Problems solved by technology

[0003] However, vitamin C is very unstable in aqueous solution. Vitamin C is prone to oxidation reaction in the presence of oxygen, and light, heat, alkali and metal ions, especially iron ions and copper ions, can accelerate the oxidation reaction. Occurrence will cause vitamin C to lose its efficacy; at the same time, the internal aliphatic ring in the vitamin C molecule can be hydrolyzed and further reacted to form furfural, resulting in oxidative polymerization and a yellow color
However, the structure of vitamin C cannot be changed in production, and the oxidation and hydrolysis reactions can only be inhibited by improving the process.

Abstract

The invention relates to the technical field of vitamin C injections, and specifically provides a control method for anti-oxidation of a vitamin C injection. The method comprises the following steps:(1) quality control of the raw material medicine vitamin C and auxiliary materials; (2) cleaning and drying of ampoule bottles; (3) preparation: the raw material vitamin C and auxiliary materials areadded according to the prescription dosage to prepare a liquid medicine; (4) fine filtration: filtration is performed through a 0.22 micron microporous membrane cartridge filter; (5) potting; (6) sterilization: the sterilization condition is 100 DEG C and 9 min. After sterilization, spray equipment is turned on to cool the ampoule bottles. The raw material is strictly controlled, and the process is adjusted and optimized. After the vitamin C injection produced by the above control method is detected through an acceleration test and a long-term stability test, various properties all meet the standard requirements, stability of the product is improved, and production efficiency of the optimized process and qualified rate of the finished product are both obviously improved.

Description

technical field [0001] The invention relates to the technical field of vitamin C injection, in particular to a method for controlling oxidation prevention of vitamin C injection. Background technique [0002] Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that can promote the biosynthesis of collagen, facilitate faster healing of tissue wounds, improve the metabolism of fats and lipids, especially cholesterol, prevent cardiovascular diseases, and enhance the body's ability to respond to the outside world. Environmental resilience and immunity. [0003] However, vitamin C is very unstable in aqueous solution. Vitamin C is prone to oxidation reaction in the presence of oxygen, and light, heat, alkali and metal ions, especially iron ions and copper ions, can accelerate the oxidation reaction. Occurrence will cause vitamin C to lose its efficacy; at the same time, the internal aliphatic ring in the vitamin C molecule can be hydrolyzed and further reacted to ...
