Gegenstand der Erfindung ist ein Verfahren zur Herstellung von für die menschliche Ernährung geeignetem Eiweißhydrolysat aus Schlachtabfällen und/oder aus Schlachtnebenprodukten, insbesondere aus Schweinsköpf, Schweinshaxe und Schwarten. Durch das erfindungsgemäße Verfahren kann eine wertvolle, hauptsächlich in der Fleischindustrie verwendbare Lebensmittelergänzung mit relativ hohem Eiweißgehalt gewonnen werden.The invention relates to a process for the production of protein hydrolyzate suitable for human consumption from slaughterhouse waste and / or from slaughtering by-products, in particular from pig's head, pork knuckle and rinds. A valuable food supplement with a relatively high protein content, which can be used mainly in the meat industry, can be obtained by the method according to the invention.
Die Behandlung und gegebenenfalls die Aufarbeitung der Schlachtnebenprodukte und -abfälle zu einem wertvollen Produkt beschäftigt die Fachwelt schon seim langem. Die schon lange bekannte Aufarbeitung mit derThe treatment and, if necessary, the processing of slaughter by-products and waste into a valuable product has long been of interest to the professional world. The well-known workup with the
Hand - z.B. das Zerlegen des Schweinskopfes - ist einerseits schwere physische Arbeit, andererseits sehr zeiraufwendig, so wird diese Art der Aufarbeitung kaun nech angewandt.Hand - e.g. the cutting of the pig's head - on the one hand is hard physical work, on the other hand very time-consuming, so this type of processing is not used at all.
Zur Aufarbeitung dieser Nebenprodukte und Abfälle sind chemische, mit Säuren arbeitende Verfahren bekannt, welche - darüber hinaus, daß die saure Hydrolyse lang dauert - Produkte mit hohem Chemikaliengehalt hervorbringen. Die erhöhte Ionenkonzentration dieses Produktes ist aus ernährungstechnisch-gesundheitlichen Gründen nicht erwünscht.For the processing of these by-products and wastes, chemical processes which work with acids are known which, in addition to the fact that the acid hydrolysis takes a long time, produce products with a high chemical content. The increased ion concentration of this product is not desirable for nutritional reasons.
Zur Aufarbeitung der Schlachtnebenprodukte wurden zahlreiche Verfahren ausgearbeitet, die auf der
Verwendung von proteolytischen Enzymen verschiedenen Ursprungs beruhen. Es wurden Versuche unter Verwendung von Enzymen pflanzlichen, tierischen und mikrobiellen Ursprungs durchgeführt, z.B. mit Papain, Fivin, Bromelin, Trypsin, Chymotrypsin oder Pankreatin.Numerous processes have been developed to process the slaughter by-products Use of proteolytic enzymes of various origins are based. Experiments have been carried out using enzymes of plant, animal and microbial origin, for example with papain, fivin, bromelin, trypsin, chymotrypsin or pancreatin.
In der US-PS Nr. 3 098014 wird ein Verfahren zum Ablösen von Fleischresten vom Knochen unter Anwendung des Enzyms Papain beschrieben. Als Grundmaterial werden Hühnerhals oder gehackte Rindsknochen verwendet, welche in Wasser bei 71 - 77 °C in Gegenwart von Papain eine Stunde lang wärmebehandelt werden, dann wird die Temperatur auf 99 ºC erhöht und 20 Minuten lang gehalten. Darauffolgend läßt man die harten Komponenten sich ablagern.US Pat. No. 3,097,014 describes a method for detaching meat residues from the bone using the enzyme papain. As the base material, chicken neck or chopped beef bones are used, which are heat-treated in water at 71-77 ° C in the presence of papain for one hour, then the temperature is raised to 99 ° C and held for 20 minutes. The hard components are then allowed to deposit.
Im Endergebnis wurden 46 % der eingeführten Schlachtabfälle zu Hydrolysat verarbeitet.In the end, 46% of imported slaughter waste was processed into hydrolyzate.
Gemäß der US-PS Nr. 3 276 880 wurde die Enzymbehandlung in Gegenwart von 1 - 5 % Natriumchlorid bei einer Temperatur von 0 - 18 °C durchgeführt. Man erhält eine homogene Masse, die die zusammenhaltende Matrix der Fleischerzeugnisse bildet. Das mit dem auf diese Weise hergestellten Brei erzeugte Fleischpräparat enthält auch eiweißspaltende Enzyme, deren Gegenwart im Produkt von den Erfindern als vorteilhaft befunden wird.According to US Pat. No. 3,276,880, the enzyme treatment was carried out in the presence of 1-5% sodium chloride at a temperature of 0-18 ° C. A homogeneous mass is obtained which forms the cohesive matrix of the meat products. The meat preparation produced with the porridge produced in this way also contains protein-splitting enzymes, the presence of which in the product is found to be advantageous by the inventors.
