摘要：

An assay, based on binding of the dye 2-(4'hydroxyazobenzene)-benzoic acid (HABA) and widely used in studies of avidin in liquid systems, was combined with an aqueous extraction method and used to assay avidin in cooked egg white. The method was validated for linearity of response to increasing avidin concentrations, precision, accuracy, recovery and sensitivity. Mean residual avidin activity in fried, poached and boiled (2 min) egg white was 33, 71 and 40% of the activity in raw egg white.
