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.
Claims18
A process for maintaining the storage stability of an oil during shipment or storage, the process comprising
- storing an oil in a container at a temperature ranging from about 4° C. to about 45° C. for at least one month, wherein either (i) the oil has an anisidine value of less than 3 after storage;
- or (ii) the absolute change in the anisidine value of the oil during storage is no more than about 20;
- and wherein the process for preparing the oil comprises
- degumming a crude oil under an inert atmosphere to form a degummed oil;
- contacting the degummed oil with a bleaching material under process conditions that minimize oxidation to form a bleached oil;
- and
- deodorizing the bleached oil in a continuous deodorizer at a temperature from 220° C. to 255° C. at a pressure of less than about 1.4 kPa and a residence time of up to 30 minutes to form the oil composition having an anisidine value of less than about 3.
A process for maintaining the storage stability of an oil during shipment or storage, the process comprising storing an oil in a container;
- and freezing the container;
- wherein the process for preparing the oil comprises
- degumming a crude oil under an inert atmosphere to form a degummed oil;
- contacting the degummed oil with a bleaching material under process conditions that minimize oxidation to form a bleached oil;
- and
- deodorizing the bleached oil in a continuous deodorizer at a temperature from 220° C. to 255° C. at a pressure of less than about 1.4 kPa and a residence time of up to 30 minutes to form the oil composition having an anisidine value of less than about 3.
A process for maintaining the storage stability of an oil during shipment or storage, the process comprising encapsulating the oil in an encapsulation material;
- wherein the process for preparing the oil comprises
- degumming a crude oil under an inert atmosphere to form a degummed oil;
- contacting the degummed oil with a bleaching material under process conditions that minimize oxidation to form a bleached oil;
- and
- deodorizing the bleached oil in a continuous deodorizer at a temperature from 220° C. to 255° C. at a pressure of less than about 1.4 kPa and a residence time of up to 30 minutes to form the oil composition having an anisidine value of less than about 3.
