The Effect of Ultraviolet Radiation on Sucrose and Microorganism in Sugarcane

Mechanized sugarcane harvesting is an unavoidable development in sugarcane intelligence, however sugarcane collected by cut-off sugarcane harvesters is subject to microbial damage, which impacts sucrose storage. Ultraviolet rays are commonly utilized in the treatment of water. Microorganisms in water can be successfully killed by a combination of UV light and chloride ions. As a result, this study looked into the influence of UV radiation on sugarcane microorganisms as well as the effect on sucrose content. The UV light dose employed in the experiment was altered from 50.96KJ/m2 to 91.84KJ/m2, and microbial inactivation decreased by up to 98.8% (from 4.4log to 2.4log) when compared to the control group. At the same time, the sucrose content in the first 24 hours increased by up to 6.8%. Therefore, within 24 hours of harvesting, UV technology can maintain a lower microbial level in the billet while also better preserving the sucrose.
