Abstract
A process for continuously refining lightcoloured lipoid B-containing crude glyceride oil comprises (a) continuously adding a mixture of aqueous sodium carbonate and sodium hydroxide solutions to a stream of the crude oil, the sodium carbonate solution being added in an amount which is sufficient to prevent any evolution of carbon dioxide gas and which is greater than 2 molar equivalents for each mole of free fatty acid present in the crude oil, and the sodium hydroxide solution being added in an amount which is sufficient to reduce the phosphatide content (calculated as phosphorus pentoxide) of the refined oil to between 3-30 parts per million, (b) subjecting the mixture to shearing forces equivalent to turbine tip speeds of at least 850 feet per minute, preferably at least 1500 feet per minute, for at least 15 seconds, (c) allowing the combination to stand, and/or to be subjected to shearing forces for a time such that the total time of steps (b) and (c) is at least 1 minute, and (d) separating refined oil by centrifuging the resulting mixture. It is preferred that the amount of sodium carbonate be within the range 3-5 molar equivalents for each mole of free fatty acid present in the crude oil and that the solution has a concentration of 16-28 B<\>e; the sodium hydroxide used generally comprises 0.0004-0.004 times the weight of the crude oil, and is generally employed as a solution having a concentration of at least 16 B<\>e, preferably 18-30 B<\>e, the amount of hydroxide used being sufficient to reduce the phosphatide content of the refined oil (calculated as phosphorus pentoxide) to 5-25 parts per million. The weight of sodium hydroxide added per unit weight of the crude oil may be in the range 1/2 W to 1 1/2 W, where W = 0.0935 A + 0.00063, and A = weight of acetone insolubles per unit weight of oil. Where the crude oil has not been degummed, steps (b) and (c) are performed at 70-120 DEG F., preferably 80-90 DEG F.; where the oil has been degummed, temperatures of 100-160 DEG F., preferably 130-140 DEG F., are used. The centrifugal separation step (d) is generally carried out at a temperature of 120-160 DEG F., preferably 130-140 DEG F.