Gemäß der US-PS Nr. 4 175 199 wird aus Rinderknochen mittels eines auf Papain beruhenden proteolytischen Enzyms Hydrolysat hergestellt, indem man den gehackten Knochen in Gegenwart von Papain 4 - 6 Stunden lang bei einer Temperatur, die 90 °C nicht überschreitet, in Wasser kocht, dann die festen Komponenten und das Fett entfernt. Am Ende gewinnt man eine
Lösung mit einem Eiweißgehalt von 4 - 7 %. Zum Zwecke des leichteren Überführens der Eiweiße in Lösung werden auch maximal 2 % Natriumchlorid in das System gegeben.According to U.S. Patent No. 4,175,199, bovine bones are made from papain-based proteolytic enzyme to hydrolyze by chopping the bones in water in the presence of papain for 4-6 hours at a temperature not exceeding 90 ° C boils, then the solid components and the fat are removed. In the end you win one Solution with a protein content of 4 - 7%. To facilitate the transfer of the proteins into solution, a maximum of 2% sodium chloride is also added to the system.
In der US-PS Nr. 4 402 873 wird ein Verfahren zur Aufarbeitung von im Schlachthof anfallenden, noch Fleischreste enthaltenden Schweinsknochen beschrieben, das Hydrolysat mit einem Eiweißgehalt von 4 - 7 % als Ergebnis aufweist. Die Knochen werden in Gegenwart von Papain bei 57 - 63 °C in Wasser behandelt, dann wird die Temperatur auf 90 °C erhöht. Das Filtern und Entfernen des Fettes wird bei 66 °C durchgeführt. Das Enzym rapain 90L wird auf das Gewicht des Knochens bezogen in einer Menge von 1 % verwendet.US Pat. No. 4,402,873 describes a process for working up pork bones that still result in meat from the slaughterhouse and that contains hydrolyzate with a protein content of 4-7% as a result. The bones are treated in the presence of papain at 57-63 ° C in water, then the temperature is raised to 90 ° C. The filtering and removal of the fat is carried out at 66 ° C. The enzyme rapain 90L is used in an amount of 1% based on the weight of the bone.
Ziel der Erfindung war die Erarbeitung eines Verfahrens, welches neben den bekannten auch neuen Anforderungen gerecht wird und im Vergleich zu den bekannten Verfahren billiger, wirtschaftlicher und ertragreicher zur Herstellung von in der Nahrungsmittelindustrie, besonders in der Fleischindustrie, verwendbarem Eiweißhydrolysat geeignet ist.The aim of the invention was to develop a method which, in addition to the known and also new requirements, is suitable and, compared to the known methods, is cheaper, more economical and more profitable for the production of protein hydrolyzate which can be used in the food industry, in particular in the meat industry.
Während der Fleischverarbeitung entstehen beispielsweise in großer Menge Schweinskopf, Schweineschwarte und Schweinshaxe, die teils nur in begrenzter Menge auf den Markt gebracht werden können, teils ist ihre Weiterverarbeitung gegenwärtig nur teilweise gelöst. Bei uns finden z.B. etwa 40 % der jährlich entstehenden mehreren Zehntausend Kilogramm Schweinskopf in Fleischprodukten mit Schweinskopf als Grundbestandteil Verwendung, zur Aufarbeitung der restlichen 60 % stand bis jetzt kein entsprechendes Verfahren zur Verfügung. Eine Hauptursache dafür besteht
darin, daß für die Aufarbeitung des Schweinskopfes infolge seines Aufbaus außerordentlich viel Haniarbeit erforderlich ist. Die gegenwärtig etwa 40 % zur Verarbeitung gelangenden Schweinskopf werden nach iem Reinigen vorgekocht, dann werden aus dem vorgedrehtenDuring meat processing, for example, pork heads, pork rinds and pork knuckles are produced in large quantities, some of which can only be brought onto the market in limited quantities, and some of their further processing is currently only partially resolved. For example, we use about 40% of the tens of thousands of kilograms of pork's head that are produced annually in meat products with pork's head as a basic component, so far no corresponding process has been available to process the remaining 60%. A major cause of this is there in the fact that an extraordinary amount of manual work is required to process the pig's head due to its structure. The pig's head, which is currently about 40% ready for processing, is pre-cooked after cleaning, then the pre-turned one
Kopf die Knochen entfernt und die wertvolleren Fleischstücke ausgewählt. Dieser Vorgang ist zeitaufwendig und schwierig.Head the bones removed and the more valuable pieces of meat selected. This process is time consuming and difficult.
