Abstract
Official abstract text for this publication.
The present invention relates to endoproteases. More particularly, the present invention relates to the use of endoproteases for reduction or elimination of beer haze.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for the reduction or prevention of haze in a beverage comprising adding an endoprotease to the beverage, wherein said endoprotease is an enzyme having at least 75, 80, 85, 90, 95, 98, 99 or 100% sequence identity to SEQ ID NO:1 or an endoprotease active fragment thereof such as a mature protein. 2 . The method of claim 1 wherein the endoprotease active fragment is a mature protein. 3 . The method of claim 2 wherein the beverage contains proteins. 4 . The method of claim 3 wherein the beverage contains polyphenols. 5 . The method of claim 4 wherein the beverage is a beer. 6 . The method of claim 4 wherein the beverage is a wine. 7 . The method of claim 4 wherein the beverage is a fruit juice. 8 . The method of claim 5 wherein the endoprotease is added to a wort. 9 . The method of claim 5 wherein the endoprotease is added to a beer after haze has been formed. 10 . The method of claim 5 wherein the endoprotease is added to a beer before haze has been formed. 11 . The method of claim 5 wherein the beer has an increased relative foam stability and an increased relative haze reduction. 12 . The method of claim 11 wherein the increased relative foam stability is above 100, 101, 102, 103, 104, 105, 106, 107, 108, 109 or 110%. 13 . The method of claim 11 wherein the increased relative haze reduction is above 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80% as measured by 90° scattering. 14 . The method of claim 8 wherein the endoprotease is present in the wort in an amount of 4 to 300 mg protease/hL wort, 10 to 250 mg protease/hL wort, 20 to 200 mg protease/hL wort, 30 to 150 mg protease/hL wort or 40 to 100 mg protease/hL wort. 15 . The method of claim 1 further comprising adding one or more of an ALDC enzyme, a glucoamylase, a maltogenic alpha-amylase, a pullulanase, a catalase or a transglucosidase. 16 . A method for increasing relative foam stability in a beer comprising adding an endoprotease to the beverage, wherein said endoprotease is an enzyme having at least 75, 80, 85, 90, 95, 98, 99 or 100% sequence identity to SEQ ID NO: 1 or an endoprotease active fragment thereof such as a mature protein. 17 . The method of claim 16 wherein the increased relative foam stability is above 100, 101, 102, 103, 104, 105, 106, 107, 108, 109 or 110%. 18 . The method of claim 16 wherein the endoprotease active fragment is a mature protein. 19 . The method of claim 16 wherein the endoprotease is added to a wort. 20 . The method of claim 19 wherein the endoprotease is present in the wort in an amount of 4 to 300 mg protease/hL wort, 10 to 250 mg protease/hL wort, 20 to 200 mg protease/hL wort, 30 to 150 mg protease/hL wort or 40 to 100 mg protease/hL wort. 21 . The method of claim 16 wherein the endoprotease is added to a beer after haze has been formed. 22 . The method of claim 16 wherein the endoprotease is added to a beer before haze has been formed. 23 . The method of claim 16 wherein the beer has an increased relative foam stability and an increased relative haze reduction. 24 . The method of claim 23 wherein the increased relative haze reduction is above 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80% as measured by 90° scattering. 25 . The method of claim 16 further comprising adding one or more of an ALDC enzyme, a glucoamylase, a maltogenic alpha-amylase, a pullulanase, a catalase or a transglucosidase.
