Is Enzymes and rennet halal?
Enzymes make cheese curdle, bread rise and juice clear. They can be grown in a fermentation tank or cut from a calf's stomach — and the label just says 'enzymes'.
Microbial, fungal and plant enzymes are halal. Animal enzymes inherit the source animal: porcine pepsin and lipase are haram; calf rennet depends on slaughter. Cheese is the main battleground.

The detail
The American Halal Foundation's ingredient guide is specific: pepsin comes from pig stomachs, lipase can come from pork, and cheese must be made with microbial rennet or halal-certified animal rennet. IFANCA lists enzymes among doubtful ingredients in cheese and bagels. The resolution is usually printed if you know the words: 'microbial rennet', 'vegetable rennet' or 'enzymes (microbial)' are halal routes; bare 'rennet' or 'enzymes' in an uncertified cheese is the doubtful case. Many major US cheese brands use microbial chymosin — but 'many' is not a label claim.
