Dextrin Usage And Synthesis
  • Identification testTake about 1 g sample and suspend it in 20ml of water. Add a few drops of iodine test solution (TS-124), which should then appear dark blue color to reddish brown color. The infrared absorption spectrum should be consistent with Figure 10107.
  • ToxicityADI does not make special provisions (FAO/WHO, 2001).
    GRAS (FDA, § 184.1277, 2000);
  • Usage limitFAO/WHO (1984, g/kg): for broth, soup, the value should be according to GMI; cheese (in the cream mixture): 5; the sweetened yogurt and its products after being subject to the heat treatment: 10; mackerel and fish canned: 60 (Only in the packaging material); cold drink: 30.
  • Chemical propertiesIt appears as white, yellow or brown flowing powder. Dextrin of relatively small molecular weight is completely soluble in water to form viscous slurry; dextrin with relatively large molecular mass is not completely soluble in water. ADI is not subject to special provisions (FAO/WHO, 1994).
  • Application
    • It can be used as emulsifying stabilizers and thickeners, adhesives and surface decorators.
    • It can be applied to the pharmaceutical industry, protective adhesives and suspending agents, adhesives. For example, it can be applied to the sizing treatment of paper, textile sizing and ink preparation; it can also be used as a drug excipient and a substitute of the Arabic gum.
  • ProductionIt is obtained from using natural starch originated from cereals or rhizome plants (E.g., corn, sorghum, potato, bamboo, wheat, rice, cassava, sago, etc.) as raw materials which are heated in the presence of suitable food-grade acids and buffers, leading to partial hydrolysis to obtain it. Drying method: apply hydrochloric acid (≤ 0.15%) or orthophosphoric acid (≤ 0.17%) treatment.
    Enzymatic method: take the natural starch of corn, wheat and dried potato as raw material, use 0.15% hydrochloric acid or 0.17% phosphoric acid for heat treatment, and apply starch partial degradation to derive the products.
  • Chemical PropertiesWhite powder
  • Chemical PropertiesDextrin is partially hydrolyzed maize (corn), potato or cassava starch. It is a white, pale yellow or brown-colored powder with a slight characteristic odor.
  • UsesDextrin is a partially hydrolyzed starch formed from the treatment of starch by dry heat, acid, or enzymes. it can be formed from amylose and amylopectin-type starches. they are white or yellow (canary) in color. as compared to unmodified starch, s have increased water solubility, viscosity stability, and reduced paste viscosity. uses include dough improvement and binding.
  • UsesPharmaceutic aid (suspending agent); pharmaceutic aid (viscosity-increasing agent); pharmaceutic aid (tablet binder); pharmaceutic aid (tablet and capsule diluent).
  • Usesdextrin (British gum; starch gum) absorbs moisture. It is also used as a binder to control product viscosity and reduce the density of a cosmetic. This powder is produced from corn starch and modified by means of a bacterial process. It may cause an allergic reaction.
  • Production MethodsDextrin is prepared by the incomplete hydrolysis of starch by heating in the dry state with or without the aid ofsuitable acids and buffers; moisture may be added during heating. The PhEur 6.4 specifies that dextrin is derived from maize(corn),potatoorcassava starch. A specification for cassava is included in the USP32–NF27.
  • DefinitionA polysaccharide sugar produced by the action of amylase enzymes on or the chemical hydrolysis of starch. Dextrins are used as adhesives.
  • Definitiondextrin: An intermediate polysaccharidecompound resulting fromthe hydrolysis of starch to maltose byamylase enzymes.
  • Agricultural UsesDextrin is a group of colloidal products, formed by the hydrolysis of starches with dilute acids or by heating dry starch. The yellow or white powder or granules obtained are soluble in boiling water and insoluble in ether or alcohol. Dextrin is used in adhesives, as thickening agents and in penicillin manufacture.
  • Pharmaceutical ApplicationsDextrin is a dextrose polymer used as an adhesive and stiffening agent for surgical dressings. It is also used as a tablet and capsule diluent; as a binder for tablet granulation; as a sugar-coating ingredient that serves as a plasticizer and adhesive; and as a thickening agent for suspensions.
    Additionally, dextrin has been used as a source of carbohydrate by people with special dietary requirements because it has a low electrolyte content and is free of lactose and sucrose.
    Dextrin is also used in cosmetics.
  • Safety ProfileMdly toxic by intravenous route. When heated to decomposition it emits acrid smoke and irritating fumes.
  • SafetyDextrin is generally regarded as a nontoxic and nonirritant material at the levels employed as an excipient. Larger quantities are used as a dietary supplement without adverse effects, although ingestion of very large quantities may be harmful.
    LD50 (mouse, IV): 0.35g/kg
  • storagePhysical characteristics of dextrin may vary slightly depending on the method of manufacture and on the source material. In aqueous solutions, dextrin molecules tend to aggregate as density, temperature, pH, or other characteristics change. An increase in viscosity is caused by gel at ion or retro gradation as dextrin solutions age,and is particularly noticeable in the less-soluble maize starch dextrins. Dextrin solutions are thixotropic, becoming less viscous when sheared but changing to a soft paste or gel when allowed to stand. However, acids that are present in dextrin as residues from manufacturing can cause further hydrolysis, which results in a gradual thinning of solutions. Residual acid, often found in lesssoluble dextrins such as pyrodextrin, will also cause a reduction in viscosity during dry storage. To eliminate these problems, dextrin manufacturers neutralize dextrins of low solubility with ammonia or sodium carbonate in the cooling vessel.
    The bulk material should be stored in a well-closed container in a cool, dry place.
