  • Deodorizing edible oil and/or with non-condensible inert gas and recovering a high quality fatty acid distillate
    Patent number: 5374751
    Abstract: The invention relates to a process for deodorizing edible oils and/or fats comprising: heating edible oil and/or fat to an elevated temperature; introducing or injecting non-condensible inert gas into said edible oil and/or fat to strip or remove substances that impart disagreeable odor and taste to said edible oil and/or fat; and recovering the resulting deodorized edible oil and/or fat, wherein an amount of said non-condensible inert gas introduced or injected is substantially less than the theoretically required amount for deodorizing said edible oil and/or fat. The condensible gas may be preheated before its introduction into the edible oil and/or fat.
