Abstract
A stable asparaginase solution is disclosed. In one aspect, drinking water is treated to reduce the level of chlorine to enhance the residual enzyme activity of asparaginase. The treatment can occur by removing chlorine constituents or by supplying additives that reduces the level of chlorine. Additives can include reducing agents and chlorine scavengers. Removal technologies can include use of activated carbon, ion exchange, and air stripping.
