Abstract:

Gel texture properties of water caltrop starch paste from Xichang, Sichuan province were investigated using a TAXT2i texture analyzer. A significant change in gel texture properties of water caltrop starch paste formed by different concentrations was occurred under various ultrasonic treatment conditions. Hardness, gumminess, chewiness, elasticity, cohesiveness and recoverability of gel texture properties exhibited a decreasing tendency as the increases of time and intensity of ultrasonic treatment. However, the decreasing tendency of gel texture properties was attenuated with an increase of water caltrop starch paste concentration.

Key words: ultrasonic treatment, water caltrop starch, gel, texture property
