The additive premix is highly hygroscopic and prone to clumping, so it must be stored in a sealed, moisture-proof container. Vacuum packaging is the most effective method for preserving its quality. Additionally, the product should be kept in a dry, cool, and dark place. The ideal storage conditions are typically a temperature between 15°C and 20°C, with a relative humidity of 55% to 68%. For large-scale farms, especially during summer, it's recommended to use forced ventilation systems to maintain product integrity throughout its shelf life.
Once the package is opened, the additive premix should be used as soon as possible. Any remaining portion must be resealed and stored properly. The various components within the premix can interact with each other, particularly affecting the stability of vitamins. Therefore, it’s important to use the product promptly rather than storing it for long periods.
For high-concentration single-vitamin premixes, fiberboard boxes (tubes), plastic-lined bags (such as 11315, -260.00, -2.25%), or three-layer kraft paper packaging is commonly used. For vitamin-containing premixes, a four-layer sealed package made of plastic film is recommended to enhance preservation. This type of packaging helps protect the product from moisture, light, and air exposure, ensuring longer stability.
Vitamin premixes that do not contain choline chloride or vitamin C usually have a shelf life of less than six months. However, those containing complex vitamin blends should be used within one month for optimal effectiveness. It's crucial to check the expiration date and follow the manufacturer's guidelines to ensure safety and efficacy. Proper handling and storage play a key role in maintaining the potency of these sensitive products.
