In the fast-growing functional ingredients market, Fructooligosaccharides (FOS) has become a staple for its recognized prebiotic benefits. For B2B buyers, understanding the manufacturing process behind this key ingredient can provide valuable insights into quality assurance and supplier reliability. As a leading manufacturer and supplier of FOS (CAS No. 308066-66-2), we are pleased to outline the journey from raw material to a high-quality prebiotic ingredient.

The production of Fructooligosaccharides typically begins with a readily available carbohydrate source, most commonly sucrose or starchy materials like corn. Through enzymatic conversion, specific enzymes are used to modify the structure of these carbohydrates, linking fructose units together to form short-chain oligosaccharides. This process requires precise control of temperature, pH, and enzyme concentration to ensure the formation of FOS with the desired chain lengths and purity. The primary enzymes involved are fructosyltransferases, which catalyze the transfer of fructose units. This enzymatic method is crucial for achieving the specific beta-(2-1) linkages characteristic of FOS, distinguishing them from other oligosaccharides.

Following the enzymatic conversion, the crude FOS mixture undergoes several purification steps. These typically include filtration to remove residual enzymes and insoluble materials, chromatography to separate FOS from other sugars like glucose and fructose, and decolorization processes to achieve a clear product. Finally, the purified FOS solution is concentrated and dried, usually through spray drying, to yield the final white powder form. This meticulous purification is what ensures the high purity (often FOS-95% or higher) and desirable sensory characteristics, such as mild sweetness, that manufacturers seek. Quality control is integrated throughout this process, with regular testing to ensure compliance with specifications like GB/T23528-2009.

For procurement managers and R&D scientists, understanding these manufacturing principles underscores the importance of selecting a reputable FOS supplier. A reliable manufacturer will be transparent about their production methods, quality control measures, and the resulting product specifications. Key parameters to look for include the assay of total FOS, the absence of excessive free sugars (glucose and fructose), microbial limits, and physical properties like particle size and moisture content. We, as a manufacturer, adhere to strict quality management systems to guarantee that every batch of our FOS meets these stringent requirements. This commitment ensures that when you buy FOS from us, you receive an ingredient that performs consistently in your applications, whether in dairy, beverages, or health supplements.
