Abstract

Abstract:

In order to reveal the influence of ultrasonic treatment on the gel properties of starch pastes, the gel properties of potato starch paste with variable concentration were investigated using a texture analyzer in different ultrasonic treatment conditions. Then, the microstructure of the potato starch paste after the ultrasonic treatment was observed by means of SEM. The results show that the ultrasonic treatment greatly affects the gel properties of potato starch, and that the gel strength decreases with the prolonging of ultrasonic treatment time and with the increase of ultrasonic intensity, the decreasing degree being positively linear with the concentration of starch paste. Moreover, it is demonstrated that the degradation of gel properties mainly results from the variation of paste mierostructure caused by ultrasonic treatment, concretely, after the ultrasonic treatment, the microstructure of starch paste changes from a stronger composite network to a loosen and group-gathering one.

Key words: ultrasonic, potato starch paste, gel strength, microstructure
