The resistant dextrin is a low-calorie dextran which is processed from starch, it’s methanated by starch saccharification and a low molecular weight water-soluble dietary fiber. In addition to the α-1, 4 and α-1,6 glucosides originally possessed by starch, it also possesses α-1, 2 and α-1,3-linked glucosides, which are difficult to digest structures of human body. Low-calorie soluble food materials have broad prospects for development in the food industry.
The resistant dextrin is a natural small molecule water-soluble dietary fiber obtained by enzymatic hydrolysis, fibrosis, purification and drying using corn starch as raw material. It is a white to pale yellow powder, a colorless or light yellow liquid containing a large amount of starch crosslinks and will not be hydrolyzed by human digestive enzymes.
※Introduction
| English Name | Resistant Dextrin | |
| Raw material | Source food starch | |
| CAS no. | 90-53-9 | |
| EINECS no. | 232-675-4 | |
| Molecular formula | C18H32O16 / (C6H10O5)n | |
| Molecular weight | 504.4371 | |
| Production process | A dietary fiber prepared by the use of food starch as a raw material and subjected to dextrinization under acidic conditions. | |
| Quality requirements | Appearance | Amorphous powder, no visible to the naked eye |
| Color | White to light yellow powder | |
| Odor、taste | No smell, slightly sweet taste | |
| Impurity | No external vision visible foreign impurities | |
| Total dietary fiber，% | ≥82.0（According to AOAC2009.01） | |
| Moisture，% | ≤6.0 | |
| Ash，% | ≤0.5 | |
| Sulfur dioxide residue (SO2) | ≤0.04 | |
| pH (10% aqueous solution) | 4.0-6.0 | |
| Performance | Low viscosity – the viscosity of the aqueous solution is very low, and the change in viscosity value with the shear rate and temperature changes is small. | |
| Wetting – can act as a wetting agent to prevent or slow down the undesirable changes in wet foods, so that the food is neither dehydrated nor hydrated. | ||
| Water-soluble – has good water solubility and can prepare aqueous solutions with concentrations up to 80%. It is insoluble in ethanol but partially soluble in glycerin. | ||
| Stability –25℃, 45℃and 60℃ conditions, can be stably stored in the open environment for more than 90 days, the shelf life can be up to 2 years in a closed environment. | ||
| Meltability – The amorphous powder melts at temperatures above130℃ and cools to form a clear, glassy material with a brittle structure similar to that of hard candy. | ||
| Application | Pharmaceuticals, baking, confectionery, beverages, seasonings, meat products and frozen products. | |
※Function
1. Anti-caries;
2. Neutral taste, low moisture absorption;
3. Low glycemic index, low insulin index, low calorific value;
4. Promote the absorption of minerals, especially the absorption of calcium and magnesium;
5. High digestion tolerance, high stability (acid, thermal stability);
6. Help reduce serum cholesterol and regulate blood lipids, blood sugar levels;
7. High stability in food processing (very easy to dissolve, low viscosity);
8. Laxative, promote the proliferation of human probiotics, maintain the micro-ecological balance in the body, prevent intestinal mucosal atrophy;
9. Easy to apply (unique stereo structure, so that its powder has good fluidity, dispersibility and solubility).
