What Is Halal Analysis?
Halal compliance analysis is the laboratory investigation of whether the product contains ingredients that violate halal requirements. There are two main analyses: detection of porcine DNA by real-time PCR and determination of ethanol content by gas chromatography. The source of components such as gelatin, emulsifier and enzyme can also be investigated by species determination.
Purpose of Halal Analysis
The aim is to provide laboratory evidence to the halal certification process. Analysis is not a substitute for documentation; Halal compliance is a system issue that includes slaughter method, production line separation and supply chain control.
Which Products Is Halal Analysis Applied To?
- Meat and meat products
- Foods and supplements containing gelatin
- Dairy products and cheese (enzyme source)
- Flavor and additives
- Cosmetics and pharmaceutical products
In Which Sectors Is Halal Analysis Used?
Standards Related to Halal Analysis

- OIC/SMIIC 2 (requirements for halal certification bodies)

- TS EN ISO 21571 (nucleic acid extraction)
Halal Analysis Conditions
- Species determination
- Real-time PCR for pig specific target region
- Etanol
- By gas chromatography; Levels resulting from natural fermentation are evaluated separately
- Processing effect
- DNA may be fragmented in gelatin and refined products
Equipment for Halal Analysis
- Real-time PCR system
- DNA extraction setups
- GC-FID (etanol tayini)
- LC-MS/MS (peptide-based verification)
Sample Requirements for Halal Analysis
- Temsil edici numune
- Component list and supplier information must be provided
- Critical components such as gelatin and enzyme can be sampled separately
- Production line information should be reported
Duration of Halal Analysis
DNA extraction and PCR take several working days. Ethanol determination is shorter. For processed ingredients such as gelatin, the time is extended when additional verification is required.
Halal Analysis Procedure
- 1Product components and critical points are determined.
- 2The sample is homogenized and DNA is extracted.
- 3DNA quality and reference gene control is performed.
- 4Pig-specific real-time PCR is applied.
- 5Gas chromatography measurement is performed for ethanol.
- 6The results are evaluated within the framework of halal conditions.
Halal Analysis Acceptance Criteria
The acceptance criteria are the applied halal standard and the conditions of the certification body; OIC/SMIIC 1 defines this framework. Detection of pork-derived ingredients is non-compliance. The acceptable level for ethanol is evaluated according to the standard and its source (intentional addition or natural fermentation).
Evaluation of Results
A negative PCR result is limited to the detection limit of the method and may not yield results in components with fragmented DNA, such as refined gelatin. For these products, conformity is demonstrated through supply chain documentation and production auditing. Laboratory results do not replace the halal certificate.

Accreditation
EUROLAB holds internationally recognised accreditation obtained from accreditation bodies party to the IAF and ILAC multilateral recognition arrangements, under ISO/IEC 17025 for laboratory testing, ISO/IEC 17020 for inspection and surveillance, and ISO/IEC 17021-1 and ISO/IEC 17065 for system and product certification. This chain ensures the reports and certificates issued are accepted worldwide.
Whether this test can be offered within accredited scope depends on your product and the standard applied; since accreditation is method-based, the scope is confirmed in writing at the quotation stage.

Food Testing — What Does This Testing Field Cover?
The section below describes the field that the Halal Analysis test belongs to; the conditions and acceptance criteria of this particular test are given in the sections above. The scope specific to your product is confirmed in writing at the quotation stage.
Food testing shows that a product is safe for consumption and contains what its label states. The family works along three axes: microbiological safety, chemical safety and nutritional composition. All three require different laboratory infrastructure, a different body of methods and a different turnaround time.
The most distinctive feature of the field is TIME PRESSURE. A steel specimen can wait on a shelf; a raw milk or fresh meat sample cannot. The time the sample was taken, the transport temperature and how long it takes to reach the laboratory directly determine the validity of the result. In food microbiology the cold chain record is therefore an inseparable part of the test report.
On the microbiological side there are two different questions and they must not be confused. DETECTION of a pathogen is a qualitative question: is Salmonella present in the sample or not? ENUMERATION of indicator organisms is a quantitative question and an indicator of production hygiene. The absence of a pathogen in a product does not show that hygiene is good; if the total mesophilic aerobic count is high, there is a problem in the process.
On the chemical side, pesticide residues, mycotoxins, heavy metals, additives, veterinary drug residues and process contaminants (acrylamide, furan, PAH) are measured. Multi-residue methods in this area (QuEChERS-based LC-MS/MS and GC-MS/MS) can screen hundreds of active substances in a single analysis; limits are defined separately for each product–substance pair.
On the composition side, protein, fat, moisture, ash, fibre, sugar profile, fatty acid composition, vitamin and mineral content are determined. These values are the basis of the nutrition declaration on the label and the tolerance ranges are defined in legislation — the difference between the declared value and the measured value must stay within that tolerance.
There is NO CE marking on food, and this shapes how the field works. Conformity is demonstrated through operating a HACCP-based food safety system, complying with labelling rules and not exceeding contaminant, residue and microbiological limits. A test result produces evidence not for a certificate but for a functioning system.
Allergen management carries particular weight. The presence of an undeclared allergen in a product is one of the most frequent causes of food recalls. Analysis here runs together with cleaning validation: it is shown that the line has been cleaned adequately after a production run containing an allergen and that the risk of cross-contamination is under control.
Voluntary schemes have become effectively mandatory in this field. Retail chains require their suppliers to hold a certificate under a GFSI-recognised scheme (BRCGS, IFS, FSSC 22000); without it, getting onto the shelf is practically impossible.

Commonly confused in this field
- Sampling is half the result. A sample transported at the wrong temperature or delayed gives an invalid result even if it is analysed correctly in the laboratory.
- The absence of a pathogen does not show that hygiene is good; indicator counts give separate information and the two are read together.
- A result from a sample taken from a lot can be generalised to the whole lot only if the sampling plan was set up statistically.
- Limits are defined in separate regulations by product group and are updated regularly; a conformity decision based on an outdated limit table may be wrong.
- For exports, the limits of the destination country may differ from EU limits; the same product may be compliant in one market and non-compliant in another.
Which decisions these results support
- Verification of the HACCP plan and process monitoring
- The basis for the nutrition declaration and allergen information on the label
- Health certificates before export and compliance with destination market limits
- Supplier and lot-based acceptance control

Frequently Asked Questions About Halal Analysis
Does the analysis replace the halal certificate?
It doesn't pass. Halal compliance; It is a system that covers raw material source, cutting method, line separation, cleaning and traceability. Laboratory analysis is one of the verification tools of this system.
Can the source of gelatin be determined by analysis?
Partially. PCR may not yield results because the DNA is largely fragmented during the production process; Peptide-based LC-MS/MS approaches provide discrimination in some cases. The definitive basis is supply chain documentation.
