Problems solved by technology

[0012] Due to the low pH value of the existing polydextrose, the taste is bitter and astringent. In milk-containing foods, excess acid will cause milk to coagulate
Moreover, the application of high residual glucose in some foods will produce Maillard reaction, which is not suitable for diabetic patients, and the taste is slightly bitter and astringent, which is not convenient for the promotion and application of related food industries.
But at present, there is no sugar-free polydextrose and its production method

Embodiment 1

[0031] Example 1 The production process of polydextrose A

[0032] 267kg of oral dextrose, 30kg of food-grade D-sorbitol and 3kg of food-grade citric acid in water, mixed thoroughly, added to a specially made 500L stainless steel polymerization kettle, and reacted for 4 hours at 140°C to 180°C under a pressure of less than 300mHg. Obtain polydextrose A type product.

Embodiment 2

[0033] Example 2 The production process of polydextrose A aqueous solution

[0034] Add 2700kg of pure water into a stirring and jacketed stainless steel dissolution kettle, preheat it to 40°C with steam, add 300kg of polydextrose A raw material under stirring, and stir until it is completely dissolved to obtain a 10% polydextrose A aqueous solution .

Embodiment 3

[0035] Example 3 Production process of sugar-free polydextrose

[0036] With the 10% polydextrose A aqueous solution produced in Example 2, on the nanofiltration membrane unit, at 40 ° C, under the pressure of 17.4 to 22.5 bar, first circulate and pre-concentrate to 1 / 2 of the volume, then wash and filter, and divide For the second time, pure water is added each time to make up to the volume of the raw material solution, and the final diafiltration concentration reaches more than 21%.

Abstract

The invention relates to foodstuff meal fiber and a production method, specifically to a sugar-free polydextrose and a production method thereof. The invention is characterized in that average molecular weight of the sugar-free polydextrose is 2000-4500Da, content of the polydextrose is more than or equal to 97%, content of glucose is less than or equal to 0.25%, content of 5-hydroxymethylfurfural is less than or equal to 0.01%, and content of 1,6-anhydrous glucose is less than or equal to 0.2%. The sugar-free polydextrose prepared by the present invention has advantages of high purity, low residual monosaccharide, excellent product performance, good taste, high content of effective component, and no need of introducing novel bad component. The production method of the sugar-free polydextrose has characteristics of high yield, low production cost, and simple and standard process.

Description

technical field [0001] The invention relates to food dietary fiber and its production method, in particular to a sugar-free polydextrose and its production method. Background technique [0002] Polydextrose (polydextrose) is a kind of water-soluble dietary fiber, which is white or off-white powdery solid (can also be made into wheat yellow or colorless liquid), easily soluble in water, solubility 70-80%, 10% aqueous solution The pH value is 2.5-7.0, and it has no special smell. It is a food component with health care function, which can supplement the water-soluble dietary fiber needed by the human body. [0003] Polydextrose can regulate the intestines, regulate blood sugar and blood lipids, and can be widely used as dietary fiber in various functional foods. In addition, it also has the following features: [0004] (1) Low-calorie, non-carious: its calorie is about a quarter of that of ordinary carbohydrates (16.5kJ / g), and the calorie of sugar-free polydextrose is lower...
