enzyme · ingredient
Enzyme; source not declared on a bare label. The dominant commercial form is fungal fermentation (Aspergillus niger, non-animal-source), but a bare 'glucose oxidase' name does not establish a permissible source. Tightened to MUSHBOOH+source_required to match the live dictionary/e-code verdict (E1102 = MUSHBOOH) and the source-ambiguity convention — verify with the manufacturer. NOT scholar-ratified; cross-check vs JAKIM MS 1500:2019 (general enzyme-source provisions).
