Abstract
Description
L'invention concerne un procédé de décoloration de sang animal et le sang décoloré ainsi obtenu. The invention relates to a process for discoloration of animal blood and to the discolored blood thus obtained.
Le sang animal est produit par les abattoirs en grandes quantités. Il s'agit là d'un produit dont les utilisations connues (fabrication de boudins par exemple) laissent des excédents dont on ne sait trop que faire en dépit du fait que ce sang contient des constituants (protéines) qui seraient potentiellement intéressants0 Le principal obstacle à l'emploi du sang animal réside dans sa coloration rouge qui est rédhibitoire pour la commercialisation des produits qui pourraient être fabriqués à partir de ce sang. Animal blood is produced in large quantities by slaughterhouses. This is a product whose known uses (manufacture of sausages for example) leave surpluses which we do not know what to do despite the fact that this blood contains constituents (proteins) which would be potentially interesting0 The main obstacle for the use of animal blood resides in its red coloration which is prohibitive for the marketing of products which could be produced from this blood.
L'invention vise à fournir un procédé de traitement du sang qui permet de le décolorer sans altérer substantiellement la nature de ses constituants potentiellement intéressants tels que les protéines, et qui permet, contrairement à d'autres procédés connus (basés sur l'utilisation d'acétone, d'acide ascorbique, de nitrites ou d'eau oxygénée) de conserver la partie hémique et le fer de l'hémoglobine0
Plus particulièrement l'invention concerne un procédé de décoloration du sang qui consiste à faire passer dans le sang, par exemple par barbotage, un mélange gazeux contenant de ltoxygène et de l'ozone pendant une durée suffisante pour assurer la décoloration, le pWdu sang étant dans la gamme acide.The invention aims to provide a method of treating blood which makes it possible to discolor it without substantially altering the nature of its potentially interesting constituents such as proteins, and which allows, unlike other known methods (based on the use of acetone, ascorbic acid, nitrites or hydrogen peroxide) to keep the heme part and the iron of hemoglobin
More particularly the invention relates to a process for bleaching blood which consists in passing into the blood, for example by bubbling, a gaseous mixture containing oxygen and ozone for a sufficient time to ensure discoloration, the pW of blood being in the acid range.
Aux fins de l'invention, le terme "sang" couvre aussi bien le sang entier que le cruor. For the purposes of the invention, the term "blood" covers both whole blood and cruor.
Le traitement de décoloration de l'invention doit être effectué sur du sang acide car un pH basique décompose ozone. On peut traiter par le procédé de l'invention le sang de n'importe quel animal, par exemple de bovins, de porcs, de moutons et de chevaux. The bleaching treatment of the invention must be carried out on acidic blood because a basic pH decomposes ozone. The blood of any animal, for example cattle, pigs, sheep and horses, can be treated by the method of the invention.
Le traitement de décoloration de l'invention peut être mis en oeuvre sur du sang entier si on opère la décoloration dans l'abattoir sitat le sang recueilli, ou sur du sang ou du cruor convenablement dilué si on opère la décoloration ultérieurement0 La dilution du sang ou du cruor peut se faire, par exemple, dans une solution aqueuse d'un acide approuvé par les réglementations dans le domaine alimentaire, tel que l'acide citrique. The bleaching treatment of the invention can be carried out on whole blood if the bleaching is carried out in the slaughterhouse when the blood is collected, or on blood or cruor suitably diluted if the bleaching is carried out subsequently. or cruor can be made, for example, in an aqueous solution of an acid approved by regulations in the food field, such as citric acid.
Le mélange gazeux doit contenir suffisamment d'ozone pour produire la décoloration en un temps raisonnable. A titre indicatif, il faut que le mélange gazeux contienne au moins 0,196 en volume d'ozone, de préférence au moins i96 en volume. Outre ltoxygène et l'ozone, -le mélange gazeux pourrait contenir d'autres gaz inertes tels que l'azote. En particulier, -on peut employer comme mélange gazeux de l'air ozoné. The gas mixture must contain enough ozone to produce discoloration within a reasonable time. As an indication, the gas mixture must contain at least 0.196 by volume of ozone, preferably at least 196 by volume. In addition to oxygen and ozone, the gas mixture could contain other inert gases such as nitrogen. In particular, ozone air can be used as the gas mixture.
La température de traitement n'est pas très critique et peut aller par exemple de 0 à 500C. Toutefois, il y a avantage à opérer à une température relativement basse (5 à 15 : par exemple) car on a observé que le temps de décoloration diminuait avec la température, probablement par suite d'une solubilité accrue de l'ozone à basse température. Le traitement de l'invention présente, en outre, l'avantage de ne pas laisser de traces d'ozone dans le produit obtenu. The treatment temperature is not very critical and can range, for example, from 0 to 500C. However, it is advantageous to operate at a relatively low temperature (5 to 15: for example) because it has been observed that the discoloration time decreases with temperature, probably due to an increased solubility of ozone at low temperature. . The treatment of the invention also has the advantage of not leaving traces of ozone in the product obtained.
