Cellodextrins are functional carbohydrates that are expected to be promising water-soluble dietary fibres. They can act as a prebiotic ingredient and, therefore, have a positive effect on health: Prebiotics are stimulating the immune system, regulating the gastrointestinal function or preventing from carcinogenesis for example. An important criterium for prebiotic components is that they are not digested by humans. Cello-oligosaccharides (COS), also known as cellodextrin meet this requirement and are, therefore, one of the main target products of the CARBAFIN project.
The recent publication explains the enzymatic production of COS at larger scale in order to bring the technology that has been proven previously, to the next level and to open the door towards industrial application. The CARBAFIN researchers from acib and TU Graz together with researchers from BOKU demonstrate the soluble COS production to approximately 100 gram per litre in a 20 mL reaction volume. The enzymatic reaction turned out to be very efficient and to provide a product with a very satisfying yield and purity from simple and expedient substrates. The stimulation of growth among probiotic bacteria was also shown.
