Quantitative tests for catalase activity find their greatest usefulness in examination of finished product. For this purpose gasometric methods (86) or chemical methods based upon measurement of residual hydrogen peroxide (2) may be used. In the use of these quantitative methods it might be well to observe the precaution of removing the skins. Qualitative and semiquantitative methods for the estimation of peroxidase activity have been recommended on the principle that peroxidase is a very heat-resistant enzyme, and therefore permits a greater margin of safety in blanching.
