The species-specific sequence variations that underpin DNA barcoding also mean that the length of the DNA-fragment bookended by universal primers will differ from species to species, particularly if it is genomic DNA that has been targeted.

Fragments of different lengths can then be separated by chromatography, giving a chromatogram where the retention time is indicative of the fragment length and hence the species and the peak area is indicative of the fragment concentration and hence the copy numbers in the sample.

This gives an approximate quantification of each species in the mix. Specific primers are most commonly used for meat species identification. Each primer pair is selective for one species. Combinations of different primers can be used within the same PCR assay; e.

multiple different primer pairs for beef, horse, pork, goat, chicken, turkey, and donkey all within the same mix. If a fluorescent dye is incorporated into the DNA during PCR then the progress of the amplification can be measured in real time.

The more amplified DNA produced, the stronger the fluorescent signal. Monitoring the fluorescence signal vs cycle numbers gives a characteristic flat baseline, followed by steep increase, followed by plateau. The steep increase corresponds to the point where DNA copy numbers rise exponentially from too-few-to-detect to overly-saturated.

The number of cycles before this steep curve occurs is indicative of the number of DNA copies in the original mix. It can be calibrated in a semi-quantitative manner. Alternately, the curve produced by a given species can be retrospectively calibrated as a percentage of the total primer-targeted DNA in a multi-species assay.

If the target DNA has not been fully studied or characterised then it is still possible to perform PCR using a collection of generic short primers in the hope that they will latch somewhere onto the DNA and produce PCR fragments.

The pattern of random fragments produced by a given set of primers is then unique to the species, and so can be compared to an in-house reference. Rather than amplification by PCR, DNA can also be selectively detected by the use of hybridization probes.

These are long strands of bases that have been engineered to form complementary strands with specific regions of target DNA in the sample, binding on like a strip of velcro.

The probes are labelled to enable easy detection, for example with an antigen, a radiolabel, or a fluorescent tag. One common way of using the technique is to design a fluorescent tag that is quenched when the probe binds with its target. The mix is then slowly heated, and at a certain temperature the bound strands will separate and the probe fluoresce again.

when the sample contains the target DNA. Hybridisation probes are particularly suited for point-of-use applications, as the equipment is small and portable and the procedure is faster than PCR. DNA tests are an easily transferrable technology with a wide scope of application.

Because assays can be designed to be incredibly selective there can be good confidence in identification. Although the design of primers takes a great deal of expertise, once they have been engineered they are extremely cheap to mass produce.

Real-time PCR tests are cheap and high-throughput once set up. Sequencing equipment has a high capital cost, but tests are now sufficiently high-throughput that the unit cost is affordable as a routine assay.

The amount of DNA, particularly mitochondrial DNA, extracted from any sample is inherently variable. Different cuts of meat have different amounts of DNA. Fish is even worst — the amount of DNA that can be extracted from fish is so variable as to make quantitation meaningless.

Real-time PCR can be overly sensitive. Not all food sample types have intact DNA that can be extracted. Highly processed meat products, stocks, soups and gelatins have very low amounts of viable DNA.

Laboratories may need to take a try-it-and-see approach in these cases. DNA barcoding can be applied to mixes of species, as even mixed sequences will give a database match.

Public DNA databases are only populated by certified competent laboratories, but there are still occasional errors. This is as likely to relate to inconsistent taxonomy as to errors in the sequences themselves. Some of the reference sequences were generated from specimens of animals or plants collected in the s and put into long-term storage.

Verifying these can mean going back to original taxonomical drawings, which may have been misclassified. Energy is applied to a nucleus for example, in proton-NMR, to the hydrogen nuclei within organic molecules by spinning it within a magnetic field.

As the nucleus loses this energy it re-emits it at a fixed frequency. This frequency is shifted by nearby electrons in the molecule, so a molecule will emit at a number of different frequencies, each characteristic of the neighbourhood of each different excited nucleus. This overall pattern, called a spectrum, is characteristic of the molecule.

Proton-NMR, which is the NMR mode with most food authenticity applications, is suited for identifying molecules with polar hydrogen-containing groups — particularly fats, alcohol and sugars. The higher the resolution stronger and higher frequency of magnetic field , the better the granularity in the spectrum, the more expensive the equipment and the more care needed in its environment and siting.

Low-resolution instruments can be sited at point of use, but high-resolution instruments need well controlled laboratory environments. Sugars are first extracted and fermented to alcohols as alcohols are most amenable to proton-NMR this gives a stronger signal.

This approach has been used successfully since the s for fruit juice identification and has recently been applied to other sugar-rich foods such as honey. High resolution SNIF-NMR is standardised and widely accepted for fruit juice authenticity, with a good robust reference database that has been built in collaboration with the juice industry.

Low resolution NMR is ideal for on-line use in factories, giving results within seconds with little ongoing cost after the initial capital investment. It is well-accepted technology, having been used routinely for many years for measuring the approximate total fat percentage in meat raw materials or product, and so extending scope to applications such as distinguishing the species of frozen white blockfish by its total fat NMR spectrum is just an incremental change for some factories.

