Abstract

Sucrose is important to be measured in food industry and Raman spectroscopy is preferred method for being fast, accurate, and non-destructive. Different concentration of sucrose was measured using Horiba’s modular probe-based Raman system. The signature peak of 824cm-1 caused by CH out-of-plane deformation was studied as a conventional fingerprint. There is a correlation between the intensity of each Raman peak and the final sample concentration. As one drops the other will follow linearly. Minimum concentration of 0.5% was recorded for short integration time of 0.5s. This finding can be revolutionary for food industry due to the high sensitivity and speed.
