Title: Process for refining animal and vegetable oil
Inventor: DELMAS MICHEL
IPC: A23K10/00
Filed: 2000-01-05
Abstract: The present invention provides for a process for refining animal or vegetable oil. Unprocessed oil is made up of triglycerides and other compounds such as fatty acids, mono and diglycerides formed by esterification of one or two hydroxy groups of glycerol with an organic acid, phosphoglycerides which contain at least one atom of phosphorus, molecules coming from secondary metabolisms such as steroids, tocopherols, carotenes, and sugars. The process of the present invention comprises treating the unprocessed oil with absorbent silica.
