Fremgangsmåte til fremstilling av et spiselig proteinprodukt av limvann. Process for producing an edible protein product from glue water.
Foreliggende oppfinnelse angår fremstilling av oppløselige spiselige proteinpro-dukter fra det material som er kjent i The present invention relates to the production of soluble edible protein products from the material known in
fiskeindustrien som limvann. Dette material er den væske som blir tilbake etter the fishing industry as glue water. This material is the liquid left behind
fjernelsen av suspenderte faste stoffer og the removal of suspended solids and
oljer fra pressvæske. oils from press fluid.
Limvann fåes ikke bare i den del av Glue water is not only available in that part of
fiskeindustrien som angår fisk slik som the fishing industry which concerns fish such as
sardiner, pilchards og hvitfisk, men også sardines, pilchards and whitefish, but also
den del som behandler hval, og uttrykket the part dealing with whales, and the phrase
limvann omfatter således også analoge pro-dukter som fåes fra hval. glue water thus also includes analogous products obtained from whales.
Limvann omfatter en vandig væske som Glue water comprises an aqueous liquid which
er rik på proteiner og vitaminer. Denne is rich in proteins and vitamins. This
væske anvendes vanligvis til fremstilling liquid is usually used for manufacturing
av dyrefor, men hittil er det ikke blitt funnet mulig å fremstille fra denne et proteinprodukt som er tilstrekkelig fritt for fiske-aktig smak og lukt til å være aksepterbart of animal feed, but so far it has not been found possible to produce from this a protein product which is sufficiently free of fishy taste and smell to be acceptable
menneskeføde. Det er nu blitt funnet mulig human food. It has now been found possible
fra limvann å fremstille en sirupaktig from glue water to produce a syrupy
væske eller et pulver som er tilstrekeklig liquid or a powder that is sufficient
fritt for smak og lukt til å være antagelig free from taste and smell to be acceptable
for menneskeføde, og som inneholder proteiner og/eller proteinhydrolyseprodukter for human consumption, and which contain proteins and/or protein hydrolysis products
i form som er lett fordøyelige og som bibe-holder en stor del av de vitaminer som er in a form that is easily digestible and that retains a large part of the vitamins that are
tilstede i limvannet, hvilket resulterer i et present in the glue water, resulting in a
produkt som i sammensetning kan sam-menlignes med en enzymekstrakt av lever. product whose composition can be compared to an enzyme extract of liver.
Tørrstoffbestanddelene i limvann består i det vesentlige av delvis vannoppløse-lige proteiner, B-vitaminer, salter og eter-ekstraherbare stoffer. Tørrstoffer i den The dry matter components in glue water essentially consist of partially water-soluble proteins, B vitamins, salts and ether-extractable substances. Solids in it
sirupaktige væske eller pulver som fåes syrupy liquids or powders obtained
ved hjelp av fremgangsmåten ifølge foreliggende oppfinnelse, består vesentlig av by means of the method according to the present invention, essentially consists of
aminosyrer, peptider, B-vitaminer og salter. Den sirupaktige væske eller pulver er prak-tisk fritt for eter-ekstrakherbare stoffer. amino acids, peptides, B vitamins and salts. The syrupy liquid or powder is practically free of ether-extractable substances.
Fremgangsmåten ifølge oppfinnelsen for fremstilling av et spiselig proteinprodukt av limvann er karakterisert ved at limvannet underkastes hydrolyse ved hjelp av syre, av hvilken minst halvparten er saltsyre, ved en surhetsgrad som ikke overskrider pH 1,0, og i et tidsrom som ikke overskrider 35 min., vesentlig ved kokepunktet og under atmosfærisk trykk, hvoretter væsken behandles med alkali inntil dens pH er fra 5—5,5 under opprettholdelse av temperaturen, hvoretter væsken fortynnes med vann og filtreres mens den fremdeles er varm, og filtratet underkastes fordampning under vakuum inntil destillatet ikke lenger er alkalisk, og det erholdte produkt, hvis ønskes, tørkes og pulveriseres eller forstøvningstørkes, eller blandes direkte med en spiselig bærer før tørk-ningen. The method according to the invention for producing an edible protein product from glue water is characterized in that the glue water is subjected to hydrolysis with the help of acid, of which at least half is hydrochloric acid, at an acidity that does not exceed pH 1.0, and for a period of time that does not exceed 35 min ., substantially at the boiling point and under atmospheric pressure, after which the liquid is treated with alkali until its pH is from 5-5.5 while maintaining the temperature, after which the liquid is diluted with water and filtered while still hot, and the filtrate is subjected to evaporation under vacuum until the distillate is no longer alkaline, and the product obtained is, if desired, dried and pulverized or spray-dried, or mixed directly with an edible carrier before drying.
