Sodium Alginate is a seaweed extract used by molecular gastronomy chefs for spherification. It forms a gel in the presence of calcium ions and is a gelling agent that disperses in cold liquids with vigorous agitation. It can create soft or firm gels that remain stable at room temperature and resist heat, and can also be used to produce foams. Sodium alginate is commonly used as a thickener, emulsifier and texture improver.
Suitable for:
Vegans, vegetarians & ovo-lacto vegetarians; non-GMO, gluten-free, non-irradiated
Main Uses:
- Spherification and reverse spherification
- Improving texture
- Thickening solutions and liquids
- Creating soft or firm heat-resistant gels
Directions for use:
The typical dosage is 0.2–1%: gradually add the powder to the liquid solution. Blend or stir until fully dissolved. It dissolves in hot and cold liquids and is insoluble in oils. For spherification, use 0.5–1% sodium alginate by weight of the liquid. To disperse the powder, add it while vigorously agitating the liquid, or mix it with another dry ingredient (such as sugar) before adding it to the liquid. As the powder begins to gel in the presence of calcium, avoid using it in calcium-rich liquids such as milk; use low-calcium bottled water to make the process easier. Add the powder to the liquid or purée and use a syringe to form drops in a calcium bath, where they become caviar pearls. For reverse spherification, reverse the roles of the two ingredients, using sodium alginate in the water bath.
