Bionic design of the oral swallowing in vitro and its application in the dysphagia

Based on the bionic swallowing device in vitro of similar human-tongue motion during swallowing, the average correlation coefficients between the tongue trajectories of patients at five swallowing grades and those of the BSD were 0.87, proving its effectiveness and potential application. Furthermore, the corn-paste experiments of the bionic swallowing device showed that the dysphagia at five swallowing grades s could be a suitable choice for certain food concentration.

A method for evaluating time-resolved rheological functionalities of fluid foods

Ultrasonic spinning rheometry described time variation of the instantaneous viscosity curves for typical thickener solutions with alpha-amylase as a digestive enzyme. A K-n diagram was constructed from the obtained viscosity curves for quantitatively characterizing time-resolved rheological functionalities of fluid foods.

The surface mechanics of cooked rice as influenced by gastric fluids measured using a micro texture analyzer

This article introduces a micro texture analyzer in terms of its origin, key features, reliability and data analysis of texture profile. This device was employed to explore the texture characteristics of the surface of an individual steamed rice (SR) and fried rice (FR) grain as influenced by different gastric digestion environments in vitro. Similar mechanical behaviors were shown, but the hardness and elastic modulus of FR were decreased less than that of SR during in vitro digestion in the same digestion condition.

Texture and viscoelastic characteristics of silver carp (Hypophthalmichthys molitrix) surimi affected by combination of washing regimes and hydrogen peroxide

This study investigated the texture and rheological characteristics of silver carp surimi after being exposed to different concentrations of H2O2 and mince:water ratios during different washing cycles. Finally, it was revealed that there is possible texture damage of fish mince after being exposed to H2O2 as it results in a weaker surimi gel compared to the one prepared by the conventional washing method.

Effects of variety, early harvest, and germination on pasting properties and cooked grain texture of brown rice

Early harvest had a greater effect on reducing the hardness of cooked whole grain while germination substantially reduced viscosities of flour paste. The softer texture of brown rice, about 10 N (32%) lower, could be achieved by germination and a further 5 N (46%) by harvesting early. Desired characteristics in rice flour as ingredients in the food industry and of whole grain for direct consumption can be achieved by selecting a suitable variety and by harvesting the grain early or germination.

Mechanical properties of gellan gum beads prepared with potassium or calcium ions

Beads of low acyl gellan gum were produced using extrusion technique (dripping) followed by an ionotropic gelation step with calcium or potassium chloride. Gellan and salts concentrations suitable to gel beads formation were determined and mechanical properties of gellan beads were measured by uniaxial compression. Maximum force or force at failure was mainly dependent on the type and salt concentration. Young modulus, determined using Hertz approach, showed values between 445 and 840 kPa depending on polysaccharide concentration and cation type added.

Stability and rheology of plant-derived hydrocolloid–mucin mixtures

This study studied mixtures of pectin and mucin at a range of pH values, as to obtain basic data on the phase behavior, self-assembly and rheology of these systems in relation to the oral and gastrointestinal processing of relevant foods.
