Why this verdict

E1101 is protease, a class of enzymes that break down protein, used in baking, brewing, meat tenderising, and dairy processing. It can be derived from microbial fermentation, plants (such as papain from papaya), or animal sources (including pig pancreas). No major halal authority in the source corpus has published a per-additive position on E1101. Without source disclosure the additive defaults to doubtful unless the product carries halal certification confirming a microbial or plant-derived source.
