Abstract

The present invention is directed to processes for preparing oil compositions having a high concentration of poly-unsaturated fatty acids and oil compositions having a low concentration of α-linolenic acid. In addition, the present invention is directed to processes for preparing oil compositions having advantageous stability characteristics.

Claims

1-119. -119. (canceled)

120. 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.

121. The method of claim 120 comprising 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.

122. The method of claim 120 comprising 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.

123. The method of claim 120 comprising 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.

124. The process of claim 120 further comprising the step of reacting the degummed oil with an acidic aqueous solution before the degummed oil is contacted with the bleaching material to form the bleached oil.

125. The process of claim 120 wherein the inert gas is selected from nitrogen, helium, neon, argon, krypton, xenon, carbon dioxide, carbon monoxide, hydrogen cyanide, or a mixture thereof.

126. The process of claim 125 wherein the inert gas is nitrogen.

127. The process of claim 120 wherein the degummed oil was bleached at a temperature from about 95°

C. to about 110°

C. at a pressure of about 2.5 to 4.0 kPa.

128. The process of claim 120 wherein the degummed oil and the bleaching material was purged of oxygen before the bleaching step.

129. The process of claim 120 wherein the bleached oil was deodorized in the presence of an inert gas.

130. The process of claim 120 further comprising the step of storing the seed meats, the seed hulls or the oil-containing material in the presence of an inert gas.

131. The process of claim 123 wherein concentration of transition metals is minimized and at least one stabilizer is added to the seed meats or oil in one or more steps of the process.

132. The process of claim 123 wherein exposure of the seeds, seed meats, seed hulls, or oil to light is minimized in one or more steps of the process.

133. The process of claim 120 wherein the oil composition has peroxide value of less than 1.0 meq/kg.

134. The process of claim 120 wherein the crude oil has a peroxide value of 0 meq/kg.

135. The process of claim 120 wherein the oil is algal, almond, avocado, babassu, borage, blackcurrant seed, canola, castor bean, coconut, corn, cottonseed, Echium, evening primrose, flax seed, gooseberry, grapeseed, groundnut, hazelnut, linseed, mustard, olive, palm, palm kernel, peanut, pine seed, poppy seed, pumpkin seed, rapeseed, redcurrant, rice bran, safflower, sesame seed, soybean, sunflower, tea, walnut, or wheat germ oil.

136. The process of claim 120 wherein the oil comprises a plant oil.

137. The process of claim 136 wherein the plant oil is from Arabidopsis, canola, carrot, coconut, corn, cotton, flax, linseed, maize, palm kernel, peanut, potato, rapeseed, safflower, soybean, sunflower, tobacco, and mixtures thereof.

138. The process of claim 137 wherein the plant oil is from soybean.
