Fructooligosaccharides, also known as fructooligosaccharides, are a mixture of1~ 3 fructosyl groups combined with fructosyl groups in sucrose through β (2-1) glycosidic bonds to produce fructosyl trisaccharides, fructosyl tetrasaccharides and fructosyl pentasaccharides.
100g dry weight Jerusalem artichoke contains about 60-70g inulin, which is a fructan connected by linear β-2,1-glycoside chain, and its end is a sucrose group. Therefore, Jerusalem artichoke powder was hydrolyzed by endoinulinase and refined to obtain fructooligosaccharide syrup.
Extended data
Function of Fructooligosaccharide (FOS): Fructooligosaccharide is a natural active substance. The sweetness is 0.3-0.6 times of sucrose. It not only keeps the pure sweetness of sucrose, but also is sweeter than sucrose. It has the health care functions of regulating intestinal flora, proliferating bifidobacteria, promoting calcium absorption, regulating blood lipid, regulating immunity, and resisting dental caries.
Galactose has strong acid resistance and heat resistance, and will not lose its original characteristics due to high temperature sterilization and decomposition of human gastric acid during processing, while fructooligosaccharides do not have these characteristics. Galactooligosaccharide can be effectively utilized by both Bifidobacterium B and Lactic Acid Bacteria A.. Oligosaccharides such as fructooligosaccharides FOS can only be utilized by Corynebacterium Lactate A, but not by Corynebacterium bifidum B..
