PACKAGED OXIDATION-STABLE OIL-IN-WATER EMULSION

摘要

One aspect of the invention relates to a packaged, oxidation-stable oil-in-water emulsion comprising: - 0.1-10 wt .% of oil, said oil containing 0.3-80 g of polyunsaturated fatty acids per liter of emulsion; - at least 1 mg/1 of pro-oxidative metal cations; - 10-2000 mg/1 of vitamin C; and - up to 98 wt .% of water; wherein the container comprising the emulsion holds no headspace and wherein the molar ratio of vitamin C to pro- oxidative metal cations exceeds 1:2. Oxidation of the polyunsaturated fatty acids contained in the emulsion, is effectively prevented, despite the fact that the emulsion contain appreciable amounts of pro-oxidative metal cations and even if the emulsion is produced under conditions in which it is in direct contact with air. Another aspect of the invention relates to a method of preparing a packaged emulsion as defined above.
