Key Takeaways
| Amino Acid | Shelf Life | Key Storage Concern | Optimal Temperature |
|---|---|---|---|
| L-Lysine | 2-3 Years | Moisture Absorption | 15-30°C |
| DL-Methionine | 3 Years | Oxidation (Air Exposure) | 5-30°C |
| L-Threonine | 2 Years | Temperature Sensitivity | 5-25°C |
Amino acids are important building blocks for animals. They help animals grow strong and healthy. For these animal nutrition supplements to work, they must be stored correctly. If they are not stored well, they can lose their power. This guide will explain how to store three common amino acids: L-Lysine, DL-Methionine, and L-Threonine. Proper storage keeps the product safe and effective. It makes sure the animals get all the benefits from their feed. Keeping amino acids in good condition is a key part of quality animal care.
Storing amino acids correctly protects them from harm. The biggest enemies of amino acids are heat, moisture, and light. When amino acids get too hot or wet, they can spoil. This process is called degradation. One type of degradation is the Maillard reaction, which makes lysine unusable for animals. Another problem is oxidation, which harms methionine. Good storage prevents these issues. It ensures that the China feed additives you buy maintain their quality from the factory to the farm. Simple care in storage protects your investment and the animals' health.
L-Lysine HCl 98.5% is a stable product, but it is very sensitive to moisture. It can pull water from the air, which causes it to clump together. To prevent this, you must keep it dry.
You can check the quality of L-Lysine with your eyes and nose. Fresh L-Lysine is a white powder. If it turns yellow, it might be degrading. A strange smell can also be a sign of a problem. Another key indicator is clumping. If the powder is caked together, it has been exposed to too much moisture. This is especially important information for those who use the benefits of lysine poultry feed, as consistent quality is vital. Always check your product when you receive it and before you use it.
DL-Methionine 99% has a different challenge. Its structure contains sulfur, which makes it sensitive to oxidation. This means it can be damaged by too much exposure to air. The key is to store it in a cool, well-ventilated area away from direct sunlight.
To ensure DL-Methionine stays effective, you should check its quality. The product should be a white crystalline powder. It should have a purity of at least 99.0% and a moisture content of no more than 0.3%. Proper storage will help maintain these levels throughout its shelf life. As an expert, I always advise rotating your stock. Use the oldest bags first to ensure nothing sits for too long, even within its shelf life. This simple step preserves the quality of all your Amino Acids.
L-Threonine is sensitive to both heat and moisture, but it is moderately stable. The main concern is high temperature, which can speed up degradation.
Each amino acid has unique needs. This table shows the main differences at a glance. Understanding these differences is key to managing all essential amino acids for animal nutrition in your inventory.
| Amino Acid | Optimal Temperature | Humidity Range | Shelf Life | Primary Concern |
|---|---|---|---|---|
| L-Lysine | 15-30°C | <60% RH | 2-3 years | Moisture absorption |
| DL-Methionine | 5-30°C | 20-75% RH | 3 years | Oxidation sensitivity |
| L-Threonine | 5-25°C | <60% RH | 2 years | Temperature sensitivity |
Good storage practices apply to all feed additives. Your storage area should be climate-controlled to manage temperature and humidity. Always store bags on pallets, not directly on the floor, to avoid ground moisture. Use a First-In-First-Out (FIFO) system. This means you use the oldest stock first. Regular visual checks for clumps, discoloration, or bad smells can catch problems early. A clean, organized storeroom is the foundation of product quality.
Proper storage is not a cost; it is an investment. Every bag of amino acids that spoils is lost money. By protecting your products, you prevent these losses. Good storage also protects your reputation. Customers trust suppliers who deliver high-quality, effective products every time. For a company like Pangoo, which has over 30 years of experience, maintaining quality through proper storage is essential for customer satisfaction and business success. It shows a commitment to excellence that customers value.
Feed additives must meet strict quality standards. Companies often follow rules like Good Manufacturing Practices (GMP) and hold certifications like ISO9001. These standards require careful documentation. You must keep logs of storage temperatures, humidity levels, and product batch numbers. Having a clear COA (Certificate of Analysis) for each batch provides proof of quality. This paperwork is not just for regulators. It is a tool for ensuring that every product meets the highest safety and performance standards before it reaches the customer.
What happens if amino acids get wet? If amino acids get wet, they can clump together, grow mold, and lose their nutritional value. L-Lysine is especially prone to this. Wet product should not be used.
Can I use amino acids past their shelf life? It is not recommended. After the expiration date, the amino acid may have lost its potency and will not provide the intended benefits to the animals.
What is the best temperature to store amino acids? Most amino acids should be stored in a cool, dry place. A temperature range between 15-25°C (59-77°F) is generally safe for L-Lysine, DL-Methionine, and L-Threonine.
Why does DL-Methionine need special care? DL-Methionine contains sulfur, which makes it react with oxygen in the air. This process, called oxidation, can damage the product. It must be stored in sealed containers to limit air exposure.
