Influence of the extrusion process on properties of barley dietary fibre
Original language description
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 °C 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 solublebeta-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,
