How long is the shelf life of sodium alginate?


Sodium alginate will inevitably pass its shelf life if it is not used for a long time. The effect and performance of sodium alginate that have passed the shelf life will often be greatly discounted. The quality and quality of sodium alginate during the shelf life can be guaranteed, but after this deadline The quality and effect of sodium alginate will gradually decrease, and expired sodium alginate is generally not recommended. So how long is the shelf life of sodium alginate?

How long is the shelf life of sodium alginate? Under normal circumstances, it has two years. Pay attention to ventilation and heat dissipation during normal storage, because sodium alginate is easy to absorb moisture and its viscosity will decrease when heated. Down to a certain level, the quality of the product itself is not a problem, but the thickening stability in the final product will be compromised.

According to research, it is found that the viscosity of sodium alginate powder is different after one year of storage at different temperatures. In general, the higher the storage temperature, the worse the stability of sodium alginate.

Under normal circumstances, use the correct storage method to store sodium alginate, which can generally be stored for 2 years. However, if sodium alginate is stored in a poorly sealed, humid, and high-temperature environment, the shelf life of sodium alginate is usually not Too long, so the correct storage method will help extend the shelf life of sodium alginate.