Es wurde ein neues Verfahren zur Aufarbeirung von Schlachtabfällen und/oder Schlachtnebenprodukten, z.B. von Schweinskopf, ausgearbeitet, das auf enzymatischer Verdauung basiert. Im Endergebnis erhält man Fleisch- und Bindegewebseiweiße enthaltendes Hydrolysat mit einem Trockenstoffgehalt von 10 - 35 % . Das durch dieses Verfahren gewonnene Hydrolysat kann zur Herstellung von Rotwaren, Aufschnitten und Näseprodukten anstelle der bisher zur Verfügung stehenden Emulsionen und erfolgreicher als diese verwender werden.A new process for the processing of slaughter waste and / or slaughter by-products, e.g. of pig's head, elaborated based on enzymatic digestion. The end result is hydrolyzate containing meat and connective tissue proteins with a dry matter content of 10-35%. The hydrolyzate obtained by this process can be used for the production of red goods, cold cuts and cheese products instead of the previously available emulsions and more successfully than these.
Während des erfindungsgemäßen Verfahrens wird das Ausgangsmaterial in Wasser von zweckmäßigerweise der 0,8 - 2,2-fachen Menge und 90 - 98 °C Vorgekecht. Im Gegensatz zu den bekannten Verfahren wird virher nicht zerhackt oder zerkleinert. Das hat den Vorteil, daß das Zielprodukt keine Mikro-Knochensplitter enthält. So ist es einerseits nicht notwendig, einen Filtrationsschritt zwischenzuschalten, andererseits ist das Produkt sicher als Matrixmaterial bei Produkten der Fleischindustrie verwendbar.During the process according to the invention, the starting material is expediently pre-treated in water of 0.8-2.2 times the amount and 90-98 ° C. In contrast to the known methods, virher is not chopped or crushed. This has the advantage that the target product does not contain any micro-bone fragments. On the one hand, it is not necessary to interpose a filtration step, on the other hand, the product can be safely used as a matrix material in products from the meat industry.
Mit Beendigung des Vorkochens wird die Cenperatur des Gemisches zweckmäßigerweise mittels einer temperierbaren, mit Rührplatten ausgestatteten Zrehapparatur auf 50 - 65 °C eingestellt. Darauffolgend
wird in einer Konzentration von 0,15 - 0,30 % neutrale Protease, vorzugsweise Colorase N, hinzugegeben und 30 - 36 Minuten lang durch Drehen mit 12 - 17 Umdrehungen/Minute eine intensivierte Enzymbehandlung durchgeführt. Am Ende der Behandlung wird die feste Phase aus dem Gemisch isoliert, dann die Temperatur der flüssigen Phase auf 92 - 98 °C (praktisch fast bis zum Kochen) erhöht, um das Enzym zu inaktivieren. Nach dem Erwärmen wird das obenauf schwimmende Fett entfernt und erneut filtriert, wobei ein Filter mit kleineren Löchern verwendet wird. Schließlich wird die Flüssigphase abgekühlt, zweckmäßigerweise auf eine Temperatur um 0 ºC.When the pre-cooking is complete, the temperature of the mixture is expediently set to 50-65 ° C. by means of a temperature-controlled rotating apparatus equipped with stirring plates. Subsequent neutral protease, preferably Colorase N, is added at a concentration of 0.15-0.30% and an intensified enzyme treatment is carried out for 30-36 minutes by rotating at 12-17 revolutions / minute. At the end of the treatment, the solid phase is isolated from the mixture, then the temperature of the liquid phase is raised to 92-98 ° C. (practically almost to the boil) in order to inactivate the enzyme. After heating, the fat floating on top is removed and filtered again using a filter with smaller holes. Finally the liquid phase is cooled, suitably to a temperature around 0 ° C.
Das auf diese Weise hergestellte Produkt enthält 10 - 35 % Trockensubstanz, unter anderem hydrolysiertes Fleisch- und Bindegewebseiweiß. Z.B. gehen mehr als 50 % der Ausgangsmenge in Lësung.The product produced in this way contains 10-35% dry matter, including hydrolyzed meat and connective tissue protein. For example, more than 50% of the original amount goes into solution.
Der Eiweiß- und Kreatingehalt der Produkte der Fleischindustrie, die durch das erfindungsgemäße Verfahren hergestelltes Hydrolysat enthalten, erhöht sich, und außerdem werden diese Fleischprodukte reicher an allgemein wertvollen Stoffen. Die Verarbeitung des Hydrolysats bedeutet Auslösung des Fleischeiweißes; durch Verarbeitung in Produkten höherer Preislage kann die Wirksamkeit in großem Maße erhöht werden.The protein and creatine content of the products of the meat industry, which contain hydrolyzate produced by the process according to the invention, increases, and moreover these meat products become richer in generally valuable substances. Processing the hydrolyzate means releasing the meat protein; The effectiveness can be increased to a great extent by processing in products of a higher price range.
Das erfindungsgemäße Verfahren wird anhand der folgenden Beispiele erläutert, ohne daß der Schutzanspruch auf diese eingeschränkt wird.
