Definitions

  • the present invention relates to an edible product contai ⁇ ning n-3, n-6 and n-9 unsaturated fatty acids, comprising a marine animal ingredient and an oil-in-water emulsion which product contains at least 1 wt% of C20:5 and C22:6 n-3 polyunsaturated fatty acids, and a process for preparing the product.
  • the group of fatty acids comprises saturated, monounsatura- ted and polyunsaturated fatty acids.
  • the term "unsaturated” indicates that the fatty acid contains at least one double bond between carbon atoms.
  • Fatty acids are generally clas ⁇ sified according to (1) the length of the carbon chain, (2) the number of double bonds and (3) the position of the last double bond in relation to the methyl terminal of the molecule.
  • C18:2 n-6 (linoleic acid) designates a fatty acid with 18 carbon atoms in the chain and comprising two double bonds of which the first from the methyl end of the fatty acid is at the sixth carbon atom.
  • n-3 and n-6 unsaturated fatty acids are dietary essential fatty acids which must be supplied in the diet in amounts which are sufficient to maintain normal body functions.
  • n-3 polyunsaturated fatty acids are one impor ⁇ tant dietary class of polyunsaturated fatty acids of which ⁇ -linolenic acid (C18:3 n-3) is the parent compound.
  • -Li- nolenic acid is present in plant oils such as linseed, rapeseed and soybean oil.
  • marine phytoplankton and zooplankton are rich sources of longer n-3 polyunsaturated fatty acids and are the source of the abundant C20:5 n-3 eicosapentaenoic (EPA) and C22:6 n-3 docosahexanoic (DHA) acids in marine animals.
  • marine animal products are significant dietary sources of lipids containing long chain n-3 polyunsaturated fatty acids, in particular C20:5 n-3 and C22:6 n-3.
  • long chain PUFAs typically constitute 20-30 wt of the total fatty acid content.
  • Polyunsaturated fatty acids of which linoleic acid (C18:2 n-6) is the parent compound are the predominant unsaturated fatty acids in many plant oils including saf- flower oil, corn oil, grape kernel oil, cottonseed oil and sunflower seed oil.
  • Oleic acid (C18:l n-9) is the parent compound for the class of n-9 unsaturated fatty acids which are present in high amounts in animal fat and in certain plant oils/fats such as olive oil and rape seed oil.
  • monounsaturated fatty acids such as oleic acid (C18:l n-9) reduce LDL cholesterol without changing high-density- lipoprotein (HDL) cholesterol.
  • the subsequent reduction of the LDL/HDL cholesterol ratio is associated with a reduced risk for atherosclerosis.
  • Intake of the n-6 polyunsaturated fatty acids also results in a reduction of total cholesterol and LDL cholesterol.
  • PUFAs may contribute to a lower risk for thrombosis.
  • the long-chain polyunsaturated n-3 fatty acids from marine sources reduce serum triglycerides and very-low-density- lipoprotein, two other atherosclerosis risk factors, where ⁇ as the concentration of HDL cholesterol is increased and LDL cholesterol is unchanged or slightly increased.
  • Fur- thermore, blood platelets, endothelial cells, and perhaps other factors involved in thrombus formation may be affec ⁇ ted in an antithrombotic direction by the n-3 long-chain PUFAs.
  • n-3 PUFAs affect the function of the white blood cells resulting in a certain inhibitory effect on the inflamma ⁇ tory response of the body. This effect may be beneficial in humans suffering from chronic polyarthritis or psoriasis. Since processes associated with the inflammatory response are also involved in the forming of atherosclerotic plaqu ⁇ es, n-3 fatty acids may also have an inhibitory effect on such plaque formation. Finally, it has also been found that replacement of saturated fatty acids by unsaturated fatty acids tends to lower the blood pressure.
  • n-3 fatty acid enriched food products do not provide a recommended daily dosage of n-3 PUFAs unless large quanti ⁇ ties of the food products are consumed regularly.
  • n-3 PUFAs One obvious way of providing a high dietary intake of n-3 PUFAs would be to consume high quantities of fatty fish like salmon or mackerel on a daily basis. However, this approach would require a daily consumption of fatty fish in the order of 100-200 g. It is known to prepare products containing fatty fish in a conventional oil-in-water emul- sion dressing or mayonnaise. Examples of such products include herring salads in a mayonnaise-type dressing and cooked mackerel in mayonnaise. Such products may contain n-9 and/or n-6 fatty acids in amounts which are typically in the range of 5-15 g/100 g. However, the content of n-3 PUFAs is in the range of 0.4-0.8 g/100 g.
  • the present invention provides novel edible products con ⁇ taining in a package unit a recommended daily dosage of n-3 polyunsaturated fatty acids and a dietetically effec ⁇ tive amount of n-9 unsaturated fatty acids.
  • the present invention relates to an edible product containing a mixture of n-3, n-6 and n-9 unsaturated fatty acids comprising (a) 10-90 wt% of a marine animal ingredient and (b) 10-90 wt% of an oil-in- water emulsion comprising an oily phase which is in the range of 20-80 wt%, calculated on the emulsion, said edible product having a content of C20:5 and C22:6 n-3 polyunsa ⁇ turated fatty acids which is at least 1 wt%.
  • the product may further comprise 0.1-25 wt% of non-liquid vegetable and/or fruit ingredients and it may conveniently be in the form of portions contained in a package material preferably having a low oxygen penetration coefficient.
  • the invention provides a process for preparing the edible product containing a mixture of n-3, - n-6 and n-9 unsaturated fatty acids and having a content of C20:5/C22:6 n-3 polyunsaturated fatty acids being at least 1 wt%, said process comprising the following steps:
  • step (iv) mixing in an atmosphere of an inert gas the emulsion of step (iii) with a marine animal ingredient, and optio ⁇ nally
  • step (v) adding to the mixture resulting from step (iv) one or more non-liquid vegetable and/or fruit ingredients, to obtain the edible product wherein the proportion of the marine animal product is in the range of 10-90 wt%, the proportion of the oil-in-water emulsion in the range of 20-80 wt% and the proportion of the non-liquid vegetable and/or fruit ingredient, when present being in the range of 0.1-25 wt%, and
  • the edible product according to the invention comprises 10-90 wt% of a marine animal ingredient and 10-90 wt% of an oil-in-water emulsion.
  • the term "marine animal” include any edible aquatic animal such as salt-water fish, fresh water fish, aquatic mammals including whales and seals; shellfish including shelled mollusks such as clams and crustaceans such as lobsters, shrimps, crabs and barnacles; and Cephalopoda spp such as octopus spp and squids.
  • the product according to the invention may contain one marine animal ingredient or a mixture of such ingredients.
  • the marine animal ingredient may conveniently be a cooked ingredient e.g. in the form of tinned products which have been subjected to a pressure cooking process. In such cooked ingredients, the proteins are coagulated as a result of the heat treatment.

