What is the cause of the α-Amylase Assay Reagent (R-CAAR4) and/or α-Amylase HR Reagent (R-AMHR4) turning yellow before addition of enzyme?

This problem is usually due to the quality of the water used to make up the reagent. Even trace amounts of α-amylase in the water (due to slight algal growth) will cause problems.  In such cases it is necessary to boil and cool the water before using it to dissolve the substrate.
