Steeneken, P.A.M. (author), Woortman, A.J.J. (author), TNO Kwaliteit van Leven (author)The occurrence of surface effects in the acetylation of granular potato starch with acetic anhydride to degrees of substitution 0.04-0.2 was studied by two different approaches. The first approach involved the fractionation of granular starch acetates into five different size classes and analysis of their acetate content. Alternatively, two...article 2008

(author), TNO Kwaliteit van Leven (author)The effect of the granule structure on the methylation of starch was investigated by comparing the substitution patterns of potato starch methylated in granular suspension and in solution to DS 0.3. Substitution patterns were analyzed by successive digestion with α-amylase and amyloglucosidase, fractionation of the resulting malto...article 2008
