Also known as short-chain inulin consists of 2-7 fructose units. This type of inulin has higher solubility compared to longer-chain varieties. Short-chain inulin is often used in food products for its prebiotic properties and as a sugar substitute.
Since fructooligosaccharides (FOS) have a simple chemical structure (primarily beta-2-1-linked fructans) and are commonly found in diets (), it is expected that many microbes have evolved to utilize them and have the ability to degrade this simple linkage type. Moreover, the soluble nature of FOS allows easy microbial accessibility for its degradation.
