In this study, we present an enzymatic fingerprinting method for the characterization of isomalto/malto-polysaccharides (IMMPs). IMMPs are produced by the modification of starch with the 4,6-α-glucanotransferase (GTFB) enzyme and consist of α-(1→

Starch-based isomalto/malto-polysaccharides (IMMPs) are soluble dietary fibres produced by the incubation of α-(1 → 4) linked glucans with the 4,6-α-glucanotransferase (GTFB) enzyme. In this study, we investigated the reaction dynamics of the GTF

Resistant starch type 3 (RS-3) holds great potential as a prebiotic by supporting gut microbiota following intestinal digestion. However the factors influencing the digestibility of RS-3 are largely unknown. This research aims to reveal how crystal t

Isomalto/malto-polysaccharide structure in relation to the structural properties of starch substrates

Isomalto/malto-polysaccharides (IMMPs) are soluble dietary fibres produced by the enzymatic modification of starch with 4,6-α-glucanotransferase (GTFB). The structure, size, and linkage distribution of these IMMPs has remained largely unknown, since

Biobased feedstocks offer a potent source of building blocks for biobased products. However, these feedstocks (e.g. starch, cellulose) are generally highly polydisperse in molecular weight. To study the effect of polydispersity on conversion kinetics

Dietary fibers are at the forefront of nutritional research because they positively contribute to human health. Much of our processed foods contain, however, only small quantities of dietary fiber, because their addition often negatively affects the
