ResumoABSTRACT A certified, food grade wheat bran (#R07–3691) obtained from the American Association of Cereal Chemists was analyzed using a fractionation procedure. This method includes estimation of cold and hot water‐soluble biopolymers as well as total pectic substances, hemicellulose, cellulose, and Klason lignin. Quantitative and qualitative analysis of the carbohydrate polymers was achieved by gas‐liquid chromatography. The polymers were hydrolyzed with acid, derivatized to form the respective alditol acetates, and analyzed. The wheat bran was found to contain 0.79 ± 0.09% cold and a trace of hot water‐soluble neutral polysaccharides, 2.17 ± 0.09% total pectic substances, 28.45 ± 1.00% hemicellulose, 9.84 ± 0.75% cellulose, and 2.87 ± 0.21% Klason lignin. These values agree with those estimated by other methods where available.
