摘要
Abstract
In this paper, the UV-visible absorption curves of different batches of refined white granulated sugar intermediate material (the base material concentration, the intermediate crystallization and the final enrichment of three stages of original liquid) were determined. The correlation model and mixed model between the absorbance value of the ultraviolet visible band and the final product color value were established in the ways of Unitary Linear Regression (ULR), Multiple Linear Regression (MLR) and Stepwise Regression Analysis (SRA), the hybrid model had best prediction accuracy when predicting the color values of products using these models. The results of three methods were compared comprehensively, the model of intermediate stage using SRA, C=12.60A220+12.49A300+12.35, was considered to be most appropriate when factors of workload, correlation and prediction accuracy were taken into account. Using the results of the univariate regression analysis model, the absorbance values of the different intermediate materials were obtained. The final product color value would fall within the range of less than 25 IU at 95% confidence level.关键词
