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.
