Product Details
Frequently Asked Questions
What are the advantages of L-Ascorbic Acid-2-Phosphate over regular Vitamin C in feed?
This stabilized Vitamin C derivative provides enhanced heat and pH stability, retaining over 90% activity under pelleting conditions (85°C for 3 minutes). It is ideal for species requiring long-term antioxidant support, such as poultry under heat stress and aquaculture in high-oxygen environments.
How stable is this product during feed processing and storage?
It exhibits excellent heat stability, maintaining 95% activity after pelleting at 90°C for 2 minutes. It is stable in a broad pH range of 3–8, outperforming regular ascorbic acid in alkaline premixes, and features a 50% slower oxidation rate compared to unprotected Vitamin C.
Is it compatible with choline chloride, trace minerals, or antibiotics?
Yes, it is compatible with choline chloride (<50%) without causing hygroscopic clumping due to its protective phosphate coating. It is also compatible with zinc oxide and copper proteinate in neutral pH. However, avoid high-dose ferrous sulfate (>300 ppm) and alkaline binders (pH >8.5) as they can cause hydrolysis and dephosphorylation.
What is the recommended dosage for different animal feeds?
For aquatic feed (fish, shrimp, crab), the recommended dosage is 0.5–1.0 kg per metric ton. For livestock and poultry feed (especially for stress relief), the recommended dosage is 0.2–0.5 kg per metric ton. Dosages can be adjusted according to species needs or veterinary guidance.
What are the storage requirements and shelf life of this product?
It should be stored in a cool, dry, and well-ventilated area, protected from direct light. Once packages are opened, they should be resealed immediately and used promptly. Under these conditions, the product has a shelf life of 24 months.
How does the product perform in high-temperature feed processing?
This product is designed for high thermal stability, resisting degradation under extrusion processing temperatures up to 150°C and maintaining 95% activity after pelleting at 90°C for 2 minutes.
