Effect of lipid extraction methods on total dietary fiber and nonstarch polysaccharide contents of selected nuts and seeds
Three extraction methods were used to remove lipid materials from 8 edible nuts and seeds before analysis for their total dietary fiber (TDF) and nonstarch polysaccharide (NSP) contents. Portions of ground materials were extracted by: n-hexane; followed by 80% methanol; n-hexane-acetic acid (95 + 5; v/v); and supercritical carbon dioxide. Defatted samples were gelatinized in […]
