Chitosan is a biodegradable natural polymer material with good biocompatibility and biodegradability, so it is widely used in fields such as medicine, food, and cosmetics. To better protect and store chitosan, we need to take some measures and methods. This article will introduce several common storage methods for chitosan.
Dry Storage Method
Chitosan is very sensitive to humidity, so it is very important to maintain a low – humidity environment during storage. Chitosan can be stored in a dry environment using sealed plastic bags or containers. Before putting chitosan in, some desiccants, such as silica gel, can be placed in the container to absorb moisture in the humid air. At the same time, avoid exposure to direct sunlight to prevent chitosan from getting damp.
Low – Temperature Storage Method
Chitosan is prone to decomposition and degradation in a high – temperature environment, so high temperatures should be avoided as much as possible during storage. It is best to store chitosan in a low – temperature environment, such as a refrigerator or freezer. This can effectively extend the shelf life of chitosan and maintain its good performance.
Light – Shielding Storage Method
Chitosan is also very sensitive to light and is prone to degradation under the influence of ultraviolet rays. Therefore, when storing chitosan, direct sunlight should be avoided. You can choose to use opaque containers to store chitosan or place it in a dark environment.
Pest – Prevention Storage Method
Chitosan is prone to being infested by pests during storage, so pest – prevention measures need to be taken. Some pest – repellents, such as camphor balls or lavender, can be placed around chitosan to prevent the occurrence of pests. At the same time, regularly check the storage status of chitosan to ensure that there are no pests.
Sub – packaging Storage Method
If chitosan needs to be stored for a long time, it can be considered to be sub – packaged into small packages or small containers. This can avoid repeatedly opening large packages, reducing the exposure and contamination of chitosan. At the same time, it is also more convenient for use and management.
Regular Inspection and Maintenance
When storing chitosan, it is very important to regularly check its storage status. Check for moisture, discoloration, deterioration, and other situations. If abnormalities are found, they should be handled and replaced in a timely manner. At the same time, regularly clean the storage environment to keep it dry, clean, and tidy.
