Cashew tree (Anacardium occidentale) is a tropical evergreen tree that belongs to the Anacardiaceae family and it produces cashew seed and cashew apple. These seed shells have been used to yields derivatives which are useful in many applications such as paints, waterproofing and lubricants. Cashews have a lower fat content when compared to most other nuts, approx. 82% is unsaturated fatty acids and around 66% of this is heart-healthy monounsaturated fats. Studies have indicated that people allergic to cashew are also allergic to pistachio (process called cross-reactivity), both of these nuts are botanically related. Cashew food allergies are usually linked to the presence of IgE antibodies which are directed against the major seed storage proteins in Cashew (namely 13S globulin proteins and 2S albumins). It has been found to frequently induce symptoms of food allergy, hypersensitivity reactions and atopic dermatitis in individuals that are sensitised. The following cashew ELISA assay method is a highly sensitive detection system that is able to quantify cashew residues in cereals, cookies, chocolate and ice-cream.
Cashew ELISA kit is designed for determining quantitative levels of cashew in food (such as chocolate, ice-cream, cereals and cookies). This assay has a minimum analytical sensitivity limit of 0.2 ppm.
The minimum detection sensitivity level of cashew using this cashew ELISA kit was 0.2 ppm. The standard assay range for this kit is 2.0 – 60.0 ppm.
