Embodiment 1
[0044] Pullulan Hollow Hard Capsules
[0045] First, prepare the following raw materials: 7600 g of pullulan, 50 g of low acyl gellan gum, 5 g of methylglycylaminoproline, and 30000 g of purified water.
[0046] The preparation method is as follows: add 30,000 g of water at 85°C to the sol tank, turn on the mixer, stir at a speed of 50 rpm, add 50 g of low-acyl gellan gum and 5 g of methylglycyl aminoproline into the water, stir until uniformly dispersed and dissolved; Continue to stir at 50 rpm, add 7600g of pullulan polysaccharide while stirring until it is completely dissolved, keep the glue solution at 80°C for 4 hours, and vacuumize it at a vacuum pressure of 0.04MPa for 30min; control the temperature of the glue solution to 45°C, measure The gelation time was 25 seconds; the rubber was formed by dipping the rubber mold into the rubber, and dried at 27°C for 100 minutes to obtain the pullulan hollow hard capsules.
Embodiment 2
[0048] Pullulan Hollow Hard Capsules
[0049] First, prepare the following raw materials: 8000 g of pullulan, 150 g of high acyl gellan gum, 6 g of methylglycylaminoproline, and 40000 g of purified water.
[0050] The preparation method is as follows: add 40,000 g of water at 85°C to the sol tank, turn on the mixer, and stir at a speed of 60 rpm, add 150 g of high acyl gellan gum and 6 g of methylglycylaminoproline into the water, stir until uniformly dispersed and dissolved; Continue to stir at 50 rpm, add 8000g of pullulan polysaccharide while stirring, until it is completely dissolved, keep the glue at 70°C for 8h, and vacuumize it at a vacuum pressure of 0.03MPa for 40min; control the temperature of the glue to 35°C, measure The gelation time was obtained as 16S; the rubber was formed by dipping the mold with glue, and dried at 27°C for 180 minutes to obtain the pullulan hollow hard capsules.
Embodiment 3
[0052] Pullulan Hollow Hard Capsules
[0053] First, prepare the following raw materials: 8000 g of pullulan, 120 g of low-acyl gellan gum, 10 g of methylglycylaminoproline, 5 g of stearic acid, and 35000 g of purified water.
[0054] The preparation method is: add 35,000g of 82°C water to the sol tank, turn on the mixer, and stir at a speed of 55 rpm, add 120g of low-acyl gellan gum, 10g of methylglycyl aminoproline and 5g of stearic acid into the water, and stir until Disperse evenly and dissolve; continue to stir at 55 rpm, add 8000g of pullulan polysaccharide while stirring until completely dissolved, keep the glue at 75°C for 6 hours, and vacuum at a vacuum pressure of 0.04MPa for 20min; control the temperature of the glue The temperature was 55°C, and the measured gel time was 24S; dip the mold with glue to form a rubber skin, and dry it at 28°C for 150 minutes to obtain a pullulan hollow hard capsule.
