The invention provides an improved procedure for the precise quantitation of organic oxidants in a solution with hydrogen peroxide in which the peroxide is removed by the addition of catalase to scavenge the same. Surprisingly, the catalase does not affect the organic oxidant, and the procedure can accurately quantitate even minute amounts of the organic oxidant. The inventive method is especially effective in quantitating peracid generated enzymatically, although it can be used for chemically generated organic oxidants.

Method for quantitating organic peracid using catalase

A perhydrolysis system or activated oxidant system for in situ generation of peracid in aqueous solutions is disclosed including a protease enzyme, a source of hydrogen peroxide and an ester substrate having the general structure ##STR1## where R and R' are alkyl groups unsubstituted or substituted with at least one functional group. Preferred substrates are defined which are preferably chemically non-perhydrolyzable. Processes for bleaching and peracid production are also disclosed.
