先前的工作表明，测量液体饮食的摄入速率，而不是简单的体积，揭示了摄入行为的重要特征，这有助于解释为什么摄入特定体积的液体。这项研究是该工作的延伸，以各种不同的测试解决方案。在这项研究中，糖精，两种不同浓度的葡萄糖和蔗糖及其混合物与糖精和七种不同浓度的麦芽糖的摄入率进行了测量。通过最小二乘法将速率函数拟合为线性函数，以确定截距和斜率常数。这两个参数如何随测试溶液的浓度和组成变化的分析使用不同的测试溶液证实了先前报道的结论，即初始摄取速率（截距）测量适口性，并且斜率常数是负反馈饱腹感信号的发展速率的量度。
Previous work has shown that measuring the rate of ingestion of liquid diets, rather than simply volume, reveals important features of ingestive behavior which can help to explain why a particular volume of a liquid is ingested. This study is an extension of that work to a variety of different test solutions. In this study the rate of ingestion of saccharin, two different concentrations of glucose and sucrose and their mixtures with saccharin and seven different concentrations of maltose were measured. The rate functions were fit by the least-squares method to a linear function to determine the intercepts and slope constants. Analysis of how these two parameters changed with the concentration and composition of the test solutions confirms, using different test solutions, a previously reported conclusion that the initial rate of ingestion (the intercept) measures palatability and that the slope constant is a measure of the rate of development of a negative feedback satiety signal.
