Serial studies were carried out on six healthy volunteers (19-24 years) to investigate the effect of meal temperature [either 4 degrees C (cold), 37 degrees C (control) or 50 degrees C (warm)] on the rate of gastric emptying of a radiolabelled isosmotic drink of orange juice. The mean maximum intragastric temperature occurred 60 seconds after the onset of ingestion of the warm drink and reached 43.0 degrees C (0.4) mean (SD) while the mean minimum intragastric temperature occurred 45 seconds after the onset of ingestion of the cold drink and reached 21.2 degrees C (1.9). Intragastric temperature then returned to body temperature within 20-30 minutes of ingestion of the warm and cold drinks. Warm and cold drinks appeared to empty from the stomach more slowly than the control drink. The initial rate of gastric emptying of the cold drink was significantly slower than the control drink (p less than 0.05) and the difference in emptying rates between cold and control drinks were significantly correlated with the differences in intragastric temperatures (p less than 0.01). The difference in the initial emptying rates between warm and control drinks were not statistically significant.
对6名健康志愿者（19 - 24岁）进行了系列研究，以调查进餐温度[4℃（冷）、37℃（对照）或50℃（热）]对放射性标记的等渗橙汁饮料胃排空速率的影响。热饮摄入开始后60秒出现平均最大胃内温度，达到43.0℃（标准差0.4），而冷饮摄入开始后45秒出现平均最小胃内温度，达到21.2℃（标准差1.9）。摄入热饮和冷饮后，胃内温度在20 - 30分钟内恢复到体温。热饮和冷饮从胃中排空的速度似乎比对照饮料慢。冷饮的初始胃排空速率明显慢于对照饮料（p < 0.05），冷饮与对照饮料之间的排空速率差异与胃内温度差异显著相关（p < 0.01）。热饮与对照饮料之间的初始排空速率差异无统计学意义。
