CLAIMS

1. A process for producing a refined palm fruit oO having a reduced 3-MCPD content, the process including the steps of:

a, washing oil palm fresh fhrit bunches (FFB) with water having a temperature of 0 to 100°C to produce washed οΠ palm FFB;

b. subjecting the washed oil pahn FFB to sterilization, threshing, digestion and pfcssing to produce a crude palm fruh oil;

c nVgumming of the crude palm fruit oil to produce a degiimmnd palm fhrit oil;

d. bleaching of the nVgnrnmrd palm fruit oil with a bleaching adsorbem to produce a bleached pahn fruit oil; and

e. (feodoiiiing the bleached pahn fruit oil at a temperature of not more dan 260°C to produce a refined, palm fttft oil.

2. The process according to daim 1, wherein the FFB are washed wim water having a temperatuie range of 30 to 90°G

3. The process according to chum 1, wherein the FFB are washed with biologically treated discharge water having a total alkalinity of 1,000-10,000 mg calcium carbonate (CaCCb) per litre.

4. The process according to cbam 1, wherein the FFB are washed with water for 1 - 30 minutes.

5. The process accenting to claim 1, wherein the FFB are washed by spraying them with water or by submerging them in a water bam.

6. The process according to claim 1, wherein the degumming step is conducted at a . temperature range of 60°C to 120°C.

7. The process according to claim 1, wherein use ritgummmg uses organic acid or mineral acid or any combination thereof in a dosage range of 0.01 to 0.12%.

8. The method according to claim 7, wherein the mineral acid is a phosphoric acid with concentration in the range of 80 to 95% and the organic acid is a citric acid with concentration in the range of 30 to 50%.

9. The method according to claim 1, wherein the bleaching step is conducted at a temperature in the range of 85 to 130°C for 10 to 90 minutes;

10. The method according to claim 1, wherein the bleaching step uses bleaching adsorbent in the amount of between 0.5 to 3% by weight of the degummed palm fruit oil;

11. The method according to claim 10, wherein the bleaching adsorbent is selected from bentonite clay, palygorskite clay, montmorillonite clay, smectite clay or any combination thereof.

12. The method according to claim 1 1 , wherein the bleaching adsorbent is a natural Inactive clay, acid activated bleaching clay, thermal activated bleaching clay or any combination thereof.

13. The method according to claim 1 , wherein the crude palm fruit oil obtained from step (b) contains 0.5 to 1.5% free fatty acids.

14. The process according to claim 1 , wherein the total chlorine content of the crude palm fruit oil of step b) is in the range of 0 to 5 ppm.

15. The process according to claim 1 , wherein total chlorine content of the bleached palm fruit oil of step d) is in the range of 0 to 3 ppm.

16. The process according to claim 1 , wherein 3-MCPD content of the refined palm fruit oil of step e) is in the range of 0 to 1.5 ppm.

17. The process according to claim 1, wherein the crude palm fruit oil is selected from crude palm oil, crude palm oil fraction and combinations thereof.
