Protein lipase inhibitor for flour and dough
View Patent ↗The present invention relates to the isolation of and characterization of a novel lipase inhibitor and its effect on different lipases. The present invention also relates to the use of a lipase inhibitor as a screen for lipases. The present invention also relates to the use of the inhibitor and/or lipases identified by a lipase inhibitor in food and/or feed technologies.
1. An isolated lipase inhibitor comprising:
(i) the amino acid sequence of SEQ ID No. 7; or
(ii) an amino acid sequence having at least 90% amino acid sequence identity to SEQ ID No. 7, wherein said amino acid sequence functions as a lipase inhibitor.
2. A lipase inhibitor according to claim 1 , wherein said lipase inhibitor has a molecular weight of about 29 kDa, as determined by SDS PAGE.
3. A lipase inhibitor according to claim 1 which is a polypeptide obtainable from a cereal.
4. A lipase inhibitor according to claim 1 which is a polypeptide obtainable from flour.
5. A foodstuff or feed comprising an isolated lipase inhibitor wherein the lipase inhibitor comprises:
(i) the amino acid sequence of SEQ ID No. 7; or
(ii) an amino acid sequence having at least 90% amino acid sequence identity to SEQ ID No. 7, wherein said amino acid sequence functions as a lipase inhibitor.
6. The lipase inhibitor according to claim 1 , wherein the amino acid sequence has at least 95% sequence identity to SEQ ID No. 7.
7. The foodstuff or feed according to claim 5 , wherein the amino acid sequence has at least 95% sequence identity to SEQ ID No. 7.
8. The lipase inhibitor according to claim 1 , wherein the amino acid sequence has at least 98% sequence identity to SEQ ID No. 7.
9. The foodstuff or feed according to claim 5 , wherein the amino acid sequence has at least 98% sequence identity to SEQ ID No. 7.