Much of the SNIF-NMR technology and databases are proprietary commercial property of Eurofins and, with the exception of fruit juice, there have been industry concerns that reference databases and interpretations are not open to scrutiny or challenge. High resolution NMR requires an extremely well-controlled environment, making it unsuitable for on-site use.

The equipment is also expensive. Spectroscopy exploits the fact that distinctive parts of a molecule will absorb energy at fixed wavelengths and then re-emit energy at discrete frequencies. These frequencies are shifted by neighbouring electrons in nearby parts of the molecule. In this respect, spectroscopy is similar to NMR.

The energy is provided by shining light upon the molecule. Different light frequencies are absorbed by different types of molecular structure.

The most usual light frequencies used for food authenticity testing applications are Infra Red IR, approx. IR, for example, is absorbed and re-emitted by carbon-carbon double bonds. Molecules containing such bonds, for example unsaturated fats, give particularly characteristic IR absorbance spectra.

This is the most common use of infra-red. Spectroscopy is suited to point of use and on-line applications; equipment can be small, portable, and give instantaneous results. NIR, particularly, is suitable for miniaturisation into handheld scanners and even smartphone applications. NIR light also passes through glass and thin plastic, meaning that products can be examined through packaging.

Compared to mass spectrometry and NMR, the equipment is cheap. Spectroscopy is good for checking the overall identity of a food or ingredient but unsuited to detecting low level contaminants or adulterants. Each new application needs a specific local reference database of authentic product; for example, NIR checking of milk authenticity needs a different reference database for each local dairy collection centre.

There are a host of different analytical techniques, only some of which have been covered in this Information Statement. Each technique has its own strengths, applications, and limitations. It is important to understand these in order to interpret results.

It is common to use a panel of different analytical techniques to try and detect a particular food fraud concern. Used generically to describe test methods that identify based on protein sequences within nucleic acids.

Food is considered authentic or genuine if the product or its contents correspond to the original condition and the information on the label.

Authentic goods are free from adulteration, especially with regard to composition, nature and varietal purity, geographical origin and manufacturing method.

Food fraud is of particular importance in this context. Here, consumers are deceived by deliberate product adulteration. Authenticity testing provides an opportunity to detect deception and food fraud attempts. Food law shall aim at the protection of the interests of consumers and shall provide a basis for consumers to make informed choices in relation to the foods they consume.

It shall aim at the prevention of: a fraudulent or deceptive practices b the adulteration of food c any other practices which may mislead the consumer. Authenticity testing is the analytical authenticity verification of food and feed with regard to its composition, purity, origin and production.

Using targeted methods , the food or feed sample is examined for a very specific adulteration which will either be confirmed or refuted. In case of non-targeted methods , the entire profile or specific characteristics of a food or feed sample are determined as a so-called physical-chemical or molecular fingerprint which will be compared with other reference data from a previously created database.

If the new profile image matches the reference profile stored in the database, the sample is authentic. Please contact your local Eurofins laboratory for more information about authenticity testing.

DNA fingerprinting techniques are used as molecular tools for authentication of mixed spices or herbs. Isotopic analyses and fingerprinting can be used for verification of organically grown food and geographical origin of various food products.

The concept of using authenticity testing to identify EMAs is shifting the fight against food fraud from reaction after they happen, to early detection and prevention, thus allowing the food industry to have control over the issue of food safety.

Research and technological advances are revolutionising the process of food authenticity testing, although they cannot be used to identify all types of food fraud. With the complexity of the global market and the addition of e-commerce, the safety risks of food fraud are likely to increase.

Therefore, there is always a need for sensitive and accurate authenticity methods to prevent food fraud from happening and help the industry to keep pace with new fraud tricks that may threaten the safety of the food supply chain.

Food fraud compliance and safety assessment The safety compliance of food products is covered under the European Commission General Food Law. Development of standard methods Multiple food fraud initiatives and programmes have been funded across the globe to define quality principles, develop analytical methods and set standards for food authenticity testing.

Food authenticity testing approaches There are two different approaches to food authenticity testing, depending on the type of fraud and level of vulnerability: targeted and non-targeted analysis. The GFSI defines seven distinct types of food fraud as the following: Substitution is the process of replacing a food, partly or totally, with a cheaper substance; for instance, mixing extra virgin olive oil with low grade oil.

The COVID pandemic has brought about far-reaching changes in the food industry, many of which impact food authenticity and testing. Massive disruptions in global food supply chains resulted in genuine food insecurity around the world and created new food safety issues. The mechanism by which our world feeds itself grows more complex every day.

Sustainable sourcing is taking center stage, the development of plant-based foods is booming and consumers are increasingly seeking out foods that address specific wellness goals, for example, a healthy gut microbiome. Each new development adds a new layer of complexity — and each new layer is an opportunity that fraudsters can exploit to their advantage.

This constant evolution of the nature of food will continue to fuel rapid change in industry regulations and standards, in turn driving the need for technological and methodological innovation that can deliver the updated and improved testing methods we will need to meet any new challenge.
