METHODS FOR PROCESSING VEGETABLE OILS AND VEGETABLE OIL COMPOSITIONS
A method for processing natural oil is provided. The method includes providing a natural oil to be processed, adding an inorganic particulate material to said natural oil, and processing the resulting mixture to obtain oil products with an improved yield and/or quality.
1 . A vegetable oil composition comprising a solid fraction, said solid fraction comprising from about 0.001 % to less than 1 % w/w of the total weight of the composition of an inorganic particulate material, wherein the inorganic particulate material is selected from the group consisting of talc, calcium carbonate, and kaolin.
2 . The vegetable oil composition of claim 1 , wherein the solid fraction is crystallised in the beta prime conformation.
3 . A method for processing a vegetable oil comprising a step of adding an inorganic particulate material to the oil, wherein the amount of inorganic particulate material added is from about 0.001% to less than 1% by weight of the starting oil, wherein the inorganic particulate material is selected from the group consisting of talc, calcium carbonate, and kaolin.
4 . (canceled)
5 . The method of claim 3 , wherein the inorganic particulate material has a d 50 of from about 0.5 to about 30 μm.
6 . The method of claim 3 , wherein the inorganic particulate material is a food additive grade talc.
7 . The method of claim 3 , wherein the cycle time of the processing method is reduced by at least 6% by comparison with the cycle time of the same processing method, but in the absence of any inorganic particulate material.
8 . The method of claim 3 , wherein the iodine value of the low iodine value fraction obtained by said method is lower than the iodine value of the tow iodine value fraction obtained by the same processing method but in the absence of any inorganic particulate material.
9 . An oil product obtained by the method of claim 3 .
10 . The method of claim 7 , wherein the inorganic particulate material acts as an adjuvant in the processing of a vegetable oil.
11 . The vegetable oil composition of claim 1 , wherein the inorganic particulate material has a d 50 of from about 0.5 to about 30 μm.
12 . The vegetable oil composition of claim 11 , wherein the inorganic particulate material is a food additive grade talc.
13 . The vegetable oil composition of claim 11 , wherein the inorganic particulate material is a macrocrystalline tab.
14 . The vegetable oil composition of claim 11 , wherein the inorganic particulate material is a microcrystalline talc.
15 . The vegetable oil composition of claim 11 , wherein the inorganic particulate material is a chloritic talc.
16 . The method of claim 3 , wherein the inorganic particulate material is a microcrystalline talc.
17 . The method of claim 3 , wherein the inorganic particulate material is a microcrystalline talc.
18 . The method of claim 3 , wherein the inorganic particulate material is a chloritic talc.
