Description
Technical Field
The present invention regards the handling of creatures living in a body of water, such as saltwater or freshwater. In particular, the present invention regards the processing of fish and crustaceans. More particularly, the present invention regards stabilizing stickwater deriving from onboard handling and preservation of saltwater fish and crustaceans.
Background Art
Although the method of the present invention may be used to treat stickwater deriving from a wide variety of species living in a body of water, such as saltwater or freshwater, the invention will be described primarily using krill fishing as an example.
Commercial fishing of krill, a small shrimp-like pelagic crustacean swimming in large swarms, is a relative new enterprise in the history of fishing, wherein harvesting large quantities of krill began somewhat recently in the early 1970s. Krill is considered to have one of the largest biomasses of wild multicellular organisms on Earth, of which Antarctic krill (Euphausia superba), a krill subspecies, is currently estimated to have a biomass of approximately 379 million metric tons.
The nutritional composition of krill can comprise up to 60% proteins and up to 25% lipids. The shells of this crustacean primarily consist of chitin, which can be approximately 2% of the krill’s dry weight. The said nutritional composition of krill is therefore one of the main factors for the crustacean’s popularity as feed for both human- and animal consumption and other applications.
However, current harvesting and processing methods are arguably not the most efficient in making use of most of the caught krill. A part of the krill that have not been given much attention to in krill fishing is stickwater, a protein rich liquid, which may exude from the said crustacean during harvesting and processing. However, stickwater does not only derive from krill, but from most creatures like other crustaceans and fish.
In the case of krill, stickwater exudes from the krill if enough pressure is applied on the krill, such as during onboarding a krill catch’s own dead weight may crush the krill in the bottom of the net or storage compartment, pushing the stickwater liquid out of the crushed krill. The stickwater accumulates on deck or in said compartment, and is being mostly left unused and rinsed away in preparation for receiving the next krill batch.
A lion’s share of krill-related inventions does not give much attention to stickwater, which is often disregarded as a byproduct not receiving much importance for preservation, but is generally disposed of as waste. As a result, the prior art is mainly concerning the harvesting and processing of the krill itself.
CN107801764A and CN103503970A are Chinese patents concerning preservation methods of krill that includes providing additives into the krill meat prior freezing. The krill is washed prior to providing the additives, thus washing away the stickwater. CN111480684A is a method that comprise rinsing krill and freezing krill in a block of sea water, wherein the individual krill are separated from each other. Another method, CN105454403B, grinds up raw krill to form a krill mass, whereupon the krill mass is provided with water and additives prior to dehydration of the said mass, before providing further additives and the freezing with the intention to reduce the fluoride content in the krill mass.
EP1015 319B1 is a preservation method for animal protein, wherein stickwater from both fish and crustaceans are explicitly mentioned. In this process stickwater is accumulated and undergoes a heat treatment by pasteurization and sterilization process in preparation for storage.
WO2021/156407A1 describes a process for treatment of krill to produce oil. The krill is harvested, heated, boiled an separated stickwater and solid phase and stickwater is separated in a decanter or separated as solid phase, stickwater and oil in a trichanter. Contrary to the method according to present invention, the process is performed under heated conditions.
US 3586515A relates to a method for the production of fish meal and fish oil. Also this method uses heating to produce the wanted products.
NO 151269B relates to a method for producing fish meal by heating a fish mixture and separate oil from the heated fish mixture by means of a centrifuge.
However, it is coveted to describe a technical and inventive solution in extracting and stabilizing stickwater in order to preserve an optimal freshness of said stickwater.

Brief Description of Drawings
Certain features and functions of the present invention will be described with reference to the following figures in which not every component may be labeled for the sake of clarity, in which:
Figure 1 illustrates a process flow diagram showing the process from raw creatures to stabilized stickwater in freezer hold.
Detailed Description of the Invention
Figure 1 shows a diagram which illustrates an embodiment of the pertinent parts of the process flow necessary for stabilizing protein rich stickwater from creatures living in a body of water, such as saltwater or freshwater, said creatures comprising fish and crustaceans living in the pelagic and/or demersal zone in saltwater or freshwater, such as ocean or lakes.
The process of the invention will be carried out on board a fishing vessel. The associated equipment is in general standard equipment that is already provided on board a fishing vessel that processes the catch before freezing. However, some modifications to the equipment may be necessary depending on the existing configuration.
Prepared creatures, in the form of mechanically fragmented fish or appropriately sized crustaceans where fragmentation is not required, such as whole raw krill, is provided by a feed system 1 into at least one a solid bowl centrifuge 2, preferably a decanter centrifuge 2, a known separator device, for instance provided by GEA (Decanter Centrifuge | Centrifuges & Separation Equipment (gea.com)) or Flottweg SE (https://www.flottweg.com/product-lines/decanter/ per 20.08.2021).
