Document Type and Number:
WIPO Patent Application WO/2023/108366
Kind Code:
A1
Abstract:
The method for delaying clouding of an oil comprising palm oil and/or a palm oil derivative. The method includes: providing the oil comprising palm oil and/or a palm derivative; providing a mineral adsorbent, wherein the mineral adsorbent is white clay; adding, to the oil, equal to or greater than about 0.6wt% and less than about 1.0wt% the mineral adsorbent, by weight of the oil; bleaching the oil in the presence of the mineral adsorbent at from about 100 ℃ to about 110 ℃ for about 30-50 minutes at a pressure of about less than about 100 mbar; removing the mineral adsorbent from the bleached oil; deodorizing the bleached oil at from about 220 ℃ to about 245 ℃ for from about 25 to about 45 minutes at a pressure of about less than 10 mbar, wherein the deodorized oil has a color of between Y13R1.3 and Y35R3.5 by Lovibond TM Colorimeter with a cuvette unit size of 133.4 mm.
