Creep property is an important quality index of fresh tomatoes. Creep property of intact tomatoes stored at normal temperature was studied using Instron universal machine. The changes of four variables of creep property, as well as compress modulus E, firmness F<sub>i</sub>, sugar content and pH value, etc, were analyzed. It was concluded that viscoelastic coefficient of creep property and compress index decreased in the beginning, then increased slowly, reached the highest values on the ninth day, and descended rapidly. Meanwhile, the results indicated that the sugar content and pH value of tomatoes increased slowly during storage at normal temperature.
