Glutamic-oxaloacetic transaminase (GOT) activities in thermally processed beef samples were determined with a diagnostic test kit (no. 505P, Transaminases ALT/GPT and AST/GOT, Sigma Chemical Co.) procedure for possible use as indicators of cooking end-point temperatures (EPTs) between 71.1 and 82.2°C. GOT activity in the beef samples decreased curvilinearly with increasing EPTs. Activity was 3,450, 120, and 6 Sigma-Frankel units/ml (SFUs/ml) at 71.1, 75.6, and 82.2°C, respectively; a reduction of 99.8%. GOT values at 78.9,79.4, and 80.0°C, the critical range of EPTs in evaluating beef logs imported from South America, were 31, 17, and 14 SFUs/ml, respectively. Values within this range of temperatures differed significantly (P < 0.05); we suggest that residual GOT activity may be used as an EPT indicator for imported cooked beef products.

The variables, sample size and temperature of cooking media, were tested to determine their influence on myoglobin content and glutamic oxaloacetic transaminase (GOT) activities in bovine semimembranosus tissue thermally processed in a model heat treatment system. Data were obtained from 2.9 and 5.5 × 8.0 cm samples that were thermally processed to end-point temperatures (EPTs) of 62.8, 71.1 and 79.4°C in a water bath that exceeded EPTs by 2 and 20°C. Myoglobin denaturation differed (P < 0.05) by EPTs within samples, by sample size at the specified EPTs and by temperature of the heating media used to attain the EPTs within sample sizes. Similar variations at this probability level were observed in the analyses for residual GOT activities of the samples. Data indicate the inadequacies of analysis of these parameters in model systems that do not duplicate the actual process being evaluated.
