A normal diet can provide 5-10 g of non-digestible oligosaccharides per day, which are derived from vegetables (mainly fructooligosaccharides). For healthy adults, the effective dose of oligosaccharide is 5-10g per day, and less than 5g is generally considered to be insufficient.
selection principle
Isomaltose, fructooligosaccharide, galactooligosaccharide, etc. can be selectively fermented by intestinal flora after entering the large intestine (mainly used by bifidobacteria and lactic acid bacteria, not by harmful bacteria), so All are excellent prebiotics.
The main difference between them lies in the different degrees of utilization by the intestinal flora, which are manifested in the differences in the proliferation degree of different beneficial bacteria, the inhibition degree of harmful bacteria, acid production and gas production. In practical applications, the most suitable prebiotic varieties can be selected for different consumer groups and food types according to the different characteristics of these oligosaccharides
