Summary

The haemoglobin from slaughter house blood is a waste produce due to the colour and off-flavour. Many methods for the decolorization of haemoglobin have been described; they are often unsatisfactory for operation on an industrial scale. This study demonstrates the use of aluminium oxide in order to decolorize a peptic hydrolysate of bovine blood. Peptides were obtained by this method both on the laboratory and pilot plant scale.

Résumé

L'hémoglobine provenant du sang d'abattoir est actuellement considérée comme un déchet, ceci à cause de sa couleur et de son odeur désagréable. Plusieurs méthodes de décoloration de l'hémoglobine ont été décrites; elles ne sont souvent applicables à l'échelle industrielle. Ce travail montre l'utilisation de l'alumine pour décolorer un hydrolysat pepsique de sang bovin. Des peptides ont été obtenus par cette méthode à la fois au laboratoire et au stade pilote.

Resumen

La hemoglobina obtenida a partir de sangre de matadero es un producto no aprovechable debido a su color y mal olor. Se han descrito muchos métodos para decolarar la hemoglobina, pero estos no son generalmente adecuados para su utilización industrial. En este estudio se demuestra el uso del óxido de aluminio para la decoloración de un hidrolizado peptídico de sangre bovina. Los péptidos se obtuvieron tanto a escala de laboratorio como a escala semiindustrial en una planta piloto.