Det er vel kjent å fremstille protein - hydrolysater ved hjelp av hydrolyse med It is well known to produce protein hydrolysates by means of hydrolysis with
syrer, alkali eller enzymer. Hydrolysen av faste proteiner med syrer nødvendiggjør bruk av høye konsentrasjoner av syrer og acids, alkali or enzymes. The hydrolysis of solid proteins with acids necessitates the use of high concentrations of acids and
bruk av temmelig høye temperaturer i lange use of fairly high temperatures for long periods
tidsrom. Dette resulterer i vesentlig øde-leggelse av vitamin B komplekser. Ved å underkaste proteinene i limvann sur hydrolyse, er det imidlertid blitt funnet mulig period of time. This results in substantial destruction of vitamin B complexes. However, by subjecting the proteins in glue water to acid hydrolysis, it has been found possible
å anvende en slik begrenset tid og milde betingelser for sur hydrolyse at B-vitamin-ene 1 det vesentlige bibeholdes og at amino-syretryptofan konserveres på et effektivt nivå mens samtidig proteinene hydrolyseres to use such a limited time and mild conditions for acid hydrolysis that the B vitamins 1 are essentially retained and that the amino acid tryptophan is conserved at an effective level while at the same time the proteins are hydrolysed
i tilstrekkelig grad til å gjøre dem meget lett fordøyelige. Det er tilstrekkelig at mengden og styrken av syren og tiden av-passes slik at det fåes et produkt som er filtr er bart varmt når det bringes til en pH på fra 5—5,5 og etter fortynning til et innhold av faste stoffer av ca. 25 vekts-pst. Hvis betingelsene er mere drastiske enn dette, vil det lett oppstå alvorlige tap av vitaminer. sufficiently to make them very easily digestible. It is sufficient that the amount and strength of the acid and the time are adjusted so that a product is obtained which is filtered and barely warm when it is brought to a pH of from 5-5.5 and after dilution to a solids content of approx. . 25 weight percent. If the conditions are more drastic than this, serious losses of vitamins will easily occur.
Det foretrekkes at surhetsgraden i væsken under hydrolysen ikke overskrider en pH på 1,0. Hydrolysetiden er fortrinsvis fra 20—30 min. Kratfig omrøring er ønskelig under den sure hydrolyse. It is preferred that the degree of acidity in the liquid during the hydrolysis does not exceed a pH of 1.0. The hydrolysis time is preferably from 20-30 min. Vigorous stirring is desirable during the acid hydrolysis.
Syren kan bestå av bare saltsyre eller av en blanding av saltsyre med en eller flere av følgende syrer, nemlig svovelsyre, eddiksyre og fosforsyre. The acid can consist of only hydrochloric acid or of a mixture of hydrochloric acid with one or more of the following acids, namely sulfuric acid, acetic acid and phosphoric acid.
Behandlingen av den sure oppløsning med alkali mens væsken er vesentlig ved kokepunktet, resulterer i en utvikling av ubehagelig luktende gasser. Kraftig om-røring er ønskelig også under alkalibe-handlingen. Den anvendte alkali er fortrinsvis natrium- og kaliumhydroksyd, og det er mest hensiktsmessig å anvende disse i slike mengder at de relative mengder av disse metaller i sluttproduktet er vesentlig seks vektsdeler natrium til ni vektsdeler kalium. For de fleste anvendelser av produktet er det ønskelig at natriuminnholdet ikke skal være særlig høyt. The treatment of the acidic solution with alkali while the liquid is substantially at the boiling point results in the evolution of unpleasant smelling gases. Vigorous stirring is also desirable during the alkali treatment. The alkali used is preferably sodium and potassium hydroxide, and it is most appropriate to use these in such amounts that the relative amounts of these metals in the final product are substantially six parts by weight of sodium to nine parts by weight of potassium. For most applications of the product, it is desirable that the sodium content should not be particularly high.
