What are the storage requirements for ε-Polylysine hydrochloride?

ε-Polylysine hydrochloride is a food preservative that is used in a wide range of food products to extend their shelf life and prevent spoilage. Like other food preservatives, proper storage is essential to maintain its quality and effectiveness. In this article, we will discuss the storage requirements for ε-Polylysine hydrochloride.

Temperature
The most important factor in storing ε-Polylysine hydrochloride is temperature. It is recommended that the product be stored in a cool, dry place at temperatures below 25°C (77°F). This is because high temperatures can accelerate the degradation of the preservative and reduce its effectiveness. Therefore, it is important to avoid exposing the product to direct sunlight or other sources of heat.

Humidity
Humidity is another important factor in storing ε-Polylysine hydrochloride. The product should be stored in a dry environment with a relative humidity below 70%. High humidity can cause the preservative to absorb moisture and clump together, reducing its effectiveness. Therefore, it is recommended that the product be stored in an airtight container to prevent moisture from entering.

Light
Exposure to light can also affect the stability of ε-Polylysine hydrochloride. The product should be stored in a dark place to avoid exposure to UV radiation, which can cause the product to degrade and lose its effectiveness. If the product is stored in a clear container, it should be wrapped in opaque material to protect it from light.

Packaging
The packaging of ε-Polylysine hydrochloride can also affect its stability. The product should be stored in its original packaging to ensure that it is protected from moisture and light. If the original packaging has been opened, it should be resealed tightly to prevent air and moisture from entering.

Shelf Life
Finally, it is important to note the shelf life of ε-Polylysine hydrochloride. The product should be used before its expiration date, which is typically two years from the date of manufacture. After this date, the preservative may start to lose its effectiveness, and its ability to prevent spoilage may be reduced.

In conclusion, proper storage is essential to maintain the quality and effectiveness of ε-Polylysine hydrochloride. The product should be stored in a cool, dry place, away from direct sunlight and other sources of heat. It should also be stored in an airtight container to prevent moisture from entering. Additionally, the product should be used before its expiration date to ensure that it is effective in preventing spoilage. By following these storage requirements, food manufacturers can ensure that their products are safe and have a longer shelf life.
