Is Natamycin Halal? E235 (Pimaricin) Explained
In briefNatamycin (E235 / Pimaricin) is a natural antifungal preservative produced by bacterial fermentation — no animal-derived ingredients involved. It is classified as halal by JAKIM, MUI, BPJPH, and ESMA. The only halal concern is the food product it is used in, not the natamycin itself.

Natamycin (E235 / Pimaricin) is halal. It is a natural antifungal preservative produced by the bacterium Streptomyces natalensis through fermentation of a plant-based substrate. No animal-derived ingredients are involved in its production. All major halal certification bodies, including JAKIM, MUI, and ESMA, permit natamycin in certified halal products. The only relevant halal consideration is not the natamycin itself but the food product it is applied to — particularly when used on sausage casings, which may be porcine-derived.
What Is Natamycin (E235)?
Natamycin — also known by its trade name Pimaricin — is a naturally occurring polyene macrolide antifungal compound. It was first isolated in 1955 from Streptomyces natalensis, a soil bacterium found in the Natal region of South Africa.
As a food additive (E235), natamycin is used exclusively as an antifungal surface preservative. It prevents mould and yeast growth on the surface of food products, extending shelf life without affecting the internal composition of the food or its taste.
Principal applications include:
- Cheese: applied as a surface spray, dip, or coating to hard and semi-hard cheeses (Gouda, Edam, Cheddar, Parmesan) to prevent surface mould during ripening and storage
- Fermented meat products: applied to the surface of dry-cured sausages and salamis to prevent surface mould during the curing process
- Yogurt: added at low concentrations to prevent yeast overgrowth during refrigerated storage
- Baked goods: used in some markets on bread crusts and other baked products
- Dried fruits and spices: used as a surface preservative in some applications
Natamycin is not metabolically active at the concentrations used in food — it acts on the surface membrane of fungal cells and is not significantly absorbed through the human gut. This is relevant because it reinforces its status as a surface agent rather than a systemic food ingredient.
How Is Natamycin Produced?
Commercial natamycin is produced entirely by microbial fermentation:
- Fermentation substrate: Streptomyces natalensis or related strains are grown in a fermentation medium containing plant-derived carbon sources (glucose, starch) and nitrogen sources (typically from plant-based peptones or inorganic ammonium salts).
- Biosynthesis: The bacteria produce natamycin as a secondary metabolite during fermentation. The compound is secreted into the fermentation broth.
- Recovery: Natamycin is extracted from the broth by filtration and precipitation, then purified by recrystallisation.
- Formulation: The purified natamycin is formulated as a suspension or powder for food applications. Common carriers include water, lactose, or glucose — all halal-compliant.
The production process is analogous to that of other fermentation-derived food preservatives. No animal-derived ingredients are required at any stage of standard industrial production.
Halal Status of Natamycin Itself
Natamycin's halal status is unambiguous:
- Origin: microbial fermentation (non-animal)
- Fermentation substrates: plant-based carbon and nitrogen sources
- No alcohol processing: recovery uses aqueous extraction and precipitation, not solvent extraction with ethanol
- JAKIM position: permitted in halal-certified products
- MUI/BPJPH position: permitted; required documentation of source and process
- ESMA (UAE) position: compliant with Gulf halal standard when produced from non-animal substrates
There is no scholarly controversy around natamycin itself. It is consistently classified as halal by all major certification bodies.
The Sausage Casing Context: Why Natamycin Sometimes Raises Questions
The most common source of halal-related questions about natamycin is its use on fermented meat products — specifically dry-cured sausages and salamis. Here, the concern is not the natamycin but the casing.
Traditional dry-cured sausages (salami, pepperoni, chorizo) are often encased in natural animal casings, which may be derived from:
- Porcine (pig) intestines — haram
- Bovine (cattle) intestines — halal if from halal-slaughtered animal
- Sheep intestines — halal if from halal-slaughtered animal
- Collagen casings (from bovine hides) — halal if source-verified
- Cellulose or plastic casings — halal
Natamycin is applied to the surface of the casing to prevent mould during the curing period. Consuming a sausage in a porcine casing treated with natamycin presents two separate halal concerns: the porcine casing (haram) and the natamycin (halal). It is the casing, not the natamycin, that determines the product's halal status.
