[Gluten content in special dietary use gluten-free products and other food products].

Gluten content of 22 special dietary use gluten-free products and 19 naturally gluten-free products was analysed by ELISA method. Gluten content in dietetic foods ranged from 5.19 to 57.16 mg/kg. Within the group of foods "gluten-free" by nature--gluten was not detected in rice and buckwheat groats samples, however in rice flakes and pearl millet gluten content ranged from 7.05 mg/kg- 27.51 mg/kg. Particularly high contamination with gluten (> 100 mg/kg) was detected in oat products what puts in doubt their usefulness in gluten-free diet.
