[Dietary fiber in flour and concentration of rapeseed protein]

Crude fibre content of rapeseed meal and protein concentrate, obtained from raw and steamed rapeseed, was determined. Moreover, in the protein concentrate and in crude fibre the levels of calcium and magnesium were measured. The protein concentrate contained more crude fibre than the meal. Polysaccharides accounted in crude fibre from meal for more than 80% of its total composition, and in crude fibre from the protein concentrate for only ca. 70%. Steaming of rapeseed led to an increase in calcium and magnesium contents of crude fibre from meal and decrease in the protein concentrate.
