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.
Claims19
A composition comprising an Aspergillus niger aminopeptidase preparation and an enzymatic cheese-making coagulant wherein said preparation has 10 times more units of aminopeptidase activity than units of endoprotease activity and the aminopeptidase activity is phenylalanine aminopeptidase and/or leucine aminopeptidase.
A composition comprising an Aspergillus niger aminopeptidase preparation and a neutral protease, wherein said preparation has 10 times more units of aminopeptidase activity than units of endoprotease activity and the aminopeptidase activity is phenylalanine aminopeptidase and/or leucine aminopeptidase.
In a medium for production of a starter culture for the production of fermented food products wherein the improvement comprises an Aspergillus niger aminopeptidase, wherein the Aspergillus niger aminopeptidase has 10 times more activity of aminopeptidase than units of endoprotease and the aminopeptidase activity is phenylalanine aminopeptidase and/or leucine aminopeptidase.
In a food product or food preparation intermediate containing aminopeptidase wherein the improvement comprises a preparation of Aspergillus niger aminopeptidase wherein the Aspergillus niger aminopeptidase has 10 times more activity of aminopeptidase than units of endoprotease and the aminopeptidase activity is phenylalanine aminopeptidase and/or leucine aminopeptidase.
In a baked product dough wherein the improvement comprises Aspergillus niger aminopeptidase, wherein the aminopeptidase wherein the Aspergillus niger aminopeptidase has 10 times more activity of aminopeptidase than units of endoprotease and the aminopeptidase activity is phenylalanine aminopeptidase and/or leucine aminopeptidase.
