"Five Czech spring barley samples were tested. Two of them (KM 2084, AF Lucius) were naked barleys with a standard starch composition. The remaining three varieties (KM 2624, KM 2460-1, KM 2460-2) were hulled waxy barley with higher -glucan and arabinoxylan ? content. Extrusion was carried out with a twin screw extruder at 130 \u00B0C with addition of water (20%) and a screw speed of 220 rpm. Soluble beta-glucans were extracted using Temelli's (1997) procedure with some modifications. Molar masses of soluble beta-glucans were determined by GPC with a refractive index detector. Regardless of the starch type, extrusion had positive effects on the raise of the beta- glucan and protein content, but starch and fat content decreased. The content of insoluble dietary fibre (IDF) decreased in extrudates from samples KM 2084, KM 2624 and KM 2460-1 and on the other hand increased in the samples KM 2460-2 and AF Lucius. In contrast the soluble part of the dietary fibre of the samples KM 2084, KM 2624, KM 2460-1 and AF Lucius was increased and of the sample KM 2460-2 was decreased. Only in the extrudate from cultivar AF Lucius the content of both IDF and SDF was higher in comparison with natural barley grain. The variation of the total dietary fibre content (TDF) of the samples was very prounounced and different. However the difference between TDF content in flour and in extrudates was very low (only up to 1%)."@en . . "Influence of the extrusion process on properties of barley dietary fibre" .