Les exemples non limitatifs suivants sont donnés afin d'illustrer l'invention. The following nonlimiting examples are given in order to illustrate the invention.
Dans les exemples qui suivent, on a utilisé un ozoneur fonctionnant sous une tension primaire de 105 volts et dont le potentiel de charge (entre les électrodes) était de 22000 volts. Le mélange gazeux produit par l'ozo- neur contenait, en volume, environ 9tus6 d'oxygène et 5,6 d'ozone. Le débit du gaz était de 0,96 litre/minute. La pression du gaz était de 1 bar. Le sang à décolorer, placé dans un récipient convenable, était soumis à une agitation par un agitateur à pale, tournant à 345 tours/minute pendant le barbotage du mélange gazeux. On a utilisé dans - chaque cas une solution-mère constituée de sang de vaches (préalablement congelé) diluée par une quantité égale d'une solution aqueuse à 2,6 en poids d'acide citrique.La température de traitement était de 150C environ. In the following examples, an ozonizer operating at a primary voltage of 105 volts was used, the charge potential of which (between the electrodes) was 22,000 volts. The gas mixture produced by the ozone generator contained, by volume, about 9 tus6 of oxygen and 5.6 ozone. The gas flow rate was 0.96 liters / minute. The gas pressure was 1 bar. The blood to be discolored, placed in a suitable container, was stirred by a paddle stirrer, rotating at 345 rpm during the bubbling of the gas mixture. In each case, a stock solution consisting of cow blood (previously frozen) diluted with an equal amount of an aqueous solution containing 2.6% by weight of citric acid was used. The treatment temperature was approximately 150 ° C.
Exemple 1
On a traité dans les conditions susudéfinies 600 ml de solution-mère diluée au 1/15 par une solution aqueuse d'acide citrique à 1% en poids, à laquelle on avait ajouté 5 ml d'heptanol à titre d'agent anti-mousse. Le pH du sang dilué était de 2,35.Example 1
600 ml of mother solution diluted 1/15 was treated under the above conditions with an aqueous solution of citric acid at 1% by weight, to which 5 ml of heptanol had been added as anti-foaming agent. . The pH of the diluted blood was 2.35.
Au bout de 15 minutes de barbotage on a obtenu un liquide laiteux de pH pratiquement inchangé. After 15 minutes of bubbling, a milky liquid of practically unchanged pH was obtained.
Exemple 2
On a traité dans les conditions sus-définies 500 ml de solution-mère diluée au 1/3 par une solution aqueuse d'acide citrique à 1,6 en poids, à laquelle on avait ajouté 5 ml d'heptanol à titre d'agent anti-mousse.Example 2
500 ml of mother solution diluted 1/3 were treated under the above-defined conditions with an aqueous solution of citric acid at 1.6 by weight, to which 5 ml of heptanol had been added as agent. anti-foam.
Le pH du sang dilué était de 2,90. The pH of the diluted blood was 2.90.
A u bout de 2h 30 on a obtenu un liquide laiteux présentant quelques dépits, de pH inchangé. At the end of 2 h 30 min, a milky liquid was obtained with a few parts, of unchanged pH.
La consommation d'ozone était d'environ 2 mg/ litre de sang dilué et par minute. Ozone consumption was approximately 2 mg / liter of diluted blood per minute.
Exemple 3
On a traité dans les conditions sus-définies 300 ml de solution-mère diluée au 1/2 par une solution aqueuse d'acide citrique à 1,6 en poids, à laquelle on avait ajouté 5 ml d'heptanol à titre d'agent anti-mousse. Le pH du sang dilué n'a pas été mesuré.Example 3
300 ml of stock solution diluted 1/2 with an aqueous solution of citric acid at 1.6 by weight, to which 5 ml of heptanol were added as agent, were treated under the above-defined conditions. anti-foam. The pH of the diluted blood has not been measured.
Au bout de 4 heures, on a obtenu un produit blanc-gris. After 4 hours, a white-gray product was obtained.
Exemple 4
On a observé l'évolution des produits obtenus dans les exemples précédents au cours d'un stockage à 40C pendant 10 jours. Les résultats ont été les suivants
Exemple Couleur Formation de déps
1 sans changement non
2 sans changement oui
3 sans changement devient gélatineux
Le sang décoloré obtenu par le procédé de l'invention est susceptible entre utile comme additif alimentaire0
Il va de soi que les modes de réalisation décrits ne sont que des exemples et qu'on pourrait les modifier, notamment par substitution d'équivalents techniques, sans sortir pour cela du cadre de l'invention. Example 4
The evolution of the products obtained in the previous examples was observed during storage at 40C for 10 days. The results were as follows
Example Color Dice formation
1 without change no
2 no change yes
3 unchanged becomes gelatinous
The discolored blood obtained by the process of the invention is susceptible between useful as a food additive
It goes without saying that the embodiments described are only examples and that they could be modified, in particular by substitution of technical equivalents, without departing from the scope of the invention.
