Rasio Determination Of Bleaching Earth And Phosphorus Acid In The Degumming And Bleaching Processes Of Crude Palm Oil

---

Oil from palm oil processing into crude palm oil generally still contains
impurities, so it is necessary to carry out a physical purification process which
includes pre-treatment and deodorization processes consisting of degumming and
bleaching processes to remove gum and other impurity components. The purpose
of this study was to determine the ratio of phosphoric acid in the degumming
process using phosphoric acid and the bleaching process using bleaching earth
on the quality of crude palm oil and degumm bleaching palm oil. The degumming
treatment used phosphoric acid with several concentrations of 0.5% and 1%,
which was compared with the control using bleaching earth with the percentage
of use of 0%, 0.5%, 1%, 1.5% and 2% (crude palm oil before processing).
degumming and after the degumming process). Analysis of the quality of crude
palm oil includes free fatty acids (FFA), DOBI, peroxide value (BP), phosphorus
content, water content, and iron content of crude palm oil and DBPO.
The results of this study indicate that the process after degumming using
phosphoric acid at a concentration of 0.5% produces ffa 2.53-2.98%), DOBI
(1.63-1.96), PV (0-1.64mg O2/100mg ), phosphorus (3.96-11.01 ppm), water
content (0.31-0.45), iron content (0.17-0.21). The degumming process using 1.0%
phosphoric acid produces 2.98-3.59% ffa, DOBI (1.68-1.91), PV (0-2.22 mg
O2/100mg), Phosphorus (2.24 -10.92 ppm), water content (0.31-0.88), iron
content (0.11-0.61). Which is effective for saving production costs in the treatment
with 0.5% phosphoric acid concentration and the use of 1% bleaching earth.
