Sucrose Losses in the Late Season.
In the late season, the range of FES target pH values was from pH 5.9 to 6.9. Up until the 2001 grinding season, many factories in Louisiana were indirectly targeting FES syrups _pH 6.0 through target CJ pH values, but this often gave actual FES pH values of 5.9 and lower (17). Similar to the early and midseason results, most hydrolysis occurred in the pre evaporators. However, unlike the midseason results, more hydrolysis generally occurred in preE2 than preE1 (Figure 5c) because on this sampling date the preE2 was less clean than preE1 (Figure 5c). This further confirms that, with respect to sucrose losses in evaporators, scaling effects override pH effects. Hydrolysis was only detected in the 1st evaporator body in late season, but this was relatively high and,as expected, decreased systematically (P < 0.05) with an increase in the target FES pH.
