Swizzels Squashies Rhubarb & Custard are made with glucose syrup, sugar, gelatine, modified starch, acidity regulators (citric acid and trisodium citrate), apple pulp, flavourings, and a glazing agent (carnaubawax). Natural colours like anthocyanin, curcumin, and lutein are also included to give them their distinct colour. The product’s main allergen is gelatine, which is sourced from animal products and makes the sweets unsuitable for vegetarians and vegans. Custard is mentioned in the flavour name, but the sweetness comes from flavourings and sugars rather than actual dairy. The manufacturers and retailers note that some Squashies contain apple pulp, which may be preserved with sulphur dioxide, and it is manufactured in facilities that also handle other allergens, including milk, soya, nuts, and peanuts. Therefore, individuals with severe allergies to these substances should be aware of the risk of cross-contamination.
