Abstract
The invention relates to a method for the prevention or reduction of haze in a beverage by the addition of a prolyl-specific and/or alamine specific endoprotease and the new beverages obtainable by the method according to the invention. It also relates to new endoproteases. It also relates to methods as described above wherein auxiliary enzymes are used in combination with the specific endoprotease. Sequence information of a genomic DNA, cDNA as well as protein sequences are provided.
Claims10
A method for the prevention or reduction of haze in a beverage ready for consumption comprising:
- (a) adding a prolyl-specific endoprotease that cuts a protein or peptide at places where the protein or peptide contains a prolyl residue to the beverage, wherein the prolyl-specific endoprotease is comprised of an amino acid sequence which has at least 95% sequence identity with the amino acid sequence of SEQ ID NO:5 and
- (b) adding an auxiliary proteolytic enzyme to the beverage, wherein addition of said auxiliary proteolytic enzyme results in further prevention or reduction of haze than is achievable with the prolyl-specific endoprotease alone, wherein said auxiliary proteolytic enzyme is a glycine-specific endoprotease and/or an aspartic acid protease.
A method for the prevention or reduction of haze in a beverage ready for consumption comprising:
- (a) adding a prolyl-specific endoprotease that cuts a protein or peptide at places where the protein or peptide contains a prolyl residue to the beverage, wherein the prolyl-specific endoprotease is comprised of an amino acid sequence which has at least 95% sequence identity with the amino acid sequence of SEQ ID NO:5 and
- (b) adding an auxiliary proteolytic enzyme to the beverage, wherein addition of said auxiliary proteolytic enzyme results in further prevention or reduction of haze than is achievable with the prolyl-specific endoprotease alone, wherein said auxiliary proteolytic enzyme is an aspartic protease obtained from Rhizomucor miehei.
