Abstract

Direct analysis of cane quality using core sampler and NIR Spectrophotometer was compared with indirect analysis of first expressed juice for raw sugar and final molasses distribution at CADPI. Based on the statistical analysis using Independent t-Test for two population means at 95% confidence interval, brix and pol%cane measurements from direct cane analysis have no significant difference compared with indirect analysis of cane. It was verified in the analysis that the same brix and pol%cane measurements can be generated from the two methods. Same statistical analysis was used to evaluate the computed theoretical yield based on direct and indirect cane quality measurement. From the analysis, it was shown that both theoretical yields were insignificantly different with each other. Even though both yields were fairly similar, there were problems encountered in indirect cane analysis: biased trash deduction, inaccurate sampling method, disagreeable assumptions used and impartial distribution of products. These problems were resoled using direct cane analysis. In addition, direct cane analysis have several advantages compared to indirect analysis which includes: no complex procedure to be performed, lesser equipment to be used, less manpower involved and faster generation of results. It was concluded in the study that direct cane analysis was better compared to indirect analysis in terms of man power requirement, length of sampling time and duration of analysis. For the improvement of raw sugar final molasses distribution, certain recommendations were also suggested.
