A method is disclosed for stabilizing liquid enzyme-containing liquid formulations by adding at least one boron compound and at least one alpha- hydroxy-mono-carboxylic acid or the salt of an alpha-hydroxy-mono-carboxylic acid capable of forming an enzyme~stabilizing compound. An enzyme-stabilized formulation is disclosed comprising an alpha~hydroxy-mono-carboxylic acid or the salt of an alpha-hydroxy-mono-carboxylic acid, a boron containing compound capable complexing with an alpha-hydroxy-mono-carboxylic acid, the complex formed by the boron compound and the an alpha-hydroxy-mono~carboxylic acid, and an enzyme. The invention applies to both enzyme concentrate raw materials, and to useful product formulations.
L'invention concerne un procédé destiné à stabiliser des préparation liquides contenant des enzymes par addition d'au moins un composé de bore et d'au moins un acide alpha-hydroxy-mono-carboxylique ou du sel d'un acide alpha-hydroxy-mono-carboxylique permettant de former un composé de stabilisation enzymatique. L'invention concerne une préparation à stabilisation enzymatique renfermant un acide alpha-hydroxy-mono-carboxylique ou le sel d'un acide alpha-hydroxy-mono-carboxylique, le complexe formé par le composé de bore et l'acide alpha-hydroxy-mono-carboxylique, ainsi qu'une enzyme. L'invention se rapporte en outre à des matières brutes sous forme de concentrés enzymatiques ainsi qu'à des préparations produites utiles.
