Embodiment 1
[0029] Using the fruit of Jindenglong as raw material, zeaxanthin was prepared according to the following process:
[0030] Take 1000 grams of Jindeng fruit, freeze-dry, grind into powder, pass through a 100-mesh sieve, take the powder under the sieve, and add ethanol-cyclohexane solution containing 10% KOH in the ratio of Jindeng mass:solvent volume=1g:10ml (Ethanol: non-polar organic solvent volume ratio 1:1) 10 liters, stirred at 30°C for extraction and saponification for 2 hours; after the extraction, stand still for precipitation and separation; obtain the extract and filter residue;
[0031] Add 10 liters of the above ethanol-cyclohexane solution containing 10% KOH to the filter residue again for the second extraction and saponification; stir extraction and saponification at 30°C for 2 hours; stand for precipitation and separation after extraction; obtain the extract and filter residue;
[0032] Add 10 liters of the above ethanol-cyclohexane solution containing 10% KOH t...
Embodiment 2
[0036] Using Jindenglong persistent calyx as raw material, zeaxanthin was prepared according to the following process:
[0037] Take 1000 grams of persistent calyx, freeze-dry, grind into powder, pass through a 100-mesh sieve, take the powder under the sieve, add ethanol-cyclohexane solution containing mass concentration 10% KOH according to the ratio of persistent calyx mass:solvent volume=1g:50ml ( Ethanol: non-polar organic solvent (volume ratio 1:1) 50 liters, 30 ° C stirring extraction, saponification for 2 hours; after the extraction, stand still for precipitation and separation; obtain the extract and filter residue;
[0038]Add 50 liters of the above ethanol-cyclohexane solution containing 10% KOH to the filter residue again for the second extraction and saponification; stir extraction and saponification at 30°C for 2 hours; after the extraction, let it stand for precipitation and separation; obtain the extract and filter residue;
[0039] Add 10 liters of the above et...