Den mengde vann som tilsettes før filtreringen er fortrinsvis tilstrekkelig til å gi en fortynnet væske som inneholder ca. 25 vekts-pst. tørrstoff. Filtreringen fjerner de uoppløste stoffer som omfatter etereks-traherbare stoffer. Mange av de ubehagelig luktende og smakende stoffer holdes tilbake på filteret, mens det hydrolyserte protein inneholdes i filtratet. Filtratet er en klar mørkebrun væske som har en kjøtt-aktig lukt og smak. The amount of water that is added before the filtration is preferably sufficient to give a diluted liquid containing approx. 25 weight percent. dry matter. The filtration removes the undissolved substances that comprise ether-extractable substances. Many of the unpleasant smelling and tasting substances are retained on the filter, while the hydrolysed protein is contained in the filtrate. The filtrate is a clear dark brown liquid that has a meat-like odor and taste.
Fordampingen av filtratet under va-kumm utføres fortrinsvis under et absolutt trykk på mindre enn 25 mm kvikk-sølv. Ubehagelig luktende gasser fjernes ved denne fordampning og smaken blir der-ved forbedret. Fordampningen fortsetter fortrinsvis inntil oppløsningen har en spe-sifikk vekt på ca. 1,25. På dette punkt er oppløsningen fremdeles klar. En tilsetning av litt eddiksyre til oppløsningen før fordampningen forbedrer smaken av produktet. The evaporation of the filtrate under vacuum is preferably carried out under an absolute pressure of less than 25 mm of mercury. Unpleasant smelling gases are removed by this evaporation and the taste is thereby improved. The evaporation preferably continues until the solution has a specific weight of approx. 1.25. At this point, the resolution is still clear. Adding a little acetic acid to the solution before evaporation improves the taste of the product.
Den dannede sirupaktige oppløsning kan blandes med et spiselig fast stoff, slik som et kornprodukt, f. eks. maismel og blandingen kan tørkes. Som et alternativ kan sirupen tørkes, fortrinsvis forstøv-ningstørkes. Det er ønskelig å regulere pH i sirupen til ca. 6,0, men den skal aldri over-skride 6,2. The resulting syrupy solution can be mixed with an edible solid, such as a grain product, e.g. cornmeal and the mixture can be dried. As an alternative, the syrup can be dried, preferably spray-dried. It is desirable to regulate the pH in the syrup to approx. 6.0, but it must never exceed 6.2.
En foretrukket form for oppfinnelsen vil bli beskrevet i det følgende ved hjelp av eksemplet. A preferred form of the invention will be described in the following with the help of the example.
Eksempel: Example:
455 kg flytende limvann som inneholder ca. en tredjedel av sin vekt protein an-bringes i et passende syrebestanding kar forsynt med rører og oppvarmningsanord-ninger. 455 kg liquid adhesive water containing approx. a third of its weight of protein is placed in a suitable acid-resistant vessel equipped with stirrers and heating devices.
