2000ml three-neck flask, slowly add 20ml hydrogen peroxide dropwise, heat and reflux for 5 hours to obtain the oxidation product. Add 0.5 g of sodium borohydride to the oxi...
Embodiment 2
[0017] 10 kilograms of fresh carrots were shredded, dried in the air, dried at 50° C. until the water content was 3%, and pulverized to obtain 1.2 kilograms of carrot dry powder. Get 800g of carrot powder and pack it into a supercritical extraction tank, and add 150g of 95% edible alcohol to the carrot powder as an entrainer to carry out supercritical extraction of carbon dioxide. The pressure of the extraction tank is 25Mpa, the extraction temperature is 45°C, the pressure of the separation tank is 7Mpa, and the separation temperature is 60°C. After the product is no longer separated from the separation tank, the extraction is stopped to obtain 140 g of carrot supercritical extract.
[0018] Add 95% ethanol to the carrot supercritical extract obtained above to dilute to 1000ml, mix evenly and put it into a 2000ml three-necked flask, slowly add 20ml hydrogen peroxide dropwise, heat and reflux for 7 hours to obtain the oxidation product. Add 0.8 g of sodium borohydride to the ...
Embodiment 3
[0021] 10 kilograms of fresh carrots were shredded, dried in the air, dried at 50° C. until the water content was 3%, and pulverized to obtain 1.2 kilograms of carrot dry powder. Get 800g of carrot powder and pack it into a supercritical extraction tank, and add 200g of 95% edible alcohol to the carrot powder as an entrainer to carry out supercritical extraction of carbon dioxide. The pressure of the extraction tank is 30Mpa, the extraction temperature is 50°C, the pressure of the separation tank is 6Mpa, and the separation temperature is 60°C. After the product was no longer separated from the separation tank, the extraction was stopped to obtain 181 g of carrot supercritical extract.
[0022] Add 95% ethanol to the carrot supercritical extract obtained above to dilute to 1000ml, mix evenly, put it into a 2000ml three-necked flask, slowly add 20ml hydrogen peroxide dropwise, and heat to reflux for 7 hours to obtain the oxidation product. Add 1 g of sodium borohydride to the ...
