What is The Solubility of Ascorbic Acid (vitamin C) in Pet Food Formulations?
1. Water Solubility: ~33g/100mL at 25°C (highly soluble)
2. Fat Solubility: Poor (not soluble in oils or fats)
3. Best Form for Water-Based Pet Supplements: Pure Ascorbic Acid or Sodium Ascorbate
4. Best Form for Fat-Based Pet Supplements: Ascorbyl Palmitate (a fat-soluble derivative)
How is The Ascorbic Acid Stability in Pet Food Processing?
Ascorbic Acid is sensitive to heat, light, and oxygen, affecting its stability in pet formulations:
1. Dry Kibble & Treats: Degrades significantly during high-temperature extrusion. Encapsulated or stabilized forms (Calcium Ascorbate, Sodium Ascorbate) are better choices.
2. Canned & Wet Pet Food: Moderate stability but can degrade over time due to heat and storage conditions.
3. Liquid Supplements: Requires pH control and antioxidant protection (e.g., combined with Vitamin E) to prevent oxidation.
4. Freeze-Dried & Raw Diets: Best preserved when added in post-processing or as a coated ingredient.
Formulation Tip for Pet Food Suppliers
- Use coated Ascorbic Acid or encapsulated Vitamin C to improve stability in kibble or wet food.
- For liquid supplements, combine with stabilizers to prolong shelf life.
- Use Calcium Ascorbate or Sodium Ascorbate in pet food for better stability compared to pure Ascorbic Acid.
