Fruktooligosakkarideja

Fruktooligosakkarideja, also known as fructooligosaccharides (FOS), are a type of prebiotic fiber found naturally in many fruits, vegetables, and grains. They are composed of a chain of fructose molecules linked together by beta-2,1 glycosidic bonds, with a degree of polymerization ranging from 2 to 10. FOS are not digestible by human enzymes, making them resistant to digestion and absorption in the small intestine. Instead, they reach the large intestine, where they serve as a substrate for the growth and activity of beneficial gut bacteria.

The primary sources of FOS include chicory root, garlic, leeks, onions, and asparagus. FOS are also produced industrially through enzymatic hydrolysis of sucrose, which results in a mixture of FOS with varying degrees of polymerization. FOS have been extensively studied for their potential health benefits, including prebiotic effects, which promote the growth of beneficial gut bacteria and improve gut health. They have also been shown to have a low glycemic index, making them suitable for individuals with diabetes or those looking to manage their blood sugar levels. Additionally, FOS may have potential applications in the food industry as a functional ingredient, contributing to the development of probiotic foods and beverages. However, further research is needed to fully understand their health effects and optimal dosages.
