Abstract
Processes are described for refining a renewable oil. The processes may include the steps of adding one or more compounds to the renewable oil to produce a soap stock in the renewable oil, and separating at least a portion of the soap stock from the renewable oil. The processes may further include adding a polymer to the separated renewable oil to produce a refined renewable oil.
Claims21
A process of refining a renewable oil, the process comprising:
- adding one or more compounds to the renewable oil to produce a soap stock in the renewable oil;
- separating at least a portion of the soap stock from the renewable oil;
- and
- adding a polymer to the separated renewable oil to produce a refined renewable oil.
A process for refining a renewable oil, the process comprising:
- removing a first portion of free fatty acids from a starting renewable oil to produce a partially refined oil;
- and
- removing a second portion of free fatty acids from the partially refined oil to produce a refined renewable oil, wherein the removal of the second portion of free fatty acids comprises adding a polymer to the partially refined oil.
A process of refining a renewable oil with an edible polymer, the process comprising:
- adding the edible polymer to the renewable oil, wherein the edible polymer comprises a powder phase;
- and
- binding at least a portion of free fatty acids in the renewable oil to the edible polymer.
