Description

Den foreliggende oppfinnelse vedrører en fremgangsmåte til The present invention relates to another method

utvinning av fett/olje fra fet fisk. extraction of fat/oil from oily fish.

Ifølge kjent teknikk utvinnes oljen av fisk ved varmebe-handling og pressing av oppmalt fisk (fiskemasse). Det oppnås derved én oljefraksjon som inneholder olje fra de forskjellige deler av fisken. According to known techniques, the oil is extracted from fish by heat treatment and pressing of ground fish (fish pulp). This results in one oil fraction containing oil from the different parts of the fish.

Imidlertid har oljen/fettet varierende sammensetning, av-hengig av hvor oljen/fette befinner seg i fisken, f.eks. i fiske-kjattet respektivt innvollene. For enkelte anvendelser må det derfor utføres fysisk skilling av fiskekjøtt og innvoller eller etterfølgende separering av oljen, noe som kan være både kompli-sert og kostbart. However, the oil/fat has a varying composition, depending on where the oil/fat is located in the fish, e.g. in the fish meat or the entrails. For some applications, physical separation of fish meat and viscera or subsequent separation of the oil must therefore be carried out, which can be both complicated and expensive.

Formålet med den foreliggende oppfinnelse er å frembringe en fremgangsmåte som allerede ved utvinningen av oljen gir en viss separering. The purpose of the present invention is to produce a method which already during the extraction of the oil provides a certain separation.

Dette oppnås ifølge oppfinnelsen ved at This is achieved according to the invention by

a) at fisken oppbevares hel i varmt vann inntil den har oppnådd en temperatur på 40-100°C, hvorved en første fraksjon a) that the fish is kept whole in hot water until it has reached a temperature of 40-100°C, whereby a first fraction

olje utskilles av fisken og separeres fra det varme vann, og oil is secreted by the fish and separated from the hot water, and

b) at den varme, hele fisk uttas av vannet og presses på i og for seg kjent måte, hvorved det dannes oljeholdig pressvæske b) that the hot, whole fish is taken out of the water and pressed in a manner known per se, whereby an oily pressing liquid is formed

hvorfra det separeres en andre fraksjon olje. from which a second fraction of oil is separated.

Det arbeides ved temperaturer på minst 40°C for at enzymer i fisken skal bli inaktivert. Fortrinnsvis utføres fremgangsmåten ved over 60°C på grunn av at det meste av det vannbindende protein koagulerer ved slike temperaturer. We work at temperatures of at least 40°C so that enzymes in the fish are inactivated. Preferably, the method is carried out at above 60°C due to the fact that most of the water-binding protein coagulates at such temperatures.

Ved oppbevaringen i det varme vann kommer den utskilte olje hovedsakelig fra fiskekjøttet (muskelen), mens den andre oljefraksjon, som altså utvinnes fra pressvæsken, inneholder restolje fra fiskekjøttet, samt olje fra innvoller og tarminnhold. During storage in the hot water, the secreted oil comes mainly from the fish meat (muscle), while the other oil fraction, which is thus extracted from the press liquid, contains residual oil from the fish meat, as well as oil from viscera and intestinal contents.

Den første fraksjon har en blekere farge enn den andre fraksjon, noe som skyldes at fettløselige fargestoffer fra tarm-innholdet og innvollene først frigjøres i den andre fraksjon. The first fraction has a paler color than the second fraction, which is due to the fact that fat-soluble dyes from the intestinal contents and viscera are first released in the second fraction.

Innholdet av uforsåpbare bestanddeler er lavest i den første fraksjon, og forskjellen kan være stor, noe som vil fremgå av et av eksemplene nedenfor. The content of unsaponifiable components is lowest in the first fraction, and the difference can be large, as will be seen from one of the examples below.

I lodde og sild er opptil 40 vekt% av fiskens fett blitt utskilt i den første fraksjon. In capelin and herring, up to 40% by weight of the fish's fat has been secreted in the first fraction.

