Allergenicity of barley starch syrup

Tuesday, 01 September 2009 15:10

A study has been conducted to determine whether enough protein remains in barley starch syrup to invoke an allergic reaction in individuals with allergy to wheat, barley, rye or oats. Fifteen children with allergy to these cereals, confirmed by double-blind placebo-controlled food challenge, took part in the study.

When exposed to cereals, seven (47%) of the children showed immediate type reactions, and eight (53%) showed delayed type reactions. When exposed to barley starch syrup in double-blind placebo-controlled food challenges and skin prick testing, none of the children showed any objective signs of allergy.

The researchers concluded this study confirmed with 98% confidence that at least 90% of the patients with verified allergy to cereals will not react with allergic symptoms to barley starch syrup.
