bioavid Lateral Flow Peanut incl. Hook line
Art. No.: BLH706-15
The Lateral Flow Peanut (Art. No. BLH706-15) with included hook line from bioavid is an immunochromatographic test for the sensitive and qualitative detection of peanut residues on surfaces (e.g. swab test for the hygiene control in food production lines), in cleansing and process water (CIP water) and food samples. The integrated hook line prevents false negative interpretation of high positive samples.
All for swabbing now included in the kit!
Although peanut (Arachis hypogaea) belongs to the legumes and not to the nuts, its taste and its usual consumption is similar to tree nuts. So to speak, peanut is one of the most popular “nuts” worldwide. Peanuts are very common ingredients of chocolate products and also consumed as snacks and in bakery products such as cookies. In 2017, 47 million tons peanut were produced worldwide, stating the importance of peanut as a food product.
With 25 %, the fraction of proteins in peanuts is very high. Many of these proteins are known for being allergenic, such as Arachins and Conarachins, which are contained in relative high amounts. Peanut is also one of the five foods, which are the most frequent cause of food allergies. Allergies against peanuts are among the most severe allergies and can lead to life-threatening anaphylactic shocks. Consumption of probably less than a milligram of peanut can induce allergic reactions in very sensitized individuals. Therefore, labeling of peanut containing products is very important and compulsory in the USA and the European Union as well as in many other countries. The main threat for sensitized individuals is contamination of peanut in food, which is intended to be peanut-free (e.g. peanut traces in chocolate, which should not contain peanuts). Therefore, it is important to test foods, which may have been contaminated during their production process, for the presence of unintended traces of peanuts.
If an allergen is present as a product ingredient, it must be indicated on the food label according to the regulation (EU) No. 1169/2011. Similar regulations exist e.g. in the USA, Canada, Australia and New Zealand.
