Introduction
Fructose contains more fructose polymers, while oligofructose contains fewer. Fructose can lower cholesterol, regulate blood glucose, and prevent constipation. Oligofructose enhances calcium ion absorption and increases bone density. Fructose can inhibit harmful facial bacteria and reduce pigmentation. Oligofructose is commonly added to milk powder to help regulate microbial balance, making the milk powder easier to digest and absorb.
Fructose and fructooligosaccharides (FOS) differ in their fructose polymer structures, physiological effects, and applications.
1. Differences in Fructose Polymer Structure
Fructose typically contains a relatively high number of fructose units—often more than 20—whereas fructooligosaccharides contain fewer fructose units, generally less than 20.
2. Differences in Physiological Effects
Fructose functions as a water-soluble dietary fiber, helping to lower cholesterol levels, regulate blood glucose, and effectively prevent constipation. Fructooligosaccharides are naturally present in vegetables and fruits and possess potent bifidogenic activity as well as water-soluble dietary fiber properties. Appropriate intake enhances calcium absorption, thereby increasing bone mineral density. Moreover, FOS exerts protective effects on intestinal mucosal cells and inhibits the growth of harmful bacteria.
3. Differences in Applications
Fructose is commonly added to cosmetic products to suppress harmful facial bacteria, thereby effectively reducing hyperpigmentation. Fructooligosaccharides are frequently incorporated into infant formula to modulate gut microbiota balance, thereby improving digestibility and nutrient absorption.
