Commercial thickeners used by patients with dysphagia: Rheological and structural behaviour in different food matrices
2015
In order to achieve a safe swallowing in patients with dysphagia, liquids must be thickened. In this work, two commercial starch based thickeners dissolved inwater,whole milk, apple juice and tomato juice were studied. The thickeners were Resource®, composed of modified maize starch and Nutilis®, composed of modified maize starch and gums. They were formulated at two different concentrations corresponding to nectar- and pudding-like consistencies. Influence of composition, concentration and food matrix on rheological properties and structure of the resulting pastes were analysed. Viscoelastic measurements and microscopic observations of the thickeners dissolved in water revealed structural …
Modelling of Starch Gelatinisation and Liquefaction with the Enzyme Liquozyme
2011
In this paper the influence of the enzyme Liquozyme Supra concentration (0.4-1.2 kg/t dry substance DS) and gelatinisation time (3-11 min.) on the liquefied starch quality is investigated. The composition in sugars with different Degrees of Polymerisation (DP) as DP1 (glucose), DP2 (maltose), DP3 (maltotriose), DP4 (maltotetrose) and oligosaccharides with DP≥5 is analysed by using HPLC with RI detector. The products obtained have different DP, the main components being oligosaccharides with DP≥5, followed by small amount of DP3+DP4 and much smaller concentrations of DP1; no DP2 is produced by this enzyme. Two quality criteria: the percent of oligosaccharides with DP≥5 and the percent of DP1…
