Abstract
The invention discloses cane sugar with low human body absorption and a preparation method thereof. Because the sugarcane fibers are combined with the sucrose molecules, the absorption of the human body to the sucrose is reduced due to the macromolecular effect of the sugarcane fibers, the sugar intake of the human body is effectively reduced, and the sugarcane is novel healthy sucrose. In addition, the invention utilizes the bagasse which is produced in a large amount in the sugar manufacturing process, thereby playing a role of environmental protection.
Description
Technical Field
The invention relates to the field of food, in particular to the field of edible sucrose.
Background
With the better life quality of people, the intake of sugar becomes more and more, which leads to the increasing proportion of the obese people at present.
In recent years there has been an increasing interest in health, and many alternatives to sucrose, such as sugarless colas, such as sweeteners, have emerged. However, the taste of sugar-free products is obviously not satisfactory for users, and sweeteners such as aspartame can be decomposed into methanol, aspartic acid and phenylalanine in human bodies, and researches show that the levels of formic acid (formicacid) and alanine (alanine, an amino acid) in urine of people with hypertension are higher. One possible explanation is that these people drink large quantities of soda containing aspartame, causing hypertension and high levels of aspartame metabolites.
Therefore, people need to develop a product which keeps the taste of the cane sugar and is completely harmless to human bodies.
Disclosure of Invention
In order to solve the problems, the invention discloses a low human body absorption sucrose. The invention modifies the bagasse, combines the fiber and the cane sugar molecules in a certain way, thereby reducing the absorption of human body to cane sugar.
The whole preparation process comprises three steps of (1) preparing the sugarcane fiber velvet; (2) bridging of sugarcane fiber flock and sucrose molecules; (3) and (5) crystallizing sucrose to prepare.
(1) Preparing the sucrose fiber velvet:
the preparation method comprises adding 10g bagasse into a reactor containing 30g-1000g and 30% hydrogen peroxide, stirring for 3-5 hr, and filtering to remove filtrate.
The product of the first step is added to a reactor containing 30-1000g of 10% aqueous sodium hydroxide solution, stirred for 3-5 hours, and filtered to remove the filtrate.
The product of the previous step was filtered repeatedly with water until the solution PH = 7. Distilling to remove most of water under ultrasonic condition, and vacuum lyophilizing to obtain the final product. FDS-2000 from Tokyo physicochemical instruments was used as a freeze dryer.
(2) Sugarcane fiber flock and sucrose molecular bridging:
adding 1g of the treated sugarcane fiber velvet into 200g of anhydrous cyclohexanone, starting stirring, adding 0.2-0.5g of adipic anhydride, and reacting for 3 hours until the anhydride reaction is complete.
0.05g of trifluoromethanesulfonic acid and 10-20g of sucrose were added to the reactor, and the reaction was continued until the carboxylic acid reaction was complete.
(3) And (3) sucrose crystallization preparation:
adding 400g of deionized water into the solution, shaking for layering, collecting a water phase, washing an organic phase for 3 times, and finally combining the 3 times of water phases to obtain the bridged solution containing the sugarcane fiber velvet and the sucrose.
Adding the solution containing the sugarcane fiber velvet and the cane sugar which are bridged into a reactor, keeping the temperature at 60-80 ℃, stirring at the speed of 20-40 r/min, keeping ultrasonic oscillation, crystallizing the cane sugar solution after evaporating most of water, and finally separating and drying the crystals to obtain the product.
In the scheme, the invention modifies the bagasse which is a byproduct in the sucrose industry to form small-size sugarcane fiber velvet. This can reduce sucrose absorption without affecting the appearance.
In the second step, adipic anhydride is used for bridging, mainly because adipic anhydride is a domestic allowable food additive, and even if residue exists, the adipic anhydride does not cause harmful damage to human bodies. The bridging ratio of the sugarcane fiber velvet and the sucrose is 1:10-1:20, when the proportion of the sugarcane fiber velvet is too large, a turbid phenomenon can obviously occur in a system, the appearance is influenced, and the sweetness is reduced too much due to the fact that the bridging ratio is too large. When the ratio is too small, the effect of reducing sucrose absorption is not significant.
In the third step of crystallization process, ultrasonic oscillation must be kept, the phenomenon of agglomeration of the sugarcane fiber velvet is prevented, and in addition, because the sugarcane fiber velvet is added, the sucrose is easier to crystallize, and the production efficiency is improved.
The technical scheme provided by the embodiment of the invention has the following beneficial effects:
the sucrose obtained by the synthesis method provided by the embodiment of the invention is connected with the sucrose by using adipic anhydride, and the sucrose cannot be absorbed by human body due to the characteristics of the fiber, so that the sugar intake is reduced.
Meanwhile, the health-care food is rich in dietary fibers, so that the health-care food can mechanically stimulate the intestinal peristalsis and accelerate the intestinal digestion function, and has a health-care effect.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
The main function of the invention is to reduce the absorption of human body to cane sugar, so the blood sugar rise value after eating is detected.
The test method comprises the following steps:
5 subjects, A/B/C/D/E, were selected, wherein A, B was female, C, D, E was male, A, C was lean and B, E was fat, respectively. 75g of the sucrose of the present invention and the comparative example were administered for 9 days, respectively, and blood glucose values were measured after 1 hour after each day of administration. The final average was taken as the conclusion, the comparative example was commercial sucrose.
The combination of all the data shows that the sugar absorption of human body is obviously reduced on the premise of keeping the taste of the sucrose, and the maximum sugar absorption is reduced by 32.72%.
