Description
<Desc/Clms Page number 1>
Pour la préparation de peptone et d'amino-acide contenant des extraits à partir de l'eau comprimée, on a suggéré précédemment d'évaporer l'eau comprimée sous pression après l'addition d'acide pour la décomposition complète ou partielle des protéines et ensuite de traiter l'eau comprimée avec des enzymes telles que la pepsine afin de transformer éventuellement les protéines et les albumoses restantes en peptone.
Ce procédé exige des quantités considérables de chaleur et en outre la solution hautement acétique est fortement corrosive pour le matériel dans l'évaporateur pendant l'évaporation sous pression.
La présente Invention a pour objet une méthode par laquelle l'évaporation de la solution acétique sous pression est évitée par l'emploi d'enzymes spéciaux METHODE DE PREPARATION DE PEPTONE ET D'AMINO-ACIDE CONTENANT DES EXTRAITS A PARTIR DE L'EAU COMPRIMEE.
<Desc/Clms Page number 2>
comme produits de remplacement pour l'hydrolyse effectuée par évaporation sous pression de la solution acétique de protéines.
Lors du traitement de l'eau comprimée ,de manière connue,avec de la chaux, avec ou sans hydrolyse préalable à la pepsine, la valeur du pH suivant l'invention est augmentée de 8 à 9 et l'eau sous pression est amenée à une température de 35 à .0 C d'une manière connue, dans un bain d'eau ou au moyen d'une source de chaleur contrôlée par thermostat; les enzymes additionnels tels que la pancréatine et l'érepsine sont ensuite ajoutés jusqu'à ce que la rapidité d'hydrolyse optimum est atteinte. La chaux additionnée au préalable joue le rôle d'agent activant pour le trypsinogène de la pancréatine de manière à donner de la trypsine active.
Cet enzyme décompose une partie substantielle des protéines véritables contenues dans l'eau comprimée en amino-acides.
Les substances grasses contenues dans l'eau sous pression et dont l'enlèvement est autrement difficile,sont décomposées par la lipase de la pancréatine en acides gras et en glycérine. La lipase est activée de façon adéquate par une substance appropriée telle que la bile,l'agent activant étant ajouté lorsque l'hydrolyse est en route depuis un certain temps,par exemple depuis une heure.
Les acides gras libérés réagissent en présence de la chaux en formant des savons de chaux insolubles qui sont séparés en passant de manière connue,l'eau comprimée hydrolysée à travers un filtre de sable. Le filtre de sable retient aussi des particules non hydrolysées du filtrat.
L'eau filtrée est ensuite traitée de la manière connue dans un évaporateur sous vide. Le produit obtenu est un extrait dans lequel la plus grande partie des protéines de l'eau comprimée est complètement hydrolysée.
EXEMPLE . - Des essais ont été exécutés par évaporation sous le vide de I Kg d'eau comprimée de hareng contenant 0,4 pour cent de substances grasses, environ 3 pour cent de protéines dissoutes,environ 2 pour cent de substances protéiniques en suspension et quelques sels minéraux (environ 0,8 pour cent).-
I) L'eau comprimée non traitée avec de la chaux et de la pancréatine était d'abord évaporée de manière à augmenter le contenu de matière sèche d'environ 6% à environ 50%, avec un poids spécifique d'environ 1, 2 à 20& C .
Une analyse d'azote montrait environ 5,7 pour cent d'azote protéinique et 1, 02 pour cent d'azote sous forme d'amino-acides.
<Desc/Clms Page number 3>
2 ) L'eau comprimée traitée avec de, la chaux et de la pan- créatine pendant 5 heures, à un pH de 8, 5 et à une tem- pérature de 35 à 40 C était évaporée comme indiqué à l'essai ( 1 ).
L'analyse montrait 1,6 pour cent d'azote protéinique et
5,0 pour cent d'azote sous forme d'amino-acides.
