Examples
Embodiment 1
[0029] Weigh 10g of PEG-400 and place it in a flask, add 100g of methanol, fully dissolve it in a water bath at 25°C and mix evenly to obtain a methanol solution containing PEG-400. Weigh 3.33g of edible paraffin, heat the paraffin to melt it completely, add 10g of vitamin C while it is hot and stir evenly to obtain a mixture of vitamin C and edible paraffin. Add the obtained vitamin C and edible paraffin mixture to the PEG methanol solution while hot, and keep stirring at 70°C for 30 minutes. Heating and stirring were stopped, and the mixture was naturally cooled to room temperature under reflux to obtain a suspension containing solids. After the suspension was completely cooled, the supernatant was removed by filtration, and the obtained solid was rinsed with methanol for 3 to 5 times, dried under reduced pressure, and then freeze-dried to obtain 11 g of vitamin C microcapsules I.
Embodiment 2
[0031] Weigh 10g of PEG-400 and place it in a flask, add 250g of methanol, fully dissolve it in a water bath at 35°C and mix evenly to obtain a methanol solution containing PEG-400. Weigh 10 g of edible paraffin, heat the paraffin to melt it completely, add 20 g of vitamin C while it is hot and stir evenly to obtain a mixture of vitamin C and edible paraffin. Add the obtained vitamin C and edible paraffin mixture to the PEG methanol solution while hot, and keep stirring at 70°C for 60 minutes. Heating and stirring were stopped, and the mixture was naturally cooled to room temperature under reflux to obtain a suspension containing solids. After the suspension was completely cooled, the supernatant was removed by filtration, and the obtained solid was rinsed with methanol for 3 to 5 times, dried under reduced pressure, and then freeze-dried to obtain 17 g of vitamin C microcapsule II.
Embodiment 3
[0033] Weigh 10g of PEG-400 and place it in a flask, add 150g of methanol, fully dissolve it in a water bath at 30°C and mix evenly to obtain a methanol solution containing PEG-400. Weigh 5 g of edible paraffin, heat the paraffin to melt it completely, add 15 g of vitamin C while it is hot and stir evenly to obtain a mixture of vitamin C and edible paraffin. Add the obtained vitamin C and edible paraffin mixture to the PEG methanol solution while hot, and keep stirring at 70°C for 45 minutes. Heating and stirring were stopped, and the mixture was naturally cooled to room temperature under reflux to obtain a suspension containing solids. After the suspension was completely cooled, the supernatant was removed by filtration, and the obtained solid was rinsed with methanol for 3 to 5 times, dried under reduced pressure, and then freeze-dried to obtain 19 g of vitamin C microcapsules.
