ABSTRACT

This research was conducted to improve the hygiene of mill station area by adjusting the pH condition of the mill juices in order to prevent sucrose inversion. The clear solution of milk of lime with concentration of 3o Beaume was used for udjusting the pH of the mill juices. The clear solution of milk of lime was distributed individually to the drawing tanks of mill juices. The pH target of the mill juices is between 6.3 to 7.0. The results showed that there were an increase of the ratio of mixed juice and fisrt expressed juice from 93.30 to 94.96 ; a decrease of the formation of reducing sugar about 93,11%; an increase of the brightness of clear juice about 26,14%; a reduction of the lime content of clear juice about 10,57% ; a reduction of the amylum content on mixed juice about 25,29% and no dextran formation between the first expressed juice to the mixed juice. Some advantages of massecuites physical properties are also described in this paper.

Key words : milk of lime clear solution, inversion, hygiene, pre –defecation.
