Calcium ions react instantly with alginate on the surface of proplets or streams of alginate solution to form a gel. Following this initial reaction, calcium ions diffuse inward.

Internal Setting

Solution Content

 

  • Sodium Alginate
  • Slowly dissolving calcium salt
  • Chelating agent
  • Ionizing agent

Heat Stability

Gel Strength and M/G Ratio

High M alginates form resilient and elastic gels, while high G alginates form firm and brittle gels. The desired gel strength is obtained by high G and high M alginates

Syneresis and M/G Ratio

M/G Ratio Syneresis
High G 0.6 5.2%
Standard 1.3 3.8%
High M 2.2 2.0%
