Maple Syrup Color Analysis using the Shimadzu UV-2600 UV-Vis Spectrophotometer

Introduction

UV-Visible spectrophotometry is a valuable tool in the laboratory for measuring the properties of various liquids and solids. One of the most common applications for QA/QC environments is Color Analysis and being able to assign a color value to finished products. The color value of a material can be obtained by collecting a % transmittance or reflectance spectrum of the sample under consideration. The Shimadzu UV-2600 spectrophotometer is ideal for making accurate color measurements due to the large photometric range of 5 abs. units. Therefore, dilution is not required for highly absorbing samples such as maple syrup. Samples can be analyzed neat without further dilution. The application illustrates the use of Shimadzu Color Analysis Software and the UV-2600 spectrophotometer for quick and easy spectral acquisition and interpretation into a meaningful color value.
