A new program for interactive computing of physical properties of sucrose, sucrose solutions and any other substances by modelling, simulation and balance calculations was developed. The main data source for the database is monograph Sugar Technologists Manual from Bubnik, Z., Kadlec, P., Urban, D., and Bruhns, M. (1995) [Sugar technologists manual. Chemical and physical data for sugar manufacturers and users. Berlin, Germany: Bartens Pub. Co.]. The computer database consists of two programs. The first one-SugarRes-serves to make records in the database file, and the second one-SugarProp-searches and retrieves parameters from the database file, calculates and e.g. shows any other information. The developed program offers a collection of data dedicated to properties of sucrose, its solutions and technical solutions, other saccharides, intermediates and many other substances. The user of the program can browse the literature references and equations for given calculation, including validity range of input and output values. Program SugarRes can be used as an universal tool for developing of any similar database systems. (c) 2005 Elsevier Ltd. All fights reserved.
