Method for reducing cholesterol in oils or fats
A process of reducing the cholesterol content in cholesterol-containing organic oils or fats, particularly animal oils or fats. The process comprises the steps of: adding at least one of demineralized water and distilled water having a set pH-value to the oil cholesterol containing oils or fats, thereby forming a mixture; and separating the mixture into a cholesterol-containing aqueous phase and a cholesterol-reduced oil or fat phase.
1. A process of reducing the cholesterol content in cholesterol-containing beef drippings, the process comprising the steps of:
adding only at least one of demineralized water and distilled water having a set pH-value between 4 and 8 to the cholesterol-containing beef drippings, thereby forming a mixture; and
separating the mixture into a cholesterol-containing aqueous phase and a cholesterol-reduced oil or fat phase within a time period of less than 10 minutes.
2. The process according to claim 1 , wherein the separating into the cholesterol-containing aqueous phase takes place in a centrifuge.
3. The process according to claim 1 , wherein the separating into the cholesterol-containing aqueous phase takes place in a separating centrifuge.
4. The process according to claim 1 , wherein the separating takes place within a time period of less than 5 minutes after the adding of the at least one of demineralized water and distilled water.
5. The process according to claim 1 , wherein the steps of adding and separating are repeated at least once.
6. The process according to claim 1 , wherein the at least only one of demineralized water and distilled water is added to the cholesterol-containing oils or fats at a ratio of 1:1.
7. The process according to claim 1 , wherein the separating into the cholesterol-containing aqueous phase takes place in a separator.
8. The process according to claim 7 , wherein the separator includes a vertical axis of rotation and a disk stack.
9. The process according to claim 1 , wherein the separating takes place within a period of less than 120 seconds after the adding of only the at least one of demineralized water and distilled water.
10. The process according to claim 1 , wherein the separating takes place within a time period of less than 60 seconds after the adding of only the at least one of demineralized water and distilled water.
11. A process of reducing the cholesterol content in cholesterol-containing beef drippings, the process comprising the steps of:
adding only at least one of demineralized water and distilled water having a set pH-value between 4 and 6 to the cholesterol-containing beef drippings, thereby forming a mixture; and
separating the mixture into a cholesterol-containing aqueous phase and a cholesterol-reduced oil or fat phase.
12. The process according to claim 11 , wherein the separating takes place within a period of less than 120 seconds after the adding of only the at least one of demineralized water and distilled water.
13. The process according to claim 11 , wherein the separating takes place within a time period of less than 60 seconds after the adding of only the at least one of demineralized water and distilled water.
