Researchers from University of Jyvaskyla Report New Studies and Findings in the Area of Carbohydrate Research

February 18, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators discuss new findings in Life Science Research. According to news reporting from Jyvaskyla, Finland, by NewsRx journalists, research stated, "This study describes the synthesis of carboxymethylxylan (CMX) and investigates its suitability as a film for packaging applications. High-purity polymeric xylan was extracted from commercial bleached birch kraft pulp and converted to CMX with three different degrees of substitution (DSs)."

The news correspondents obtained a quote from the research from the University of Jyvaskyla, "The water vapor sorption, mechanical, and barrier properties of the films prepared from CMX were tested. Increasing DS of CMX films resulted in an increase in elongation at break and a decrease in tensile strength and Young's modulus. The DS also affected the barrier properties of the films. CMX films with higher DS showed improved (reduced) oxygen permeability (OP), and the water vapor permeability (WVP) increased with DS."

According to the news reporters, the research concluded: "It was demonstrated that the carboxymethylation of xylan recovered from industrial side-streams and its conversion to packaging films could be a viable option to valorize xylan."
