Definitions
- the invention relates to a process for bleaching oils and fats.
- 6,346,286 B1 describes a bleaching process in which the oil to be bleached is brought into contact with a particulate composition which comprises particles of a clay mineral and particles of at least one organic acid, the organic acid being substantially free of salts of the organic acid.
- a particulate composition which comprises particles of a clay mineral and particles of at least one organic acid, the organic acid being substantially free of salts of the organic acid.
- citric acid is mentioned as a suitable organic acid.
- FIG. 2 shows a diagram in which the process steps which are carried out during the physical refining of palm oil according to the method according to the invention are reproduced schematically;
- Fig. 8 is a graph showing Lovibond color numbers red and yellow after bleaching with a HUB and deodorizing palm oil for various process operations;
- the Lovibond color numbers are shown in red and yellow, which are obtained using a SMBE (EX 1221 (II)) after bleaching and deodorizing.
- the Lovibond color number yellow follows the trend of the Lovibond color number red.
- a lovibond yellow color of 46 is obtained in the prior art process (Process 3A). Gumming without unlocking and only a vacuum bleaching at 95 0 C (process control 3A.2) a Lovibond is already yellow reaches of the 39th Cutting away the bleaching temperature to 45 0 C. (Method guide 3B.2), a Lovibond yellow is obtained from 35th Wet bleaching at 95 ° C (Procedure 3A.1) achieves a Lovibond yellow color of 39.
