The crystallization process of these sugars is essential in the food industry, as it affects the texture, shelf life, and sensory properties of many food products. Currently, X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) are commonly used methods for studying the structure and composition of sugar crystals. However, Raman spectroscopy has emerged as a powerful analytical tool in recent years, allowing for the rapid and non-destructive analysis of crystalline materials.ObjectiveThe main objective of this study is to investigate the application of Raman spectroscopy in the crystallization process of A-K sugar. Specifically, we aim to:1. Characterize the structural properties of A-K sugar crystals at different stages of the crystallization process using Raman spectroscopy.2. Determine the effect of crystallization conditions (i.e., temperature, concentration, and stirring rate) on the Raman spectra of A-K sugar crystals.3. Compare the Raman spectra of A-K sugar crystals with those obtained using XRD and FTIR to evaluate the suitability of Raman spectroscopy for the analysis of sugar crystals.MethodologyThe crystallization process of A-K sugar will be carried out under controlled conditions, and the resulting crystals will be analyzed using Raman spectroscopy. The Raman spectra will be collected using a high-resolution Raman spectrometer 精品文档---下载后可任意编辑equipped with a laser excitation source. The parameters to be varied during the...
