FAQs
1. 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.
2.How stable is this product during feed processing and storage?
Heat Stability: Maintains 95% activity after pelleting at 90°C for 2 minutes.
pH Range: Stable in pH 3–8, outperforming regular ascorbic acid in alkaline premixes.
Oxidation Resistance: 50% slower oxidation rate vs. unprotected Vitamin C.
3.Is it compatible with choline chloride, trace minerals, or antibiotics?
Compatible:
Choline chloride (<50%) – no hygroscopic clumping due to phosphate coating.
Zinc oxide, Copper proteinate – no redox reaction in neutral pH.
Incompatible:
High-dose ferrous sulfate (>300 ppm) – catalyzes phosphate hydrolysis.
Alkaline binders (pH >8.5) – gradual dephosphorylation over 14 days.
