Gel strength and viscous synergism index (Iv) were measured and used to analyze their interaction level. Kappa carrageenan had good synergistic effect with cassia, LBG, guar, HPMC and konjac and antagonistic effect with xanthan, alginate, CMC and agar. Only Iota carrageenan in the range of 60:40 with kappa showed neutral effect. A blend of SRC with konjac / LBG can be made for good gel strength whereas konjac / GG for good viscosity. Therefore, SRC can be used in place of refined carrageenan in some food applications.
