The algae is then treated with an acidic solution to help disrupt cell walls, which converts the alginate salts into insoluble alginic acid; a subsequently applied alkaline solution (pH 9-10), usually sodium carbonate, converts it back into water-soluble sodium alginate, which is then precipitated.

In reactors where the process is more complex, water-soluble polysaccharides such as agar, [25] acetan, and sodium alginate [26] are added to prevent clumping or coagulation of bacterial cellulose. The other main environmental factors affecting cellulose production are pH, temperature, and dissolved oxygen.
Seaweed is used in the production of textiles: a water-soluble fiber known as alginate is produced and is used as a holding fiber; when the cloth is finished, the alginate is dissolved, leaving an open area. Rayon is a manufactured fiber derived from plant pulp. [97] Different types of rayon can imitate feel and texture of silk, cotton, wool ...
Sodium alginate; The definition has been expanded, and includes most foods, where the encapsulation of flavors is the most common. [5] The technique of microencapsulation depends on the physical and chemical properties of the material to be encapsulated. [6] Many microcapsules however bear little resemblance to these simple spheres.
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.
[5] [6] MonoSol is one of the companies that develops the water-soluble film used for laundry and dishwasher detergent packs, used by brands including Tide, with roughly US$250 million in annual sales and controlling around 90-percent of the market. [7] Notable brands of these packs include All, Arm & Hammer, Gain, Purex, Persil, Rinso and Tide ...
Bloated food packaging doesn’t always mean the food inside is dangerous to eat, says Zhang. If you live in a high-altitude area, such as Denver, a food package may swell because the air pressure ...
Mucilage mixed with water has been used as a glue, especially for bonding paper items such as labels, postage stamps, and envelope flaps. [7] Differing types and varying strengths of mucilage can also be used for other adhesive applications, including gluing labels to metal cans, wood to china, and leather to pasteboard. [ 8 ]
