December, 1994 Copyright © 1994, by Sugar Processing Research Institute, Inc. All rights reserved ISBN 1-883326-02-8 PREFACE The 1994 Sugar Processing Research Conference is one of a series of Conferences held in alternate years to provide a forum for exchange of information among technical leaders of the sugar industry and to report on new and noteworthy developments. The Conference was sponsored by Sugar Processing Research Institute, Inc. (SPRI) The Southern Regional Research Center, Agricultural Research Serv.ice, U.S. Department of Agriculture, contributed in kind to the organization of the Conference. The program for this conference was arranged by Margaret A. Clarke. The Conference Coordinator was Shirley T. Saucier. These Proceed- ings were edited by Margaret A. Clarke with editorial assistant Beryl Ann Borel. The series, Proceedings of the Sugar Processing Research Confer- ence, of which this is the seventh issue, continues the Proceedings of the Technical Sessions on Cane Sugar Refining Research, which was published every other year from 1964 to 1980. For individual copies of this volume as well as back issues of the former series as long as the supply lasts, write to Sugar Processing Research Institute, Inc., 1100 Robert E. Lee Blvd. New Orleans, LA 70124. Before 1986, Proceedings were publishe,d by the Agricultural Research Service, U.S. Department of Agriculture. Since 1988, Proceedings have been published by the Sugar Processing Research Institute. Margaret A. Clarke Managing Director Sugar Processing Research Institute, Inc.
