Bioavid Cashew Hook Line Cashew Nut Allergen Rapid Test

The Bioavid Lateral Flow Cashew with included Hook Line is an immunochromatographic test for the sensitive and qualitative detection of cashew residues on surfaces (e.g. hygiene control in food production lines), during cleaning, in process water (CIP water), and in food samples. The integrated Hook Line prevents false-negative interpretation of highly positive samples.

• Rapid test for the sensitive and qualitative detection of cashew residues on surfaces.
• Ideal for hygiene control in food production lines, process water (CIP water), and food samples.
• The integrated Hook Line prevents false-negative interpretation of high-positive samples.
• Fast and easy method to qualitatively detect cashew residues in food samples.
• Very simple and can be performed by untrained personnel.
• Can be stored at room temperature.
• Ideal tool for immediate testing in production facilities.
• Everything for swabbing is included in the kit.
• Contains the complete equipment for the analysis.
• Fast and reliable results in 10 minutes.

Cashew proteins can be present as an ingredient or as a contaminant in raw and processed products. The presence of undeclared cashews poses a potential risk to patients allergic to cashews. Nut allergy is the leading allergy worldwide. Besides walnuts, cashews are the second most common nut allergy. Cashews are a very potent allergen and must be avoided by allergic patients.

Food production lines and the food itself must be free of residues to prevent these allergic reactions. The effectiveness of cleaning can be verified by using a lateral flow method for the detection of cashews. According to Regulation (EU) No 1169/2011, cashews must be listed on food labels because they can cause allergic reactions. Similar regulations exist, for example, in the US, Canada, Australia, and New Zealand.

Dip Sticks are a user-friendly method and ensure a fast and reliable analysis. Applying the Bioavid Dip Sticks is very simple and can be performed by untrained personnel. All Bioavid test kits can be stored at room temperature and are therefore an ideal tool for direct testing in production facilities. The Bioavid test kits contain the complete equipment for the analysis.

Sample preparation
• Surfaces (swabbing): wipe the surface with a cotton swab moistened with PBS and rinse the swab in the reaction vessel.
• Food samples: homogenize the food sample and centrifuge or filter.
• Liquid samples (e.g. CIP water): no preparation.

LOD (detection limit)
• Cashew nuts (in water): 1 ppm
• Spiked zero matrices (depending on species): 10 - 60 ppm
• Surfaces (smears): 0.08 µg cashew/cm²
• CIP water: 1 ppm
