| Product Status | This product is a white or off-white amorphous powder, odorless, with a slightly sweet taste. It is easily soluble in boiling water and insoluble in ethanol or ether. According to relevant standards, strict limits are imposed on indicators such as loss on drying and heavy metal content of dextrin. For example, for loss on drying: take this product, dry it at 105°C to constant weight, and the weight loss shall not exceed 10.0%; for heavy metals: take the residue left under the item of residue on ignition, inspect in accordance with the specified method, and the heavy metal content shall not exceed 20 parts per million. All indicators of the dextrin produced by the company meet or exceed national standards and industry standards, ensuring reliable product quality. |
| Packaging Specification | Woven bags lined with pharmaceutical-grade polyethylene film bags, 25 kg per piece |
| Product Category | Filler, Disintegrant, Binder, Forming Agent, Thickener, Emulsifying Stabilizer |
| Specific Uses | In the pharmaceutical industry, dextrin is mainly used as a binder for pharmaceutical preparations. It can enhance the cohesion between drug powders and make dosage forms such as tablets easier to form; In the food industry, it can be used as a thickener, stabilizer and filler in beverages, candies, baked foods, etc., which can improve the physical properties of food and extend the shelf life of food; In the papermaking, textile and other industries, dextrin also plays an important role. For example, it is used for paper sizing to improve the water resistance and strength of paper, and as a printing paste in textile printing and dyeing to help dyes adhere evenly to fabrics. |