This distinction is important for consumers and importers: if a product label lists E235 natamycin, the preservative itself is not a red flag. The question to investigate is: what type of casing does this sausage use?
What Do the Major Halal Certifiers Say?
JAKIM (Malaysia)
JAKIM permits natamycin (E235) in halal-certified food products. Malaysian halal-certified cheese and dairy products routinely use natamycin as a surface preservative. JAKIM's focus when auditing natamycin use is on confirming the carrier medium (lactose, glucose) is from a halal-compliant source.
LPPOM MUI / BPJPH (Indonesia)
Indonesia permits natamycin in halal-certified products. Domestic food standards (SNI) allow natamycin in yogurt (up to 10 mg/kg), hard cheese, and processed cheese. MUI-certified dairy products commonly use E235.
ESMA (UAE)
The Gulf halal standard (GSO 2055-1) and ESMA's implementation permit microbially produced preservatives including natamycin. Cheese exported to the UAE carrying ESMA halal certification may use E235.
HFA / HMC (UK)
UK halal certification bodies have not raised objections to natamycin in dairy products. The focus of UK halal audits for cheese is on the rennet source (animal vs. microbial) and the natamycin carrier medium, not the natamycin compound itself.
Natamycin in Cheese: Key Halal Checkpoints
For Muslim consumers buying cheese that contains natamycin, the real halal checklist is:
- Is the rennet used halal? Rennet (the coagulant) is a more significant halal concern than natamycin — animal rennet from non-halal-slaughtered animals renders the cheese non-halal regardless of the preservative. Look for microbial rennet, vegetable rennet, or halal-certified animal rennet.
- Does the product carry halal certification? A halal certificate from a recognised body covers the entire production process including the natamycin application method and carrier.
- Is the product from a country with strong halal dairy infrastructure? Malaysia, Indonesia, and Gulf-exported cheese often carries JAKIM, MUI, or ESMA certification and is a reliable choice.
Approved Usage Levels by Regulatory Standard
For reference, approved maximum levels of natamycin (E235) in food include:
- EU (Regulation EC 1333/2008): Hard, semi-hard and semi-soft cheese — 1 mg/dm² surface; not present at depth of 5 mm. Dried cured sausage — 1 mg/dm² surface.
- Codex Alimentarius: 20 mg/kg in processed cheese; surface treatment in hard cheese.
- Indonesian SNI: Yogurt 10 mg/kg; cheese as per Codex.
These trace quantities reinforce that natamycin is a surface agent present in minimal amounts in consumed food.
Frequently Asked Questions
Is E235 halal?
Yes. Natamycin (E235) is produced by bacterial fermentation from plant-based substrates and is classified as halal by all major certification bodies including JAKIM, MUI, BPJPH, and ESMA.
Does natamycin come from animals?
No. Natamycin is produced by Streptomyces natalensis, a soil bacterium. The fermentation process uses plant-derived substrates. There is no animal-derived input in standard industrial production.
Why is natamycin used on sausage casings?
Natamycin is applied to the outer surface of dry-cured sausages to prevent unwanted mould growth during the extended curing period. It inhibits specific surface mould while not interfering with the desired maturation of the sausage. The halal concern with such sausages is the casing material (possibly porcine), not the natamycin.
Is natamycin the same as pimaricin?
Yes. Pimaricin is the original pharmaceutical name for the same compound. In food contexts, the terms natamycin and E235 are standard. In pharmaceutical and ophthalmological applications, it is often referred to as pimaricin.
Is natamycin safe to consume?
Yes. JECFA (Joint FAO/WHO Expert Committee on Food Additives) has established an Acceptable Daily Intake (ADI) for natamycin, and regulatory bodies in the EU, USA, and across Asia have approved its use in specified food applications at defined maximum levels. Its low gastrointestinal absorption is well-documented.
