An end point color standard based on reflectance, which can be described by the Munsell system of color notation, was developed for the modified resazurin test used to estimate bacterial counts in maple sap. In order to secure a reflected color, a sterile, nonfat milk solution was added to the clear sap-dye test solution to render it opaque. Results of tests made in accordance with this method are presented in graphic form.
