Abstract
A process for stabilizing fully or partially refined marine oil is disclosed. Here marine oil is treated with silica having a surface area greater than 500 m.sup.2 per gram. Then the silica treated oil is soft vacuum steam deodorized at a temperature between 140.degree. C. and about 210.degree. C. Finally the oil is treated with a combination of lecithin, ascorbyl palmitate and tocopherol in ratios of 6-3:4-2:8-4 the range of 1000 parts per million to 4000 parts per million.
