Fructooligosaccharide vs. Oligofructose — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on May 6, 2024
Fructooligosaccharides and oligofructose refer to the same class of short-chain fructose molecules, often used interchangeably in dietary contexts.

Key Differences
Fructooligosaccharide (FOS) and oligofructose are both derived from the breakdown of inulin, a type of dietary fiber found in various plants. Whereas the term "oligofructose" is sometimes used to specifically describe a shorter-chain subset of FOS, the differences are minimal, and the terms are often used interchangeably.
Both FOS and oligofructose serve as prebiotics, which means they stimulate the growth of beneficial bacteria in the gut. This enhances digestion, aids in nutrient absorption, and improves overall gut health. However, oligofructose, being a shorter-chain molecule, might be slightly more fermentable than some of the longer chain lengths included in broader FOS products.
In the food industry, FOS is added to foods as a sweetener, texture enhancer, and a fiber supplement. On the other hand, oligofructose is often highlighted for its prebiotic properties in functional foods and dietary supplements, aimed at enhancing digestive health.
From a nutritional standpoint, both FOS and oligofructose are considered low-calorie sweeteners and do not cause a spike in blood sugar levels, making them suitable for diabetics. However, oligofructose’s shorter chain length may make it more soluble and slightly sweeter than some forms of FOS.
Regarding availability, FOS is commonly found in a wide range of foods, including onions, garlic, and bananas. Oligofructose, while also present in these foods, is often extracted and purified for use in food products and supplements where specific prebiotic benefits are desired.

(carbohydrate) Any of a class of oligosaccharides composed of fructose molecules, used as sweeteners.
Common Curiosities
Can fructooligosaccharide help with digestion?
Yes, FOS improves digestion by promoting the growth of beneficial gut bacteria.
Is oligofructose good for diabetics?
Yes, because it is a low-calorie sweetener that does not cause significant blood sugar spikes.
What is fructooligosaccharide?
Fructooligosaccharides are oligosaccharides made from short chains of fructose, used as dietary fiber and prebiotics.
How are fructooligosaccharides used in food production?
They are used as sweeteners, texture enhancers, and to increase the fiber content of foods.
What is the best way to incorporate FOS into my diet?
Start slowly to prevent digestive issues and include it in foods like yogurt or smoothies.
Where can I find natural sources of fructooligosaccharides?
Natural sources include garlic, onions, bananas, and chicory root.
Is fructooligosaccharide natural or synthetic?
It can be both; naturally found in plants and can be synthesized for food products.
What makes oligofructose different from other types of FOS?
Oligofructose consists of particularly short fructose chains, making it more fermentable and soluble.
What is oligofructose?
Oligofructose is a type of fructooligosaccharide with shorter fructose chains, known for its prebiotic properties.
