Problems solved by technology

[0009] Extract from natural plants, the cost is high, the acid-base conversion method has the residue of acid (such as hydrochloric acid) in addition to the bad effect, the enzymatic method has complicated operation, many steps, and the problem that the product is difficult to control. The chemical synthesis method is to use chemical Aggregators polymerize non-dietary fiber monosaccharides and disaccharides into dietary fiber, but so far there are not many successes
[0010] The preparation of dietary fiber with monosaccharides and disaccharides is a research hotspot. Existing studies believe that the polymerization of monosaccharides and disaccharides requires the presence of epoxy groups in the sugars. Therefore, the monosaccharides or disaccharides must be epoxidized before they can be polymerized. Moreover, the conditions of the polymerization reaction are relatively strict, so there are not many successful ones at present.

Embodiment 1

[0131] Embodiment 1 (phosphorus oxychloride is the modified modified sugar that modifier prepares glucose):

[0132] Each of the three groups of glucose is 1 kg, respectively dissolved in 3 kg of sodium hydroxide aqueous solution, poured into 1ml, 3ml, 5mlg of phosphorus oxychloride while stirring, and stirred at room temperature (or heating) for 10 hours and 15 hours to carry out the modification reaction , gradually add a little salt during the stirring process. Then stand for 24 hours and dry to obtain three groups of modified modified sugars, which are respectively pulverized and packaged.

Embodiment 2

[0133] Embodiment 2 (epichlorohydrin is the modified modified sugar that modifier prepares sucrose):

[0134] Each of the three groups of 1 kg of sucrose was dissolved in 5 kg of 5% NaOH solution; then 2100 ml of peanut oil and 35-70 ml of Span60 were used to prepare the oil phase and heated to dissolve. Add sugar solution to each separately. Stir well, add 1g, 3g, 5g of epichlorohydrin respectively; react at 35-60 degrees Celsius for more than 6 hours; let stand to separate and remove the oil phase, wash with ethanol acetone three times, and dry at 80 degrees Celsius.

Embodiment 3

[0135] Embodiment 3 (sodium trimetaphosphate is the modified modified sugar that modifying agent prepares glucose and sucrose):

[0136] Three groups of 0.6 kg of glucose and 0.4 kg of sucrose were respectively dissolved in 3 kg of water (or 3% NaOH solution), and 3 g, 5 g, and 10 g of sodium trimetaphosphate were poured in while stirring. Stir at room temperature (or warming) for 10 hours and 15 hours for modification reaction, then stand for 48 hours and dry to obtain three groups of modified modified sugars, which are crushed and packaged separately.

Abstract

This invention publishes a modification of monosaccharides and / or disaccharides with modifiers and the modified saccharides. It further publishes the preparation method for the modified saccharides and their application in dietary fibers, anti-obesity drugs and health products. This invention enlarges the application of monosaccharides and disaccharides and promotes their exploitation value. It has the advantages of simple preparation, facile raw materials and low cost and is thus of great industrial practicability.

Description

technical field [0001] The invention relates to a modified modified sugar prepared from monosaccharide or / and disaccharide as a raw material, and also relates to a preparation method of the modified modified sugar and an application of the modified modified sugar, belonging to the field of sugar processing. Background technique [0002] There have been many studies and reports on the role of dietary fiber in participating in the physiological regulation of the body. Dietary fiber is mainly some sugar polymers, including some oligosaccharides, such as xylooligosaccharides, oligoglucose, etc., and some polysaccharides, such as pectin and vegetable gum. This type of sugar is recognized and defined as dietary fiber by the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO). [0003] The international definition of dietary fiber is "a general term for plant-based edible parts or similar carbohydrates that cannot be digested and a...