  • the marine animal ingredient may also be a raw or pickled ingredient which has been subjected to a smokecuring treatment.

  • a useful fish ingredient may be an ingredient derived from fish selected from the group consisting of anchovy, white fish, dogfish, eel, herring, mackerel, menhaden, sardine, squid, tuna, salmon and trout.
  • Particularly useful fish ingredients are derived from fish species having a high content of long-chained polyunsatura- ted fatty acids including C20:5 and C22:6 n-3 fatty acids. Accordingly, the fish ingredient may advantageously have a content of such n-3 unsaturated fatty acids which is at least 0".5 wt%, preferably at least l.0 wt% and most pre ⁇ ferably at least 1.5 wt%.
  • Examples of fish species having in their flesh such a high content of the C20:5 and C22:6 n-3 polyunsaturated fatty acids include herrings, anchovi ⁇ es, mackerel, menhaden and sardines.
  • roe and the liver of fish even from fish with a low content of the long-chained n-3 fatty acids in the flesh, has a high content of these fatty acids. Accordingly, fish roe such as cod roe and fish liver oil are useful sources of C20:5 and C22:6 n-3 polyunsaturated fatty acids in the products according to the invention.

  • the marine animal ingredient may be distributed substanti ⁇ ally evenly in the oil-in-water emulsion of the product, although it will be understood that an initially evenly distributed ingredient as a result of the gravity of the pieces or particles may tend to become dislocated downward during storage of the product.
  • the extent of this disloca ⁇ tion will i.a. depend on the viscosity of the emulsion.
  • a product in which the storage dislocation of. the marine animal ingredient pieces or particles is con- trolled may be prepared by using an emulsion having a high viscosity.
  • Products in which the marine animal ingredient remains essentially evenly distributed may be prepared by using a finely divided ingredient optionally mixed with an oil-in-water emulsion having a high viscosity.
