Food additive Preparation of epicutaneous skin test solution
Gelatin Dissolve 1 teaspoon (5 grams) of gelatin powder (plain or flavored) in 5 mL of normal saline.[1]
Carmine Make 10% solution of carmine powder in phosphate-buffered saline. Agitate at 4°C for 2 hours. Dialyze against purified water, and filter through 0.22 micron filter.[2]
Annatto Additive-containing food (Gouda cheese) and a commercial preparation of annatto dye, diluted 1000-fold was used.[3]
Guar gum Additive-containing food (a meal substitute) and guar gum preparation (no details provided).[4]
Psyllium Extract commercially available.
Carrageenan 0.4% weight/volume sodium carrageenan.[5]
Potassium metabisulfite Maximum concentration of 1 mg/mL.[6]
Yeast (Saccharomyces cerevisiae) Extract commercially available.
Erythritol 2, 20, and 200 mg/mL in distilled water.[7]
Carob bean gum Carob gum at 5 and 25 mg/mL. Can use raw carob gum, boiled carob gum, and carob bean extract for skin testing also.[8]
