A simple digital imaging method for measuring and analyzing color of food surfaces

This paper presents a simple method that uses a combination of digital camera, computer, and graphics software to measure and analyze the surface color of food products. The method has also the advantages of being versatile and affordable. The images of the food products can be displayed on computer screen or printed on paper for qualitative analysis of color and structure. Quantitative information such as color distribution and averages (in terms of L*, a* and b* values) can also be determined readily. (C) 2003 Elsevier Ltd. All rights reserved.
