Primary Outcome Measures:
  • Number of participants detecting sensorial differences between the active materials (containing the allergens cow's milk, hen's egg, soy, wheat or cod) and the placebo materials [ Designated as safety issue: No ]
    The present study aimed to validate new recipes for low-dose double-blind placebo-controlled food challenges in school children, by assessing that no sensory differences between the active materials containing cow's milk, hen's egg, soy, wheat or cod, and the placebo materials could be detected by test panels.
