35 45 the residual activity of apple pectin methyl esterase under atmospheric pressure exhibits some fluctuations after mild heat at 35, 45, and 55°C, it seems that apple pectin methyl esterase is activated at 35 or 45°C, but the two temperatures have no significant effects on the residual activity as compared to the control sample, although the residual activity of apple pectin methyl esterase is reduced at 55°C as the treatment time increases, and a significant reduction of the residual activity is obtained after 30 min, the maximum reduction of apple pectin methyl esterase activity is still less than 20% for 60 min Malus sp.
