Pectic polysaccharide fractions of high molecular weight, resistant to further degradation by pectolytic, hemicellulolytic, and cellulolytic enzymes, were isolated from potato fibre and from pear, carrot, leek, and onion tissue by the liquefaction process. The fractions, referred to as modified hair
## Abstract Pectic substances have been extracted from plant material (a pasture legume, __Stylosanthes humilis__) by homogenisation with a solution of ammonium oxalate and oxalic acid and subsequently hydrolysed with polygalacturonase. The galacturonic acid produced was determined by a modified ca
