本研究的目的是考察不同厚度的增稠剂对食品团粒中颗粒大小的影响。在医疗和护理中，增稠剂被用来使吞咽困难患者的食物安全。然而，增稠剂对添加到食物中的影响，特别是在吞咽过程中的影响，仍然不清楚。20名健康志愿者的团注颗粒被拍摄下来，并使用数字图像来估计其中的颗粒大小。用不同浓度的增稠剂对8个试验样品进行了测试：6个等级的加有生胡萝卜的增稠胡萝卜汁、生胡萝卜加香蕉，以及只加生胡萝卜。计算吞咽前颗粒均匀度指数(HI)和颗粒大小指数(SI)。还测量了测试样品的液体部分的粘度。测试样本的咀嚼周期数没有显著差异。然而，SI和HI在不同测试样本之间存在显著差异：SI和HI的绝对值随着测试样本厚度的增加而上升。测试样品的液体部分的粘度也随着厚度的增加而增加。食物厚度的不同对吞咽前的丸剂颗粒大小有影响。
The purpose of this study was to examine the influence of thickeners with different levels of thickness on the sizes of particles in food boluses. In medical and nursing care, thickeners are used to make food safe for patients with dysphagia. However, the effect of thickeners on the foods they are added to, especially during swallowing, is still unclear. The bolus particles of 20 healthy volunteers were photographed, and the digital images were used to estimate the sizes of particles in them. Eight test samples with thickeners with different levels of thickness were tested: six grades of thickened carrot juice with raw carrots in it, raw carrot with banana, and raw carrot alone. The particle homogeneity index (HI) and particle size index (SI) just before swallowing were calculated. The viscosities of the liquid part of the test samples were also measured. The number of mastication cycles across the test samples was not significantly different. However, significant differences were found in SI and HI across the test samples: the absolute values of SI and HI tended to rise as the thickness of the test sample increased. The viscosity of the liquid part of the test sample also increased as the thickness increased. The differences in the thickness of food had an influence on the bolus particle sizes just before swallowing.
