Allergen testing plays a crucial role for food businesses to detect the presence of allergens in food which might cause allergic reactions in consumers. By providing allergen-free products, food Companies can help secure the health of consumers, gain their trust, and enhance their reputation in the market.<\/p>\n
Allergens are substances that can trigger allergic reactions in individuals with specific sensitivities or allergies. These reactions can range from mild discomfort to life-threatening anaphylaxis.<\/p>\n
Hence, it is important for food organisations to opt for accurate testing methods to ensure no harmful allergen goes undetected.<\/p>\n
To help food businesses in Australia choose the right allergen testing method, we have encapsulated the popular, authentic allergen tests used to detect allergens in Australia.<\/p>\n
PCR and ELISA methods are the most common types of allergen testing used for detecting the presence of food allergens. These methods are rapid, simple, and economical to utilise in food production facilities, and they may be applied to a wide range of foods.<\/p>\n
In short, the ELISA method detects the specific protein molecule of the allergen. PCR detects the DNA molecules of allergens. It cannot trace products that do not have DNA.<\/p>\n
Below we have described both ELISA and PCR and other allergen testing methods used in Australia.<\/p>\n
For quick in-plant monitoring of certain food allergies, a qualitative immunochromatographic technique is used, which is called as the Protein Rapid Test. These quick, simple tests may be used for clean-in-place (CIP) final rinse water, environmental swab samples, raw ingredients, and finished food items. They are designed for reliable identification of processed and unprocessed allergen proteins.<\/p>\n
The most popular and preferred approach for identifying food allergies is the Enzyme-Linked Immunosorbent Assay (ELISA) method. Through the binding of antibodies to the allergen, ELISA techniques identify the allergen protein molecule. The samples are treated, and their colour is altered to prove the allergen protein’s presence.<\/p>\n
However, ELISA techniques are not able to deliver accurate findings in certain circumstances. Some food varieties, such chocolate or other nuts, might produce cross-reactivity or interfere with the ELISA procedure.<\/p>\n
Additionally, for cooked or heated foods, the ELISA approach might not be appropriate since the protein molecules might be damaged or altered. Despite the allergen perhaps being undetectable, sensitive people may still experience issues.<\/p>\n
Polymerase Chain Reaction (PCR) testing is used as an alternative technique for ELISA method. PCR is utilised in cases where the allergen is not found. As a result of its increased sensitivity, PCR can detect allergen DNA molecules in both raw and cooked foods without being harmed by heat. Since the DNA is separated from other proteins or organic matter before analysis, PCR procedures are not affected by the interferences that influence ELISA-based techniques. On all products, nevertheless, PCR cannot be used. Since these products don’t contain DNA, PCR cannot be used to test them, such as oil, milk, or egg whites. ELISA-based testing must be used to detect allergens in these goods instead.<\/p>\n
Traditionally, the presence of allergens in food has been determined by the ELISA and PCR techniques. These technologies have been established for many years and are routinely used in most laboratories and manufacturing facilities’ testing for the presence of food allergens. The benefit of these technologies is their wide availability and ease of use. Furthermore, over the years they have been proven to work for a wide range of matrices.<\/p>\n
However, in the past few years, scientists have observed that in certain processed foods like yoghurt-based dressing, cookies bakery products, cookies and in one case chocolate, the ELISA technique did not detect the presence of a significant amount of milk and egg.<\/p>\n
But with the help of Liquid Chromatography coupled with Mass Spectrometric detection (LC-MS\/MS) technique for allergen testing, the scientists were able to demonstrate the substantial levels of egg and milk, which went undetectable by ELISA in bakery items. Hence, this test is used for the above types of foods.<\/p>\n
Following tryptic digestion, screening for complete proteins utilising LC-MS\/MS with high-resolution accurate mass (HRAM) apparatus is possible. Multiple allergens may be identified using LC-MS\/MS, which also has lower false negative rates, higher sensitivity, specificity, precision, and dependability.<\/p>\n
LC-MS\/MS is the appropriate instrument for both qualitative and quantitative investigation because it may only need one injection as a result.<\/p>\n
One of the most successful and efficient ways to identify the presence of proteins, including allergenic proteins from eggs, milk, gluten, soy, and peanut, is to utilise a simple and easy-to-use protein sensitivity swab test.<\/p>\n
With the use of this very sensitive protein detection method, a variety of probable allergens may be tested in a single swab. The swab is rolled over the surface, activated, and quickly incubated. The findings of the test can be seen right away.<\/p>\n
Protein swab tests are one of the most dependable tools in your Allergen Management Plan toolbox because of their high degree of accuracy. Competent workers in the food manufacturing industry can easily complete this test.<\/p>\n
