To ensure compliance, products must carry a valid Halal certificate issued by a recognized body such as JAKIM (Malaysia), MUI (Indonesia), or GAC (Gulf Accreditation Center). The certification must verify that all ingredients, including emulsifiers (E471), enzymes, and flavorings, are derived from permissible plant or synthetic sources rather than non-halal animal fats. Additionally, the production facility must be strictly segregated from non-halal processing lines to prevent cross-contamination.
