摘要： To the milk or other catalase-containing liquid, mainly of biological origin, are added a reagent comprising a substance which releases hydrogen peroxide in the presence of a substance available in the milk or other liquid, and another reagent which, upon oxidation by hydrogen peroxide, yields a color reaction, the catalase content being determined qualitatively and quantitatively with the aid of the hue of the color thus produced. A device for carrying out this assay method comprises the two reagents separated physically from each other by a space through which the generated hydrogen peroxide can diffuse and which is capable of admitting the milk or other liquid.
