ABSTRACT:
A novel strain ofLactococcus lactissubspeciescremori(“Ropy 352”) has been identified and isolated. Ropy 352 produces a previously unknown exopolysaccharide (EPS 352) that when expressed or added to milk, imparts highly desirable sensory characteristics to the milk, including making the milk very thick, with a very smooth mouth-feel, and slightly sweet with an obvious “chewable-bite”.
