LACTOCOCCUS LACTIS STRAINS FOR PRODUCING BIOACTIVE PEPTIDES HAVING ANTI-HYPERTENSIVE AND CHOLESTEROL-LOWERING EFFECTS

摘要

New Lactococcus lactis strains, NRRL B-50571 and NRRL B-50572, and a bacterial preparation containing the same, have the ability to produce bioactive peptides that reduce blood pressure, lower LDL-cholesterol (bad cholesterol) and present antioxidant properties for better cardiovascular health. These biologically active peptides may be produced within the food for the production of a food product, such as a functional food, or they may be produced from protein sources and subsequently added to a food as part of the formulation or as part of a food supplement or a pharmaceutical preparation.