L'azote sous forme d'amino-acide avait été déterminé par le titrage règlementaire suivant la méthode
S. P.L. Sorensen.
Lorsqu'on applique le traitement suivant la méthode décrite sous 2,1000 kg, l'eau comprimée cédera de 30 à 35 kg d'aminoacides, environ 10 kg de peptone et environ 7 Kg de sels minéraux.
Des essais ont cependant montré qu'une petite addition d'érepsine augmente l'effet de l'hydrolyse de manière à ac- croître la production à 45 kg d'amino-acides pour 1000 ks d'eau comprimée.
<Desc / Clms Page number 1>
For the preparation of peptone and amino acid containing extracts from compressed water, it was previously suggested to evaporate the compressed water under pressure after adding acid for complete or partial decomposition of proteins. and then treating the compressed water with enzymes such as pepsin in order to optionally convert the remaining proteins and albumoses into peptone.
This process requires considerable amounts of heat and furthermore the highly acetic solution is highly corrosive to the material in the evaporator during evaporation under pressure.
The present invention relates to a method by which the evaporation of the acetic solution under pressure is avoided by the use of special enzymes METHOD OF PREPARATION OF PEPTONE AND AMINO ACID CONTAINING EXTRACTS FROM COMPRESSED WATER .
<Desc / Clms Page number 2>
as substitutes for hydrolysis carried out by pressure evaporation of the acetic protein solution.
During the treatment of compressed water, in a known manner, with lime, with or without prior hydrolysis with pepsin, the pH value according to the invention is increased from 8 to 9 and the pressurized water is brought to a temperature of 35 to .0 C in a known manner, in a water bath or by means of a heat source controlled by thermostat; additional enzymes such as pancreatin and erepsin are then added until the optimum hydrolysis rate is reached. The lime added beforehand acts as an activating agent for the trypsinogen of pancreatin so as to give active trypsin.
This enzyme breaks down a substantial part of the true proteins in compressed water into amino acids.
The fatty substances in pressurized water, which are otherwise difficult to remove, are broken down by the lipase of pancreatin into fatty acids and glycerin. The lipase is suitably activated by a suitable substance such as bile, the activating agent being added when hydrolysis has been on for some time, for example for an hour.
The liberated fatty acids react in the presence of lime forming insoluble lime soaps which are separated by passing, in a known manner, the hydrolyzed compressed water through a sand filter. The sand filter also retains unhydrolyzed particles from the filtrate.
The filtered water is then treated in the known manner in a vacuum evaporator. The product obtained is an extract in which most of the proteins in the compressed water are completely hydrolyzed.
EXAMPLE. - Tests were carried out by vacuum evaporation of 1 kg of compressed herring water containing 0.4 percent fatty substances, approximately 3 percent dissolved protein, approximately 2 percent suspended protein substances and some salts minerals (about 0.8 percent) .-
I) The compressed water not treated with lime and pancreatin was first evaporated so as to increase the dry matter content from about 6% to about 50%, with a specific gravity of about 1, 2 at 20 & C.
Nitrogen analysis showed about 5.7 percent protein nitrogen and 1.02 percent nitrogen as amino acids.
<Desc / Clms Page number 3>
2) Compressed water treated with de, lime and pancreatine for 5 hours, at a pH of 8.5 and at a temperature of 35 to 40 C was evaporated as indicated in test (1 ).
The analysis showed 1.6 percent protein nitrogen and
5.0 percent nitrogen as amino acids.
Nitrogen in the form of amino acid had been determined by the regulatory titration according to the method
S. P.L. Sorensen.
When applying the treatment according to the method described under 2.1000 kg, the compressed water will yield from 30 to 35 kg of amino acids, approximately 10 kg of peptone and approximately 7 kg of mineral salts.
However, tests have shown that a small addition of erepsin increases the effect of hydrolysis so as to increase the production to 45 kg of amino acids per 1000 ks of compressed water.
