After a series of extractions and separations, hemicellulose B was one of several by-products composed mainly of pulp and usually disposed of from a cannery. The recovery of hemicellulose B was about 10%, dry weight. A water-soluble fraction was prepared free of insect fragments. Further studies were made to compare the effectiveness of enzyme hydrolysis vs acid hydrolysis of hemicellulose B and to elucidate its composition. Results showed Rhozyme HP-150 to be more effective than Pectinol 10M or 1.OM H/sub 2/SO/sub 4/ in hydrolyzing the pineapple hemicellulose B. The hydrolyzate contained pentoses and hexoses approximately in a 1:1 ratio. The sugars were: arabinose 8.5, ribose 11.0, xylose 35.0, mannose 9.2, galactose 23.6, and glucose 12.7% average by weight. The hemicellulose B has potential use as a thickener in syrups and beverages.
