Health notes

Fried onion is not a food additive and does not have an E-number. The health implications are primarily related to the nutritional content of the onion itself and the oil used for frying. Onions are a source of fibre and various phytonutrients. Frying can increase the fat and calorie content of the onions. The NHS Eatwell Guide advises a balanced diet with plenty of fruit and vegetables.

Allergen info

Fried onion itself is not one of the 14 major allergens. However, if fried in oil containing allergens, or if cross-contamination occurs during processing, it may contain traces of allergens. Always check the ingredients list for specific allergen information.
