Alginate was discovered by British chemical scientist E. C. C. Stanford in 1881, and he patented an extraction process for it in the same year. [4] The alginate was extracted, in the original patent, by first soaking the algae in water or diluted acid, then extracting the alginate by soaking it in sodium carbonate , and finally precipitating ...
Calcium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture.
In enzymology, an alginate synthase (EC 2.4.1.33) is an enzyme that catalyzes the chemical reaction GDP-D-mannuronate + (alginate)n ⇌ {\displaystyle \rightleftharpoons } GDP + (alginate)n + 1 Thus, the two substrates of this enzyme are GDP-D-mannuronate and (alginate)n , whereas its two products are GDP and (alginate)n+1 .

A more recent technique is frozen reverse spherification, which involves pre-freezing spheres containing calcium lactate gluconate and then submerging them in the sodium alginate bath. Basic and reverse spherification methods give much the same result: a sphere of liquid held by a thin gel membrane, texturally similar to roe.

Extraction Profile for Different Types of Extraction. The extraction curve of % recovery against time can be used to elucidate the type of extraction occurring. Figure 4(a) shows a typical diffusion controlled curve. The extraction is initially rapid, until the concentration at the surface drops to zero, and the rate then becomes much slower.