Ved fremgangsmåten ifølge oppfinnelsen er det mulig å frak-sjonere fett/olje i fisk på en relativ enkel måte og derved ut-nytte den spesielle sammensetning av hver fraksjon på en bedre måte enn tidligere, hvor man oppnådde én fraksjon. Forutsetningen er at det anvendes fet fisk da det er slik fisk som har fett i fiskekjøttet. With the method according to the invention, it is possible to fractionate fat/oil in fish in a relatively simple way and thereby utilize the special composition of each fraction in a better way than previously, where one fraction was obtained. The prerequisite is that oily fish is used, as it is such fish that has fat in the fish meat.

Eksempel 1 Example 1

100 kg åtefri sild ble oppbevart i ca. 250 1 vann i en beholder, ved en temperatur på ca. 90°C i ca. 0,30 timer. Deretter ble den varme sild, som veide 90 kg, tatt ut av beholderen, fra det gjenværende vann ble det i en separator utskilt 7 kg olje, som en første fraksjon. Denne olje var svakt gul på farge. 100 kg of feed-free herring were stored for approx. 250 1 water in a container, at a temperature of approx. 90°C for approx. 0.30 hours. Then the hot herring, which weighed 90 kg, was taken out of the container, from the remaining water 7 kg of oil was separated in a separator, as a first fraction. This oil was slightly yellow in colour.

Den uttatte sild ble anbrakt i en presse, hvorved det fra den dannede pressvæske ble utvunnet 18 kg olje, som en andre fraksjon. Denne olje var gul på farge. The removed herring was placed in a press, whereby 18 kg of oil was extracted from the formed press liquid, as a second fraction. This oil was yellow in colour.

Eksempel 2 Example 2

100 kg åteholdig lodde ble oppbevart i ca. 250 1 varmt vann ved en temperatur på ca. 80°C i ca. 0,30 timer i en beholder. Deretter ble lodda, som veide 56 kg, tatt ut av beholderen. Fra vannet ble det i en separator utskilt ca. 6 kg olje, som en første fraksjon. Denne fraksjon hadde en sterk gulfarge. 100 kg of edible capelin was stored for approx. 250 1 hot water at a temperature of approx. 80°C for approx. 0.30 hours in a container. Then the capelin, which weighed 56 kg, was taken out of the container. From the water, approx. 6 kg of oil, as a first fraction. This fraction had a strong yellow color.

Den uttatte lodde ble anbrakt i en presse, og fra den dannede pressvæske ble det utvunnet ca. 8 kg olje, som en andre fraksjon. Denne olje var orange på grunn av innhold av farge-stoffet astaxantin. The extracted solder was placed in a press, and approx. 8 kg of oil, as a second fraction. This oil was orange due to the content of the coloring substance astaxanthin.

Resultater: Results:

Som det fremgår av eksempel 2 ovenfor er ca. 40% av oljen i den første fraksjon. As can be seen from example 2 above, approx. 40% of the oil in the first fraction.

Ved fremgangsmåten ifølge oppfinnelsen anvendes det hel fisk. Dette er helt vesentlig. En sløyeoperasjon vil kunne til-føre fiskemuskelen enzymer (lipaser, proteaser) fra innvollene, noe^som kan forringe fettets kvalitet. Sløying/filetering blir også kostbart og kapasitetsbegrensende, spesielt for lodde. Dess-uten vil en slik operasjon redusere utbyttet med tanke på sub-kutant fett. In the method according to the invention, whole fish is used. This is absolutely essential. A gutting operation will be able to add enzymes (lipases, proteases) from the viscera to the fish muscle, which can reduce the quality of the fat. Gutting/filleting also becomes costly and capacity-limiting, especially for capelin. In addition, such an operation will reduce the yield in terms of subcutaneous fat.

På grunn av oljens stabilitet synes lodde særlig aktuell for fremgangsmåten. Men også sild, tobbis og annen fet fisk kan benyttes. Due to the oil's stability, solder seems particularly relevant for the method. But herring, flounder and other fatty fish can also be used.
