Color Measurement of Food- Color Measurement in Sugar and Juice -

Color is a sensory-related phenomenon, but by conducting measurement of food samples using a spectrophotometer to express the color as an objective numerical value, it is possible to compare color quantitatively among multiple samples.
Here, we conducted measurement of sugar and juice samples to determine their color values. For sugar, we used castor or "superfine" sugar, soft brown sugar and brown sugar, etc. as samples, and conducted measurement using a powdered sample holder to compare the color among the samples. For juice, we measured the difference in color between vegetable juice and fruit juice using a screw-cap vial to conduct the measurements and investigate the differences in color.
