(author), Priebe, M.G. (author)Background: The consumption of products rich in cereal fiber and with a low glycemic index is implicated in a lower risk of metabolic diseases. Previously, we showed that the consumption of fiber-rich pasta compared with bread resulted in a lower rate of appearance of exogenous glucose and a lower glucose clearance rate quantified with a dual...article 2017

Ahmadi-Abhari, S. (author), Woortman, A.J.J. (author), Hamer, R.J. (author), Oudhuis, A.A.C.M. (author), Loos, K. (author)Starch is an omnipresent constituent which is used for its nutritional and structuring properties. Recently concerns have been raised since starch is a source of readily available glucose which is tightly correlated with diabetes type II and obesity. For this reason, the possibilities for modulating the digestibility of starch while preserving...article 2013

(author)Microbacterium aurum strain B8.A was isolated from the sludge of a potato starch-processing factory on the basis of its ability to use granular starch as carbon- and energy source. Extracellular enzymes hydrolyzing granular starch were detected in the growth medium of M. aurum B8.A, while the type strain M. aurum DSMZ 8600 produced very little...article 2012

(author), TNO Kwaliteit van Leven (author)Chemical derivatization is often applied to improve polysaccharide functionality. Primary hydroxyl groups in starch can, for example, be oxidized to aldehydes by using a 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-mediated reaction. The major part of the aldehydo groups is subsequently converted to carboxyl groups by NaOCl. The exact structure...article 2010

(author), TNO Kwaliteit van Leven (author)Consumer appreciation of brittle cellular foods, like bread crusts, depends on textural properties such as crispness. This crispy character is lost above a certain water activity. It is not known what exactly is happening in these crusts when water enters. So is it unclear whether it is the change in the starch or the gluten that initiates the...article 2010

Steeneken, P.A.M. (author), Helmens, H.J. (author), TNO Kwaliteit van Leven (author)A laboratory-scale process is presented for the manufacture of starch and gluten from wheat. Main feature of this process is that whole wheat kernels are crushed dry between smooth rolls prior to wet disintegration in excess water in such way that gluten formation is prevented and fibres can be removed by sieving. Centrifugation of the endosperm...article 2009

Fischer, H.R. (author), de Vlieger, J.J. (author), TNO Industrie en Techniek (author), IenT (author)The worldwide production of synthetic plastics is still growing. Out of the total plastics production approximately 40% is used in packaging. This short-term application will cause a global environmental problem because these plastics are not compostable and are difficult to recycle.

(author), TNO Kwaliteit van Leven (author)When aqueous potato starch suspensions were heated into the solution state and cooled, spreadable particle gels were obtained with a spherulite morphology and a cream-like texture. This so-called superheated starch (SHS) exhibits more effective gelling properties than maltodextrin, which is currently applied as a fat mimetic. In addition, a gel...article 2009