68,0 kg 30 vektsprosent teknisk saltsyre settes til limvannet, røreren settes igang, og temperaturen økes jevnt til kokepunktet som er ca. 105° C. Blandingen holdes ved denne temperatur i ca. 20 min. Det er hverken nødvendig eller ønskelig å opphete under trykk. Etter denne tid av-brytes opphetningen og temperaturen til-lates å falle til ca. 80° C. 39,0 kg teknisk kaustisk sodaoppløsning, 40 vektsprosent, settes deretter langsom til, etterfulgt av 25,0 kg teknisk kaliumhydroksydoppløsning, 40 vektsprosent, med kraftig omrøring, 68.0 kg of 30% by weight technical hydrochloric acid is added to the glue water, the stirrer is started, and the temperature is increased steadily to the boiling point, which is approx. 105° C. The mixture is kept at this temperature for approx. 20 min. It is neither necessary nor desirable to heat under pressure. After this time, the heating is stopped and the temperature is allowed to fall to approx. 80° C. 39.0 kg technical caustic soda solution, 40% by weight, is then added slowly, followed by 25.0 kg technical potassium hydroxide solution, 40% by weight, with vigorous stirring,
hvorved blandingen oppvarmes til kokepunktet. 270 Itr. vann settes deretter til og blandingen omrøres kraftig i ca. 10 min. whereby the mixture is heated to the boiling point. 270 Itr. water is then added and the mixture is stirred vigorously for approx. 10 minutes
Den flytende blanding filtreres mens den fremdeles er varm. Den filtrerte væske skal være klar. Lukten og smaken skal ikke være bitter, og det skal være liten fiske-lukt sammenliknet med den opprinnelige oppløsning av fiskebestanddeler. Den spesifikke vekt skal være ca. 1,25 ved 15° C og pH ca. 5,5. The liquid mixture is filtered while still warm. The filtered liquid should be clear. The smell and taste should not be bitter, and there should be little fishy smell compared to the original dissolution of fish ingredients. The specific weight should be approx. 1.25 at 15° C and pH approx. 5.5.
Deretter settes eddiksyre til filtratet (1 Itr. teknisk eddiksyre for hver 454 ltr. Acetic acid is then added to the filtrate (1 Itr. technical acetic acid for every 454 ltr.
filtrat), hvoretter den fordampes under et absolutt trykk på høyst 25 mm kvikksølv til omtrent halvparten av sitt volum. Den dannede sirupaktige oppløsning har en spe-sifikk vekt på ca. 1,25 ved 15° C, og er ganske velsmakende. filtrate), after which it is evaporated under an absolute pressure of no more than 25 mm of mercury to about half its volume. The syrupy solution formed has a specific gravity of approx. 1.25 at 15° C, and is quite tasty.
Den kan lagres inntil bruk. It can be stored until use.
Hvis den forstøvningstørkes kan dens pH reguleres til 6,0 umiddelbart før sprøyte-tørkningen-. Forstøvningstørkning av sirupen som fremstilt ovenfor gir ca. 181 kg av et pulver som inneholder omtrent 60 pst. protein som er hydrolysert i en grad av 71 pst., og omfatter en adekvat mengde tryptofan. Produktet inneholder også en meget verdifull mengde riboflavin, nikotin-syre, vitamin Bi2 og cholin. If it is spray-dried, its pH can be adjusted to 6.0 immediately before spray-drying. Spray drying of the syrup as prepared above gives approx. 181 kg of a powder containing approximately 60 percent protein hydrolyzed to a degree of 71 percent, and comprising an adequate amount of tryptophan. The product also contains a very valuable amount of riboflavin, nicotinic acid, vitamin Bi2 and choline.
Pulveret er velsmakende, oppløses lett i melk eller vann og er helt skikket for menneskeføde. Dets høye innhold av fri aminosyre pluss oppløselige proteiner og kvaliteten av disse i forbindelse med dets The powder is tasty, dissolves easily in milk or water and is perfectly suitable for human consumption. Its high content of free amino acid plus soluble proteins and the quality of these in connection with its
nyttige innhold av B-vitaminer, gjør det useful content of B vitamins, it does

Hvis ønsket kan mengden av krystal-loide salter i den sirupaktige oppløsning If desired, the amount of crystalloid salts in the syrupy solution can
som fåes ved foreningen reduseres ved di-alyse. Det er imidlertid uønsket å fortsette which is obtained by the association is reduced by dialysis. However, it is undesirable to continue
dialysen i mere enn ca. 2 timer da dette kan the dialysis for more than approx. 2 hours as this can
nedsette produktets smak. reduce the taste of the product.
Som et alternativ kan det også frem-stilles et væskekonsentrat med lavt salt-innhold ved å sende den hydrolyserte og As an alternative, a liquid concentrate with a low salt content can also be produced by sending the hydrolysed and
filtrerte væske gjennom en ioneutveksler-kolonne, og fjerne overskudd av syre. Denne filtered liquid through an ion exchanger column, and remove excess acid. This
avsyrede og filtrerte væske kan deretter deacidified and filtered liquid can then
