目的：建立一个基于唾液生化指标的味觉预测系统。方法：本研究包括100名年龄>= 20岁的参与者，没有身体，精神或牙齿残疾。从参与者中收集唾液样本并进行生化分析。使用滴盘法进行味道检查（甜味、咸味、酸味和苦味）。结果：多元回归分析表明，甜味敏感性与唾液生化指标之间存在相关性，甜味敏感性与唾液生化指标之间存在相关性，甜味敏感性与唾液生化指标之间存在相关性（其中较高的分数表示较低的灵敏度）受到各种生化性质的显著影响，其中最强的影响是pH。确定以下预测方程：甜味敏感度= 1.38 +（-0.12 X低pH [1：如果pH < 6.7，0：否则]）+（0.80 X高pH [1：如果pH > 7.3，0：否则]）+（0.04 X Fe [μ g/dL]）。方差分析显示，这些变量对甜味敏感性的影响总体上是显著的（R-2 = 0.74; P < 0.01）。结论：唾液pH值对甜味敏感性的影响最大。这种预测可以用于评估饮食选择的变化，并帮助个人做出健康的食物选择以保持健康。2016 Elsevier Inc.

Objectives: The aim of this study was to establish a prediction system for taste sense according to the biochemical data of saliva. Methods: The present study included 100 participants ages >= 20 y without physical, mental, or dental disabilities. Saliva samples were collected from the participants and subjected to biochemical analyses. Taste examination (sweetness, saltiness, sourness, and bitterness) was performed using the dropped disk method. Correlation analysis and multiple regression analysis were performed between the taste sense properties and biochemical data of saliva.Results: Multiple regression analysis demonstrated that sweetness sensitivity (in which a higher score indicates lower sensitivity) was significantly affected by various biochemical properties, with the strongest influence being pH. The following prediction equation was determined: Sweetness sensitivity = 1.38 + (-0.12 x low pH [1: If pH < 6.7, 0: otherwise]) + (0.80 x high pH [1: If pH > 7.3, 0: otherwise]) + (0.04 x Fe [mu g/dL]). Analysis of variance showed an overall significant effect of these variables on sweetness sensitivity (R-2 = 0.74; P < 0.01).Conclusion: Saliva pH most strongly affects the sweetness sensitivity. This prediction can be used for evaluations of variations in dietary choices and to help individuals make healthy food choices to maintain health. 2016 Elsevier Inc. All rights reserved.
