    Notes:
    High-pressure-induced gelation of ovalbumin, egg yolk and soy protein was studied by pressurization up to 500 MPa for 30 min at -20 to 50°C; hardness, cohesiveness and gumminess of the gels were compared to those of gels obtained by heating at 100°C for 10 min. In the range -5 to 50°C, ovalbumin gelation showed a minimum at 25°C at all pressures applied. Operating at low temperatures allowed a reduction in pressure required to provide rather hard gels. With egg yolk and soy protein, gelation effectiveness progressively and continuously decreased with decreasing temperatures; the decrease was sharper with egg yolk.

    summary  At the oral stage of swallowing, the tongue plays a major role and proper tongue performance is necessary to form the bolus and transfer it to the pharynx. For the present study we built a prototype device for safe and handy objective estimation of tongue motion and coordination with laryngeal elevation at swallowing. The device records tongue pressure by means of two strain gauge pressure transducers aligned 20 mm apart on a brass strap placed along the palatal midline. Laryngeal vibration is recorded with piezo-electric acceleration transducers. Time differences between pressure onset at the anterior and posterior transducers and the first spike from laryngeal vibration are measured. Ten healthy subjects were asked five times to swallow 5 mL of water. Pressure onset at the anterior transducer preceded posterior pressure by 294 ± 164 ms. Given the distance between the transducers, the tongue contracted (squeezed) at a speed of 93 ± 60 mm s−1. Laryngeal vibration occurred 671 ± 175 ms after the onset of anterior pressure. There was considerable variation in these parameters between subjects. Though the data is limited, the device successfully and easily revealed certain aspects of tongue motion and coordination with laryngeal elevation.

    Notes:
    In managing elderly people's quality of life, dysphagia is a critical problem because of its presumable relation to pneumonia. In the oral stage of swallowing, the tongue involves profoundly and its proper performance is necessary for bolus forming and transferring to the pharynx. In this regard, informative videofluorography, however, requires special facilities and inevitable exposure to radiation. For the present study we prototyped a device for a safe and handy objective estimation of tongue motion and its coordination with laryngeal elevation at swallowing.Ten healthy subjects were asked five times to swallow 5 mL of water. The tongue pressure was recorded by means of two strain gauge pressure transducers aligned in 20 mm distance on a brass strap placed along the palatal midline. Laryngeal vibration was recorded with piezo-electric acceleration transducer. Time difference between each pressure onset of the anteriorly/posteriorly located transducers and impulsive output of laryngeal vibration were measured.Pressure onset of the anteriorly located transducer preceded posterior one for 294 ± 164 ms. Considering the distance of transducers, tongue squeezed at 93 ± 60 mm s−1 speed. Laryngeal vibration occurred 671 ± 175 ms after the anterior pressure onset. There was a large variation in these parameters between subjects. The total recording time for each subject was 〈10 min. Although the information is limited, the developed device could handily describe some aspects of tongue motion and its coordination with laryngeal elevation.
