The effects of differentgel time and aqueous solution with different pH (pH 2～11) on thegel properties of sodium alginate were studied. The results showed that thegel time of alginategel had agreat effect on thegel strength. With the increase ofgel time, thegel strength of sodium alginategradually increased, and tended to be stable and tastedgood after 2h. When the pH of sodium alginate aqueous solution was 6～8, the viscosity and pH of sodium alginategel solution was relatively stable, and the sodium alginategel products had biggel strength,good taste and flexible, and a little water exudation with high sensory evaluation easy to be accepted. Comprehensive analysis showed that the aqueous solution with pH value 6～8, the prepared sodium alginategel had good taste, a littlegel water exudation andgood quality.
