What is Alginic Acid Gerda?

Alginic Acid Gerda is a viscous organic acid, also known as alginic acid and alginic acid. The product is white to light yellow-brown powder. The average molecular weight is about 240,000. Melting point>300℃. Slightly soluble in hot water, the viscosity of its aqueous solution is 4 times higher than that of starch, insoluble in cold water and organic solvents, and slowly soluble in alkaline solution. Odorless. It is widely found in the cell walls of hundreds of species of brown algae such as macroalgae, kelp, kelp, fucus and sargassum, among which the content of kelpaceae algae is more (about 20% on average), and most of them exist in the form of calcium salts and magnesium salts .

Alginic Acid Gerda is a linear block polyuronic acid consisting of a homopolymeric α-L-mannuronic acid block, a homopolymeric β-D-mannuronic acid block and These two uronic acid cross-polymerization blocks are connected by 1,4-glycosidic bonds. It exists in the cell walls of many marine brown algae in the form of calcium, magnesium, sodium, potassium, and strontium salts. Industrially, it consists of macroalgae, kelp, palmate kelp, sugar kelp, kelp, wedge-based kelp (L.ochotensis), narrow-leaf kelp, Ascophyllumrodosum, staghorn algae, Fucusvesiculosus , Nitrogenodon serrata, sea algae, kelp and algae (Alaria), etc. are extracted. The general extraction method is as follows: after the raw seaweed is washed, it is digested with alkali to form soluble alkali metal salts of alginic acid, and the alginic acid is precipitated by filtration and acid addition. Alginic acid can also be converted into sodium, potassium, ammonium, calcium salts or other organic derivatives, collectively known as algin (aglin). Commercial alginate mainly refers to sodium alginate.

Free alginic acid is a white solid. Insoluble in cold water, slightly soluble in hot water. Strong acidity and acid resistance, but easily decomposed by hot alkali. Decarboxylation occurs with concentrated hydrochloric acid. It has a certain selective adsorption effect on metal ions, especially Fe(II) ions. Its alkali metal salts and ammonium salts dissolve in water to form a viscous liquid, but are not easy to form gels. Converts to insoluble alginic acid gels or precipitates below pH 3. Add polyvalent metal ions (such as calcium chloride) to easily gel. Sodium salt is slightly yellow powder, insoluble in organic solvent, [a]D-139°. Algin is widely used in food, textile printing and dyeing, paper making, medicine, leather, cosmetics, rubber, paint and water treatment industries.

Alginic Acid Gerda is mainly used as a raw material for salts such as sodium alginic and in the manufacture of medicines such as capstomata. Also used as excipients, binders and stabilizers for tablets. Commonly used as thickener and emulsifier in food and cosmetics.

Alginic Acid Gerda Application

Recently, brand-new plant foods consisting of Alginic Acid Gerd have actually emerged one after another. In international nations, Alginic Acid Gerd has actually been utilized in agriculture extremely early. Algaes made use of as plant foods are normally huge economical algae, such as macroalgae, Ascophyllum nodosum, and also sea cysts. The growth of seaweed plant food has actually experienced 3 phases: rotten seaweed → algae ash (powder) → algae remove. The core substance in seaweed plant food is pure all-natural seaweed remove. The major raw material is chosen from natural algae. After special biochemical procedure, the essence of seaweed is extracted, which greatly retains all-natural energetic elements, and also consists of a huge amount of non-nitrogenous raw material, More than 40 type of mineral aspects and also abundant vitamins such as potassium, calcium, magnesium, zinc, iodine, etc, which are matchless to land plants, especially consist of algae polysaccharides, alginic acid, extremely unsaturated fats as well as a range of natural plants that are special to algae. Growth regulatory authorities, with high biological task, can stimulate the manufacturing of non-specific active consider plants and also manage the balance of endogenous hormones.

After special treatment, the active elements in seaweed are in an active state that is easily absorbed by plants. They enter the plant body 2-3 hrs after use, and have a quick absorption and transmission rate. Algae has all-natural plant growth regulatory authorities such as: auxins, cytokinins and gibberellins, and so on, which have high organic task, as well as the proportions of various compounds are similar to those of earthbound plants.

Alginic acid can lower the surface tension of water, develop a movie externally of plants, boost the call area, and make it easier for water-soluble materials to get in plant cells through the cell membrane layer on the surface of stems and also leaves, so that plants can soak up the nutrients in the seaweed extract most properly. For that reason, if algae fluid plant food is made use of in combination with pesticides, fungicides as well as chemical fertilizers, the impact is better, the splashing price can be minimized, and it has a collaborating result on chemicals as well as chemical fertilizers. It has actually been reported abroad that the natural anti-biotics consisted of in Alginic Acid Gerd have antiviral effects. The raw material of seaweed fertilizer is picked from all-natural seaweed, which has great affinity with terrestrial plants, is non-toxic and also safe to humans and also animals, and also has no air pollution to the atmosphere. It has advantages unparalleled by any other fertilizer.

Alginic Acid Gerd can directly add organic matter to the dirt or via plants, trigger different valuable microbes in the soil, and also can act as a catalyst in the cycle of plant as well as microbial metabolites, boosting the biological efficiency of the soil. Metabolites of dirt microbes can supply more nutrients for plants.

Alginic Acid Gerd is an all-natural biologic that works in consistency with plant and also dirt ecological communities. The all-natural compounds it contains, such as sodium alginate, are natural soil conditioners, which can promote the formation of soil aggregate framework, improve the pore area inside the soil, collaborate the percentage of strong, liquid and gas in the dirt, as well as bring back the dirt due to overburden and also chemical The natural colloid equilibrium shed by contamination boosts dirt biological activity, advertises the release of readily available nutrients, is conducive to root growth, and also boosts the stress and anxiety resistance of plants.

Alginic Acid Gerd Production Method

Alginic acid is widely present in the cell walls of hundreds of brown algae such as macroalgae, kelp, fucus and sargassum, and most of them exist in the form of calcium and magnesium salts. The method for preparing alginic acid is to extract the above-mentioned algae with sodium carbonate aqueous solution, and then purify with hydrochloric acid or calcium chloride. The technological process is as follows: adding sodium carbonate to the kelp after extraction of iodine, heating to 60-80° C., stirring for 2 hours, so that calcium alginate in the kelp forms sodium salt and dissolves in water. Add a small amount of formaldehyde to fix the pigment to improve the color of the finished product. Divide the dipping liquid and dilute it with water. Coarsely filter through a 30 mesh sieve. And the slag is removed by the emulsification floating method. Then pass through a 100-mesh sieve for fine filtration to obtain a coarse filtrate. Add hydrochloric acid to the fine filtrate to pH=2, so that sodium alginate is freed to form alginic acid and precipitate in gel form, and 5% calcium chloride is added to promote dehydration of the gel. Press filter with a press to make the water content of the alginic acid gel below 75%.
