Embodiment 1
[0038] Use the following method to extract each effective active ingredient in citrus peel (ponkan peel) (the process flow is as follows: figure 1 shown):
[0039] 1) Pretreatment of citrus peels: Dry the citrus peels at 61°C, crush them, pass through a 25-mesh sieve, and then blanch them with hot water at 89°C for 13 minutes to inactivate the enzymes in the citrus peels, and then soak them in distilled water for 1.5 h, to obtain the pretreated citrus peel residue, for subsequent use.
[0040] 2) Extract essential oil: Put the pretreated citrus peel into the NaCl solution with a mass fraction of 4.5% at a mass ratio of 1:11.2, and carry out distillation extraction for 54 minutes to obtain the distilled extract and de-essentially oiled citrus peel. The above operation of distillation and extraction was repeated twice, and the distillation extracts obtained each time were combined together as the distillation extract. Then extract and distill the extract with an extractant (a ...
Embodiment 2
[0046] Use the following method to extract each effective active ingredient in citrus peel (navel orange peel) (the process flow is as follows: figure 1 shown):
[0047] 1) Pretreatment of citrus peels: Dry the citrus peels at 64°C, crush them, pass through a 20-mesh sieve, and then blanch them with hot water at 92°C for 11 minutes to inactivate the enzymes in the citrus peels, and then soak them in distilled water for 80 minutes , to obtain pre-treated citrus peel residue, and set aside.
[0048] 2) Extract essential oil: Put the pretreated citrus peel into the NaCl solution with a mass fraction of 5.0% at a mass ratio of 1:11.6, and carry out distillation extraction for 61 minutes to obtain the distilled extract and de-essentially oiled citrus peel. The above operation of distillation and extraction was repeated twice, and the distillation extracts obtained each time were combined together as the distillation extract. Then use the extractant (a mixture of ether and dichlor...
Embodiment 3
[0054] The following methods are used to extract each effective active ingredient from citrus peel (citrus peel) (the process flow is as follows: figure 1 shown):
[0055] 1) Pretreatment of citrus peels: Dry the citrus peels at 62°C, crush them, pass through a 25-mesh sieve, and then blanch them with hot water at 85°C for 12 minutes to inactivate the enzymes in the citrus peels, and then soak them in distilled water for 100 minutes , to obtain the pretreated citrus peel residue, and set aside.
[0056] 2) Extract essential oil: Put the pretreated citrus peel into the NaCl solution with a mass fraction of 4.8% at a mass ratio of 1:10.9, and carry out distillation extraction for 67 minutes to obtain the distillation extract and de-essential citrus peel. The above operation of distillation and extraction was repeated twice, and the distillation extracts obtained each time were combined together as the distillation extract. Then extract and distill the extract with an extractan...
