Dextrin - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| properties | White amorphous powder, odorless, slightly sweet. |
| Use | White dextrin is used in the pharmaceutical industry, protective glue and suspension agent, adhesive, such as paper sizing, textile sizing, ink preparation, etc.; Also used as drug excipients and gum arabic substitutes, etc. as emulsion stabilizers and thickeners. is a good adhesive, such as paper sizing, textile sizing, ink preparation, also used as drug excipients and gum arabic substitutes, such as thickener; stabilizer; Adhesive, surface decoration agent. used in pharmaceutical industry, protective glue and suspending agent, adhesive, such as paper sizing, textile sizing, ink preparation, etc; it is also used as a drug excipient and a substitute for gum arabic, etc. colorimetric determination of the total content of organic compounds (organic compounds oxidized by potassium dichromate in sulfuric acid solution), tin, zinc, lead, calcium, magnesium masking agent, as a protective colloid. Pharmaceutical. |
| Application | dextrin is widely used as an adhesive in medicine, food, paper making, casting, wallpaper, labels, stamps, adhesive tape paper, etc. When used as a tablet Binder, rapid drying, rapid dispersion, rapid adhesion and rewet solubility are required, and white dextrin or low viscosity yellow dextrin products can be selected. In the label, stamp adhesive, the need for high viscosity, the formation of a film with strong toughness, suitable for white dextrin or British glue. Dextrin can be used as a printing paste in textile printing and dyeing. |
| identification test | take about 1g of sample, suspend in 20ml of water, add several drops of Iodine test solution (TS-124), should appear dark blue to red-brown. Its infrared absorption spectrum should be in accordance with figure 10107. |
| toxicity | ADI is not specified (FAO/WHO,2001). GRAS(FDA,§ 184.1277,2000). |
| usage limit | FAO/WHO(1984,g/kg): broth, soup according to GMI; shannon cheese (in cream mix) 5; Heat-treated flavored yogurt and its products 10 after fermentation; Mackerel and canned fish 60 (only in packaging material); Cold drinks 30. |
| production method | unmodified natural starch from cereals or rhizome plants (e. G., corn, sorghum, potato, arrowroot, wheat, rice, cassava, sago, etc.), by heating or heating in the presence of a suitable food grade acid and buffer to partially hydrolyze. Dry with hydrochloric acid (less than or equal to 0.15%) or phosphoric acid (less than or equal to 0.17%) from the treatment. enzymatic method uses corn, wheat, dried potato and other natural starch as raw materials, with 0.15% hydrochloric acid or 0.17% phosphoric acid heat treatment, starch partial degradation and get the finished product. |
