CEREALS, BIRCH POLLEN-RELATED; MUGWORT RELATED IN YOUNGSTERS AND ADULTS
A cow's milk, soy or hen's egg challenge can be prepared according to the recipes for infants and small children.
MS = measuring spoon
flavouring agent: orange flavour by SHS
colouring agent: beta-carotin
The challenge dose is related to the average daily intake of the relevant age group. Whether the food challenge is performed as titrated challenge or with the total amount of food depends on the patient's history and the expected clinic reaction.
| Ingredients: | How to be prepared: |
| cereal challenge in small children (older children, youngsters and adults) placebo (total amount) 20 (50) g rice wholemeal flakes 20g Sinlac 150 (140) ml water (boiled and cooled down) 1/2 MS flavouring agent* colouring agent*, if needed verum (total amount) 20 (50) g cereal wholemeal flakes (wheat, rye, oat) 20 g Sinlac 150 (160-180) ml water (boiled and cooled down) 1/2 MS flavouring agent* colouring agent*, if needed | mix rice flakes and Sinlac, stirr in water add flavouring agent and colouring agent and mix well blending is possible mix cereal flakes and Sinlac, stirr in water add flavouring agent and colouring agent and mix well blending is possible |
| challenge with birch-associated foods (apple, carrot, celeriac, hazelnut) if an oral allergy syndrome is present, the relevant food item is eliminated both challenges (placebo and verum) have to be performed with sun glasses for better blinding | |
| placebo (total amount) 210 ml water (boiled and cooled down) 40-60 g Sinlac 1/2 MS flavouring agent* colouring agent*, if needed 30 g rice wholemeal flakes verum (total amount) 120 ml water (boiled and cooled down) 30-40 g Sinlac 150 g birch-associated foods (50 g apple (Granny Smith), 50 g carrots, 50 g celeriac) 10 g hazelnuts 1/2 MS flavouring agent* colouring agent*, if needed (Granny Smith), 50 g carrots, 50 g celeriac) 10 g hazelnuts 1/2 MS flavouring agent* colouring agent*, if needed | stir Sinlac in water add flavouring and colouring agent in order to imitate the verum's taste and colour place in the fridge add rice flakes shortly before food challenge stir Sinlac in water and place in the fridge, blend birch-associated foods and add to the pulp (this has to be done shortly before the pulp is served, otherwise the apple looses its allergenicity) add flavouring and colouring agent for blinding and serve immediately |
| challenge with mugwort-associated foods (celeriac, celery,carrot, tomato without kernels) if an oral allergy syndrome is present, the relevant food item is eliminated both challenges (placebo and verum) have to be performed with sun glasses for better blinding | |

Blinding of other foods:
MS = measuring spoon
flavouring agent: orange flavour by SHS
colouring agent: beta-carotin
| yeast | in pancake (for placebo use baking powder; blinding is easier, if the pancake has a vegetable filling) |
| meat | use textured vegetable protein as placebo and serve in spicy sauce use tolerated meat and mince together with suspected meat, serve as hamburger |
| thuna / other fish | serve in vegetable soup (liquidized) and use seaweed-vegetable soup as placebo |
| chocolade | use carob as placebo and serve as flummery, cake or biscuit |
Foods as basis for blinding, especially in children:
Foods with strong taste and colour, ideal for blinding:
• flummery
• hamburger
• ice-cream
• rice-pudding
• apple-sauce
• milk shakes
• mashed potatoes
• black currant juice
• beetroot juice
• cocoa
• peppermint oil
Placing the food in the fridge before serving it, helps better blinding.
