Water-holding capacity (WHC) is a critical indicator of beef quality. Several conventional test methods have high cost or spend more time. In this study, a rapid detection method was developed to measure WHC by modified test paper. The test paper was modified by cobalt chloride for its color turned from blue to red after contacting with water. When the test paper was attached to the surface of meat sample, its color would change. The time of color changing was related to WHC. A prediction model was built. The prediction accuracy was 90 % and the detection time was less than 1 min. The results of scanning electron microscope (SEM) analysis showed that the three-dimensional network structures of the test paper were more compact and homogeneous. Accordingly, the modified test paper exhibits a more stable property and can be used for other meat products.
