soluble hydrolysis products was quantified as glucose according to the procedure presented above.
2.4. Characterization of starch fragments from enzymatic hydrolysis by SE–HPLC/Light Scattering
Supernatants from enzymatic treatments (prior to the treat- ment with amyloglucosidase for glucose quantitation) were filtered through a 0.22 m filter, and 0.2 ml of the filtrate were loaded into a HPLC system (515 pump, Waters Co., Milford, MA, USA); UV detec- tor (Dual Absorbance detector 2487, Waters Co., Milford, MA, USA), connected in series to a differential refrattometer (Optilab T-rEX, Wyatt Co., Santa Barbara, CA, USA) and to a Multi Angle Light Scat- tering instrument (DAWN HELEOS, Wyatt Co., Santa Barbara, CA, USA). Polysaccarides were fractionated on a size-exclusion column
