Sometimes, however, two much calcium can be present in the mixtures involved, usually due to naturally-occurring calcium in tap water. index = parts[0]; } index = -1; If the liquid to be used for hydration contains natural calcium ions, it is necessary to use a sequestrant like sodium citrate to bind those ions and enable proper hydration. For example, according to Modernist Cuisine, a 0.3% LA Gellan solution solution with hard water requires 0.2% sodium citrate, while with bottled drinking water it requires only 0.12%. Join our community of over 240,000 fans and master the latest molecular gastronomy techniques. Add 24.096 g of Sodium Citrate dihydrate to the solution.
