Swizzels Pig’s Mugs are fun-shaped, fruit-flavoured gums containing glucose syrup, sugar, gelatine, apple pulp (which contains the preservative sulphur dioxide), modified starch, acidity regulators (citric acid and trisodium citrate), flavourings, glazing agents (vegetable oil, palm, and carnauba wax), and a colour (anthocyanin). For allergens, this product contains sulphur dioxide/sulphites and gelatine, the latter making it unsuitable for vegetarians and vegans. The manufacturer, Swizzels, and some retailers mention that the product is made in a facility that also handles other allergens, including milk, soya, gluten, nuts, and peanuts, so cross-contamination is a possibility.
