Abstract
The behaviour of pectin methylesterase (PME, EC.3.1.1.11) was analysed in five new tomato cultivars for juices and tomato products. The thermal inactivation of this enzyme was evaluated in the range 73–88 °C and was found to be exponential. For each cultivar examined the logarithmic values of decimal reduction times plotted against temperature had a classic biphasic pattern featuring a sudden change in slope at temperatures exceeding 78 °C. The z values determined in the range 78–88 °C were much higher than those calculated from the log DT versus T °C in the range 73–88 °C.
