Abstract
Methods for the isolation of certain biologically important polymers from parenchymal cell-containing plant materials, especially sugar beet and citrus pulp, are disclosed. Hydrolysis under extremes of pH and under elevated temperatures for short reaction periods with physical shearing are disclosed which lead to the isolation of hemicellulosic and cellulosic components of such plant materials without substantial degradation thereof. Novel cellulosic products and vegetable gums are provided having unique physical, chemical and rheological properties.
