Problems solved by technology

In the production process of polydextrose, it is the key to obtain the product with high purity and white color to carry out proper post-treatment to it, but the post-treatment process efficiency of the decolorization, purification, concentration and drying adopted in the prior art is low, resulting in The high-quality polydextrose powder is not only not white enough, generally light yellow, but also has poor yield and low purity.

Embodiment 1

[0044] 275kg of glucose, 40kg of sorbitol and 1.7kg of fumaric acid were evenly mixed, and reacted for 3 hours at a temperature of 182°C and a negative pressure of -0.065Mpa to obtain crude polydextrose.

[0045] Add secondary filtered water at 60°C to the crude polydextrose until the final concentration reaches 10%. At a temperature of 30°C and a pressure of 0.6 MPa, a polysulfone membrane with a molecular weight cut-off of 10 kDa is used for ultrafiltration to obtain a filtrate; the filtrate is then decolorized by column-type granular activated carbon to obtain polydextrose liquid, column-type particles The decolorization temperature of the activated carbon was 50 °C, and the flow rate was 4 mL / min.

[0046] The decolorized polydextrose solution is treated with an ion exchange resin, and the obtained sugar solution is concentrated to make the concentration of the polydextrose solution reach 50%.

Embodiment 2

[0052] Mix 1.2kg of fumaric acid, 0.3kg of malic acid and 0.2kg of tartaric acid to obtain a mixed acid.

[0053] 275kg of glucose, 40kg of sorbitol and 1.7kg of the mixed acid were mixed uniformly, and reacted for 3 hours at a temperature of 182°C and a negative pressure of -0.065Mpa to obtain crude polydextrose.

[0054] Add secondary filtered water at 60°C to the crude polydextrose until the final concentration reaches 10%.

Embodiment 3

[0061] Take 278kg of glucose, 37kg of sorbitol and 1.9kg of malic acid, mix them evenly, and react for 4 hours under the conditions of a temperature of 185°C and a negative pressure of -0.06Mpa to obtain crude polydextrose.

[0062] Secondary filtered water at 65° C. was added to the crude polydextrose until the final concentration reached 25%. At a temperature of 60°C and a pressure of 1.8 MPa, a polysulfone membrane with a molecular weight cut-off of 10kDa is used for ultrafiltration to obtain a filtrate; the filtrate is then decolorized by column-type granular activated carbon to obtain polydextrose liquid, column-type particles The decolorization temperature of the activated carbon is 70°C, and the flow rate is 10mL / min.

[0063] The decolorized polydextrose solution is treated with an ion exchange resin, and the obtained sugar solution is concentrated to make the concentration of the polydextrose solution reach 75%.

Abstract

The invention provides a production method of polydextrose, and the production method is as follows: performing a polycondensation reaction of glucose under effects of a catalyst and a polyol to obtain a polydextrose crude product; performing ultrafiltration on the polydextrose crude product to obtain filtrate; performing decolorization treatment on the filtrate to obtain a polydextrose solution; separating and purifying the polydextrose solution, concentrating, and drying to obtain the polydextrose. Through ultrafiltration of the obtained polydextrose crude product, most pigments are removed, and other impurities can be removed, then through cooperative use with the subsequent decolorization, separating and purifying, concentrating, drying and other processes, the pigments and other impurities can be removed more completely, and the finally obtained polydextrose is high in finished product rate and high in purity. Further, a polysulfone membrane is selected and used for ultrafiltration, so that the pigments and other impurities can be removed more completely, and the ultrafiltration effect is good.

Description

technical field [0001] The invention relates to the field of food additives, in particular to a production method of polydextrose. Background technique [0002] Dietary fiber is a nutrient that is not easily decomposed by digestive enzymes. It mainly comes from the cell walls of plants and sugars in natural foods. According to its solubility, it can be divided into water-soluble dietary fiber and water-insoluble dietary fiber. Among them, water-soluble dietary fiber can slow down the digestion rate and promote the excretion of cholesterol, thereby helping to control blood sugar and cholesterol in the blood within an ideal range. In addition, water-soluble dietary fiber can also help reduce insulin and triglyceride levels, so nutritionists call it the "seventh nutrient". [0003] Polydextrose is a high-quality water-soluble dietary fiber, which has been approved as a healthy food ingredient by more than 50 countries including China and the United States. In our country, po...
