Overview | isomaltooligosaccharides are mainly composed of isomaltose, panose, isomaltotriose and other oligosaccharides. Because of Alpha 1,6 glycosidic bond binding, also known as differences in oligosaccharides. Isomaltooligosaccharide has low viscosity, heat resistance, acid resistance, moisture retention, prevent starch aging, low moisture activity and net bacteria, difficult fermentation and other general characteristics. The sweet taste and texture are also more palatable and smooth. |
advantages | milk sugar is mainly produced by isomaltooligosaccharide, and its products have the following advantages:(1) the candy is glossy, high transparency. The appearance of milk sugar is like beauty, sweet, pure and pleasant, not greasy. (2) not easy for human digestion and absorption, low calorific value. (3) after eating oral refreshing, will not be used by oral microorganisms, do not have to worry about dental caries. (4) long-term use can promote the proliferation of human intestinal Bifidobacteria. The Bifidobacterium can synthesize Vitamin B1, B2, B6, K, niacin, folic acid, etc., and slowly absorbed by the human body. In addition, it also exerts a series of beneficial effects on human health. |
detection | a method for the detection of isomaltose, isomaltotriose, maltose and panose in yellow rice wine, (I) preparation of sample to be tested: Take 0.5-g sample of yellow rice wine and place it in a mL volumetric flask, add Grade 1 water to the scale, shake well and then stand still, (II) purification of samples to be tested: take C18 solid phase extraction column (1000mg/6mL), add 1.5ml step (I) the effluent to be purified is discarded, and then 1.5 of the liquid to be purified is added to collect the effluent, and the sample solution to be measured by ion chromatography-tandem mass spectrometry after passing through a 0.22 μm nylon filter membrane; (III) preparation of mixed standard solution: The mixed standard working solutions of isomaltose, isomaltose, maltose and panose were prepared. The concentration gradient of the mixed standard working solution was 0.5 μg/mL and 1.0 μg/mL,5.0 μg/mL,10.0 μg/mL,25.0 μg/mL,50.0 μg/mL; (IV) detection of the sample: Step (II) the sample solution to be measured and the standard working mixed solution in step (3) were injected on the ion chromatography-tandem mass spectrometer to obtain isomaltose, isomaltotriose, maltose, the concentration of panose is the abscissa, and then the peak area of isomaltose, isomaltotriose, maltose and panose quantitative ion pair in the standard solution is the ordinate, then the concentration of isomaltose, isomaltotriose, maltose and panose in the sample solution to be measured was calculated by working curve. |
biological activity | Isomaltotriose is a sugar obtained by enzymatic hydrolysis of glucose in leucostoc mesenteroides NRRL B- 512. |
