Description
Australian sugar factories designed to achieve high levels of energy efficiency experience substantial juice degradation in evaporator units (from high temperature and long residence time) that results in low sugar yields and quality, corrosion of equipment and causes significant financial loss. This thesis provides an extensive study into understanding the chemistry aspects of sugarcane juice degradation during evaporation and defining practical strategies to reduce the subsequent impacts of these degradation processes. The major findings included identifying key operational and compositional parameters that increase sucrose degradation, and developing new juice clarification process and pH control process to minimise sucrose degradation.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
