Ingredients, colour-coded
What needs attention
- DoubtfulWhey
Whey comes from cheese making, so the rennet question applies: pig rennet is prohibited, rennet from a correctly slaughtered animal is permitted, and rennet from an animal that was not slaughtered is disputed. The pack rarely says which rennet was used. Doubtful unless it came from cheese made with microbial rennet, or the product has a halal logo.
- DoubtfulEmulsifier (source not stated)
The word "emulsifier" does not say which one is used. Several emulsifiers, including E471, are made from glycerol and fatty acids that can come from plants or animal fat, and the pack rarely says which. Doubtful unless the pack names a plant source, or shows a vegetarian, vegan or halal label.
- DoubtfulFlavourings
The word "flavouring" does not say what a flavour is made from or dissolved in. Most are plant-based or synthetic, but some are carried in alcohol or glycerol of unstated source, and a few contain animal ingredients. Doubtful unless the pack says plant-based or alcohol-free, or shows a halal logo.
- DoubtfulCheese
Depends on the rennet. Many UK supermarket cheddars use microbial rennet and are labelled vegetarian; Parmesan and Grana Padano always use animal rennet.
