Abstract

Sugar losses after harvest is one of the major problems of sugar processing units in many countries especially where milling is extended during a period of high ambient temperature. A study undertaken on the magnitude of post-harvest sucrose losses and its relationship with two enzymes viz. invertase and dextransucrase during late milling season showed significant reduction in CCS and increase in enzyme activities. The loss in CCS was nearly 60 percent in untreated cane compared to 27 percent in QUAT based chemical treatment after 240 hours of storage. There was marked increase in acid invertase and dextransucrase activities with the passage of time, however QUAT based formulation treatment recorded appreciable reduction in the enzyme activities. The study has indicated that it is possible to minimize post harvest sugar losses during late-season by application of QUAT based formulation.
