Sardine fillets

Sardines are small, oily fish belonging to the herring family. They are typically caught in the wild from oceans around the world and are often preserved by canning, usually in oil, tomato sauce, or brine. This process helps to extend their shelf life and make them convenient for consumption.

Sardines are primarily consumed as a food product themselves, valued for their rich flavour and nutritional content. Manufacturers may add them to prepared meals, salads, or pasta dishes to provide a source of protein and omega-3 fatty acids. They are not typically used as a functional ingredient like a preservative or emulsifier.

Sardines are a whole food, not a food additive, and are widely available in the UK. They are a good source of protein, vitamin D, and omega-3 fatty acids, which the NHS notes may contribute to heart health. As a fish, they can contain naturally occurring purines, which may be a consideration for individuals managing conditions like gout. There are no specific regulatory evaluations for sardines as an additive, as they are a foodstuff.
