Abstract:

An MCR101-type rheometer was used to study the effects of various kinds and amounts of hydrocolloid on rheological properties of horse mackerel surimi. The results showed that the single addition of curdlan, tamarind gum, konjac, carragineen, agar and CMC was able to significantly increase the peak of storage modulus (G'm) and storage modulus of 95 ℃ (G'95) during heating and gelation rate (k) and storage modulus of 20 ℃ (G'20) during chilling. Guar gum and alginate both showed little effect on the dynamic rheological properties of horse mackerel surimi while xanthan both gum and pectin exhibited a negative effect on the above dynamic rheological properties. There was a positive correlation between k and G'20, that is, the higher the gelation rate, the stronger the gel strength of surimi gel.

Key words: hydrocolloids, horse makerel, surimi, gel, rheological properties
