First, fructooligosaccharide is a kind of sugar, because no enzyme in normal people can hydrolyze fructooligosaccharide, a carbohydrate! So it is not easy to be absorbed by the human body, so diabetics can also take it! Fructose is the most common hexose. It exists in honey and fruits and combines with glucose to form sucrose for daily consumption. Fructose contains 6 carbon atoms and is also an isomer of monosaccharide and glucose. It exists in a large amount of fruit juice and honey in a free state, and fructose can also combine with glucose to produce sucrose. Pure fructose is a colorless crystal with melting point of 103 ~ 105℃. Not easy to crystallize, usually a viscous liquid, easily soluble in water, ethanol and ether.
Second, the difference between sugar and fructooligosaccharide is a natural active substance. It is an indigestible carbohydrate existing in nature. Can not be absorbed by the human body, will not affect blood sugar and blood lipids. Instead, it is specifically decomposed and utilized by beneficial bacteria in the body, thus transforming it into a nutrient source and promoting the growth, reproduction and colonization of beneficial bacteria. White sugar, brown sugar, rock sugar and cotton sugar were originally extracted from sucrose or beet, and all belong to sucrose. White sugar tastes sweet and can be quickly absorbed and utilized by the human body, which can affect blood sugar.
Third, are fructooligosaccharides the same as oligosaccharides? Fructooligosaccharides and oligosaccharides have a sugar word but only one word, but they are not white sugar and brown sugar. Fructooligosaccharides are a kind of oligosaccharides and belong to the prebiotic family. The human body can't digest and absorb oligosaccharides, and oligosaccharides are decomposed and utilized by beneficial bacteria in the intestine, which is the so-called probiotic ration. Whether fructooligosaccharides or soybean oligosaccharides, isomaltooligosaccharides, stachyose, etc., can be helpful to the intestinal environment.
