摘要：

The viscoelastic properties of sweetpotato (SP) puree restructured with alginate were determined and compared with those of non-restructured SP puree. Results from oscillatory shear experiments showed that both purees behaved like a gel with the storage modulus (G') predominant over the loss modulus (G"). The addition of a calcium/alginate complex increased the firmness of SP puree. Gel strength of both restructured and non-restructured puree was highest at room temperature (25 degreesC).
