FAQs
Q1.
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.
Q2.
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.
pH Range: Stable in pH 3–8, outperforming regular ascorbic acid in alkaline premixes.
Oxidation Resistance: 50% slower oxidation rate vs. unprotected Vitamin C.
Q3.
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.
- 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.
Q4.
What is the recommended dosage for different animal species?
For Aquatic Feed (Fish, Shrimp, Crab), the recommended dosage is 0.5–1.0 kg per metric ton of feed. For Livestock & Poultry Feed (or Stress Relief), it is 0.2–0.5 kg per metric ton of feed. Dosage should be adjusted based on species requirements or veterinary advice.
Q5.
How should Vitamin C (L-Ascorbic Acid-2-Phosphate) be stored, and what is its shelf life?
It should be stored in a cool, dry, well-ventilated area, protected from light. Opened packages must be resealed immediately and used promptly. The shelf life of this product is 24 months under proper storage conditions.
Q6.
What compliance standard and active ingredient content does this product meet?
