Arnott's Clix & Tasty Cheese 31g is mushbooh (doubtful): Cheese rennet unspecified — the manufacturer's response confirmed the doubt.
What's in doubt
Manufacturer reply
“Arnott's are currently not Halal certified. … There are animal-based ingredients that may or may not be acceptable such as eggs, gelatine, milk powder and potentially some colours or flavours. These ingredients are used throughout our bakeries.”
Cheese rennet unspecified
This product declares cheese or dairy enzymes without naming the rennet source. Rennet can be animal- or microbially-derived, and Arnott's does not confirm ingredient sources.
