The production process occurs preferably under an inert gas atmosphere. ## Claims ### Claim 1 A process for the preparation of a marine oil preparation, comprising (a) forming an oil-in-water emulsion comprising at least one marine oil, marine oil concentrate, or mixtures thereof, wherein said marine oil, marine oil concentrate, or mixture thereof comprises a fatty acid consisting essentially of omega-3 polyunsaturated fatty acids, in an amount sufficient to provide a mayonnaise-type emulsion or paste, under an inert atmosphere; and (b) completely filling said oil-in-water emulsion into a container of an airtight material, wherein said container collapses proportionally to the amount of said marine oil preparation remaining after a portion of said marine oil preparation is dispensed, wherein no air space forms in said container after said dispensing, and wherein no discernible oxidation occurs during the storage and use of said marine oil preparation. ### Claim 2 (depends on 1) The process of claim 1, wherein said oil-in-water emulsion comprises 22 to 90% by weight of said marine oil, marine oil concentrate, or mixtures thereof. ### Claim 3 (depends on 2) The process of claim 2, wherein said oil-in-water emulsion comprises 60 to 90% by weight of said marine oil, marine oil concentrate, or mixtures thereof. ### Claim 4 (depends on 3) The process of claim 3, wherein said oil-in-water emulsion comprises 66 to 88% by weight of said marine oil, marine oil concentrate, or mixtures thereof. ### Claim 5 (depends on 1) The process of claim 1, wherein said marine oil is cod-liver oil, and wherein said marine oil concentrate is cod-liver oil concentrate. ### Claim 6 (depends on 1) The process of claim 1, further comprising adding water-soluble vitamins to the aqueous phase of said oil-in-water emulsion prior to said filling step. ### Claim 7 (depends on 1) The process of claim 1, further comprising adding oil-soluble vitamins to the oily phase of said oil-in-water emulsion prior to said filling step. ### Claim 8 (depends on 1) The process of claim 1, wherein said air-tight material is a soft plastic. ### Claim 9 (depends on 1) The process of claim 1, wherein said container is a tube. ### Claim 10 (depends on 1) The process of claim 1, wherein said container comprises a stiff, static container with a piston or screw for dispensing said marine oil preparation. ### Claim 11 (depends on 1, 5) The process of claims 1 or 5, wherein the proportion of polyunsaturated fatty acids in said emulsion is from 19-25% by weight. ### Claim 12 (depends on 1) The process of claim 1, wherein said inert atmosphere is selected from the group consisting of N.sub.2 and CO.sub.2. ### Claim 13 A process for the dispensing of a marine oil preparation, comprising: (a) forming an oil-in-water emulsion comprising at least one marine oil, marine oil concentrate, or mixtures thereof, wherein said marine oil, marine oil concentrate, or mixture thereof comprises a fatty acid consisting essentially of omega-3 polyunsaturated fatty acids, in an amount sufficient to provide a mayonnaise-type emulsion or paste, under an inert atmosphere; (b) completely filling said oil-in-water emulsion into a container of an airtight material to obtain said marine oil preparation; and (c) removing a portion of said marine oil preparation from said container and collapsing said container proportionally to the amount of said marine oil preparation remaining after said portion of said marine oil preparation is removed, wherein no air space forms in said container after said removing, and wherein no discernible oxidation occurs during the storage and use of said marine oil preparation. ### Claim 14 (depends on 13) The process of claim 13, wherein said oil-in-water emulsion comprises 22 to 90% by weight of said marine oil, marine oil concentrate, or mixtures thereof. ### Claim 15 (depends on 14) The process of claim 14, wherein said oil-in-water emulsion comprises 60 to 90% by weight of said marine oil, marine oil concentrate, or mixtures thereof. ### Claim 16 (depends on 15) The process of claim 15, wherein said oil-in-water emulsion comprises 66 to 88% by weight of said marine oil, marine oil concentrate, or mixtures thereof. ### Claim 17 A marine oil product comprising a container formed of an airtight material, and inside said container, a marine oil mayonnaise-type emulsion or paste, comprising an oil-in-water emulsion, wherein said oil is a marine oil, marine oil concentrate, or a mixture thereof, wherein said marine oil, marine oil concentrate, or mixture thereof comprises a fatty acid consisting essentially of omega-3 polyunsaturated fatty acids, and wherein said tube or container is arranged to collapse during use proportionally to the amount of said marine oil mayonnaise-type emulsion or paste remaining after a portion of said marine oil preparation is dispensed from said container, wherein no air space forms in said container after said dispensing, and wherein no discernible oxidation occurs during the storage and use of said marine oil mayonnaise-type emulsion or paste. ### Claim 18 (depends on 17) The product according to claim 17, wherein said air-tight material is a soft plastic. ### Claim 19 (depends on 17) The product according to claim 17, wherein said container is a tube. ### Claim 20 (depends on 17) The product according to claim 17, wherein said container comprises a stiff, static container with a piston or screw for dispensing said marine oil preparation. ### Claim 21 (depends on 17) The product according to claim 17, wherein the aqueous phase of said oil-in-water emulsion further comprises added water-soluble vitamins. ### Claim 22 (depends on 17) The product according to claim 17, wherein the oily phase of said oil-in-water emulsion further comprises added oil-soluble vitamins. ### Claim 23 (depends on 17) The product according to claim 17, wherein said oil-in-water emulsion comprises 22 to 90% by weight of said marine oil, marine oil concentrate, or mixtures thereof. ### Claim 24 (depends on 23) The product according to claim 23, wherein said oil-in-water emulsion comprises 60 to 90% by weight of said marine oil, marine oil concentrate, or mixtures thereof. ### Claim 25 (depends on 24) The product according to claim 24, wherein said oil-in-water emulsion comprises 66 to 88% by weight of said marine oil, marine oil concentrate, or mixtures thereof. ### Claim 26 (depends on 17) The product according to claim 17, wherein the proportion of polyunsaturated fatty acids in said oil-in-water emulsion is from 19 to 25% by weight.
