Embodiment 1
[0025] Add 300 g of glycine to water for injection, heat and stir in a hot water bath to completely dissolve it, and at the same time, feed nitrogen. Add cysteine hydrochloride 0.2g, edetate disodium 0.5g, methyl p-hydroxybenzoate 0.5g, vitamin C sodium 113g, folic acid 0.4g, thiamine nitrate 3.1g, riboflavin sodium phosphate 4.9g, vitamin B 6 4.9g, biotin 60mg, vitamin B 12 5.0mg, sodium pantothenate 16.5g, nicotinamide 40g, stir to dissolve. Adjust the pH to 5.6-6.1 with sodium bicarbonate, add water for injection to the full amount, stir for 2 hours, and filter aseptically with a 0.20 μm filter element. Filling, 2.5ml per bottle, pre-freezing at -35°C for 10 hours, vacuuming, and then repressurizing with nitrogen, then pre-freezing for 3 hours, vacuuming, raising the temperature to 30°C, holding for 10 hours, and the freeze-drying is complete. Inflate nitrogen until the vacuum degree is 4000 Pa, press the plug, and roll the cap to obtain the water-soluble vitamin for i...
Embodiment 2
[0027] Add 300 g of glycine to water for injection, heat and stir in a hot water bath to completely dissolve it, and at the same time, feed carbon dioxide gas. Add cysteine hydrochloride 0.2g, edetate disodium 0.5g, methyl p-hydroxybenzoate 0.5g, vitamin C sodium 113g, folic acid 0.4g, thiamine nitrate 3.1g, riboflavin sodium phosphate 4.9g, vitamin B 6 4.9g, biotin 60mg, vitamin B 12 5.0mg, sodium pantothenate 16.5g, nicotinamide 40g, stir to dissolve. Adjust the pH to 5.6-6.1 with sodium bicarbonate, add water for injection to the full amount, stir for 2 hours, and filter aseptically with a 0.20 μm filter element. Filling, 2.5ml per bottle, pre-freezing at -40°C for 5 hours, vacuuming, and then repressurizing with carbon dioxide gas, pre-freezing for 3 hours, vacuuming, raising the temperature to 35°C, keeping it warm for 6 hours, and the freeze-drying is complete. Inflate carbon dioxide gas to a vacuum degree of 6000 Pa, press the plug, and roll the cap to obtain the w...
