Abstract

Sterilization process is one of the keys to success in a Palm Oil Mill. In conventional palm oil mills that usehorizontal serilization, the fruit is heated in a closed vessel using pressurized steam at a pressure of 40 psiand a temperature of 140oC. The performance parameters that determine the success of the process inintermediate sterilization are pressure, temperature and time as well as steam requirements. This study aimsto determine the correlation between the area under sterilization graph represent the measurement of timeand pressure from every cycle of sterilization to oil losses in the condensate and empty bunch. The resultsshow that the higher the sterilization graph area which represents pressure and time, did not show significanttrend to the percentage of oil losses in the condensate and emptu bunch.

Abstract

Deterioration of bleachability index (DOBI) reflects the paleness index of crude palm oil which has the aim ofremoving the color (bleaching) that is less favored in oil, so DOBI is quite important to assist processing inrefining palm oil. This study aims to determine the DOBI value contained in crude palm oil derived fromdifferent levels of fruit maturity namely unripped fruit, riped and overripe on oil palm at 850 meters above sealevel, as well as its stability on heating for 0 and 24 hours. The results showed that ripe fruit has a DOBIvalue of 1.75 and has better stability compared to raw fruit and through ripe.
