Patent ID: 8901299

Claim:
A process for preparing an oil composition comprising degumming a crude oil to form a degummed oil; bleaching the degummed oil to form a bleached oil; deodorizing the bleached oil at a temperature from about 160° C. to about 200° C. at a pressure of not more than about 1.4 kPa for not more than about 130 minutes to form the oil composition having an anisidine value of less than about 3 and comprising less than 1 wt. % trans-fatty acid based on the total weight of fatty acids or derivatives thereof in the oil composition; and further comprising at least one of the following steps: (i) contacting the degummed oil with a bleaching material at a temperature from about 80° C. to about 120° C. at a pressure of about 0.6 to 7 kPa to form the bleached oil; (ii) reacting the crude oil with an acidic aqueous solution, at a temperature of at least 35° C. and in the presence of an inert gas to minimize oxygen concentration, to form the degummed oil; or (iii) cracking and dehulling whole seeds, in the presence of an inert gas to minimize oxygen concentration, to form seed meats or seed hulls, or milling, grinding, or flaking an oil-containing material, in the presence of an inert gas to minimize oxygen concentration, to form oil-containing material having increased surface area, and contacting the seed meats, the seed hulls or the oil-containing material having increased surface area with an extraction fluid to extract a crude oil from the seed meats, the seed hulls or the oil-containing material.
