The EPS produced by S. thermophilus in skim milk was extracted and sulphonated.
- class="label">•
The EPS was composed of hexasaccharide repeating unit of glucose and galactose.
- class="label">•
More uniform microstructure was obtained after sulphonation of the EPS.
- class="label">•
Sulphonation lowered the degradation temperature of the EPS.
