Color Measurement of Solutions with the UV-1900 Spectrophotometer: Differentiating the Colors ofJapanese White Dashi Soup Bases

Introduction

Food comes in a variety of colors. The color of food is one of the important elements in its taste and presentation. Although there is a sensory aspect to color, it can be expressed objectively as numerical values by measuring its transmission spectrum with an ultraviolet-visible spectrophotometer and calculating the color values. This makes it possible to compare colors between samples. In this study we measured various kinds of white dashi soup bases (Japanese white soy sauce-based soup stock) from different manufacturers and determined their color values, as described below.