The decanter centrifuge 2 applies centrifugal force on the prepared creatures to separate it into two phases; solids, comprising of the creature’s scales, bones, shell and meat, and the creature’s fluids, also known as stickwater - a protein rich liquid, wherein the latter is accumulated in at least one first buffer tank 3. Whereas the former, the solids, continue along a separate path for further processing, such as freezing and palletizing, and storage (not shown). The separation of the solids from the stickwater is an essential part early on in the process, which is done in order to avoid contaminating the stickwater with fluorides deriving from the solids. More specifically, in the case of crustaceans, fluorides that may derive for instance from krill shells which comprise of chitin, or at the very least maintain the fluorides deriving from chitin from crustaceans contaminating the stickwater at a negligible amount.
An alternative to the decanter centrifuge 2 is to replace it with a solid bowl centrifuge that provides at least three phases, such as a tricanter centrifuge which applies the same technical principles as with the decanter 2.
Conventionally, a tricanter sentrifuge would, instead providing two phases; a solid and a liquid; provide three phases; a solid, a low-viscosity liquid and a high-viscosity liquid. However, such a three-phase separation will usually require that the feed material, the prepared creatures, is heated before going through the centrifuge. When the feed material is as cold as prescribed in the present invention, the third phase, the liquid with a lower viscosity, will be of a very small amount, hence the two liquid phases are mixed together as a single liquid and continues its path to a separator 5 as with the embodiment using a decanter centrifuge 2. The point here is that if a tricanter centrifuge is already present in the facility on board the boat, this can be used much the same way as a decanter centrifuge.
At this stage of the of process the stickwater contains impurities, small and drifting particles of fish or crustaceans, that could be of a size that may obstruct filtration devices 8 for further refinement of the stickwater. In order to achieve a stickwater that is prepared for said filtration devices 8, said particles are removed from the stickwater through a disc separator 5, a known technology, e.g., in the dairy industry as exemplified by a disc separator from GEA (https://www.gea.com/en/products/centrifuges-separation/centrifugalseparator/clarifier/clarifiers-milk-whey-calcium-phosphate.jsp per 20.08.2021).
Achieving a purified stickwater, or liquid phase, is first achieved wherein the stickwater is provided by a first feed pump 4, directing said stickwater from the first buffer tank 3 for further processing into said at least one disc separator 5, applying per se known disc separation principles to extract two phases from the stickwater; solid phase, consisting of fish or crustacean particles, and said liquid phase.
An alternative to the disc separator 5 for removing the undesired particles from the liquid phase is to use a roto-sieve drum screen, a known technology, in essence a rotating perforated drum wherein the liquid passes through the perforations and particles larger than the perforations are left in the drum.
Another alternative to the disc separator 5 is to use a compact sieve or vibrating screener, a known technology, which is a circular vibrating sieving device wherein the solid particles are pushed towards the edges of the sieve and the liquid phase gathers and passes through the sieve in the center of the sieve.
The liquid phase, which also contains high levels of protein, is then accumulated in at least one second buffer tank 6, whereas the other phase, the solids, continue a separate path for further processing, such as thermoforming, freezing and palletizing, and storage (not shown).
A second feed pump 7 directs the liquid phase from the second buffer tank 6 towards at least one ultra-filtration device 8, applying known membrane filtration technology, which is arranged to further refine the liquid phase into an liquid phase concentrate which is accumulated in at least one third buffer tank 9. Excess liquids from the ultra-filtration device 8, liquids that are not a liquid phase concentrate which primarily comprise of saline water, is further disposed of (not shown).
A third feed pump 10 directs the liquid phase concentrate from the third buffer tank 9 for portioning and packaging, wherein the liquid phase concentrate is stored in air-tight packaging material, such as polymer based materials, where the air has also been substantially removed, suitable to be placed in a freezer 12 to achieve a stabilized state and a freezer hold 14 for storage. A preferred manner for portioning and packaging is to use a thermoformer 11, a known technology.
The prepared creatures, stickwater, liquid phase and liquid phase concentrate maintains a specified processing temperature prior on being transferred into a freezer 12, the specified processing temperature does not go higher than 50 degrees Celsius, preferably not higher than 20 degrees, and more preferably as cold as possible, with the intention to maintain optimal freshness of the final product when it achieves its stabilized state, the frozen liquid phase concentrate. Such specified temperature is essential in order to prevent autolysis, decomposing and spoilage, of the creatures and its stickwater which occurs at higher temperatures. It has been found that around 50 degrees Celsius these processes will accelerate.
Solid bowl centrifuges 2, separators 5, ultra-filtration devices 8 and buffer tanks 3, 6, 9 can also be modified to include indirect cooling, consisting cooling by seawater, in order to maintain specified temperature of the creatures, stickwater, liquid phase and liquid phase concentrate located within said equipment.
The processing time for the aforementioned stabilizing process, from the saltwater creatures is brought on board the vessel to placing the liquid phase concentrate in the freezer hold 14, is within the range of 10 min to 60 min, preferably within the range of 10 to 30 min. It is essential to maintain a short processing time to reduce the likelihood of fluoride contamination and autolysis in occurring in the saltwater creatures and stickwater.
To process bycatch according to the present invention, the bycatch may be grinded before it is fed to the first separation stage.
