The current study was therefore aimed at examining the
chemical and physical characteristic and antioxidant activities of
the EPS synthesised by Tibetan kefir grains during milk fermentation, as well as examining their ability to prevent the oxidative
damage of proteins. In the study, a Tibetan kefir grain that has been
widely used and transformed around China was selected due to its
extensive influence in our daily life. This work provides some
fundamental information that could be useful as a guide to practical
applications of this EPS.
