The storage method recommended by the phospholipid manufacturer

Phospholipid manufacturers usually recommend the following ways to store phospholipids:

Temperature Control: Generally, phospholipids should be stored in a low-temperature environment, and the ideal storage temperature is between 2 and 8°C. Low temperature can reduce the oxidation rate of phospholipids, delay the deterioration process, and help maintain the stability and biological activity of phospholipids. For example, in the warehouses of some large phospholipid manufacturing enterprises, professional refrigeration equipment is equipped to maintain the appropriate storage temperature.

Humidity Management: Phospholipids are sensitive to humidity. A high-humidity environment can easily cause phospholipids to absorb moisture, thereby triggering reactions such as hydrolysis and oxidation, which affect their quality. Therefore, the relative humidity of the storage environment should be controlled at a low level, and it is generally recommended to be between 40% and 60%. To meet this requirement, dehumidification equipment may be used in the warehouse, or desiccants can be placed in the packaging of phospholipids to absorb moisture in the air.

Light-Avoiding Storage: Light can accelerate the oxidation process of phospholipids, darken their color, and reduce their quality. Therefore, phospholipids should be stored in a place away from light. It is recommended to use opaque packaging materials, such as aluminum foil bags, brown glass bottles, etc., to reduce the impact of light on phospholipids. In the warehouse, direct sunlight should also be avoided, and the time and intensity of lighting should be minimized.

Sealed Storage: Phospholipids are prone to oxidation when in contact with air, so they need to be stored in a sealed manner. Good sealing can prevent oxygen, moisture, etc. in the air from coming into contact with phospholipids and extend their shelf life. Whether it is phospholipids in large packages or small packages, if they are not used up after opening, they should be sealed in a timely manner to prevent them from being in contact with air for a long time.

Avoid Mixing with Odorous Substances: Phospholipids have a certain adsorbability and are prone to absorbing odors in the surrounding environment. Therefore, during storage, they should be kept away from odorous substances such as spices and chemicals to avoid affecting the odor and quality of phospholipids.
