This article examines the role of antioxidants in food production and their contribution to quality and shelf life.
Limiting oxidative deterioration
Antioxidants help slow oxidation reactions that can damage food components. Depending on their mechanism and application, they support the retention of flavour, colour and quality during storage.
Product stability: protecting flavour and colour
Antioxidants can help protect fats against rancidity and limit unwanted changes in taste and colour. Their effectiveness depends on the formulation, processing and exposure to oxygen, heat and light.
Supporting shelf life
By slowing oxidative deterioration, antioxidants can help extend the period during which a food retains acceptable quality. This can reduce losses, provided that storage and packaging conditions are appropriate.
Technological function and nutritional claims
The use of an antioxidant to preserve a food should be distinguished from a claim about its effect in the human body. Any nutrition or health claim for a finished product requires its own evidence and compliance with applicable rules.
Antioxidants: maintaining food quality
Antioxidants are important tools for managing oxidative changes in food. Selecting the right ingredient and dose helps maintain flavour, colour and stability. Their performance should be validated in the finished product throughout its intended shelf life.
