Abstract
A method for the production of deodorized glycerides from fatty acids containing odor bodies. The method comprises: (a) adding glycerine to the fatty acids to form a first mixture; (b) mixing the first mixture; (c) heating the first mixture at a temperature of from 120° C. to 250° C. to form a heated mixture; (d) removing water and odor bodies from the heated mixture; (e) optionally checking the amount of fatty acids remaining in the heated mixture; (f) optionally removing residual odor bodies from the heated mixture; and (g) recovering the deodorized glycerides.
Claims13
A method for the production of deodorized glycerides from fatty acids containing odor bodies, said method comprising:
- (a) adding glycerine to the fatty acids to form a first mixture;
- (b) mixing said first mixture;
- (c) heating said first mixture at a temperature of from 120° C. to 250° C. to form a heated mixture.
- (d) removing water and odor bodies from said heated mixture by a means selected from the group consisting of:
- (1) reducing the pressure of the heated mixture;
- (2) sparging the heated mixture with inert gas;
- and
- (3) combinations thereof;
- (e) optionally checking the amount of fatty acids remaining in said heated mixture;
- (f) optionally removing residual odor bodies from said heated mixture, wherein removing is selected from the group consisting of:
- (1) sparging the heated mixture with an inert gas;
- (2) steam stripping the heated mixture;
- (3) reducing the pressure of the heated mixture;
- and
- (4) combinations thereof;
- (g) recovering the deodorized glycerides.
The method of claim 11, wherein checking in step (e) comprises confirming that greater than 95% of the fatty acids are no longer present in the heated mixture.
