Antioxidants (Natural or Synthetic)
Antioxidants (natural or synthetic) are specialized additives for cat and dog food designed to protect fats, oils and other sensitive nutrients from oxidation. Their use prevents rancidity, loss of nutritional value and deterioration of color and aroma in complete diets, treats and complementary pet products. In formulations for cats and dogs, antioxidants support feed stability throughout storage and distribution, preserving palatability and consistent finished product quality.
Source
Antioxidants used in cat and dog nutrition may be:
- natural, based on extracts rich in tocopherols, polyphenols and other phytonutrients
- synthetic, such as BHA, BHT and ethoxyquin, developed to deliver strong and reliable antioxidative effects at low inclusion rates
Variations
- Natural antioxidants (mixed tocopherols, rosemary extract and other plant extracts)
- Synthetic antioxidants with strong activity and extended stability
- Combined systems (natural + synthetic) balancing “clean label” demands with high protection of fats
- Dedicated blends for fat premixes, dry food, wet food and treats
Applications In The Industry
Dogs
In dog food, antioxidants are applied in dry kibbles, canned products, semi‑moist diets and treats, especially in formulas with a high level of animal fats and oils. During manufacturing they are added to the oil phase, into premixes or directly into the finished mix to extend shelf life, maintain palatability and reduce rancidity risk under various storage and climate conditions. Natural antioxidants are often chosen for premium and grain‑free concepts, while synthetic options provide robust protection in cost‑effective product lines.
Cats
In cat food, antioxidants play a key role in protecting high fat content and protein components that drive aroma and taste, particularly in dry food, snacks and complementary diets. They are used in feline formulas rich in animal fats and fish oils, where oxidation can rapidly impair quality. Properly selected and dosed antioxidant systems help secure stable aroma, flavor and texture throughout the declared shelf life, which is critical for cats that are highly sensitive to changes in palatability.
Benefits Of Use
- Protection of fats, oils and sensitive nutrients from oxidation and rancidity
- Extended shelf life and preserved sensory quality of cat and dog food
- Maintenance of palatability and acceptance during storage
- Flexible use in dry and wet food, premixes and pet treats
