Evaluation of colorimetric pH strips for wild animal meat using image analysis.

Anim Sci J 2021 Dec;92(1):e13602

Division of Applied Entomology and Zoology, Central Region Agricultural Research Center, National Agriculture and Food Research Organization, Tsukuba, Japan.

Colorimetric pH strips (MColorpHast™) are very convenient to use, but the decision of pH is based on an individual's color perception and is, therefore, subjective. We developed a pH calculation program for the image of coloring strips on CIE1976 (L*a*b* color space), which slightly underestimated human judgment as the color of pH darker. This image analysis and three individuals' judgments were used for evaluating the strip's features for various qualities of meat from wild animals, and the results were compared with the assessments based on potentiometric pH.
