Abstract
Aminopeptidases originating from Aspergilli niger are disclosed, which can be produced in a fermentation broth or a liquid concentrate thereof substantially free of endoprotease. Such aminopeptidases may be advantageously employed in the food industry, e.g. in the preparation of bread doughs or cheese.
Claims9
An aminopeptidase composition comprising an Aspergillus niger aminopeptidase contained in a fermentation broth filtrate or a liquid concentrate thereof wherein the composition has 10 times more units of aminopeptidase activity than units of endoprotease activity and the aminopeptidase is phenylalanine aminopeptidase and/or leucine aminopeptidase.
