Introduction of Fructooligosaccharide (FOS)
FOS is a type of oligosaccharide, which is composed of 2 to 9 fructose units connected by β(2→1) glycosidic bonds. Common forms of FOS include sucrose triose, sucrose tetraose, and sucrose pentose.
Main sources of FOS
-
Ricchio lettuce
-
Onion
-
Garlic
-
Bananas
-
Honey ...
Physiological functions of FOS
-
Natural prebiotics
-
Promote mineral absorption
-
Regulate lipid metabolism
Physical and chemical properties of FOS
-
Physical properties: Good water solubility, low calories, lower sweetness than sucrose, and good taste.
-
Chemical properties: High thermal stability, acid resistance, and can remain stable during processing.

Published Data
This article describes a simple chromatographic technique that has been developed and validated for the quantitative analysis of total FOS content during fermentation. The authors used high-performance liquid chromatography (HPLC) coupled to a differential refractive index detector to monitor FOS production during sucrose fermentation by Aspergillus aculeatus. This method applies to both laboratory and industrial settings, allowing tracking of large-scale FOS production and control of the main substrate (sucrose) as well as secondary byproducts such as glucose and fructose.

FAQs
Q1: What analysis methods do you use to detect FOS?
A1: We mainly use HPLC combined with evaporative light scattering detection (ELSD) or mass spectrometry (MS) for FOS analysis. These methods accurately separate and quantify the different components of FOS with high sensitivity and precision.
Q2: Could you detect FOS residues in complex matrices?
A2: Yes, we have extensive experience in dealing with complex matrices (such as high-fat foods or plant extracts) and ensuring accurate determination of FOS residues by optimizing pretreatment and detection methods.
