概要
Polydextrose, also known as water-soluble dietary fiber, is a low-calorie, low-glycemic compound with characteristics of water-soluble dietary fiber and prebiotics. It is a polysaccharide produced by high-temperature melt polycondensation of naturally occurring glucose with small amounts of sorbitol and citric acid, belonging to randomly cross-linked glucose polymers. The chemical name of polydextrose is randomly cross-linked glucose polymer, with molecular formula represented as (C6H10O5)n, CAS number 68424–04–4, INS number 1200, and CNS number 20.022. Polydextrose appears as white or off-white solid particles, soluble in water, odorless and tasteless. It is a functional food component that can supplement the water-soluble dietary fiber needed by the human body. Polydextrose is a multifunctional soluble fiber that brings both nutritional and sensory advantages to modern food formulations. It serves as a low-calorie bulking agent that can partially replace sugar and fat—preserving creaminess, texture, and mouthfeel in reduced-calorie applications while enabling fiber enrichment. Polydextrose is widely used in the food industry, health food industry, pharmaceutical industry, and daily chemical industry. In the food industry, it is one of the most versatile and cost-effective ingredients, successfully applied in nutrition bars, cereal foods, baked goods, dairy products, beverages, jam products and fillings, chocolate, confectionery, and frozen foods. In the pharmaceutical field, it is used as a pharmaceutical excipient for tablet binders in wet granulation and direct compression tablet production. In the daily chemical industry, it is used as a humectant and bulking agent. In 2014, the National Health and Family Planning Commission explicitly stated that polydextrose can be managed as a common food ingredient, while it is also listed in GB 2760 as a food additive (thickener, raising agent, moisture retainer, stabilizer) and in GB 14880 as a nutrient fortifier for use in infant formula.
Appearance: White or off-white solid particles, odorless, tasteless. Crude product is light brownish-yellow powder with sour taste; refined product after neutralization is white flowable powder, odorless.
Molecular Formula and Molecular Weight: Molecular formula represented as (C6H10O5)n, average molecular weight approximately 2000, average degree of polymerization (DP) approximately 12, ranging from 2 to 120.
