Table 3. Molecular weight parameters of commercial gum Arabic samples determined by GPC-MALLS. Weight average molecular weight (Mw) for the whole gum is given in column 2. % mass means the recovered mass which is calculated using a dn/dc value of 0.141, Rg is the RMSS-radius of gyration. Mwt processed as two peaks means that the high molecular weight peak was processed separately and the remainder of the gum processed as the second peak. It thus contains more than one component. P is a measure of the polydispersity (Mw/Mn)
