The Japan Society of Applied Physics is an organization dedicated to the advancement of applied physics in Japan. The Japan Society of Applied Physics (JSAP) acts as a scientific and engineering interface as well as an open forum for academia and industry. JSAP serves as a “conduit” for fundamental principles to be transferred to industry for production and technical applications. Since 1946, when it was founded as an official academic society, JSAP has been one of Japan’s most prominent academic societies. The society’s interests include a wide range of scientific and technical areas, and JSAP continues to pursue cutting-edge and interdisciplinary research. The JSAP accomplishes this by hosting annual conferences, publishing scientific journals, regularly sponsoring science education meetings, symposia, and festivals, and compiling information on cutting-edge technology for the general public.

Calcium alginate is a water-insoluble, gelatinous, cream-colored material generated by mixing aqueous calcium chloride with aqueous sodium alginate. Calcium alginate is also used in plant tissue culture to entrap enzymes and shape artificial seeds.
The term “alginate” generally refers to alginic acid salts, but it may also apply to alginic acid derivatives and alginic acid itself; in some articles, the term “algin” is used instead of alginate. Brown algae’s cell walls contain alginate in the form of calcium, magnesium, and sodium salts of alginic acid. [two]
The seaweed is broken into pieces and stirred with a hot solution of an alkali, normally sodium carbonate, to remove the alginate. The alginate dissolves as sodium alginate over a two-hour span, yielding a very thick slurry. This slurry also includes the non-dissolving parts of the seaweed, mostly cellulose. The insoluble residue in the solution must be washed. Since the solution is too dense (viscous) to process, it must be diluted with a large amount of water. The solution is pushed through a filter cloth in a filter press after it has been diluted. The undissolved residue, on the other hand, is very fine and can easily clog the filter cloth. As a result, a filter aid, such as diatomaceous earth, must be applied before filtration begins; this keeps the majority of the fine particles away from the filter cloth’s surface and encourages filtration. Filter aid, on the other hand, is costly and can add significantly to costs. Some processors push air into the extract as it is diluted with water to minimize the amount of filter aid needed (the extract and diluting water are mixed in an in-line mixer into which air is forced). Air bubbles bind themselves to the residue particles. The diluted extract is left to stand for several hours, during which time the air rises to the surface, carrying the residual particles with it. The frothy mixture of air and residue is pumped to the filter, while the solution is drained from the rim. [two]
Molecular gastronomy (playing with food): “reverse
According to its physical and chemical characterization, sodium alginate has a strong processibility. Alginate scaffolds have been used to prepare soft or hard tissue engineering, but the scaffold’s structure needs to be improved for better skin tissue engineering efficiency. Ionic crosslinking was used to create a highly porous alginate membrane in this research. The best film-forming property was found in alginate with a high molecular weight (Mw=3.0105). As a result, the proper molecular weight should be chosen to improve its efficiency. We produced the honeycomb materials (porosity=92.06%) using freeze-drying technology and pre-freezing at -10°C. Pore structure can be controlled to some degree by changing the pre-freezing temperature. The porosity and pore size of the materials decreased as the sodium alginate dosage was increased, while tensile strength and elongation at break increased. The materials had a strong water absorption ability. The research described above lays the groundwork for the creation of a skin tissue engineering scaffold.

Sodium alginate is a natural gelling agent derived from brown algae cell walls. When it comes into contact with calcium, though, it gels. Other than spherification, sodium alginate can be used for thickening, general gelling, and foaming. Sodium alginate can be used in a variety of commercial items, including ice cream and the pimento part of stuffed cocktail olives, whether you realize it or not.
To make spheres with sodium alginate, there are two methods. The first is direct spherification, which involves blending sodium alginate into a flavorful liquid and then spooning it into a calcium lactate or calcium chloride bath. The second method is reverse spherification, which involves adding calcium to a flavorful liquid and then spooning the liquid into a sodium alginate bath.
In non-acidic mixtures, sodium alginate performs best. If you’re using it in an acidic recipe, you can normally adjust the pH with sodium citrate before adding the sodium alginate. If you want to gel a thicker material, such as a puree, thin it down with water until it reaches a more liquid consistency.
