Preparation of food-grade marine edible oils by treatment with silica, vacuum steam deodorisation and addition of a herb extract

摘要

Marine oil is stabilized by treatment with silica in the presence or absence of carbon, vacuum steam deodorisation at a temperature between about 140 DEG C and about 210 DEG C in the presence of 0.1-0.4% deodorised rosemary or sage extract. If desired 0.01-0.03% ascorbyl palmitate and 0.05-0.2% mixed tocopherol can be added.
