INTERACTION OF SEMI-REFINED CARRAGEENAN (E407A) WITH NANO QUANTA OF SOME FOOD HYDROCOLLOIDS AND THEIR PHYSIOCHEMICAL, FUNCTIONAL AND RHEOLOGICAL PROPERTIES

摘要

Interaction of semi-refined carrageenan with other food hydrocolloids in different ratio and their rheological, physicochemical and some functional characteristics were evaluated in the present study. 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.
