Example Embodiment
[0052] Example 1
[0053] (1) The ionic liquid tributyl octyl phosphine bromide and distilled water are uniformly mixed to prepare an ionic liquid aqueous solution so that the mass fraction of the tributyl octyl phosphine bromide in the ionic liquid aqueous solution is 2%.
[0054] (2) The fresh shrimp shells are washed and freeze-dried at a freezing temperature of -50°C for 40 hours, then ground in a grinder, and then passed through a 50-mesh sieve to obtain shrimp shell powder for later use.
[0055] (3) Take 1g of the shrimp shell powder obtained in step (1) and 35g of the ionic liquid aqueous solution obtained in step (2) into a beaker, and then stir with a magnetic stirrer, set the stirring speed to 1000rpm, and stir for 60min at room temperature. Then, the obtained mixture was centrifuged at 5000 rpm for 20 minutes to obtain the supernatant of the ionic liquid aqueous solution from which astaxanthin was extracted and the astaxanthin-based shrimp shell powder precipitate, and th...

[0058] Example 2
[0059] (1) Mix the ionic liquid tributyl octyl phosphonium bromide and distilled water uniformly to prepare an ionic liquid aqueous solution, so that the mass fraction of tributyl octyl phosphonium bromide in the ionic liquid aqueous solution is 5%; Butyl octyl phosphine bromide.
[0060] (2) The fresh shrimp shells are washed and freeze-dried at a freezing temperature of -55°C for 40 hours, then ground in a grinder, and then passed through a 70-mesh sieve to obtain shrimp shell powder for later use.
[0061] (3) Take 1g of the shrimp shell powder obtained in step (1) and 30g of the ionic liquid aqueous solution obtained in step (2) into a beaker, and then stir with a magnetic stirrer, set the stirring speed to 500rpm, and stir for 120min at room temperature. Then, the obtained mixture was centrifuged at 6000 rpm for 18 minutes to obtain the supernatant of the ionic liquid aqueous solution from which astaxanthin was extracted and the astaxanthin pellets of shrimp ...

[0064] Example 3
[0065] (1) The ionic liquid tributyl octyl phosphine bromide and distilled water are uniformly mixed to prepare an ionic liquid aqueous solution, so that the mass fraction of the tributyl octyl phosphine bromide in the ionic liquid aqueous solution is 8%.
[0066] (2) The fresh shrimp shells are washed and freeze-dried at a freezing temperature of -60°C for 30 hours, then ground in a grinder, and then passed through an 80-mesh sieve to obtain shrimp shell powder for later use.
[0067] (3) Take 1g of the shrimp shell powder obtained in step (1) and 25g of the ionic liquid aqueous solution obtained in step (2) in a beaker, and then stir with a magnetic stirrer, set the stirring speed to 800rpm, and stir for 80min at room temperature. Then, the obtained mixture was centrifuged at 6000 rpm for 18 minutes to obtain the supernatant of the ionic liquid aqueous solution from which astaxanthin was extracted and the astaxanthin pellets of shrimp shell powder, and the supern...
