+Read MoreFood Allergy?
As with any allergy, a food allergy develops when the immune system attacks a normally harmless substance and creates specific antibodies for this substance. From this point on, whenever the food allergy sufferer eats the food to which they're allergic, the antibodies respond by releasing histamine, which causes allergic symptoms to appear.

FOOD ALLERGIES AND INTOLERANCES
A food sensitivity is an adverse reaction to a food that other people can safely eat, and includes food allergies, food intolerances, and chemical sensitivities.
Food allergies are sensitivities caused by a reaction of the body's immune system to specific proteins in a food. Current estimates are that food allergies affect as many as 6% of young children and 3% to 4% of adults.
In allergic individuals, a food protein is mistakenly identified by the immune system as being harmful. The first time the individual is exposed to such a protein, the body's immune system responds by creating antibodies called immunoglobulin E (IgE). When the individual is exposed again to the same food protein, IgE antibodies and chemicals such as histamine are released.Histamine is a powerful chemical that can cause a reaction in the respiratory system, gastrointestinal tract, skin or cardiovascular system. In the most extreme cases, food allergies can be fatal. Although any food can provoke an immune response in allergic individuals, a few foods are responsible for the majority of food allergies.

German Government Official Methods Board Points the Way Forward: Launch of a New Working Group for Mass Spectrometry for Protein Analysis to Detect Food Fraud and Food Allergens
The detection of food fraud and undeclared food allergens is one of the major challenges for competent authorities. Because adulterations are continuously adapted to the methods used to uncover them, the accomplishment of this task has become increasingly difficult over time. In recent years, various new promising methods for the detection of multiple food adulterants and multiple food allergens have been developed. Some of them utilize LC–MS to identify specific marker peptides.

Investigation of Reduced ELISA Recovery of Almond and Hazelnut Traces from Roasted Nut Samples by SDS-PAGE and Mass Spectrometry
Western society is facing an increase in the number of food-allergic individuals, with rising incidence in the past years. Therefore, allergen-free food and accurate and reliable analysis of allergen contamination are essential for the protection of consumers. Yet, there is limited understanding on the effect of food processing on allergenicity and on the ability of available methods to detect trace contamination in processed food. Available studies addressing this have relied on sample processing on a laboratory scale.
