Gelatin, E-additives, enzymes and flavorings: the principles of processed-food fiqh and the contemporary academies' decision rules.

Updated on 31 August 2026 at 3:55 AM

Processed foods raise a new question: what to do with ingredients derived from prohibited animals (gelatin, enzymes, coagulants) or of uncertain origin (flavourings, E-number additives)? The named resolutions of the International Islamic Fiqh Academy (OIC) answer with established principles.

The three principles

  • The default rule is lawfulness: "eat of what Allah has provided you, lawful and good" (sura al-Ma'ida 88); prohibition is established by proof, not by generalised suspicion: "the lawful is clear and the unlawful is clear; between them is what raises doubt" (al-Bukhari 2051);
  • complete transformation (istihala): the International Islamic Fiqh Academy, resolution no. 23 (3/3), 3rd session (Amman, 1986): substances drawn from non-slaughtered animals change status when the transformation is complete; the example quoted by the resolution is precisely the hide turned into gelatin;
  • certainty prevails over doubt: the unknown origin of an additive is presumed lawful until contrary information; an established unlawful origin (without transformation) is avoided.

Practical cases

  • Gelatin: declared porcine gelatin: avoided out of caution by many scholars, accepted by others after complete transformation; of undetermined origin: presumed lawful according to the presumption above; from ritual slaughter: lawful; resolution no. 210 of the Academy (21st session), on transformation and additives in food and medicine, recommends extracting gelatin from the skins and bones of ritually slaughtered animals;
  • rennet (cheese enzyme): lawful from an animal slaughtered ritually; of undetermined origin: presumed lawful by the majority, Malik being stricter;
  • E-number additives: analysed by code (E120 cochineal, E441 gelatin); mineral chemical codes are lawful;
  • flavourings carrying traces of alcohol: non-intoxicating traces not intended to intoxicate: accepted by the majority of contemporary jurists (see the vinegar page).

Practical note

The serene method: read the ingredient list, identify the risky codes, check with a serious certification body, and avoid generalising doubt: "whoever avoids doubt purifies his religion and his honour" (al-Bukhari 2051). Personal caution is recommended; accusing the products of others is not.
