Definitions

  • the present invention relates to a method for ex- tracting oil from fish offal, comprising the step of heating the offal to a temperature above +30°C while keeping the offal in a liquid-permeable container from which oil extracted from the offal by heating is sepa ⁇ rated by dripping off, the rest of the offal remaining in the container.
  • the invention aims at providing an easily practicable method for extraction, which allows cost-effective use of fish offal while yielding high-quality oil.
  • This object is achieved by a method which is characterised in that the fish offal in an initial step, before being heated to the temperature stated by way of introduction, is deep-frozen, i.e. frozen to a temperature below -18°C, and thereafter thawed from the deep-frozen state.
  • the deep ⁇ freezing temperature is kept between -20°C and -30°C.
  • the fish offal is stored in its deep-frozen state, preferably for at least one day, and suitably for a longer period, e.g. 2-4 days. Then, the material is placed in an environment having a temperature of above +5°C so as to thaw, whereupon it is heated to a temperature exceeding +30°C, preferably a temperature of between +40°C and +50°C, at which it is kept for at least one hour. Advan- tageously, this heating can be carried out at such a rate that the temperature increases by about 5-30°C/hour.
  • the fish offal is kept in a first, liquid-permeable container, for example a string bag con ⁇ sisting of a fine-meshed net or a vessel with a straining cloth, which itself is disposed inside or above a second, liquid-impermeable container.
  • a fat-containing liquid in the form of oil will gradually be extracted from the heated material and allowed to drip off from the first, liquid-permeable container into the second container for collection of the liquid.
  • the amount of oil or oily liquid obtained by the method may be up to 70-80% of the weight of the fish offal in solid form.
  • the resulting oil has low viscosity (about the same viscosity as sewing-machine oil) and high storage _l stability, so that its properties will not change. If 5 blood-containing matter, such as heart and liver, are removed from the starting material, i.e. the fish offal, the resulting oil will be clear and of a pale yellow, but with an increasing amount of blood-containing matter in the offal, the red-colouring of the oil is intensified.
  • the resulting oil contains many useful substances, such as unsaturated fatty acids, for which reason it can be used in a number of technical fields, e.g. as raw mate ⁇ rial for the production of foodstuffs, medicines, cosme ⁇ tics, lubricants and fuels.

Abstract

Le procédé décrit, qui sert à extraire de l'huile de viscères de poissons, consiste à chauffer les viscères à une température supérieure à +30°C, tout en les maintenant dans un récipient perméable au liquide, dans lequel l'huile extraite des viscères par chauffage est séparée par égouttage, le reste des viscères restant dans le récipient. Dans une étape initiale et avant d'être chauffés à la température mentionnée ci-dessus, les viscères sont surgelés, c'est-à-dire congelés à une température inférieure à -18°C, avant d'être dégelés de leur état surgelé.
