The molecular mass of heteropolysaccharides may range from 4.0 * [10.sup.4] and 6.0 * [10.sup.6] [27]; Streptococcus thermophilus SY2 produced two EPS fraction of 2 * [10.sup.6] and 5 * [10.sup.4] [26].
According to this observation, it is anticipated that the hydrophobic tails of two surfactants molecules are partially encapsulated into the cavity of a [beta]-CD molecule forming a 2:1 inclusion complex; after which the supramolecular system (SAP) is formed by self-assembling through nonbonding interactions between the S: [beta]-CD inclusion complexes and the branch chains of the heteropolysaccharide (xanthan gum backbones).
