Getting tough on allergen testing
0%
People who are allergic to specific foodstuffs are about to get some official and technical help. South Africa is busy refining a new set of laws that will make food formulation and labelling much more specific and stringent. In step with this a local organisation called Food & Allergy Consulting and Testing Services (F.A.C.T.S.) has set up a laboratory that can verify allergen claims on consumer goods.

Hazelnut (Corylus avellana)
100%
Type 1 allergy to hazelnut is highly associated to pollen allergens from trees of the order Fagales (birch, alder, hazel, hornbeam, and oak). Prevalence of hazelnut hypersensitivity in tree pollen allergic patients ranges from about 70 to 90%. Allergic reactions to tree nuts are often severe, including anaphylactic reactions occurring after accidental ingestion. Hazelnut is responsible for about 13% of acute allergic reactions in tree nut sensitive patients. Frequency of hazelnut allergy is higher in adults than in children. Predictive values of skin tests and specific IgE are relatively low. Detailed information on prevalence, symptoms, and diagnostic features of hazelnut allergy as
well as cross-reactivities, molecular biological and allergenic properties of the major hazelnut and hazel pollen allergens are reviewed in tabular form. The major hazel pollen allergen (Cor a 1) as well as the major hazelnut 18-kDa allergen are cross- reactive to Bet v 1 from birch pollen. A
14-kDa hazelnut allergen cross- reacts with birch profilin (Bet v 2). Moreover, several heat stable hazelnut allergens have been identified which are independent of birch pollen. Hazelnut is a common ingredient in processed foods, mainly in confectionery products. Hazelnut oils which are not fully refined may potentially be a threat for nut allergic individuals.

IgE-Binding Patterns and Allergenicity of Mango Fruit Varieties
0%
Mango has become one of the most popular tropical fruits. It
is cultivated in more than 1000 strains. In the present study the four most frequently consumed varieties (Eden, Ngowe, Osteen and Tommy Atkins) cultivated in different continents were examined. In order to identify IgE binding allergens and
determine mutual cross-reactivities of the varieties immunoblot and enzymeallergosorbent test (EAST) inhibition were performed. Seven sera from patients with sensitization to mango fruit were used. All four varieties shared at least five allergens with Mr of approximately 14, 30, 40, 43 and 67 kDa. Results of EAST inhibition elucidated almost the
same inhibition curves and 50%-inhibition values for each
variety. In conclusion it could be shown that there were no
significant differences in allergenic potency among the
four mango strains.

IgE-Binding Properties of Recombinant Food Allergens
0%
Recombinant DNA technology is a common procedure to
produce allergenic proteins in vitro. To date, more than 40 food allergens from fruits, vegetables, nuts, milk and seafood have been expressed as recombinant proteins. Since recombinant proteins can be produced in large quantities and in controlled quality, they promise to be suitable tools for precise diagnostics and research applications. "Hypoallergenic" variants of these molecules with reduced or abolished IgE-binding activity may be candidates for immunotherapy of food allergies. Comparative investigations of recombinant food allergens and their natural counterparts may offer new insights into the structural basis of allergenicity. This review provides a
collection of data on recombinant food allergens and the spectrum of IgE-binding assays with which they have been tested. In addition, possible structural differences between
natural and recombinant food allergens are considered and
future diagnostic and therapeutic applications of recombinant food allergens are discussed.
